  1. Help with Fault Codes please (Vivaro 1.9 Di 2002)

    Movano and Vivaro (including Renault/Nissan Deriva
    Hi all. 2002 (52) Vauxhall Vivaro 1.9 Di (118,000 miles) I have got myself one of the Delphi Clones just to read codes and help diagnose. I have read the codes, cleared them and now covered a couple of hundred miles and these are the codes that come back. P0400 - Exhaust Gas Recirculation...
  2. [Astra Mk4/G] [98-04] Astra G (MK4) 1.6 8V - So many issues, desperate for help.

    Car Audio / Electrical / Security / Diagnostic Rel
    Hello all. Absolutely at the end of my tether with this car - really need some professional help. Mates bought a MK4 Astra 1.6 8V a couple months ago. It's been a piece of s*** since day 1 (though it drove like a dream both times we went to see it before buying it). Have fixed lots of other...

    Car Audio / Electrical / Security / Diagnostic Rel
    Hello all. Long time browser first time poster so I'll just jump right in. Could be a longish post so be warned but I'd really appreciate some input and help. My mate bought a 2003 Vauxhall Astra MK4 1.6L 8V off a sweet old man a couple days ago. It only had 58,000 miles on the clock. We...
  4. [Astra Mk4/G] [98-04] Astra g - crank sensor p0370

    Astra, Corsa, Zafira, Meriva, Adam, Cascada, Agila
    I have a 2003 astra 1.7 dti with the Isuzu engine. Been getting fault codes p0370 and p0400 popping up with increasing regularity. The car also seems a little heavy on diesel (for this engine anyway) and also does a funny sort of blipping/surging type things whne warmed up and on very light/part...
  5. [Corsa D] [06-14] 2008 Corsa (1248CC) P0403 Fault Code

    Astra, Corsa, Zafira, Meriva, Adam, Cascada, Agila
    My Engine Management Light appeared on my dashboard a couple of weeks ago so I decided to get an OBD reader to try and establish what the issue was. The code P0400 appeared which led me to believe that something was wrong with the EGR Valve itself. I've admittedly got barely any experience with...
  6. [Vectra C] [02-08] EGR Flow Light p0400

    Cavalier, Calibra, Vectra, Signum, Sintra & Insign
    My Engine management light sometimes comes on randomly when I start the engine (never when it's already started) It flags up the code p0400 for the EGR Flow. I have had the car carbon cleaned that should have cleared all the carbon from the engine.. I have also taken my EGR off and gave it a...

    Astra, Corsa, Zafira, Meriva, Adam, Cascada, Agila
    Hello Everyone I have a Astra G, bought it back in 2013, everything was fine until developed a missfire, the driving got quite bad as car would jerk/kangeroo. That's where the journey to getting it sorted began, I will try, fail, park up, try, fail, park up, everytime thinking I'm close to...
  8. [Vectra C] [02-08] Vectra 2007 CDTI - Help?

    Cavalier, Calibra, Vectra, Signum, Sintra & Insign
    Hi, hoping someone can help. I have a Vectra SRI 2007 CDTI and the engine management light keeps coming on. Although I have reset it myself it keeps giving me a fault code P0400: Exhaust Gas Recirculation Flow. Because this can be linked with the EGR valve I was going to get a Carbon Engine...
