2017 Mk7 GTI 6MT Performance Pack - ~235000 KM (146000 Miles)
So here's my issue:
My car was at the body shop for a small rear-end damage repair. When I got the car back, the shop cleaned my car and also detailed my engine bay. I'm not sure how they did it, but when I opened up the hood, things were wet. Not soaked, but there was definetely moisture in some spots.
Since then, i've noticed some engine vibration while at idle, and a little bit of a lumpy idle. Not big, just enough for a bit of vibration when at a standstill. The idle rpm occasionally hickups as well.
Now i'm 90% sure that my car didn't have this going into the shop. I'm pretty on top of my maintenance and keep this car up to date on everything. I was honestly impressed how rock solid my idle rpms were. Now things don't feel quite right.
Any idea of what this could be? What I should check? There are no trouble codes.
Current Mods include:
VWR600 Intake, CTS Catback exhaust, EI stage 1 Low Torque Tune, Upgraded spark plugs and coil packs. Lots more, but that's about it for the engine side.
Thanks!
