Hi is there a book anybody knows that tells you the injector values when testing them on diagnostics thanks

Hi sorry on Vectra 19cdti the battery light comes on when I start in morning but if I switch car off and restart the light goes out and stays out rest off day read somewhere that need to check feed to ECU but wondered what pin number it is thanks

Hi bloke came and put diagnostics on today and said egr was not right but had new one last April and has been cleaned a couple of times , there was no codes today just he said it was stuck at 100% and something else was 40 and not moving when revved how can I test it thanks

Battery light should come on when engine is not running.
Be careful on how you clean the throtle body because throtle plates may loose corect position and become stuck. If that hapens you will most likely get egr code and engine malfunction light.

When cleaning egr use stove cleaner as its helps losen the carbon. You should clean egr gass cooler and piping. Befor doing this job you shoul have diagnosed the car and see if egr is working corecly on comand as this might not be the fault. Usualy if egr stays stuck open you will not get boost. If it stays stuck cosed you could get poor fuel economy as the surplus of oxigen needs to be burned.
If your alternator light comes on and off, check fuse for regulator as it might be blown and making contact on vibrations.

Hi I have got op-com and when I go into the output test and then click on egr valve and then press start activate I cannot hear anything either opening or closing does engine have to be running to do this but I also tried to activate cooling fan 1 on op-com and nothing happens is there something wrong with my op-com thanks
