SOURCE: water damaged 99 Audi A6 Avant

On right hand drive vehicles there is a 'convenience' ECU under the front passenger side carpet (I think it swaps and is under the right hand side in a left hand drive) This ECU operates and controls all the systems you have described, they suffer water damage very easily. This will be the cause of your problems and unfortunately will need to be replaced and coded. The ECU was put in this place to keep it well out of the way of any contamination such as water, then the cars ended up leaking water straight on to it! The carpet in the front can be lifted up from the edge by the door with a few trims removed. You probably had quite a lot of water in there because water runs to the back of the car, by the time its visible in the back a lot of water has entered. Let me know if you want anymore imformation.

SOURCE: how do i change time on clock on 2005 audi a6 quattro s line

I think I can help you. I just did this on mine yesterday because my clock runs a few minutes fast each month. It was somewhere bizarre - sorry I'm not near the car to be more clear. I think I picked Sound, Settings and for some odd reason, it was there, rather than in Car, Settings. NOOO - it was in Tuning - click the AM/FM button, then Settings. I've only had it for a few months, but you'd think I'd have that one figured out due to re-setting it.

SOURCE: Audi A6 2005 LH Rear Turn Signal & Brake Light Failure

I had a problem with rear left side signal brake and reversing lamps not working on my 2007 A6 2.L Tdi SE.( Intermittent fault for 2 months)
I think I have identified the problem.
The seal between the Lens and the bulb plate had allowed moisture into the lamp.
During sunny days the water evaporates and enters the multi pin connector at the rear of the lamp.
On close examination of the connector I noticed minor discolouring of the ground ( Heavy Brown Wire connector Causing intermitting lamp failure )
SOLUTION
I expelled all moisture from the lamp and multi-pin connector.
I removed the neoprene seal from the lamp and refitted it good side up
I cleaned the ground pin on the connector with 600 grade paper and contact cleaner
I put a slight twist in this pin with long nose pliers so as to get better connection.
Lamp is working fine since.
Changing the bulb plate may also work
Great care must be taken when changing bulbs or this problem will reoccur

SOURCE: Audi A6 3.0 tdi Quattro 2005, glow plug light comes on, limp mode

16619 -Engine boost condition - Limit not reached. Check intake hoses/ connections for leaks. Check Turbo charger waste gate regulating valve/ waste gate working correctly. Must move freely when accelerating, won't achieve full boost if waste gate sticking open. Check Turbo impeller turning freely, oil feed pipe for turbo can get blocked causing impeller to seize. Engine compact, not easy to access these components.

Audi a6 quattro 2.8 coolant leak


First of all, are you sure it is a coolant leak and not the natural draining of the Air Con., a leak on piping to or from the washers, condensation from the exhaust etc.?
Does the coolant level drop significantly and if so, how much and over what period?
Can you collect in a tray the liquid that is leaking? What does it look and smell like and what colour is it?
Does it leak with the air con disconnected?
Does the heater work properly?
When you say that it is leaking 'right under the middle', I presume you mean the middle of the car. If you park over a newspaper, where does the drip end up (which might not necessarily be immediately below the leak)?

Check your heater core. I had a 98 saturn that did the same thing and didnt realize what it was until my heater didnt seem to be as hot. Should be under the dash most likely toward passenger side. Look in a repair book to be sure.

What could be the causes of a coolant leak or how to diagnose a coolant and oil leak on a Audi 2002 A6?


quick method is to park the car overnight, mark the wheel locations with chalk. after you have moved the car have a look at the pavement. that will give you an idea or what location the fluids are leaking from. if the water pump is failing it will start leaking water from a small "weep" hole on the front.
check your oil as well and let me know what colour it is as well as the colour of the exhaust smoke.
