Check engine light disappeared ?

Hi all, I took my 2010 stock gti to the dealership to figure out a check engine light I had for few months. Car had 98k miles with coils replaced. They said it was a pcv valve fault and the dreaded rear main seal was leaking---which I was quoted for $1200 repair.
I did a the pcv replacement on my own last week. And I noticed today the check engine light is off today after driving it for a week. I wonder if my rear main seal was OK all along. I don't see any leaking oil under the car.

sometimes if it is not a persistent fault, the CEL will "clear" itself. it will still register as having been there until it is actually cleared from the ECU. The leak could be a slow leak, something to keep tabs on for the time being? Also make sure you check your belly pan for oil regularly...

(belly pan aka skid plate aka skid pan aka....)

this is a plastic "plate" of plastic that typically is held in place by screws located under the engine bay. prevents road debris from wreaking havoc on your engine. Aftermarket ones are available if you so please, typically make of aluminum.

to check this, while the car is off and in park, look/reach underneath and touch the plastic you see under the engine bay. if you have jack stands, then you can get a better look that way.
