G60Jet 1 Posted December 9, 2005 Ok, My missus has a Golf 100bhp PD the diesel engine has developed a misfire on one cylinder, but my question is to any derv boffins, How the hell do a DERV mis fire, Its not mechanical its only intermitant. VAG com is saying misfire and thats about it from what my technically minded missus said, anyone?? Quote Share this post Link to post Share on other sites

G60Jet 1 Posted December 9, 2005 not chipped, recent new starter motor, that about it, not checked any timing yet. could it be a MAF problem? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted December 9, 2005 Probably injector related as a guess Quote Share this post Link to post Share on other sites
CorradoVR6-Turbo 0 Posted December 9, 2005 It will have common fuel rail and therefore electronic fuel injectors like a petrol car but the derv runs 80volts to the injectors instead of 12volts. It also has about 800-2000bar of pressure in the rail.. :crazyeyes: These are prone to screwing up and is soooooooooooooooo expensive to renew. That's why I stick with petrol 8) Quote Share this post Link to post Share on other sites
