Hi guys,

At present with my MK6 R its been running a bit too rich for my liking. A few people have told me it smelt quite strong whilst traveling behind me but its not producing irregular soot or anything.

The car has an APR Stage 1 Tune, and I have also got the APR Carbino Intake, K&N Pannel Filter and a GFB Diverter Valve Fitted, so nothing too major, and have done nothing else to the car.

I had the tune installed after having the DV and Pannel Filter in, but installed the intake later.

What I am wondering is, does anyone think the other parts could be at fault for this rich running? Or could it be something else entirely like O2 Sensor or such? I've put it back to stock tune at present and it seems to be running fine.

Would love to know some thoughts on this, thanks in advance!
