Hi guys new here just signed up I have seen some good stuff on here and I need some help from the gurus
I have a 2008 a4 b8 3.0 tdi quattro and the turbo actuator is playing up.
No loss of power still opens and closes from drive to neutral and reverse to neutral (I have the stronic box) no warning lights on the dash nothing drives lovely and smooth and nothing is at fault until I come to a stop at a set of lights or when I stop to engage reverse. It's almost as if its hunting to find the idle rev of about 800rpm. But at a set of lights sitting in drive it's lurching all over the place and it does it in park too. 1200 rpm down to about 400 then back up and down again and I can see the actuator under the bonnet moving back and forth. Then after a while it settles and stops and just ticks over nicely. It's an intermittent fault but it happens every day but if my missus drives for 2 hours a day it will do it for about 15 mins. Audi want 2400 for a new turbo but I explained the turbo is fine doesn't lose power or smoke or anything...... Any ideas guys I'm stumped.. Thanks in advance
