Sam1486 Posted August 26, 2023 Share Posted August 26, 2023 Hi all did a cambelt change on my 2.0 TDI yesterday, all seemed to go well with locking pins placed and crank locked with the tool. Rotated the crank twice and reinserted the pins to check all ok. Put it back together and it just turns over and doesn’t fire up. I did remove the pipes to the fuel filter for better access, but it should self prime, checked the filter housing this morning and it’s all topped up with fuel. I have a very basic diagnostic machine and it’s picking up no fault codes. anyone have any further ideas? cheers sam Quote Link to comment Share on other sites More sharing options...

Magnet Posted August 27, 2023 Share Posted August 27, 2023 Hello Sam, Despite the fact that you don’t have any codes showing on your equipment, it might be well worthwhile checking all connectors that you may have disturbed while renewing the cambelt. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Sam1486 Posted August 29, 2023 Author Share Posted August 29, 2023 Many thanks for the suggestions chaps, turned out I had stuffed up the timing by a few teeth 😱 Stripped it all down again and retraced my steps, timed it all correctly and she started first time. Perhaps the cam sensors prevented her from firing to protect the engine (thank goodness) running sweeter than ever now. cheers Sam 2 Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted August 29, 2023 Share Posted August 29, 2023 Congratulations. Count yourself lucky no engine valves or pistons were damaged. Quote Link to comment Share on other sites More sharing options...
