My books show it as a interference engine in which case valve damage is most likely to occur
however if that was the case , it would be having a miss from the start and would not run 2 weeks before something happened
if a valve spring breaks there could be valve piston contact but it is doubtful if that would destroy the engine but again breaking valve springs is rather rare on diesel engines
the engine would not just quit but would rattle and bang it's head off then develope a big noisy miss from a hole in the piston
so I suspect a timing belt problem from when they removed/replaced the head after the glo-plug fix or a crank/cam shaft position sensor or wires ( possible faulty connections for the cam shaft)
I would suggest finding an accredited service center for a proper diagnosis and quote for engine repairs

The flashing is telling you that the engine is mis-firing, the dealer will run a test to determine the cylinder that is mis-firing, chances are it is something simple
they set the timing WRONG and that is an interference motor so the valves hit the pistons

Hi, im afraid i can only give you bad news im afraid, if the engine was running even on tick over when the belt snapped then this would have caused the valves to smash into the pistons as the top half of engine would have stopped spinning leaving at least 2 valves in the out position but what causes the damage is the bottom half of the engine, as their is no weight on the cams to keep them turning they stop at once but the bottom half the crank has a big weight called the fly wheel now when the belt snapped the cams would have stopped dead but the crank would have carried on turning under its own weight and this is what causes the piston or pistons to hit the valves this then causes the valves to bend and all the valves will need replacing and the whole top end rebuilding with new seals and the new valves and valve seats will need grinding in.
how ever as its only usually the top half that gets damaged you could save yourself some time and money by calling a local breakers yard and see if they have a cylinder head lying around or even a whole engine as the cost of rebuilding you head and engine would cost more than it would to get a second hand cylinder head or if you didnt want to take any chances look into getting a whole engine.
look at the costs involved get a quote off you garage for the head rebuilt and new valves, tell them worse case if it needed complete head rebuild with all new valves and valve seats and all the seals get a price on the whole job then ask them how much it would cost if you supplied a working cylinder head or even whole engine then compare the prices and check with some breakers for cylinder head prices or engine and you should find that a second hand head will work out cheaper than having yours stripped and rebuilt with new parts.
let me know how you get on or if you need further assistance ok
please rate this solution as i have a whole page of unrated posts, thanks

not sure here as the older model i worked on with a izuzu engine or was it toyota was under the bonnet ,what happens here a lot with the electronic is that when some electrical components get cold its affects the function of them ,Now what this old diesel fitter does to old motors and even new ones i might add is to fit a manual overide ,a push button switch on the dash that makes the relay click in manually or a heavier cable from battery direct to heaters via the heavy push button switch ,then when its really cold you give it some manual overide ,say hold button in for the count of ten then crank engine whilst still holding the heaters on ,cant beat some of these old fashioned ways
how could they check for head warpage if they didnt pull the head and put it on a plate? Im calling poor diagnosis.
