Since they dosen�t have the car it�s a bit hard for the shop to test the oil pressure instrument cluster, so I�m wondering if its possible to insert a analog signal to test just the Oil Pressure Gauge?

However, I would like to know if it�s possible to insert a variable voltage signal between pin 9 and 24 on plug 1 (blue) to test the oil pressure when the instrument cluster is open and on the table.

Can they just use a 0-12V power supply (or is it a Milli-amp signal..?)on these two pins to test the oil pressure gauge?

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

After replacing the gauge faces, the Oil Pressure needle is dead. (When the the needle was pulled it came off with the "shaft" as well...). All this is done by a speedometer-workshop and it�s located far from me so I have to send the instrument cluster back. Since they dosen�t have the car it�s a bit hard for the shop to test the oil pressure instrument cluster, so I�m wondering if its possible to insert a analog signal to test just the Oil Pressure Gauge? As far as I can see from the work shop electrical schematics the is the oil pressure signal coming in on plug 1 (blue) pin 9, and the analogue ground is connected to plug 1 pin 24. Can they just use a 0-12V power supply (or is it a Milli-amp signal..?)on these two pins to test the oil pressure gauge? All help appreciated

POST 2 / ORIGINAL POSTEROriginal post

Update: It�s not completely "dead", it raises up to approx. 0.7 bar. When i turn of the engine, it stays at 0,7 bar until I�m knocking on the instrument with my fingers so it looks like it get stuck. However, I would like to know if it�s possible to insert a variable voltage signal between pin 9 and 24 on plug 1 (blue) to test the oil pressure when the instrument cluster is open and on the table.

Have you tested the output from the sending unit? Garbage in, garbage out.

POST 4 / ORIGINAL POSTEROriginal post

Haven�t done that, but it was working perfectly fine before the instrument cluster was disconnected and sent to the Speedo-workshop. Can�t imagine that anything should happen with the Oil Pressure Sensor when the car has been in the garage all the time...

Very simple to test. Check for current at sending unit when key is on. If current is there, jumping both wires will deliver current to the gauge.

This is a source reference. Confirm exact model applicability in the original material.
