Fyodor Dostoevsky
Ready to race!
Here’s another problem I’m investigating before my warranty expires (I posted a different problem yesterday).
First some specifics about my mk6 GTI:
- Model Year: 2013
- Second owner
- 17,000 miles (27,500 km)
- Have only used 92 Octane and higher ‘Top Tier’ gas.
The problem:
The engine does not always idle smoothly. For example about half of the times when I’m stopped in traffic, I feel the engine idling rough with ’stumbles’ every few seconds, like a piston failed to fire properly. It typically doesn’t register an rpm change on the tachometer. I simply feel it through the seat. It has done this since I bought the car two years ago.
I figure pre-ignition caused by carbon deposits isn’t the cause because the car is low miles and I have only used ’Top Tier’ gas which is supposed to reduce deposits in the combustion chamber. On the other hand the car burns a fair bit of oil - about 1 quart (litre) per 3,000 miles (5,000 km), so perhaps the oil consumption is causing carbon build up?
Anyhow, my question is:
Do mk6 GTIs normally idle rough?
