Hi there,
I’m having an issue and quite lost right now. Over the last few weeks, I started to notice that I had some knock between 1000-2000rpm. I thought that could be caused by worn spark plugs and I replaced them (gapped to .7 and torqued at 22nm as per VW manual) and new APR coil packs. The knock improved a lot but still there. It's an EA211 CXSA engine at about 115k KM.
At the time when I had the plugs out, I did a compression test in all for cylinders (I think I did right) and all them came between 130-145psi (VW says when new between 145-210psi, max wear at 100psi and max of 40psi between them).
I spoke with the company that done the tune for me and he told me to gap the spark plugs down to .4 due the extra boost. He also prompts to do a log and see if there was anything wrong with the tune. In the logs showed that the cylinder 2 and 3 was pulling time up to 9,5 degrees in some cases!
He put the original tune back and the car still pulling time but this time around 4 degrees and the time being pulled randomly between them, not necessarily the same cylinder pulling 4 degrees. Sometimes number 2 pulls 3 and the 3 pulls 1-2 degrees and another time the 2 pulls 1 degrees and the 3 4 degrees.
I checked the stretch of the timing belt through VCDS and is saying that the camshaft is correcting by 5.3 degrees (VW says that anything over –/+ 5 degrees the belt/chain needs to be replaced ASAP). I have the car booked to do the belt this Tuesday.
I don’t know if that is happening because the camshaft is correcting too much or if there’s something else wrong.
Anyone here had or heard about this issue?
Thanks.
Guto.
