Tiguan Injectors replaced

Miles 48639

Tiguan is getting “21086 – Injector: Cylinder 2”. Engine would stumble a little and then EPC would be enabled. Once the car was cycled it would be fine for a few days until we had the issue again. I tried two tanks of Injector cleaner to see if it was carbon buildup but sadly didnt resolve the issue.

Ended up taking it to my local shop, they tried to reproduce it but were not able to. I gave them the go ahead to just replace all 4 injectors.

We noticed an immediate difference when we got the Tiguan back. Engine was way smoother and its been a few hundred miles without issue.
