Number of things been known to cause this, but its such a pita to track down tbh mate, of known issues when car is hot, fuel supply issue, coolant senders, maf.

When did you last change your fuel filter btw?

a one mothe ago had a service with fuel filter and rest of filters change, but this problem with engine i have got abou 1 year, and nobody know what to do. I thougt about fuel filter, but is not. The bigest problem is injector no 2, you can see on logs. Have you got maybe instruction how to change injector in my car? PD injector, 1.9 AWX engine. Thx
