Hi guys,
After I replaced VGC gasket/cam plugs/SAI tubes/PCV valve/CV boot, finally my 2003 A8 is in good condition without oil leak smells.
Now still got 2 small issues.
1. Almost no air comes out from rear AC vent on back of center console. If fan speed is 10, I can still feel a little bit of air blows out otherwise almost no air. Wondering is there could be separate fuse to control the vent door somewhere?
2. coolant level alarm comes time to time, (I do have a out-dated coolant temp sensor which I suppose has nothing to do with this?) do you guys know if it's common issue with coolant level sensor? I think it might be on bottom of the reservoir?
Cheers

You are in the D3 forum (A8 2004-2009) You need to post to the D2 forum.

Thanks Richard, it's a D3, late 2003 built and a 2004 model.
In Australia, it's imported since 2003. And I believe Audi has started building the D3 since late 2002 probably.

Ahh...makes sense now.

If it were mine, I would check the various air flaps using a VCDS.

I would replace the coolant tank. That should get rid of the low coolant warnings.

Thanks for the suggestion. Much appreciated.
