Definitely needs more investigation. You must be the only one with a P38 EAS pump that can produce that much pressure.

Still got same job on wife's FL1, so will probably get polys for that !!

+1 on the compressor limit. Even with a gauge directly on the pump outlet, I've never seen more than 190psi. Hence why I asked if it was definitely a P38.

Yes they look reasonable to me. Voltage difference could either be differences in the sensor tolerances, or maybe slightly different supply voltage due to contact resistance in the connectors. You could try swapping the snsors over to see if the lower output moves to bank-A. Also give...

Yes they are tight. Old bushes are about 49.85mm dia. The arms are about 49.7mm internal, but are about 0.25,, bigger on one side measured with my vernier. New bushes are 50.2mm even after freezing overnight. So heated the arm ends a bit & got the bushes started in the vice. Then pushed...

Not sure how 1992 differs from 1995, but here's the later diagram with pin & colour info:

Not sure what the valve block seals will handle, but if it really if getting that high, check the pressure relief valve. It should blow off above 180psi.

Absolutely correct. There are loads of electrical noise sources in cars, hence why the HK Audio uses balanced audio connections & have each amplifier grounded. Most likely that car has corroded connectors in the footwells . . . where the balanced audio flows & it's randomly unbalanced ...

Yes. Test it first if you can. They are available, but make sure it's the closed above 140psi type. Many are the other way round. I'm guessing you're Estonian ? Put your town name or local region in your profile !!

+1 on that Keith. . . . it will be HEVAC motors, compressor clutch, condensor failure, SRS connector problems, heated seat failure, tired water pump, rusting steel brake lines, overheating fusebox, leaking rear-view mirror, etc, etc. ;)

Having got the arms & new bushes on the bench I tend to agree, but as I already have the new bushes will try them frozen first !!

Yes . . .. are you talking P38 ? For a P38 EAS It should run from zero until 140psi (or thereabouts). Then as pressure drops it starts again around 120psi. If pumping an empty system, it will stop periodically to put air into the airbags, but will resume until the system is up to pressure...

Yet more rubbish statements about cause & effect from you eh ? If your head unit is disconnect, and the speaker amps are still active, then somebody has been messing with the wiring. It will let you down at some point, wherever you happen to be.

You need to either Zip the file, or change the filename extension from "csv" to "txt" to upload it.

Standard bushes.

Before we digress too far (again) . . . . . @pete12345 even if you cannot open the file, upload the recording here, and we will take a look.

Removed both rear trailing arms & pressed out the knackered bushes today. That bit wasn't too bad. Replacement bushes are a fraction of a mm larger. Tried chamfering one end, but my press keeps pushing them to one side. Now got them in the freezer overnight & will heat up the arm...

Then they should call it CSCV !!

The file should open in either Notepad or Excel. Nanocom CSV format is not quite correct because BBS are still using semi-colons rather than commas to separate the variables.

Yes. BTW, as well as one of the connectors, it could also be a bulb failure in the cluster. There's two bulbs, & if one fails the other SRS light stays on.
