Hi, I have a 1.9 TDI golf 59 plate, engine suddenly cut out having been running perfectly. Looks like the aux belt ripped itself a part and some bits of it wrapped around the crank pulley, lifted the timing belt and so engine is way out of time. When crank shaft line is TDC the camshaft pulley is about 90 degrees behind. Crank shaft does turn pretty well though. How do I get the camshaft back in time along with the high pressure pump? Can I just take the belt off and turn them into position?
I know there’s probably some valve or piston damage to check for too.

you do not want cylinders close to tdc as it is too close .. here is what i would do ..

remove belt completely.. move cylinders back off tdc about 15-20 degrees ( then all cylinders should be away from the valves . bring cam to tdc slowly feeling for contact, once there bring piston back up to tdc. put on belt, time accordingly , rotate crank twice manually to check for interference. if all clear then put on battery charger and do compression check ...

Same thing happened to me. Was driving on the highway when serpentine belt broke and wrapped itself around the pulley putting the car out of time. Unfortunately in my case valves were bent and I had to replace the head. Changed timing belt as well while I was at it since it may have been stretched.

Been running fine after that. It's been 2 years

Cheers for great, valves were bent as well in fact so I’ve ended up taking the whole head off and changing them, one of the tapits had also broken!
I’ve got it all back together but can’t get it to start, turns over fine but no ignition. Timing looks fine visually watching the cams as I turn the crank round. Will it stop itself from starting if there’s a timing fault code going or something? I’m probably missing something obvious, any tips on diagnosis?

Most people here with the same no start issue after timing belt replacement have been able to resolve it after realizing they were off timing by a tooth or two. I would start there. If not then check if you are getting fuel thru the HPFP

how long has the car been down ?
Perhaps the fuel system has deprimed. Happened to me a couple of times. should be able to look in filtter housing and see.
There is no failsafe that will stop it from starting in the software.

if this is the problem turn on and off the igntion 30 times or so without starting the engine. you will hear the fuel pump run for about 5 seconds each time. Then crank to get it to start. dont crank for more than 20 seconds . Let the starter cool down for a few minutes then try again.
If this works the issue is a check valve in the fuel pump, one can be added in the line for a few dollars.
