A7 3lt TDI Quattro

Hi, just joined being an Audi fan and hoping for feedback. My stunning A7 has developed an intermittent rough idle which settles once driven. No lights on, diagnosed with no finding. OmG what's wrong with it.

Allan.

You have given precious little useful information, so how about telling us: mileage, service history, length of ownership, details of any investigation of the problem and by whom, circumstances when the problem occurs such as hot or cold etc.

Ok it's 80k miles, full services history, I've owned for 12 months. Problem been about 3 weeks, only when starting mainly cold starts. Rough idle, slowly goes then drives fine. Wondering if I've caused by putting fuel cleaner/injector cleaning in tank and direct into inlet.

I'd recommend you get a diagnostic check to see if any fault codes flag up. It could be an issue with the maf sensor, injector, injector seal, cam position sensor.

Had full Diagnostic which gave no flags. Will reset MAF see if helps, started fine this morning. Next step chop in and get a lada
