We have a couple of the new opeladores at work. Since November we've had multiple people commenting about...
(i) the dash screen suddenly flicks off and on - or at least dims to almost off and comes back up.
(ii) a 'ding' is heard through the speakers on the driver's side of the car
(iii) the car suddenly slows,
(iv) the Check Engine light comes on
(V) a message comes on the dash saying the car has reduced power to protect the engine.
In several cases the driver pulled over, turned the car off and when it was turned back on (either by a roadside assist jockey or the driver) the car returned to normal operation. Sometimes the check engine light would stay on, other times it was gone. What made it even harder to track down was that if the car was left in the parking lot at the back of the offices, or in the drivers driveway at home, next morning the check engine light was always gone when our in-house guy would go plug in his little code reader. So from our point of view we had nothing to even prove it had happened... until this week.
It happened once to a 2Lt Calais on Monday just before he got to the rear carpark... so we got to see the car in low power mode AND read the code before he shut the car off. And today it happened to my Calais-V about 3 blocks from work.
In both cars the code returned was P2138 which tracks back generically to a throttle problem. At first our guy thought it was one or the other of the two little motors in the throttle body itself being out of voltage... then he realised that the code when specifically matched to the current Opel Insignia B actually concerns the throttle sender unit on the accelerator pedal. He found he could replicate the issue in five of our Opeladores simply by wiggling the wiring looms up under the right hand side of the dash with even a small amount of gusto!
Great.
He is going to see whether he can identify an issue in the female plug that connects to the sender/sensor unit. If not then try and track the five wires back and see where they go and any other connectors in that area they pass through. If not, then he says he will see whether taping down the wiring looms a bit better helps.
