Temp gauge on my '87 316 E30 BMW was jiggling. I spent a lot of time on removing it, cleaning and soldering contacts (soldering contacts helped but when fully warmed up needle on gauge was not vertical), so I decided to change complete instrument cluster.
This "new" one (from the wrecks) has fuel consumption gauge, and 318 was written on it. How does that work? What sort of sending unit does it use? Is it only for fuel injected engines? I have carburetor so can I add sensor somewhere (I guess it is some vacuum measuring sensor) and make some use of that gauge?
When I start engine now needle just goes from left to right.
