julesbornwithaninbuiltstumble

I saw an earlier thread about a car failing its MOT and generally it was down to bad luck ,/Shame However my van went in for an MOT today and failed and now will not start,Yet it started fine up until the MOT ,I suspect they have blown the engine on test ? Bad luck for me YET they called to say The MOT chap spotted the engine management light was on prior to the test ? They then continued with the test and blew the engine knowing the warning light was on ,Is this still down to my Bad luck or should they have called me and pointed this out prior to the test , Thanks in advance for any helpful comments .>

With the engine light on then the engine will not rev through its max range so how can they blow it?

A cam belt/timing chain failure can happen at lower revs, but I also agree that "blown the engine" sounds like a very vague explanation of the issue.

In reality the OP submitted a vehicle for an MOT, the MOT test can be conducted with the engine management light on, it will fail, but it would also indicate any other potential issues with the vehicle so it is perfectly valid that they attempted to complete the MOT. 

OP, unfortunately this is just bad luck.

Was the engine management light on when you took the van in?
Have you read fault codes?
What are the symptoms of "will not start"?
When was the cambelt last changed, and when was it last serviced?

The engine management light is a fail in itself, on all post-2008 diesels - but it's not grounds for a refusal to test.

The test procedure for smoke opacity involves revving the engine to 2500rpm or half maximum revs, whichever's lower, under no load. If your engine broke doing that, then the test centre are not at fault - it was merely luck that it got there under its own power.
