    Thanks for your reply c-w , come to think of it its probably more like 5 or 6 seconds , I got carried away and exaggerated a bit, but because there are no fault codes I really need to try something , thanks again .

    I would go with people's suggestions/experience then and try a starter (after trying the temp sensor disconnect which is free!). That's the problem with AUDI is that they rely on fault codes, if there are none then they don't know where to start!

    We had the same problem on my partners mk5 TDI golf, it went in the garage about 4 times until they gave up and swapped the car for a new scirrocco.

    Starter, as they suffer from heatsoak from the gearbox therefore affecting the solenoid operation, proved this on 2 8P's both of which are mine still in use, the new starter makes an unreal difference.

    Thanks , im going to book it in with Audi as they quoted me £312.00 all in plus you get a two year warranty on the part . My local indipendent was only twelve quid cheaper so it makes sense to stick with Audi , I will post the results once ive had it fitted so it might some other poor soul with the same problems , thanks again for all of your input .

    Mate just do it yourself & note the exchange starter is about £130 from my dealer, so save yourself a few hundred as it isnt that hard to do at all tbh & the part is still warrantied for 2 years.

    Hi NHN, as u know I am having the same issue. How easy is it to DIY the starter: what is required & how long does it take.

    I may have a go at this over the weekend if it's easy enough.

    Hope ur well btw mate, was reading your daughter done you proud at the hospital the other day :)

    Easy, just remove your airbox parts which is 10 minutes, then disconnect the connector to the starter, then disconnect the main thick wire with a spanner, use a hex socket to undo the 2 bolts, lift out the back end at an angle then up & out she comes, piece of piss on a bkd 2.0 tdi tbh, make double sure those bolts are done up tight, but dont try to be mr universe and snap them & its gearbox out possibly to replace.

    Yes she did her papa very proud, she's a frigging star mate she really is, she's gonna be a real devil to control I reckon in the next year, she's already moving allot & almost standing, I'm truely shocked.

    Nige have u been taking comedy classes cause u've had me pissing myself this morning, RS£3 thread in particular, lol...

    I am gonna pick up a starter over the weekend and see if that gets the job done. One thing is when cold starting first thing in morning, it sounds like the battery is bad... Sure the tech would have tested this considering starter probs, but will ask for clarification. The car will start near immediately but the first turn of the starter sound like a dead battery. Not seen others mention this in their posts.....

    Anybody who does change the starter please do post results in the thread so we can see if this does the trick.

    One tries ones best dont you know :p

    Check your chassis neg cable as these have a habit of getting rusted below the battery area iirc, some sandpaper & a socket will allleviate that issue, I did mine as it was minimally affected, but made no difference, but has helped others, your 1st turn maybe is maybe waking the starter up a tad & 2nd turn is alive as such, if its a worn out unit then this is more than possibe mate, I mean think about it 5-6yr old car & given these 8P's & reliability at times, not beyond possibility, also battery same situation, stick a varta silver dynamic in, audi can supply as I did mine & was half or more of the price of everyone else, truly shocked me.

    Starting problems when the engine is warm is a well known issue with VAG's TDIs.
    I also have this problem. While searching the web for a fix I found two ways of doing that.
    1) remap; I don't know exactly what is changed
    2) replacing the two contacts of the starter engine. I don't know how they are called in English. They are the two black charcoal things :)

    While replacing them, also take a look at the plastic bush on which the rotor is sliding. It wares off.
    I am going to do this operation in short while.
    Since the starting problem occurs only when the engine is warm, it is clear to me that is a hardware problem. I think the remap is only a temporary solution.

    Two days ago I had to change the battery. It was 5 years old and started to have real problems on cold mornings.
    I've replaced the old battery with a Varta Blue Dynamic with 74Ah and 680A for starting.
    Huge difference. Absolutely no problem when starting the engine. No problem when cold, no more problems when warm.
    So, before remap or changing the brushes of the starting motor, consider changing the battery if it is old.

    Varta Blue is the oem replacement for the car, the Ultra Silver however is a better battery that is used on cars with more tech so I'm told by Varta, of which I have 1.

    My car just wont start when it cold. So I don't know if it will start when warm as I cant get it warm. When I try to start it, just nothing, but then a rapid clicking sound from the engine somewhere. I changed the glow plugs as during a scan this came up as a problem, so changed them all. Car started fine twice, then back to not starting at all.

    Tried re-charging the battery fully, this made no difference, tried a different battery, still the same. Would this be the starter motor then? And is there a guide for changing it? Obviously I cant get the car somewhere to fix it if it wont even start.

