  • [Corsa D 2006-2014] corsa d 1.3 cdti

    Hi, I have a problem with my Daughters 2008 Corsa D CDTI ecoflex .She has complained (as only daughters can) that the car would only start after 10 or 15 minutes of trying then when it did start it ran rough . we have had it read and has come up with "fuel rail regulator- no fuel pressure" and "capacitor voltage high".
    I intend to start by replacing the fuel regulator or the fuel regulator sender ,my question is which is the likely culprit , is it just pick the cheapest and hope for the best or am I barking up the wrong tree altogether many thanks A Baldwin

    The problem is that both can fail (and do) and you need to use diagnostic equipment to check which it actually is. They can also suffer leaks in the system, high pressure pump problems and injector problems. It just depends how good the diagnostic reading you had done was. If they've checked everything else and it points to the FPR or the sensor then you can use a scope to check what's going on - or as many workshops do (since these are common to other manufacturers) they keep a spare one to try. That doesn't help you a lot I'm afraid, but that's the problem with modern diesels - they're great when they work and a pain in the posterior when they go wrong.

    It's either bite the bullet and get a proper diagnostic done to pinpoint the issue, or take a chance on replacing parts - but on those it can get expensive very quickly.
