Audi a6 Dashboard problem in cold weather

I am trying to solve a electrical problem on my A6 which started occuring this winter.
When I start the car first thing in the morning, all the gauges in the dashboard and all the lights (not only the dashbord, but also the lights on my climate control, my stereo system ...) go off for a moment, and then go on again. This situation repeats every few seconds and lasts until the temperature in the car increases. Also, on the dashboard display I can see the temperature and it says that the outside temperature is +37.0 degrees, although the outside temperature is below 0 degrees. This problem also disappeares when the inside temperature rises.
So, I have two problems and they have one incommon thing. Inside temperature :)
I would appreciate any suggestion or a idea, not to mention an answer that can solve my problem
Thank you in advance

    The problem is somewhere in the dashboard. It's well known by some people keeping this valuable information. It might be on a 'Motorola' faulty chip inside the unit, but no more information yet. I still hope not having to spend hundreds for such little thing...

  • Hello. I posted this thread a while ago and completely forgot about it. I managed to find a man about a year ago who replaced the Motorola you are talking about. After that, everything went back to normal. He did the job for about 100 euros. Their website is There is not much on it, but you can contact them and try to solve your problem

Sounds like a faulty outside temp sensor. This is located behind the lower front grill on the rad support. This sensor is likely causing your both issues as the voltage drop or resistance is not in the range the ecu expects. You can check they will help to clairfy swapping the sesnor if you feel like getting your hands dirty.

The biggest problem with intermittent problems is getting them to occur.It seems that your trouble is sticking around,and maybe you need to just give in and have it flat-bedded to an Audi shop(hopefully the ride on the truck will be gentle enough that the trouble won't clear itself).

Coolent system fault symbol Audi A6

1998 Audi A6 2.8

It could be that the thermostat is stuck in the open position thus providing maximum coolant flow through the engine when the engine is still cold, ie from a cold start. (The thermo should close when the engine is stopped and cold and it opens up once the coolant temp increases and the engine has been running for a few minutes.) Once the engine is hot maximum coolant flow between engine and radiator is normal.

Do you also find that your heater takes a while to provide warm air to the cabin in winter when you notice this condition?

If you do not know when the thermostat was last changed then I would suggest you change it. ( If it malfunctions and sticks in the closed position you will really have a problem). The radiator/engine coolant could no doubt do with a flush and change in any event as it should be done every 2 years. If you don't know when it was last done - do it. Cooling systems tend to be a neglected part of essential vehicle maintenance.
