hey, I'm a 2006 a4 2.0T owner and new to this forum.

I just have a few (newbie) questions.

1. What is the proper idle rpm for the 2.0T?
2. How can you tell if you have a failed/failing coil pack?
3. Also, I recently developed a small oil leak (70,000 km), I heard that this is a common problem with the -crankcase ventilation system pressure valve-, is this most likely the case? Does Audi have a solution?


Thank you!

 

There is a revised PCV valve - just have that swapped in (should be under warranty if you're lucky)

Proper idle depends on TEMP - usually 800-900rpm?

If you have a failed coil pack, believe me, you'll know =)

 

Haha, that's good to know.

Thank you for the quick response!

 

Another question (which has nothing to do with idling).

What is the stock boost for the 2.0T (is it a K03?) and what does that increase to when the car is brought to stage 1 (APR or GIAC)

Also, it has been mentioned that Audi's new OEM DV is actually comparable to high end aftermarket ones such as the Forge DV.
Is this true? what is the Audi part number for it and what is the retail price?

Thank you!

 

I am quite interested in this info as well - someone please chime in.

PS - what is a diverter valve anyways?

 

It is a Blow Off Valve..

Thank you!
