Glow plug faults on 2.0 TDI VRS (07)

[daemon]

Hi all, I been reading a lot about glow plug faults( engine light on), but till today I haven't found a solution. 

 

I already changed wiring harness, glow plugs and glow plug control unit (038907281D), but faults still pop up.

 

here is log from VCDS

I have the same issue with 2010 skoda laura 1.9 pd with just 16000 kms. The dealer first changed the radiator fan which cost me a lot but wasn't solved, now it's been there for more than a week without any results. Am wondering if your car has hiccups when accelerating hard?

No I don't have problems with hiccups when accelerating.
