Hey up.

Just back from Thailand and an issue I was having with my rear left has come on again. Lost 10psi whilst it's been sat!

Happened few months back. Forced up onto a curb and took a chunk out of tyre (but it remained). It's sporadic though. Can pump upto 36 and the tyre monitor will sound to say it's not dropped at all. Then other times, it will go off and it's dropped about 2 psi or so. Then, it can simply not go off whatsoever.

Was going to change to winters in October and forking out for a good summer for a month is frustrating. Can they simply be patched or repaired temporarily?

Cheers all.

To be honest I wouldn't be taking the chance if I knew i'd done some damage to the tyre. Whilst it may be a slow puncture a low speeds who's to say it won't suddenly develop into a blow-out at high speeds?

I'd definitely take it in to get looked at but if it's taken a chunk out of the rubber then they would most likely recommend changing it.

Always better to be safe than sorry.

Is there a chance you've got a nail in it somewhere? Had a similar slow puncture on my wife's car recently. I couldn't see anything but the garage found it - and of course it was in a non-repairable place.

Don't mess around with tyres. Get them fixed or replaced, and don't buy cheap. I'm sure I don't have to tell you that though!

Yeah it's booked in.

Cheers for the responses. I have, however, gone cheap. One simple reason, I'm changing to cross climates or winters from October. Not spending £150+ on a tyre for one month. I will be smart about it though and adjust my driving accordingly. I'm away for half the month anyway.

Brings out another question though, can't find Michelin Cross Climates for the S4 anywhere!! Only 19" they do is for SUVs. The measurements don't fit I think. I'd really like to get those tyres from all the reviews I've seen/watched.

Soooooooo...

I have yet, another, strange slow puncture. Again on the passenger side but this time, the 'front' tyre. This is becoming rather an odd situation for me. I've tried to identify large pot holes or driving habits to no avail. And even if there was, it would be unlikely that I'd get 'two' slow punctures and not something else more immediate.

You guys got any ideas? Stock, 19" Hankooks.

You haven’t hit a pothole and ended up with cracked alloys? Over inflate the tyre and cover the whole wheel and tyre in soapy water and see if you can see bubbles anywhere, certainly odd.

Interesting thoughts there.

Would it not be proverbially ******* in the wind doing that? I mean...with a bicycle inner tube, it's easy to see but with the indentations and such a large tyre? Ya know? I'd thought about same damage from one incident too but...wouldn't I have seen tyre issues on both tyres within the a similar time frame?

I had issues with the rear left for about 2-3 months. So, June to August. Then I replaced. I've only just started having issues with the front left. Both slow punctures. COULD constant over inflation or inflating to 'full load' PSI cause an issue over time? Because I have dropped the ball there I'll admit. I misread the inflation chart and I've had them at 41 (front) and 36 rear. But even then, it's in the tolerances for it.

I've dropped the pressures to 36 and 33 respectively. See what happens. But maybe book into Audi for them to physically check for a puncture and rim damage? It's just something I've never seen before. On one wheel I could understand. But not two.

A hairline crack is certainly possible, it may close/open depending on where it is when the car is parked hence the irregularity.
If it’s so slow then I can see the futile soap option.
Are the inner cores of the valves secure?
I checked my pressures the other day all were around 5psi down but being all the same I guess it’s natural loss

I’m going to check mine later, I have them at 41/36 is that not right?

Well it says it is but there's an Audi chart showing different apparently. I'll try find it. It's on here actually.

Not of help to you, but in my first month of ownership I've had a screw in one rear tyre, and a nail in the other. Have just been over my whole gravel drive with a metal detector to see if there are any more, but nothing. Guess it's just super bad luck, but starting to wish I took the option of tyre and wheel insurance :/

Yeah I think I read about this mate. Recently. That's bad luck. These things could just be that. Law of averages on overtime though.

Screw necessitated a new tyre - £180 for the privilege. I've yet to get the nail sorted - only discovered it on Friday. Going to try and see if it can be repaired tomorrow - its about an inch medial to the side wall, so here's hoping. The missus also has a puncture on her Galaxy, so that makes a total of 3 punctures in 3 weeks. We've recently had a big issue in my village with the landowner behind my property (farmland) trying to get a development of 80+ houses approved; I led the opposition, which was successful, and the application was refused on appeal also 3 weeks ago. Call me paranoid, but I thought someone might have decided to "congratulate" my successful leading of the opposition with a liberal sprinkling of sharp objects on my drive - but that doesn't seem to be the case. Still considering CCTV installation though!

