    Default car is slower after cleaning the boost sensor!?

    I spotted a how 2 on here on how to clean the cdti 150 boost sensor so gave it a go. Mine was solid with gunk when i got it out, got the heavy stuff off with a flat blade screw driver and then blasted it clean with brake cleaner.
    Refitted it and the car drives fine but the hard acceleration has vanished, no longer throws me back in the seat once it hits 2,000rpm.
    What have i done!!?? Have i broken the sensor?

    As above, you may have damaged the little sensor bit in the middle, really shouldnt use a screwdriver on it. See if someone nearby will let you borrow theres for half an hour to see if it makes a difference. I think they're only about £30 IIRC

    Think I've broken mine too to be honest. Same as you, I used a screw driver.
    Those sensors ain't cheap either at around 40 squid
    The diagnostic software has the option to test the sensor - haven't tried it yet though.

    It's one of these things, Live and learn. But see if you can try out a mates first. I think theyre the same in the astra and zafira 1.9 aswell. No point throwing money at a problem unless you know its the solution. Hope you get it sorted soon

    Live and learn eh guys! Think i'll just fork out for a sensor, pretty sure ive damaged it as the acceleration isnt half of what it was, mind you it still pulls, great engine. Thanks for all the replies

    I used Methylated Spirits and a small hard bristle paintbrush worked a treat for me
