mot test

vimot

when my car had the emissions test (in my opinion) the tester over revved the car. After he moved my car to the brake machine he got out turned the engine of had a walk and came back he could not get car started again. I had to get my car recovered by main dealer the out come was the timing had jumped. The test station accepts no responsibility. any thoughts appreciated . Thanks

mot stations display a notice on the wall by the photos of the testers that work there, stating they accept no responsibility for snapped belts etc as diesels especially, have to be revved hard.

The timing belt tensioner will be faulty. Just a fluke that it failed when you were having your MOT done. You are lucky if the valves haven't been damaged. What car is it?

See post #5.

there is no faulty tensioner the car was fully checked by kia and the result where the car was red lined. the same belt was put back on as there were no faults with the belt however the 4 injectors and the wire loom that goes on to them were burnt out at a cost to myself £1200

Can't see thats anything to do with the mot issue. ie, the engine should be capable of being red lined under normal conditions.

One thing that is puzzling is why the engine was revved heavily??. Diesel engines are normally tested at lower revs than petrol, (I stand to be corrected on that). The only reason to rev it would be if it was cold at the start of the test, or if it was struggling with emissions do to "whooly" driving. Revving for a while can shift the soot and crap.
Either way precious little comeback, sorry,

Revved quite high for the smoke test, and there is a risk with the cam belt. It always worries me when I hear my van being tested.
