2.3-16 oil pressure gauge
 

For a while now the oil pressure gauge in my 16 valve pegs upon turning the ignition on. I have isolated it to the gauge. does anyone recommend anyone who can repair these or have replacements? Do gauge clusters ( oil/water/vacuum/fuel ) from any of the other 190 models interchange.

Mine stays pegged at 3 bars idle or driving for about 10 minutes after start up! Are you sure this isn't the case?

The gauge pegs without the engine running, just have to turn the ignition to on.
