So I'm assuming that is my issue honestly don't know what to do with this information I think I'm selling my dream car . What's crazy is I've never driven this car hard I've babied it Oh. Sorry to hear that. From what I can recall reading wear limit is 101psi and max differential is 43psi per cylinder. I will try and confirm in the vw manual I have. Technically, you'd be within that. But 27 is quite high and you have to wonder if that is the cause or contributing given its the problem cylinder. What did the plug look like. Is it fouling? CJXC compression tolerance in vw manual.

JDvanb Posted September 23 Author Report Share Posted September 23 @fastandy the plug looks fine but I'm gonna do a compression test myself this weekend I just bought the tool I don't really trust that shop anymore but I have a feeling they told the truth I believe it's been like this since the day I bought it which is sad I may not give up on it but haven't made a decision yet Quote Link to comment Share on other sites More sharing options...
JDvanb Posted September 24 Author Report Share Posted September 24 So I did a compression test myself cause mechanics suck and my actual readings are 160 psi on all cylinders except the first Which is like 135psi so there's an issue but not as bad as the mechanics made it sound idk if they lied or their compression gauge is way off but glad I did it myself fastandy 1 Quote Link to comment Share on other sites More sharing options...

You're still looking at 25psi differential to cylinder 1. Is it the cause of the misfire though?... it's not out of spec but it is the problem cylinder...co-incidence only or root cause?
