M35 Factory Boost Gauge Repair.

[scotty nm35]

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.

"Literally a 2 minute fix"

Indeed.... and still working prefectly!

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.

Thanks mate

i wonder if the sender unit it used for the ECU as well as the gauge??

[scotty nm35]

I think the ecu sensor is the one before the blow off valve you can see in the top right of the pic.

Fix it yourself, its just a dab with the iron. Easy.

even my wgnc34 has a seperate one for ecu and gauge

[zei20l]

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.

really!

I am sure he is joking!

digital boost readout anyone?

[lachlanw]

yeah suppose it did sound sarcastic . but no i wasnt joking . car now has 4 map sensors . well 3 map and one boost as sensor for the ecu is out of the j pipe

Just did this to my Stagea and now works sweet..thanks everybody

I forgot to thank Scotty for this "how to", had mine repaired a year ago and has worked great ever since.

Thanks Scott.

No worries, can you come and solder mine, it's failed again. Lol.

Sorry, I have no knowledge in soldering, by "solder the three pins (at the top of pic)..." what do you mean by that?

[Daleo]

Look at the pic; the three pins, in a straight line at the very top of shot.

They are the ones that need resoldering.

re-solder the 3 pins in red color
