Im not having any luck just lately !!
Hello all, about a week ago i had my c5 2.2hdi defaped and de-cat, it took alot of sorting out but after new Maf and secondhand intercooler and ecu decode the c5 was ansolutly flying i also put a new fuel filter in and the old one looked really brown!! ok ive done over 100 miles and car is so good its like day and night with just about no turbo lag at all cumin home from work the other day and one of the fuel pipes to the fuel filter comes off!! no big deal i must have just not pushed it on enuff, put fuel pipe back on and car spot on again!! took my wife out in it to show her just how good a 2.2hdi de-fap will run, parks up outside my house and gets ready for work looking forward to the drive!! 2 hours later goes to car and car wont start? when i parked it ,it was fine? opens bonnet checks everything is connected and all looks good, but i did see a air bubble in fuel line to fuel filter? the odd time when i turn it over it will fire? any ides guys im thinking fuel strarvation?

Thanks
Andy
