1.8 and 2.0 tfsi vacuum

[lgooch]

I have a 1.8tfsi (160) which is currently undergoing the oil consumption test with Audi. They tell me that they have modded the PCV and breather arrangement for the chronic oil drinking problem it has. It I have noticed a strange think with it.

When the car is idling if I remove the dipstick it starts to run a little lumpy. If I replace it is idles fine. If I remove the oil filler cap it starts coughing and spluttering and sounds like it wants to stall.

Question is, is this normal on the 1.8 and possibly the 2.0 tfsi.

The car I have is. An 8p black edition

Any feedback appreciated

Yeah perfectly normal.
Just means that the pcv valve is working correctly

Ah that's a relief. Cheers Marshy
