Something weird happened today.

The stock boost gauge, after you start the car, starts to climb and goes all the way up.

Did some research and everyone says it's the map sensor or the little hose that goes into it. All are fine.

Car still boosts fine, power FC and evc6 both show boost readings fine.

Dead gauge? I tried checking all wires and earths but can't figure out what it could be.

Anyone had this before or knows wtf controls this dumb gauge?
I know it's not accurate but it's just annoying seeing it like that.

My gauge does the exact same thing, and I have Eboost2 and an aftermarket boost gauge tapped in, it's nothing irregular, just watch it over the next couple of days

I've had this car for 14 years and it's never happened. EVC has been in there for 3 years and before that AVC-R.

Ill keep an eye on it. Bloody weird ****. Searched around, seems others have had same issue but never say what it was or how they fixed it.
