I drive a 54 plate 9-3 1.9TiD 120Bhp and the turbo seems to be a distant memory. I lost it after the really cold night that we had, -18 in my area. From this point it went, wasnt gradual it just went the next day i started the car. Since then it has driven really sluggish with the gas pedl to the floor.

The symptoms i have are:-

• slow or even a gear change needed up a hill
• overtaking is not possible in the high gear range
• If i drive it in one gear and let the revs get high, once it hit about 3500 to 4000 on the rev counter there is a big jolt and loss of power
• If fault codes are cleared, it drives like normal for 5 min then drops power again.
• These codes always come back
  • P1125 - Throttle Actuator Feedback Signal Range/Performance
    (21) - Not present
  • P0638 - Electronic Throttle Control Circuit open
    (04) - Not present

I have had 2 mechanics look at it to check the hoses, mentioned the innercooler (not sure if checked tho), EGR valve, connections and sensors. I have fitted a new air flow meter and still got the issue. Before it gets expensive i was wondering if the experts on here had any ideas. Do the fault codes relate to my issue? I did have these codes before the power loss so not sure if related. any help will be greatful.

it very possible both codes are being caused by the same fault..

Sounds like throttle body is shot.
