    Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
    Hi, new to the forum. I’m having a problem with the lambda sensor on my car, this all started when my engine was about to stall at a roundabout but I caught it and dropped the clutch and it bounced back into life, next thing the EML was on. I checked the diagnostic code and it was P0136 and...

    Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
    Hi we have a Corsa which has failed amongst other things, on the exhaust emissions. I think that it maybe wasn't at correct operating temperature when it was tested, but any other ideas that could cure it would be greatly appreciated. I have attached the print out for info. Cheers Derek

    Hi, after reading a lot of threads, posting a few and trying various things, my Z16XEP Astra 05 isn't getting any better. The problem: car jerks/twitches between 3000-4000RPM accelerating and holding it for a few seconds (trying to overtake a long truck for example). It just loses power for a...

  5. [Zafira B] [05---] Exhaust/O2 Lambda Sensor - is there a difference between pre and post cat?

    Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
    Hi All, Just a quick question. I'm going to change the exhaust on my 56 plate Zafira 1.8 petrol and before we got started today my cousin (who is helping me) suggested that I get a replacement sensor for the front pipe as when he's previously changed exhausts they have snapped due to rust. I...

    Hi, I'm new to the group. I have a 2004 Vauxhall Corsa Energy 1.0 and yesterday evening the emissions light came on. I plan on taking it for a diagnostics run at lunch, but I have manually obtained the fault code P0420. I'm hoping it's the sensor playing up and that the diagnostics will wipe it...
  7. [Corsa D] [06-14] Lambda Sensor problem

    Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
    Hi, a few months ago my whole exhaust system fell off due to corrosion and was replaced. Shortly after, my engine light started coming on. Diagnostics revealed it was one of the lambda sensors so I had it replaced. After a week it came on again, this time it was the other sensor. Now, after...

    Hi, I'm pretty desperate and was wondering whether someone could help. Mine is a Vauxhall Astra 2006 1.8 Dual Fuel. It failed emissions for it's test with a reading that I was told was the highest reading he'd ever had. So I replaced the CAT to a brand new one, new lambda sensor, the MAF meter...

    Astra, Corsa, Zafira, Meriva, Adam, Agila, Combo
    Hi, I have a 1.4 petrol Astra hatchback registered 2002. Recently the engine management light came on and after checking the codes it was determined it was the o2 (lambda) sensor. After driving the car in this condition for the last 3 weeks the light has now gone off, so maybe it has cleaned...
