Hello Mark - thank you for your reply..
Its not unusual for the fuse ratings - and even position (!) to be different in the book - Vw / Audi s are terrible for it ! So I wouldn't worry too much about that aspect at the moment - a 15 amp will be fine. If the 10 is blowing - fit a 15.. If that blows then you have either a fault in the Ecu itself -or the wiring loom to it... and that is common..
You need to check the wiring loom extremely carefully - turning / twisting it over to check for any rubbing / chaffing damage - especially where the loom runs close to the engine / body / framework etc....
Any such chaffing damage will cause the fuse to blow and the engine not to start...so you need to check the looms thoroughly - inc the one to / from the fuse boxes.
If you find the fault as above there is every chance that repairing the wiring will cure it -
If not - then the fault is most likely the Ecu itself... Check the connections to it first - and then the next step would be to have a diagnostic test run on the van using proper plug in diagnostic equipment which should highlight the exact area of fault.
Then - if its looking like the ecu - the best - cheapest way forward is to send the ecu away for test / repair to a company that specialises in that - you can find many with a google search - find one to suit you .
New ecu's for these are incredibly expensive so a repair is always best...
Doing as I have outlined above is the best - cost effective way to work through this and get the van operational again..
Obviously I cant see or test it - I am going off what you have described to me .. and that is my conclusion based on your description of the faults - I Sincerely XXXXX XXXXX have helped you - but do ask me if you need anything more..
Kind Rgds, MIKE