    The remap did improve starting slightly on mine. Not as much as my new battery though... Now will start with 2 turns until engine is over 70. Then it takes a few cranks, still a few more than I'd like sometimes. I got a Bosch S4 from eurocarparts said to be the same as a Varta silver dynamic @ £70.

    In the morning it still sounds like the batt is flat though! Weird as new battery... Wonder if my alternator is to blame or if the starter is still to blame - that's the next bit to change for me. It's a ballache as all else is running fine.

    The rapid clicking you hear is the starter solenoid kicking in.

    Sounds likely that the motor is on the blink I'm afraid.

    Sorry - Can't help with the replacement procedure because I've never done it but good luck anyway !

    Cool. At least that gives me something to go on. Cheers. Will try to source one next week and get back on here with the results.

    Doing the Glow plugs was a pretty scary procedure for me to attempt, never opened up an engine that much before on my own. But got it done, will have a go at doing this myself also, but I aint mechanically minded usually. Saying that, I have no choice, because its not like I can take the car anywhere to get it done.

    If you read the thread, my post 48 gives a run down how to swap starter, fairly straight forward.

    Rocker cover of mate, not a hard job, just take time & make sure you put any parts in a bowl or sort & dont rest things on the car or down into the engine compartment they'll go, remember where everything went lol & mostly of all, take your time & patients or something will go wrong.

    Yeah, it was easy enough, but a bit daunting once the rocker cover was off (well for me anyway). I am not mechanically minded at all, and even I managed it, so couldn't possible be that hard.

    As said, don't rest anything near the car, take it all away once removed, else there could be trouble.

    And your as well doing all them at the same time. If one has gone, the rest probably aint far behind, so best just to get them all done at once.

    Hi All,

    I have been having the same issue with my 2004 A3 2.0 tdi. Its random really so its a bit hard to say if its the battery. It only has 32k on the clock and I went to halfords as they check the battery for free and they said it tested fine.. but someone else said that the testing is not too accurate. I was stuck in traffic today and the ride was not very smooth at all so I am starting to think it might be the injectors so might start with some cleaner stuff that you put in the tank when you fill up. I will be a bit pissed if its the injectors that have gone as I mentioned it to audi when I purchased the car in August last year and they said there was nothing wrong with it but it has got worse over time :notme: :tocktock:. So .. injector cleaner.. then battery.. then starter motor.. then injectors.. then skint.

    Cheers


    Mike

    Hi Mike,

    Its both TBH mate.. did a good 50 mile run today and switched her off.. went to start her again and there was a good 4 seconds with the key turn before she fired up. I think its the alternator but to be safe (i cant be caught out at some randon point in the middle of nowhere) I might just replace the bettery and the alternator.

    Forget battery and alternator mate - replace the starter motor. Common fault if you check out the threads - particularly of that age.

    And ignore my mate NHN with the red wine comment - private joke but seems like spot on!

    Trouble is I haven't had any tonight !!!

    hello, im new to this forum. just bought a GOLF MKV 20 tdi and it seems to have this problem when cold it fires straight away but when engine is hot it takes around 3-4 seconds to start, i was thinking to make a service and ask my vw mechanic about this, but seems its a starter motor problem reading this thread!, i was going to have a try first with a better amp battery as the actual is 60amps and was going to replace with a 75amps is the easy way than change a starter motor :) .what you suggest please?
    thanks

    If you think about it, as the car starts first time from cold when it's the heaviest cranking load then it won't be the battery or alternator.!

    I had a similar problem with my starter - changed it only for the problem to still be there. Was forced to buy a new battery as the temps over the christmas period killed it dead - and hasn't had a bother since. Doesn't start instantly, but a 4sec crank when the engine was warm has been reduced to 0.5>1.0sec. Just my tuppence!

    Starters after a while do seem to suffer from the heat generated of the gearbox, known as heat soak, the solenoids & coils seem to not like it after some long periods of usage, but these issues can be a combination of several components, batteries, starters, coolant senders & possibly alternator not charging battery aswell, its one of those suck it & see faults.

    I personally upgraded my battery anyway before the issue arose on mine, but stuck a newer version starter on & it starts immediately everytime, so for others maybe 1 or all of the above.

    How do you upgrade a battery? Just increase ampage rateing?
    Also what newer version starter did you use? Part number?

    Thanks

    I used a better rated one, Varta Silver Ultra Dynamic, standard for A3's are Varta Blue which is the entry level & starter for your car you need to check with audi as they vary, can supply new probably & deliver.
