M35 Factory Boost Gauge Repair.


Recommended Posts

I found the issue with the factory boost gauge bouncing or not working at all. If you open the sender unit, dont remove the board, just solder the three pins (at the top of pic) that run to the plug underneath and youre done. Literally a 2 minute fix.

So is that the issue then - just a bad contact on some of the solder points?

Excuse my newbie-ness, but where is this sender unit located? I have done a bit of soldering in high school but my brother-in-law is an electronics tech so I'll get him to do the actual fix up...

Is it easy to get to? or is it a case of 30 mins getting to the part, and 2 minutes to fix it...?

Steve, it is the black, roundish sensor that sits to the left of the rubber bend part of the intercooler pipe

Just unscrew from bracket, remove bottom hose and pop the tabs on each of the four sides.

That is him, in the middle.

its funny, RX and ARX dont have boost gauges yet they still have the sensor lol

is it a 0-5v sensor? might be able to use that instead of installing another one for an aftermarket gauge.
