That's the problem with mine at the moment.

Anyone else had it on their vrs?

i had it in cylinder 1, cost me 120 to fix! faulty wiring loom

In my old polo i was running on 1 cylinder when i took it into vw. Cost ke just over 1k to fix as the wiring loom went through oil and had corroded. Hopefully not an expensive fix.

It's more than a injector and wire. Swapped them over and the problem still persists. Head is coming off tomorrow

Yikes....

Usually wiring loom to injectors

Looks like piston ring or a valve/ tappet

If its a piston ring smoke wud usually be blue. White smoke suggests unburnt diesel or water being burnt
