R34 Mfd Boost Gauge Reading 0.00 All The Time

[full_stick]

Last night I was driving quite aggressively home, going through the gears and I noticed that the boost gauge reading was stuck on 0.00. Please keep in mind that this is a digital meter so the needle isn't physically stuck or anything like that. Normally when off boost the MFD will have a negative reading so I had a look at my blitz iColor as that too has a boost gauge and surprisingly it too was stuck at 0.00.

Don't want to drive around with no gauge as I've only just had the turbos changed, literally last week, and want to ensure they're running correct boost levels. Any ideas guys?

One of two things.

1. Sensor/sender is broken

2. The VAC line has come off

Most likely #2, and if you've just had the turbo's swapped even more-so

Thanks heaps for that mate! I'm far from being a mechanic but am starting to do a few things here and there myself. Are you able to give me a quick description as to where I'd find the vac hoses in the engine bay.

From my very limited mechanical knowledge they're located on the drivers side under the strut bar is that correct?

Mechanic also mounted the solenoid unit on the passenger side near the pods and I checked the solenoid unit and both hoses seemed to be on fine but I need to follow them down to the their end so I can check that side as well.

I don't really understand how a ebc works in terms of vac hoses/air flow so I'm a little confused.

I'm pretty sure it is a vac line as i was boosting it pretty hard when it happened so it sounds logical to me, the internet mechanic haha.

You need to have a VAC line connected to the MFD sender mate - not just the EBC.

It sounds to me like your mech has used the MFD line as the feed for the EBC perhaps.

Vac line for sure

happened to me

easy fix ...
