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.. :D

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. :confused:

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