Hi all,
Hoping someone else has came across this issue and is able to advise please.
My 2010 mk2 Octy 1.9 tdi has recently developed a starting fault where is cranks (very fast) but doesn't start. At first I thought it might be the fuel pump in the tank but I can hear it priming when the ignition is on. It ran absolutely fine before this starting issue.
Plugged in the fault code reader and it came up with 5 codes:
1 - powertrain data bus missing message from instrument cluster (cleared codes, tried starting again and this did not reappear)
2 - Glow plug for cylinder 1 open circuit
3 - Glow plug for cylinder 2 open circuit
4 - Glow plug for cylinder 3 open circuit
5 - Glow plug for cylinder 4 open circuit
(All Glow plug open circuit faults reappeared after clearing the codes and tring to start the car again).
At first I thought it was a fuel issue, but after seeing the codes for all 4 glow plugs, I'm thinking it may be an issue with them / the glow plug unit? Also thought about the camshaft / crank position sensor, but there is no code showing for this.
Would really appreciate any help / advice please.
Thanks , Kev
