You come highly recommend, so I hope you might be able to help me with the following problem.. first up, Its a 1997 E39 540iA.
After doing a pixel repair on an E39 dash cluster, I seemed to have caused a problem with the temp gauge.
When the car is off, the needle sits in the normal home position. Not too low, not too high - just as it normally would. No problem so far.
When the car is dead cold, Key in Pos 2, (not started) the temp needle swings to just passed half way ( slighty more than normal operating temp position)
When the car is up to normal operating temp, the needle sits slightly more than the cold condition described previously (a bit more than half way).
When the Cluster Test (Test-02) is performed, the needle starts at Zero, and swings to about 3/4 way, then back again. Not all the way into the red like it usually would.
The needle was NOT removed or adjusted for the pixel repair.
Its a 1997 540iA.
- Could it be some kind of calibration issue? Can the gague/cluster be calibrated?
- Could it be an error code on the cluster thats causing it to act this way? Maybe caused by unplugging the dash seveal times during testing the pixels?
- Or is it the motor on the cluster thats now fauty?
I find it strange that the needle moves to passed half way when the car is cold. It is obviously getting some signal to tell it to move to a postion. Its just not the right position!
I had experienced some craziness in my cluster recently, and the dealer wants me to replace the whole thing for $1,300. I am in hope that at your convenience that you can give me some insights about some of the issues you might have experienced before with your car and how you resolved them.
