Misfire Logs

If youve ripped it out theres your problem then.
Its a very well known design fault. I bought mine over the winter and noticed it was soaking wet.
I followed a guide on here nearly a year ago now and its still holding up well.
Just type in Mk 2 leon sealing bonnet strip and it will come up. The guide is by TimSwarf i think.
If i was you i would do that before winter arrives and buy a new bonnet lining incase a little water still gets through, cus if your taking the engine cover off it will only get worse and probably on all four coilpacks.
Thats what i would do anyway.
P.s How was your Apr remap and would you recommend?

"Not misfire at all" "Anything more than a handful and you have a problem"
So you say it shouldnt misfire at all but then say a handful is ok.
So witch is it lol
Both
Earlier in this thread you stated a regular misfiring is common and nothing to worry about. I stated they shouldn't misfire at all.
A couple of misfires on the VCDS counter isn't enough to start ripping the car apart looking for answers and can be explained by a number of things.

"P.S These engines do seem to throw up occasional missfires tbh." I said occasional not regular.
"Also slight miss at idle seems common place with these engines and not usually anything to worry about imho." What i mean by this is a slight miss i.e Not silky smooth ( Not rocking its tits off!lol )
In my experience and what ive researched many many many 2.0 Tfsi's dont have a really smooth idle and imho like ive said doesnt worry me.
No doubt there will be an underlying cause like engine mounts, pcv valve or many other things but if its only on idle and not under load then i wouldnt be investigating lets put it that way.
Also when i say a slight miss i mean not registering as a missfire on vcds, just the odd judder.

If your car is at 76k, I would definitely recommend cleaning the inlet valves and runners. I just did mine (67k) and they were minging. Absolutely caked in gum and carbon.
I also changed the injector on the affected cylinder as I didn't want to have to remove the inlet twice. If you do go ahead with it, I'd recommend replacing the fuel pump cam follower while you are at it. It's a cheap part that is easily fitted and will give you one less thing to worry about.
It's a pig of a job to do so if you aren't too confident carrying out mechanical work, I'd get a garage to do it. I'm a marine engineer so it wasn't too bad, just awkward as hell due to my sausage fingers
I've read some good things about the walnut shell blasting process (we do a similar procedure every second day on large slow speed diesel engine turbochargers).
You'll notice that the car runs far smoother and the throttle response is much sharper too.
