So i have been driving my audi for a while now and just today my car started loosing power like it would stagger from idle -3k rpms then would rev up fine. then as i was taking the girlfriend home my car was shaking it was idling real rough and i shut off the car opened the hood and the turbo had a slight glow to it. does this mean the turbo's going out? BTW i havent checked the CEL i gotta take it to a shop to get the codes, thanks

 

Misfires. Read out the DTCs.

 

Is that what low rpm bucking or bogging ushally means? misfires? I seem to get the same thing everyonce and a while, it almost seems as if something along the driveline is 'slipping' and cant catch up.

 

plugged Cat....makin the turbo heat up too hot, possibly ruined plugs too...check DTC first....but pull the plugs and check them too

 

yea it definatly sounds like missfires. i just had the same problem in my 2.8, had to get the plugs replaced, since then its been running fine.
