    It's been ages since I posted any updates. The reason being a change of job now means I'm getting the train to work and the S4 is just sitting. The sensible thing to do would be to sell it but I don't really want to part with it. I've been trying to take it out every couple of weeks to stop it seizing up. So tonight I pop out and am surprised to see the coming home lights don't come on. The car starts first time but the radio is also off which is odd, I don't turn it off. Realistically it's been sitting for 3 weeks and it's been cold. I assume the battery has got low and some kind of self preservation / power save has kicked in as identically described here:

    https://www.audizine.com/forum/showthread.php/685786-2011-S4-Power-Saving-Mode

    Following a run out everything was back to normal.

    I doubt the battery is dying at 4 1/2 years old but will keep an eye on it. Fortunately I have a 50 mile trip tomorrow so should charge things up.

    Interesting as I had been thinking about the same. I am doing almost 1.5k miles a month so decided to buy an old MK5 for £900 that I don't have to worry about no matter what. The S4 has been sat outside and has not been driven in the last 2-ish weeks (well, slightly over 2).

    Now that you have mentioned seizing would you mind elaborating please. Makes me slightly nervous and paranoid.

    I’m in a similar situation, I now work away and the S4 just sits. Invested £60 in a trickle charger to keep the battery in good order.

    Not getting used in the middle of winter could easily kill a battery of that age. Keep in mind most battery warranties are 4-5 years.

    Hello @Tashfeen. Who made you a mod? :D

    The seizing up is simple things like the brakes. They are very crunchy after a few weeks off. Had one slightly binding for the first 30 yards to the end of my street the last run out. I'm conscious that the same is probably happening elsewhere on the car. It also seems to me that the fluids and such need circulating to do their job, anti corrosion, lubricating the aircon system, etc. I'm not a mechanic but it makes sense in my head. To that end I've been doing a 20-30 mile run every couple of weeks. I simply missed out on my routine recently due to, well, life really. :)

    . The brake thing I completely agree as it happened to me when it snowed last year. Drove the car after almost 3 weeks and stopped immediately to check the suspension /brakes. Couple of miles down the road the sound disappeared.

    I agree with the fluids and other bits and which makes me think it was maybe one of the reasons why she drank more engine oil last year compared to the year before where I used it a lot on short commutes? Since then the last 14k miles on the car almost 90% of them are motorway. The trip to London this Friday will be on S4so, will make sure I drive it like I stole it

    Generally if everything is in good order a couple of weeks won’t make anything too stuck. Brakes will likely be the worst you’ll need to worry about.

    A well maintained modern engine shouldn’t seize for a long time. Worst case you’ll get a little more top end noise until more of the oil circulates, even then I’d not expect that until it’s been sat for a few weeks.

    Even a short run every week or two should keep everything free. The battery will take a pounding though.

    Mine usually gets taken out on the weekend for an extended supermarket run / take the longest route to get there . It is just that I haven't driven it since I last washed it over 2 weeks ago - like her stay clean. Wife thinks I am mad

    @Tashfeen I find the other thing is it's amazing how dirty a car gets just sitting there. Washed mine and then it hadn't moved for two weeks and was covered in streaks etc.

    Very likely. I have had the same happen with mine, although for a shorter time because I used to leave the dashcam running even though it was in my garage, so the battery was drained to about 12V and then I didn't drive it for over a week.

    I believe that the AGM batteries used in stop/start cars are designed to be continually in a state of partial discharge so its only deep discharge you need to worry about. I'm usually driving mine at least once a week, but if I don't then I just put a charger on it. I think its good to charge a battery to full periodically anyway.

    I agree with @weekenny that there should be no risk of engine seizure. But I'd agree that it should be run periodically to keep the brake pads free of the discs, but more importantly to circulate and lubricate the aircon.

    As an update to this went out today and all was fine. Start/stop system was working which from what I've read is one of the first things to deactivate when the battery is on the way out.

    Quite by chance this morning, I was loading a destination in to the satnav ready for a journey I'm doing later, and a message came up saying the battery was weak and I should start the engine.It's zero degrees C outside right now, my battery's only three and a half years old, and I drove 20 miles yesterday.

    Should I be worried?

    Do you have VCDS Jeff, if so you check the battery status by going to:

    MODULE 19 (CAN-GETAWAY)

    Measuring Blocks - Select GROUPS 18,19 AND 20

    The above will give you an idea. To your question, I wouldn't get worried just now, I'll just blame the cold weather for the low battery message.

    PMSL Jeff . I'd like to think you'll be fine. The OE battery has a life span of 5 years or so the manual suggest. I am sure it will recharge itself with the journey you've planned later today.

