My 2008 golf had the glow plug flashing light coming on at 65 mphbin 3rd gear. It went out once the engine was turned off and on again but would repeat at 65. Today when I turned it off and on the glow plug went off but check engine lit up.

This is a good video applied to my 2005 b6 2.0tdi aswell. Two things I noticed before fuel pump went car didn't always start well had to tap accelerator and when driving fast 3 and 4th gear there would sometimes be a stutter at top revs. Changed fuel pump and put In a new Mann fuel filter And car now starts and performs better with no random stutter

A good explanation here which covers the correct way to go, iv'e just done this myself.
