Is there any way to test that the stock turbo boost gauge is working?
Also, does anyone have a pic or can explain where the sender for it is located please ?
Thanks

Re: Turbo boost gauge testing
Stock boost gauge is just to show you are on boost and that's about it.
Re: Turbo boost gauge testing
Signal is taken from the cars map sensor on a rev3+ I believe .. rev1/2's have a separate map sensor for the boost gauge .
Has the stock gauge packed up .

Stock boost gauge is as much use as a one legged cat trying to bury a turd on a frozen lake

All revisions - pressure sensor next to diagnostic port.

How you getting on Ruth .. whats the problem your trying to sort .
Re: Turbo boost gauge testing
Sorry, I've been trying to get more info out of my husband as he's the one working on it.
He's just taken me out and shown me. The best way I can describe it is that it's behaving "erratically"! He tried to show me when the car was stood still by revving it from the engine bay but the gauge does nothing at all then. So we took the car out and it does kinda work then but it seems to be all over the place. Nothing, then full boost, then back to nothing, then half way and when you expect it to hold there it again drops to nothing.
He's wondering if he's knocked a connection somewhere whilst working on it or maybe there's a leak as he didn't think it did the same when he drove it before... Wondered if there was any way to test it. He says it still drives fine as far as he can tell, but we're not really experts on it as it's hardly been driven yet.
I hope that makes some sense?

Re: Turbo boost gauge testing
Sounds like the stock gauge has failed Ruth .. buy an aftermarket gauge and disregard the stock ... that would be my advice .. it takes a signal from the cars map sensor on a rev3+ , if that had problems the car wouldn't run right.
Swopping clocks just to check/sort this would be a pain

Thanks, we'll look into that then

Correct. Engine doeasn't create boost when not under load.
The OEM boost gauge doesn't act like an aftermarket gauge. It basically reads nothing or boost. Not much in between.
Re: Turbo boost gauge testing
Exactly .. what is the problem you have that needs sorting .

Well, that's the question really I guess! Sounds like from what Peter says, it's behaving as expected, so maybe we don't have a problem?!
I don't personally know as have not paid much attention to that gauge yet, have only really driven the car once! Hubby seems to think it used to behave differently, less "bouncing" all over the place but maybe he's wrong?
Re: Turbo boost gauge testing
Mines quite smooth vac to boost ... obviously have a proper boost gauge .. it shouldn't bounce all over the place Ruth .
Re: Turbo boost gauge testing
Only thing to do is get a proper boost gauge installed. Very easy to do and will be very accurate
