Hey guys,
I have a 2017 GTI S (6speed) I purchased January 2020 with 12k miles off a lease. Today I am at 53k miles and love the car since I bought it. At about 20k miles I installed a CTS DP and left the stock ECU until 40k. I am tuned stage 1 (supposed to b stage2, couldn't afford it atm) so I still get a CEL for the DP that comes on every once in a while. 4 months ago I purchased an OBD11 and now I am able to see what codes I get every time I get a CEL. Ever since I got the OBD11 I go to clear the CEL and came across misfires throughout this period and still do. Its not a misfire that you clear and pops up immediately. You clear it and it wont pop a CEL until 4 days or a week sometimes or longer. I replaced the spark plugs and coils around 41k so my mechanic doesn't think it could be that. I don't think its carbon cause my cold start up isn't rough it idles smooth. CEL will pop up when driving somewhere normal with no beans. I have been documenting the misfires onto my notes for a while now. Don't judge as I have been still driving the car as its my daily. What has me concerned is I noticed the biting point taking a lil longer unless I am tripping. I admit though sometimes I don't give enough rpm in first. All the other gears the car drives good. Another thing thats so hard to explain is the noise I get when engaging the clutch (happens sometimes) is like a creaking/chatter coming from the front under the dash. Sometimes its a very quick noise when hitting the biting point or if you don't give enough gas the noise will b slightly longer say 2-3 seconds. For the misfires could it be bad injectors? I ONCE had my car get CEL & EPC light and car started to shake happened on 8/19 code.

As you can see I am getting misfires in almost all cylinders but #2 being the most. What you guys think it could be? Engine bad? Crankwalk? Squid Game?
I always fill up 93 oct. At one point I was using Costco and my shop told me to stop filling up there. Misfires went down but still appear. Oil changes always done at 5k miles. Car is never tracked and has seen a few mexico streets and tons of WOT for fun like 2nd and 3rd gear rips. I should post this on MK7 Confessions, I used to launch this car often in its early days, wish I never did.
