Hi all,
Your advice may be useful to me.
The problem is that there is a noticeable difference when accelarating my 98MY turbo.
(40.000 km until now.)
Throttle responce is worst in all gear changes. There is a feeling of loss turbo pressure.Revs ok but without the quick response as before.
As I am not expert on details two things may have result to this.
1. The oily Ramair filter I have fitted
at 18000 km. I have cleaned up the air flow meter several times but there is no difference on response.
2. The overfilled engine oil (from the service) that I have discover later,could have done damage to the turbo?.

There is no difference even when I changed the wastegate sensor which lays at the left side of the car, near the filter box.
So, Is the turbo damaged or I have to check the thottle responce controller.

Thanks in advance.
Elias

 

Maybe re-set the ECU ?
