[urq] Oil temp falling on -88 MB quattro

[Michael Hopton]

Johan,
It is probably more likely the sender (at the front of the
oil pan), the wiring between the sender and the gauge. Or
the digital display. You can measure the resistance of the 
sender when it is working and when it stops. Also does the
voltage display change. Another possibility is a bad ground
for the display.

cheers, Mike

Subject: [urq] Oil temp falling on -88 MB quattro

hope someone can help me with this, I'm a pretty new urq owner so I need
all the help I can get.

The quattro has done this a few times the last two months. At first the
oil temp rises normally to about 100-110 degrees celsius. then all of a
sudden when I drove, the reading on the digital display fell down to 60
degrees (the lowest reading). When I drove a further 30 minutes the temp
jumped again up to the normal 120-130 degrees on highway.

Does the urq have a thermostat on the oil cooler? Could the problem be
caused by this? If there is a thermostat, where is it located?

Rgds,

Helsinki, Finland
