My speculation from the phrase "running out of road" is that the braking is harsh enough to trigger the ABS system. The rapid sequence of brake & release pulses can cause vibration.

Many people have. Look through the forum history to find various suggestions for the cause and possible solutions.

Check the battery tray area and pollen filter housing to see if that's letting water in.

Sort of. ABS prevents the wheels locking up which means the car can still be steered. (A tyre that is sliding on the road can not provide traction, braking or steering.) It does not make the brakes more effective. The penalty for ABS is the vibration, which can be quite violent, felt throughout the car as the brakes are rapidly applied and released. If you have a partly seized caliper be grateful for ABS for preventing the car going into a spin. ABS in those circumstances is not unneeded.

Hi Gareth, only spent a couple of hours so far on the first one but before and after shows the result so far. I'll be working on both sides tomorrow providing the rain keeps off.

Ah, that makes sense.

Good luck! Mine has been recovered to Cheshire Oaks Audi today. Let the fun times begin!

Truthfully I do not know. It's what I witnessed when working at VW. Also it's the same on my wife's Jag. I think passenger seat gets moved more as different passengers. Whereas the driver side doesn't move as much.

I’ve now removed the ‘Mark as Solved’, and invite Rickie to give us more detail about the when’s and how’s of this. Kind regards, Gareth.

Hi Gareth, I'll be trying the wet flatting today, nothing to lose and could save a load of money. Thanks again for the helpful advice.

Check under-seat connections - BUT DO NOT REMOVE THEM. ( apologies for caps). Just get some contact cleaner and give them a god spray and a wiggle. Perhaps you could let us know how you get on Alex. Kind regards, Gareth.

Thanks for the advice Gareth, I've already tried the T Cut method but no joy, I'll certainly try registering with Partsfinder and similar. I'll let you know if i'm successful.

Just my 2 pence worth, I know I wouldn't be risking it. I appreciate my A6 is older but it's interval is every 8 years. I certainly wouldn't go over that. So if it were mine I'd stick to 5 years. Also the £633 tive been quoted is reasonable in my opinion

This is illogical to me, and I believe it is engineeringly unsafe, and wouldn’t be for me. While noting David’s - Itspointless- comments, I’m afraid I would have to counter the view that …’so age isn’t an issue’. It can, and is indeed an issue. The ongoing serviceability of a completely unstressed belt stored in a box for say 5 years, cannot be compared with a fitted belt which has been subjected to hundreds of highly stressed stop/ starts every week, sometimes in sub zero temperatures. If (in caps) Audi U.K. and I then guess Audi Global ( rather than a dealer) are saying there is now only a mileage limit, then how many of us doing short but regular low mileage trips around town etc. would be prepared to chance our engines ,when running on a 20 + year vehicle? Darren’s dealer’s phone call is interesting, and I’m not sure whether it was an out-of-the-blue call, or it was as a result of Darren having made a prior enquiry -? Audi economics?? Profit is made by the Audi dealer when fitting new belts and VAG make a profit on resale of the belt kits manufactured for them. However, if a belt fails, the potential for revenue is considerably higher where the vehicle is declared beyond economical repair and has to be replaced, or a very expensive engine replacement arranged - potential for far more profit! Now the Audi Economics makes logical sense - to Audi!! Sorry folks but it still doesn’t to my pocket. Additional point to consider - renewing the auxiliary belt -? I can see this timing belt scenario becoming an ‘inherited issue’ for buyers in the future, as the baby is passed on as the purchaser’s responsibility. Kind regards, Gareth.
