Omega General Help / Re: Turbo loses power...2.0 DTI

« on: 11 May 2012, 11:58:09 »

Talked with an Opel mechanic today and he did not think it was the turbo either,but with that km on the meter and without the history about what have been done to the motor the latest years he thought the best idea would be to take off and clean the intake manifold and EGR. It is a threepiece intake on this motor and he said the middle part often got clogged/filled with sh#%"t....

Thanks for reply.

Omega General Help / Turbo loses power...2.0 DTI

« on: 10 May 2012, 22:01:29 »

My resently bought 2000 model Omega 2.0 DTI is missing some power.
Had a mechanic hook up the computer while testing the car and everything looks good and no codes came up,exept for the turbo. The pressure goes up to about 1,and drops to about 0.5,up to 1,and down to 0.5...and so on......
This happends everytime you accelerate,it starts  about 2000 rpm, I doesnt feel it much 1-2-3 gear,but i feel the power drops very good in 4-5 gear.
There are no vacuumleak,and wastegate seems to woork as it should......do i ned a new turbo....or anything else...

I really hope to get this sorted out without having to change things it just might be....

Hope you understand what this Norwegian is writing here and i really would be thankful for any ideas who solve my problem:-)
