How hard is it to locate and test the wastegate? There is no reference in the haynes manual?

Any Ideas apart from taking it to a specialist? Dont really wanna do that?
Thanks adam

I have just replaced my wastegate for a stronger one as my old one wasnt holding boost I would think the only way to test them would be to get a good accurate boost gauage attached to your car.. It is a fairly common problem, particularly on modded engines. The wastegate can become loose and not close properly.. Some can be tightened, a fairly easy job..

The wastegate is attached to the turbo, which is at the front of the engine under the heat shield. In this pic its the brass coloured part.

Tech 2 can read boost so a dealer or indie can also check it for you. My understanding is that the wategate is controled by the ECU (Trionic 7) however I guess a worn one could open too freely.

What makes you think its a problem?

Finn is the only one I know of with a 9-5 who has needed to change the wastegate, however his is at a high stage of "custom tune".

As far as I know non of the main tuners recommend an upgraded wastegate with their "staged" upgrades.

As I said previously my first upgrade was to about 195 -200 bhp and I was quite dissapointed with the improvement
