Quick update. Checked all the wires and plugs as best I could but nothing obvious. No pinch points or harness clips broken either. I have taken the car to and from work the last couple of days and no problems, running well. However it's always exciting when I put the key in to see if it'll leave me stranded 😂. Time will tell I guess.

After checking for a non start, called the RAC out. 3 hours later he arrives, turns the key and the b@stard thing starts. Did a scan anyway and came up with DTC: P214600,Fuel Injector Group A Supply Voltage Circuit / Open. No more details and he was on his way. So an intermittent issue with an injector or harness it seems. Got to love an intermittent fault...

Glow plug light starts flashing at ignition on, during instrument warning lights check, before cranking. It's realising something is up pretty much straight away. There's so many relays and sensors I'm stuffed without a code. Was wondering if RAC have high enough level diagnostics? If I upgraded to home start I could call them out.

Dug out an old cheapo code reader just on the off chance it might pull something from the car. No codes but I noticed there was no flashing glow plug light. Tried it on the key and it started. This is on the old battery. Stopped and restarted several times as normal. Bought a new battery today as per the consensus of advice. Before I fitted it, had a quick try. Flashing glow plug light, no codes and no start. New battery in, glow plug light flashing, no codes and no start. Brilliant. "Clearing" the non existent codes using the reader clears the glow plug light but just reappears with next attempted start. Any ideas?

Very true, I'm just trying to avoid throwing parts at it and hoping for the best. Consensus says it's the battery so I'll do that. Fingers crossed it's a 90 quid fix.

Put the battery through a "recovery" cycle and full charge. No change though. As soon as the ignition is switched on, before any cranking, the glow plug warning light starts flashing with the CEL. Cranking from that point drops the voltage to around 7v again. Looks like a trip to the motor factors is required. If that doesn't work I may need to call on a forum member with VCDS. I've checked the list and there may be a couple of fairly local guys. Is it a case of direct messaging them or is there a corner of the forum for placing calls for assistance? Thanks again for your replies.

Googling (always risky) indicates that the voltage should stay up at a minimum of 9v during cranking. I'll look to solve that as a next step.

Thanks for all the replies. The Code reader is not VW specific. It's one I have for Porsche codes and service light reset. Should display any ODB2 codes I would have thought? Live voltage shows an ignition off of 12.2, ignition on of 11.8v but a drop to 6v when cranking which seems too low, although cranking speed is quite good. What's the normal battery voltage during cranking? Will try a full battery charge and see if that makes a difference. I'll take a look at the VCDS map to see if there's anyone local (Burnley).

Good morning all, Searched the forums but nothing pops up for this issue, so here goes. Engine (2010, 105PS CAYC, 100k miles) will crank as normal (battery seems healthy) but will not start. Extended cranking just results in a dashboard chime (telling me to stop?). The glow plug symbol is flashing indicating a fault but my OBD2 reader says no codes found. Car was running fine when I parked it up last night. Google search says it could be anything however there is a Youtube vid which points to the low pressure fuel pump in the tank being duff. The only symptom which may be linked was a massive flat spot once when pulling away from some lights, but only occurred once, a couple of weeks ago. Any help much appreciated. Cheers.
