I have the 2011 octy vrs. Recently it started hunting to 1.2k and sometimes staying at 1.2k revs at idle. Mechanics just replaced a supposed leaking PCV hose, but it't still happening. Does anyone have an idea what could be causing it?

It would be a good idea to state what engine you have.

 

Some car history would also be a good idea, mileage, servicing how long the problem has occured, when it first appeared. How long have you owned the car.

 

Kev.

 

Edit:-

Also forgot to say - Have you carried out any diagnostics such as with VCDS.

I have the 2.0 TSI. Mileage is high-ish at 95k miles, but the engine was perfect before. Also had timing chain done previously. Ever since my turbo replacement in August I’ve noticed that the hunting happened but normally I ignored it because it happened once and then disappeared for a good 6 weeks or so each time. This time it’s persistent though. I don’t think it had a VCDS done, but I did give it to a garage that was “specialised” with vw/skods/seat diagnostics.
