So I tried to start my 2.0TDI crmb engine this morning and I had crank with some spluttering but no start. I've had this a few weeks ago but after a few cranks got it going, but today no luck.

It's cranking between 500-1000rpm, glow plug light is off and after failing to crank i getting brake manoeuvring unavailable. I have a new battery replaced on Thursday and coded correctly, tested it and it was showing at 12.4v.

Any ideas on what it might be? Anything to test?

I would have said 500-1000rpm was pretty fast for just cranking. Wonder if the crank or cam position sensor has failed. Reckon a scan with vcds or similar might be in order. The brake manoeuvring unavailable may be down to the long cranking and voltage drop. As said see if there are any fault codes stored.

Glow plugs? As @Alasdair1 says, get it scanned.

So scanned it no codes, thinking it may be a sticky throttle body. I had the issue a few weeks ago and pressing the accelerator got the car running.

Tried cranking it again and it the engine is spinning up to 1000rpm before dying so kind of implies it is starting to fire but is failing, fuel pump is activating when cranked, looks like it will have to go to someone to get this resolved.
