A6 c6 3.0tdi, engine warning light on startup but no faults?

[chrissyh_1988]

Hi all,

I have just fixed an issue on my A6 c6 today which was 'coolant fan 1 short to ground', I got under the car and cleaned out the connector and now the fan is spinning happily as it should (I think).

However, I have this pesky engine warning light which comes up when I turn on the ignition. As soon as I start the engine it goes away. I thought it was something to do with the fan fault code, but now I've fixed that and the warning light still comes on when I turn the ignition.

I've gone for a short drive and pulled the codes using carista, and have zero fault codes.

Is that light on ignition normal for these cars? Any other Audi TDi's out there doing a similar behaviour? It's making me think there is still something wrong.

That's what warning lights do ,they come on with ignition ,do checks and go out when engine starts.

Oil light does it.
SRS light does it.

etc etc...

If there are no codes stored then nothing to worry about.

Thanks a lot for the reply! good to know it's normal behaviour...

after a summer of fixing little things here and there my 212,000 mile car finally has zero faults! It's a good feeling :-)