    Panic time for me though I have to take out mine tonight for a good run just to make sure

    If you Google it looks like you can enable battery meter in the MMI @jdp1962.

    Just remembered I have a niggle to look at from yesterday. The indicator was not cancelling on right turns. You know how when you straighten the wheel it clicks off, mine wasn't doing that. Anyone know how it works?

    Available only on B8s and not on B8.5

    I had this issue on my B5 A4 and was resolved by replacing the stalk itself. Not sure about B8.5 though and how the mechanism works

    As far as I'm aware, you can remove the worry about not running the AC over long periods, most of not all B8> cars have a variable displacement AC compressor so it looks after the system by passing a low volume of gas+oil round the system when the engine is running and the Chiller is deselected or not required.

    I have carried out a Chiller performance/pressure test on my car within the past year and everything is okay - and Chiller use has been minimal as I live up the country a bit!

    When my S4 is not being used regularly, and that is 90% of the year, I make sure that I use it for a journey of minimum length 20 miles each way once a month - my car has only run just over 24K and is just short of 8 years old, even or because of that low usage, the lower arms have been spotted to have spreading/separating/splitting bushes - but that is typically an age thing with the weight of the drive train over the front suspension.

    Edit:- a bigger worry/concern should be the quality or condition of the fuel in the tank, to minimise "sweating" and so adding in water, you should keep the tank filled up at all times in winters if the car is left unused, similarly go into winter period with a fresh tank of winter grade petrol as petrol degrades very quickly nowadays. With fuel dropping off in quality, it is what it is and must happen if you minimise the car's use in winter so other than draining the system not much that you can do to avoid that. I too avoid using my 4WD S4 in winter, which is silly but it is easier to wash my wife's 6C Polo 1.2TSI 110PS SEL - and both cars have winter tyres/wheels fitted in winter!

    Thanks @rum4mo I was aware fuel degrades but didn't know about keeping the tank full. What's the reason for that?

    I also heard super unleaded loses some of its octane points if it sits. Not an issue for me on a standard car with 95 RON.

    Brilliant @rum4mo. Exactly the kind of information I was looking for. That puts my mind at ease. For me the tank is full all the time, well most of the time as I don't like the idea of having to search for the nearest Shell for fill-ups.

    Oh, and a yes about the washing

    Carista no, I am not sure about Torque Pro though. Having said that, my understanding is that you don't have the option of battery meter on B8.5 at all. Audi decided to remove it ...

    Remember that what you saw was not actually a warning but "helpful advice" by those nice German engineers who tend to implement wide safety margins into the software (like the ECU torque limit that you had removed). It's no different from when the stop/start decided to start the engine again when you are waiting at a red light: Nothing wrong with the battery - it just doesn't want the voltage to be too low.

    Annoyingly, the last fill up I did was at an Esso station and it had no UL+ option or I would have refilled it with UL+ for that reason.

    Tanks or any container sweating:- maybe more relevant to when tanks were made of steel, but really just the usual water vapour ending up being deposited on the inner surface of the "air void" in the tank and then ending up running down into the fuel, each time a really cold period has occurred and the temperature has risen back up. Now I don't mind if anyone knocks that idea out the window as we have plastic fuel tanks, in fact I'd be happy if someone did - please, as long as you know it is true. It is really just the same as you find when you drive a freezing car out of the garage into warmer wet air.

    My understanding of the EVAP systems in today's modern engines was that it allows the engine to burn off any vapours within the fuel tank. The system is designed to only burn the vapours when the engine is under a light load and there is positive pressure in the tank.

    I am not going to start the; "which fuel" debate here but in Shell Unleaded as well as V-Power there is some quantity of ethanol (no more than 5% s what she'll claims), which will also help absorb the vapours .

    That's not to say that we should therefore leave the fuel tanks empty for longer periods, as long as it is more than half full do we not think it will be OK?

    So, took the car out last night and drove it for around 25-ish miles and whilst everything was fine and there were only two things I noticed:

    1- Brakes - started working fine after about 4-5 hard stops. I have EBC Redstuff so, sure if the pads need to be 'warmed up' before they start working properly. I have never noticed before.

    2- Exhaust - this is what I have noticed on quite a few occasions now. If I start the car after say 2-3 weeks I usually expect the Milltek to 'roar' when I started but it doesn't. It sounds quite muted/subtle and doesn't give you that cold start noise.

    If however I am running the car on a daily basis, it is absolutely fine. For example, when I started the car this afternoon for my Oxford - Slough run, it sounded exactly how it should.

