My Audi appears like its going to stall at low revs but never does!?!!?

Asked by Aug 11, 2015 at 02:55 PM about the 2008 Audi A6

Question type: Maintenance & Repair

My Audi A6 automatic has recently had the
EGR valve and MAF sensor changed. Since
it has when the car is at low revs (when
using the throttle) it judders like it is going
to stall. It never has and this doesn't happen
when idle or cruising. This can be at 10, 30
or 50 mph

How clean is the throttle body? IAC sensor could be plugged. Get some Brake cleaner and get rid of the carbon buildup!

Hi. Throttle body is clean already tried that. The original fault was EGR so stripped and clean it all. Fault remained so blanked off and car still wouldn't run above 20mph. Disconnected AMF and it ran so had both components changed. That's how I arrived at the scenario

Do you have a Service Light on? How is your fuel pressure?

No service light. How can I check the fuel pressure?

You'll have to get a fuel pressure testing kit. Here's a video to help you get an idea. https://www.youtube.com/watch?v=76aF67G34nQ

I need more Info!!!! Need to erase all faults and drive it around for 1 hour and read and reply codes. Also is this a CVT or Quattro?

by the way I won't even pay more attention to the MAF or EGR this is just taking you to a opposite direction. Erase , read and reply . Ariel Krankenwagen European car specialist

I really think you have worn out cvt clutches and only show in low RPM while running just for the fact that your RPM's are to low to build enough pressure to engage clutches and that's when the judders or bucking happens after that everything is good and even in you get on the highway and cruise around 60 mph and just apply your gas it happens.

Hi Krankenwagen. Thanks for the response. Are these replaceable parts or is it a complete new clutch?

Oh and it's a 2.0 litre CVT

Where are you from? It sound like you are not in USA since we don't

have 2008 a6 with 2.0 cyl turbo down here

The clutch replacement it need to be done by a transmission shop and the dealer sales the clutch pack kit. In USA I think there is a legal lawsuit and audi is recalling some cvt's for repairs
