'06 V50 T5 Code PO100 & PO036

Post by jnitschke123 »

Hey folks,

I just bought a 2006 V50 T5 AWD 6 speed, and i'm super stoked to own this car! I'm currently working though solving all the issues it has, and one of them is a constant CEL.

The car has codes PO100 and PO036.

I noticed that the car has a wonky idle, and shudders while revving after start up sometimes. This clears up after letting it "do its thing" for about 15 seconds.

So far, I have cleaned the MAF and reset the CEL, to no avail. The codes came back (at the exact same time) and the car still has an intermittent wonky idle / shudder problem.

Any leads would be greatly appreciated! :mrgreen:

Cheers,
Joey