    What do we think can be the reason for this as I have now idea

    Yes, I'd think that all the high street petrols with have that bio stuff in it as it is the way forward - and the very reason that modern fuels "go off" quickly, I'll bet you 1/2 a mince pie that if you check fresh petrol it will be clear, 6 months down the road it will be straw coloured and another 6 months down the road it will be almost orange/brown - it wasn't always like that.

    Your point about the tank vent now being reasonably sealed wrt the outside world, maybe that cuts down the ingress of moisture a bit under the conditions I mentioned, seems like maybe there are some funky compounds/solutions in modern petrol that reduce into ?? and H20 with time anyway!

    PS Been a while since I've been in here

    Had an email from the Audi main Dealer in Ayr recently thanking me for servicing my car (my old S4)
    So it looks like someone's bought it in bonny wee Scotland

    Wondered whether the owner would make an appearance on here but so far they haven't

    When I got my MOT alert from my Audi dealer, I set about reg’ng on the Audi UK owners site, started getting blank pages instead of a usable form, gave up after a few attempts and tried again on an apple device, same thing, but eventually got in on a MS device, many failed attempts to add my car to my account, then finally got sorted only to find that my dealer did not seem to allow bookedtime slots for MOT! That was enough, I opened a complaint with Audi UK over their amateur approach to online booking systems. That resulted in a few “sorry” emails over the next few days, by which time I had booked the car in for an 08:45 arrival, took the car in, the service guy, special S and RS only handler, then he asked “any questions?” I asked when I would get the car back “17:30 sir” I ranted on about them only being Audi appointed agents and why can they not accept timed slots for MOTs that just caused a ping pong match of stupid responses, he finally said “what do we need to do for you?” I replied car back by lunchtime - and they agreed. So now I have had the post visit questionnaire - after every low score I repeated “why don’t you accept timed slots for MOTs?” as an explanation. Why do they think it’s smart to waste my time, maybe someone with phone me to explain this. Reading all the Audi UK bumf I got the impression that things were designed to make owners lives easy, seems not always. Audi UK did initially get back to my dealership, they phoned to book the car in for me, I said have you not checked your records held for me and that car, I have booked it in as I could not wait for ever for a response - then Audi UK emailed today to check if I still own an S4 as they have not heard from me for a long time? They really care, or do they.

    I'll need to keep my eye out for your old car, Ayr's in my region, shouldn't be hard to spot if the new owner has kept it nice and shiny like you did BH.

    They don't and ever will.

    I also don't think they check the records before contacting you. For example, the DSG on the S4 was serviced by MRC back in July/Aug last year. Since December I have received two letters from Audi asking me my DSG service is due.

    And it doesn't matter how many one stars you give on the feedback form no one ever phones you about it. Yes I did tick the it's fine to contact me about this box. I've concluded that Audi and VW (both Marshalls dealerships) are just so busy round here there's no incentive to try.

    I managed to book a timed slot for an MOT once when using the official Audi UK portal, my dealer was very annoyed about that but accepted it grudgingly, next time I visited the dealership and forced a timed slot out of them, again it sounded like I was expecting "the world" - I would never ever bother taking my car in to an Audi dealer unless there was some incentive to do so, and reading the Audi UK bumf the incentive was a flexible approach to meeting with customer's needs in a timely manner. This time, when things started to go bad, ie customer asked for what Audi UK offered, I was told to phone them next time - has anyone tried phoning their Audi service dept and getting a response or a promised call back, not me. Anyway, the S and RS service specialist - when I said, "so I'll call next time so that I can get a timed slot" - looked confused, I think that he had forgotten that he had made that statement a few hours earlier.

    What is so difficult about giving a timed slot for an MOT it is, if all goes well, exactly the same as getting a service or brakes changed or tyres changed and these defined tasks all qualify for a timed slot booking with the use of the lounge area, free WiFi and coffee newspapers etc - Audi dealerships, like other car dealerships do not normally exist in town centres, so when you are there, you are there for one reason only.

    Maybe Audi UK needs to brush up on their corporate statements and only offer what is being accepted by their franchised dealerships, that would have stopped this annoyance/missunderstanding that I have had from them, they could also revitalise their brand magazine back into something that almost looked like a professionally written magazine - really get back to basics and maybe even make it look like they are interested in people that like to own an Audi for the cars they are, and not only for the badge and personal attributes that it might give.

    Initially I was going to let this less than perfect experience go, I got the message "tell us how we did" to which I gave a "10" - then they spoilt it by following that up the next day trying to bleed me dry of "goodness" - so I reacted, it passed a few minutes while my wife was food shopping though I suppose. At the time, while the car was in the dealership, it just made me annoyed that I had to turn into Mr Grumpy to get what was on offer, that is not good customer experience.
