Rough/"Misfire" Idle

[K8VXT]

Hi Guys

I am having some problems with a rough misfire sort of idle (Seat Cupra 280 DSG 2014)

So first thing I did was ran codes on the car, 2 errors were stores and but they did not chuck an EML light.

- P006800 MAP / MAF - Throttle Position Correlation
- P227900 Passive/Abiogenesis Intake Air System Leak

After running these I went with the most obvious part to change, the PCV.

Replaced that and however, I am still getting a rough idle.

At this point I'm open to what people suggest, anyone experienced this or know what to do next.?

Thanks,
Kavit

Does your engine wobble on tickova , my 290 does this but when i took it in they said nothings up

Yeah a little with my 280 tbh, weird.

This is issue I'm having is on idle and the engines warm.
No jump in revs just a rough wobble.

Stupid question but where is the MAF it wasn’t on the air intake?

Got the same issue on my 290, misfire on warm idle only, did you get yours fixed?

Unfortunately still a problem, they said to wait until it gives a EML or its obvious where the leak is (trying to find somewhere that does a smoke test)

My suggestion would be for you to plug in an OBD see if there is any stored errors.
