I've had a brand new Bosch S4 battery fail within 2 weeks of being on a car. It always showed over 12.5v. It was the cranking amps it was way down on. Was rated at 740, but only producing 350. The test was carried out by the RAC and the battery was swiftly replaced under warranty.
I had my exhaust boxes deleted on my 2.5 v6. It sounded great. Wasn't too loud as the pre-cst and cats were still in situ, but the v6 noise along with the turbo burble made it turn heads in the street.
A place in Darlington removed the boxes and welded in matching sized stainless pipe. As for...
A lot of cars have sensors on both sides of the front. Probably due to as the car ages, calipers stick and wears one side down more than the other, so more of a precautionary thing at a guess.
All my Audis have had a sensor plug on both front sides. Even my 2008 Ford Focus had one on each side.
It's an anti-dazzle glass. You must have the anti-dazzle rear view mirror in the car, as its connected to that. Or at least it is on the A8 models.
We have an S8 with the same style of glass. Again, the price is extortionate for a wing mirror glass, so I replaced it with a tinted blue heated...
Where are you based? There is a usrrs VCDS map, message people local to you and they will help out.
Get the subsystems read before removing the gearbox tcu.
Does sound like water ingress somewhere. Which gearbox type do you have? IIRC, one was susceptible to coolant leaking onto the gearbox...
Check the air mass meter. Made a difference on my 2.5 quattro.
Cleaning the turbo made a difference also.
I did take pics and posted them on a guide on here. Not a difficult job but one that is very worth while doing.
I'm replacing the upper control arms on AN S8 D2. One side has never been off in 19 years, and one side has.
The passenger side, which hasn't been off, had 2 little spacers which sit between the top plate and the bodywork. These slide over the studs, 2 out of 5 in total.
Sounds like you have factory xenons. They're self levelling, hence no adjuster switch. When turning on, they should raise and lower before settling at the correct level.
Two sensors operate this, three is one on the front, usually nearside, and one on the rear, usually offside. These little...
Can you not hear the lift pump priming? VCDS can cycle the lift pump for 30 seconds a time to help prime the fuel system.
But if you can't hear the pump, sounds likely its failed.
The tandem pump will work fine without lift pump, if the system remains primed.
My 1.9 tdi had a leak on the...