Ugh. Tell me about it. If there's one thing you can rely on, it's the evil of man. I'd like to get a CCTV install so let me know how that pans out. I'm booking the car in tomorrow for them to a) see if there is indeed a puncture and b) see if there's any wheel damage causing these.

oh whoopee - the nail is "in the wrong place", so despite being about an inch in from the sidewall, apparently it is "on the turn", so need another new tyre. argh!! I should buy shares in Continental.

Typical. I'm shelling out £750 for winters soon so I feel your pain. Good deal though.

Car booked in tomorrow morning. Running a slightly lower PSI hasn't solved anything so I'm thinking there could be alloy damage or just really strange bad luck on both tyres.

Haha. Certainly wasn't comparing to yours. I meant more that it's strange is all. Be pretty annoyed if it's a new wheel required as the car should be able take these things. It's not like I've went off road or even hit a huge pothole.

My spidy senses are telling me it's one of these issues. Didn't realise it was that common:

hairline fracture in alloy causing slow puncture

Here is my door plate showing pressures? I must admit 41 sounds high but if I run them at 36 the steering feels woolly?

Hopefully your issue is tyre related, if not is it not worth a warranty claim, if there is no tyre damage then the rims shouldn’t be cracked?

100% with you on this. The steering felt awful at 36. I've pumped up to 40. Probably 28 in the ****** morning haha. I agree mate, the alloys should not be cracking. They're not silly aftermarket rims. That's what I'll be pushing for with Audi likely to push back I reckon.

They will certainly push back, I’ve found them terrible so far at responding to issues so far.

Not sure if it will work with tyres on, maybe tapping the wheels with a small hammer and listen to the noise? They should all sound the same, it’s what they do on train wheels ... just a thought.

It's only the morning, my booking. I'll see what they say. Will they have the tools to scrape out any gunk/frag and re-seal inside if necessary? Or would I have been better off going to ATS or something?

Is this from those inflation tins? Not sure how it is cleaned out tbh?, I guess pressure washing should do it?

I wouldn’t go to a third party as that gives them ammo to reject any claim.

I'd agree. At the very least, you should insist on Audi deflating and reseating the tyres for starters, though with a chunk out of one......well you know what'll happen there.

Lets face it, having a flawed wheel from new is pretty remote, let alone 2 of them. So they've either got a dodgy fit somehow, and to be honest, that's doubtful, or there is indeed something small in the tyre(s) that hasn't been found yet, combined with maybe a sporadic leak from the one with a bit missing.

With the curb banging, is there any visible wheel damage that could indicate a crack?

Must be annoying though.

The curbing was minimal damage wheel wise. The tyre wall extensions helped there. And since replacing that tyre, I've had no issues.

Currently on the front passenger wheel, there is nothing to indicate any damage exterior wise. To crack the wheel it would have to be something I'd notice. Ya know? I think there's something loose in the wheel. That's my guess.

Just odd that they're both the passenger side and both were/are very slow punctures. Some good input there mate, appreciate it.

on my old B8 avant i had a tyre that kept losing pressure and got audi to have a look when it was in for a service. initial inspection couldn't find anything so they ended up taking the tyre complete off the rim and the technician ran his hands on the inside of the tyre and found a very small thorn that had gone through. you could not see if from the outside. so suggest that to them.

that is what they told me. think they spent about 30 mins checking the tyre to find it as it lose pressure when it was with them. so they knew something was not right... as it took so long to find the issue they did the repair for free as well. :)

Ooft. I'm hoping it's something as small and basic as that mate. That was good of them. 3 of mine are just on legal tread. Didn't want to fit the winters until I knew for a fact that this wasn't just coincidence.

Just to ask, if I may, what sort of mileage have you had out of them, mine are down to around 4mm after 6000 miles, I must kerb (scuse pun) my use of the throttle on slip roads.

16k miles mate. Usual camber issues though. Not the whole tyre down on tread.

if i had £65k i would for for the RS6 but on finance the RS6 would cost so much more, well on a PCP as the GFV would be alot lower then the RS5.. must start playing the lottery again...

Yeah you're right. But there's competitive PCP Finance out there. On a side note, I'll be getting into bother in a bit. Didn't expect the Airbag fix so they're gonna flash the ECU and find the valve unplug. Ugh. This could be quite a day.
