Corsa D 1.3 CDTI possible turbo problem

**bulld** · 17th March, 2016, 02:14 AM

Hi Guys
Hoping someone can help, The car hits about 3000 rpm and the engine management light flashes on and off quickly and the car will no longer go above 3000 rpm until i turn it off and restart.
Just before the engine light comes on the car does pull away , but just for a second.
I have checked the wastegate actuator and i dont see it move at all , i tuned engine off and had a friend turn it on and rev to 4000 rpm ,
The wastegate actuator doesnt move. I tried moving it with a screwdriver with the engine off and it seems to not budge at all.
Before stripping out the Turbo it would be great if someone could suggest anything else

Much appreciated
Bulld

Yes you need to get it code read instead of guessing. If the light was on there should be a code.
you need to study live data whilst it faulters.
Live data will tell you quickly if it is overboosting.

Going to check with opcom today, I am not experienced in diagnosing live data , If i post the live here could you help look at it
Thanks in advance

Hi Guys
here is the live data , i hit 3rd gear and immediatly the fault light flashed up , and now have overboost error again after i cleared it earlier friday2.rar

I notice the oil pressure flicks to low at line 192 , could this be all the problem is

?

Make sure the acuator arm isn't sticking. Or use GFF on Tis.

Corsa running perfectly now , It was a stuck actuator
It must have been pretty bunged up inside it took a lot of force to free it up but i managed to do it without removing.
It will probably need removal and cleaning in the future , for now its repaired
