Hi everyone,

The turbo boost readout on my tach is stuck at 0.7

The gauge was recently cleaned and given a new lens at PA Speedometer and then re-installed. I have ruled out the possibility that PA Speedo did anything b/c it was just a new lens and a cleaning.

Any ideas?

Thanks!

are you sure the wire at the intercooler are in right place?
if there is wrong readout it often ends there...

A few years ago my readout also became stuck at 0.1 bar. And it turned out to be the boost sensor connector at the intercooler (driver side I think?)

ianbsears

Thanks for the ideas. You were both right. It was the boost pressure sending unit on the intercooler. The wires were on but the unit had failed. When the wires were removed the readout fell to 0 and when reconnected went straight back to 0.7. New one is on order!

The factory display will only show a max of .7 bar so your display and boost sensor are working as designed.

@Metal Guru - yes on 0.7 being top but it was stuck there.....at idle and thru the rev range

lol dumb question how do i switch the display to see the boost bar? Its always on mpH ..

bweSteve

the staulk on your steering wheel column (left side). pull it back towards you to change the various views

Lol,... for 17 yrs now, my wife & I are constantly changing it back & forth ... she likes to see MPH,... I like to see the boost level ... we joke about it all the time

Yup. Things are happening so fast that I'm afraid I'll drive into the back of a garbage truck or something.
With my Innovate PSB-1, I leave it set to peak boost so I can review it safely at a stoplight.

Convert your clock into a manual boost gauge which allows you to monitor both boost and vacuum levels. The right dial starting 1:13 is what I put in my 3TT.

Nice video, Do you instructions on the modification to the clock and the parts needed?
