So little old me trundles down to the MOT test centre at the weekend to put my pride and joy through it's annual inspection and yep it failed, due to new legislation if your eml does not go off when the engine has started it is deemed to be a major failure and will result in a refusal to issue a certificate. What frustrates me is that every other aspect of the car passed inspection. I could understand it if the fault meant that the exhaust emissions were outside of spec, but mine reported as normal.
So, I paid an additional £35 to have the codes read. P0010 - Crankshaft position sensor and P0443 Purge Valve for EVAP, electrical fault. The crankshaft sensor is £140 part and is fitted in 2 minutes, my local dealer won't take payment over the phone to order, so I have to go in twice, once to pay, second to collect. The Purge value has me scratching my head as Mercedes have confirmed that my car does not have one! They suggest that they scan using their "STAR" diagnostics at £99 plus vat......
From looking at the wording on the failure sheet, the light has to illuminate and then extinguish, so pulling the bulb out is not a work around.
This I feel is not in spirit with what the MOT is for, it's a test to ensure that the vehicle is safe to be on the road, it used to be written that you did not need an engine to pass it, it was focused on chassis, steering/wheel bearings, brakes, glass and that was it. What worries me is that modern cars all have complex engine management systems and as they age, they are prone to eml warnings, sometimes serious, sometimes very minor.
My thoughts are that this is another ploy to rid UK roads of older vehicles as the cost to repair will not be cost efficient, forcing you to scrap/part out and either buy or lease new. Either way resistance is futile as them the rules. So please keep this in mind if you are in the UK and have either an engine light or a service now indicator displayed.
