Thanks @mmi ill try those ASAP.
Realised the video links above didn't work so hopefully this YouTube one will work

Yes, this video works for me.
Indeed, interesting behaviour with internal moment - just need to find out the reason behind.

Bit of an update,
Firstly swapped injector 2 and 3 over and recoded.
This made no difference to the misfire or vagcom readings.

Then checked compression, didn't seem too bad at 300psi.

Then dropped a set of verniers down the injector hole to measure the top of the piston. Cylinder 2 where I'm getting bad readings from is 2mm lower than cylinder 3. Re measured multiple times and had a few people try and always 2mm lower on cylinder 2.

Would 2mm be enough to cause the strange internal moment readings and such a bad idle and misfire but fine when warm? Guess it's a slightly bent rod on cylinder 2

I see the last question wasn't answered on this, does anyone have an answer as my brother has a similar problem. Thanks

Hi, so I purchased this van and was aware of the issues.
The height hadn't been measured correctly so I'm glad we checked before a strip down.
The idle was really bad and almost cutting out sometimes
However unfortunately we did multiple things at once, I'm no mechanic I'm afraid but the garage did - New Air maf sensor, new injectors, blanked off the egr valve and programmed. This completely sorted it so panic over
They thought it was the egr causing issues due to some live reading they saw.
Sorry I can't help more
