Anyone with a spare turbo boost actuator...

[BethlehemLotus]

Already replaced the gauge and that made no nevermind. So it must be the rare actuator, no? (Or can I live without it....)

Thanks for any help.

It's kinda had working out what you're asking!!!

Are you looking for the wastegate actuator (on the turbo housing)? Or the boost gauge transducer (red rubber covered sending unit on the fender) that feeds the gauge?
Also, where are you located? (It's always a good idea to have this in your profile.) Depending on these answers, I may be able to help.

Just picked up a used actuator, though I am not able to locate it in my edition of the manual or on my M100. Nice to know that there is another possible culprit for my pinned gauge (new) on the fender.

OK, reading between the lines, you have a boost gauge with a needle permanently pinned one side or the other. Correct? and you have replaced the transducer (orange thingie on the fender in the engine compartment) and it's still pinned. Also correct?

If pinned all the way left so always reads "0", check the ground on the transducer. You might even run a jumper wire to the engine and go for a drive to see if that clears it. The ground can be troublesome.

If pinned all the way right so always reads full scale, check the wires on the back of the gauge. chances are the ground wire and sensor input are reversed. The correct positions are in the wiki. Click here to go to the wiki page.
