    Default Please help?? 1.9 cdti 150 limp mode p1125

    Hi all could anyone help me?? I have a 2004 vectra sri 1.9 cdti 150. I haven't had it for very long, all was fine the car drove beautifulyup until I was on the motorway stusk in traffic. When the traffic cleared the car went into limp mode as I tried to accelerate back up to speed. I pulled into nearest service station, the spanner light and engine management light came on. After a few minutes the car was running fine but the lights stayed on. The green Flag guy plugged it in and came up with code p1125 and said it was the apps. Whatever that is? I'm no mechanic!!! He cleared the code and all was fine for 160 miles when it happened again. I've had it plugged in by a local garage and the code still came back the same. I understand that there are 5 sub codes but every time I take it to the garage there are no codes. Apart from this problem it runs absolutely fine I've cleaned the EGR but it still does it.

    Sorry for the long post I'm just at the end of my tether and can't afford huge garage bills!

    "P1125 Throttle position sensor intermittent" I believe.
    Now I need a turbo to keep up!

    Thanks big sig, does that sound like a new throttle body do you think? Any idea how much these cost?
