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 / advise please.

 

Thanks 

 

 

 

 

 

Don't waste time and money fixing the glow plugs, the 1.9 starts fine without them.
