Air not blowing out dash vents

Fan not working. Either a fuse has blown and the fan is not getting power...or the fan is dead. Check fuse, check for power at the connection to the fan, then replace fan if there is power.

The red ambient lighting on my D3 Audi A8 MMI control panel has gone off. All the buttons use to light up with light on - now nothing?

You failed to mention which control panel and year. Have the codes read for that panel.

Hi have a Audi a8 rear n/s brake led light can it be replaced or will have to replace the hole circuit board.

Audi and other suppliers only sell complete lights. Try you luck at a scarpyard or ebay. These lights are expensive. If you have facelift version is a sealed unit. These is even more expencive. Pre facelift is not sealed, easy to fix. Often the LED`s burn out. These can be replaced if you feel safe with a soldering iron. Check this out if you have pre facelift: https://www.audiworld.com/forums/a8-s8-d3-platform-discussion-60/d3-a8-led-tail-light-diode-repair-2901254/ Posted on Sep 09, 2019

I have a 2005 Audi A8L. Last week I got something out of the boot and then closed the lid, but instead of hearing the reassuring sound of the boot lid locking, there was none and the boot lid remained

Hi Barry,

Sometimes, the locking mechanism closes while the lid remains open. Simply press your unlocking button on your fob, or in the vehicle. Then try to close the lid again.

Hi, I recently had gearbox sump gasket replaced along with filter and oil. A8 4.2 now developed clunk from 1-2 & 2-1 up and down gears. Otherwise very smooth as normal. Appreciate advice ..

It would help to know year and model (and therefore gearbox model) of your A8.
The 5HP24A in the D2 series (circa 1997 to 2002/3) has several issues and are commonly regarded as "fragile".

I have never experienced this when changing my fluid (I have a 2001 S8), but I have read reports that some filters have pick up tubes that are too long and need to be trimmed back or the gearbox can suffer from fluid starvation, particularly when pushed.
Also check that the gearbox sump has not suffered from any impacts. The fluid pick up is roughly central to the sump at the deepest area (both the oil drain and fill plugs are higher).

Was the work performed by an Audi or ZF specialist? There is a particular fill procedure which must be followed.


The gearbox can also suffer from pressure spikes (particularly in early models) which can damage the Clutch A basket, which is used for gears 1-3. However any damage here will result in immediate limp mode (all gears lit up on the DIS screen and gearbox locked in 4th gear).
