Hi my glow plug lights came on and there was a bubbling noise coming from diesel pump send/feed unit it then went into limp mode. After restarting engine it seemed to clear then came back on again. I changed the diesel feed part from the tank same symptoms came back within 3 days and now it’s the same problem it starts and splutters and makes same noise again and goes into limp mode.
 

It’s now been on a diagnostic and it said glow plug problem should I change them?? It also said I have insufficient diesel pressure

 

any ideas on what it could be or what to do next??  Thanks in advance 

Might get a better responses in the Octavia forum? 

Thanks I didn’t realise I was in the wrong forum 🙈🙈
