Hey guys, I got a 17 GTI and been having some issue for a while. I've experienced the car throwing a EPC light (NO CEL) when driving normal and OBD shows Injector monitoring in cylinder one& OBD shows that it fixes it self. I would do a data log to show you guys but OBD11 on apple doesn't record, only shows live data. I heard about the dongle OBD2 that records logs for you just haven't bought it.Today I got the EPC light 3 times. 1st time got a misfire in cylinders1 & 2 on top of the injector code in cylinder 1. 2nd time it was just cylinder 1 injector, and 3rd time same thing. Happens when I'm driving normal cruising in the higher gears. Car been hitting limp mode with the injector problem for quite a bit, but today it happened 3 times. I got pops and bangs that go off every time I let off throttle and downshift, and I downshift a lot. Im gonna remove the pops&bangs cause atm its a little aggressive. I have been tied up working a 9-6 job M-F when everything is literally opened those days and hours. I still daily the car and it got 56k miles. Oil changes serviced at 5k intervals. I did spark plugs to replace the ones that had about 10-15k miles with new ones, but still running the same coils thats on around 15k miles. I am hoping if I change the coils to new OEM ones the misfires with get fixed (hopefully). When I did replace my spark plugs I had oil on two plugs but wasn't sure which cyclinder it was since I didn't do it. For the injector I am not sure at all. I am hesitant on buying the "Fuel Injector Service Kit" from UroTuning for the price because I am guessing Injector one is bad. One thing that raised an eyebrow for me today when I parked up on the driveway and started to press the clutch in and out and I saw the RPMS bounce as I was clutching in & out, then it stopped shit had me automatically thinking about the crankshaft moving. It looked like I was blimping the throttle slightly.
You guys are all pros and well knowledge with this platform, I want to hear your opinions on the Injector in cylinder 1 and the RPMS bouncing when clutching in & out (only happened once today & went away, never had this happen.) One mechanic told me the engine is possible bad, & to me shit still drives like a champ. Idles on cold starts smoothly so it can't be carbon build up. Maybe do a carbon cleaning and clean injectors if thats possible?
