SOURCE: no acceleration,audi 1.8t,runs like no boost

It's possible that the diverter valve (DV) has failed. The OEM valve has a plastic diaphragm inside and it can crack. If this happens, the car will leak boost air and will lose power as a result. Go to www.audiworld.com, click on Resources, then Tech, and then go to the engine article about replacing/upgrading the diverter valve - it'll show you where it is and how to do it.

SOURCE: warning light on audi a4

This is the indicator for ESP (stability control). If you look on your dash, you'll see a button with, you guessed it, ESP written on it. This allows you to turn your stability control on and off. If your light is on constantly, try pushing the ESP button. If it flashes on and off (ie during hard driving) this simply means it is working.

SOURCE: Audi A4 need to replace rear brake light on audi a4

Inside the boot is a plastic cap embeded in the boot liner. Remove the cap to reveal a screw. Undo the screw and the whole rear light cluster will come away in a sideways and not rearward direction to reveal all of the bulbs. Hope this helps.

The dealer has to "reflash" your 02 sensor light. On some Audi's, the dealer has to reset the O2 code first and if it comes on again, then they will need to replace the cat convertors.

Mk1 A4 ABS warning light


I have a 2000 Audi A4 and the break wear sensor warning light come on for me too. It does not flash and is orange in color. I have asked the Audi dealer twice about it and they told me it's because the previous owner put aftermarket break pads on it, thus messing up the sensors. I don't know about the ABS warning and other than that I wish you luck on it.
