Om my 2001 Audi A4 Avant T1.8, I have minimal heat and no indication on my temp gauge. I have changed the thermostat and it made no difference. Does anyone have any other suggestions?

hey mate
going through similar problem myself right now. 1997 A4 1.8 (same vintage as yours I think)

No heat from vents (luke warm at best) - temp gauge never moves.
I've also been getting really poor fuel economy - I think it is linked to this, as the EMU thinks the engine is constantly cold and changes the air/fuel ratio (like having the choke out when driving).

Q: Does your radiator fan come on when you start your engine from cold? It shouldn't come on until the engine is warmed up. If so your problem could be to do with the fan control unit, or the viscous assembly of the rotor itself. Both can be replaced as one modular unit.

I would be curious to hear what solution you came to as I am troubleshooting this myself at the moment.

Hi need to change rear brake light on my 2002 audi a4

After removing screw,you need to prise unit off
Start from inside of unit untill it moves,then push to out side of car to release
The unit will be tight,as it probably has not been removed
The ideal tool to remove is a plastic trim removal tool
A screwdriver will do the job
Refitting,locate slots on out side of car,and push firmly in,replace screw

Audi A4 2002 Low beams & Right front turn signal stopped working

For Audi A4 the fuse box is located on the left side of dashboard behind a plastic cover (for left hand steering wheel vehicle). On inner face of the plastic cover you will find the fuse diagram.
First fuse on first row from left upper corner is Fuse Nr.20 = F20 (15A) - RH headlamp low beam, headlamp adjustment.
First fuse on second row from left upper corner is Fuse Nr.21 = F21 (15A) - LH headlamp low beam, headlamp adjustment.
