Hi all,

New to the forum, have owned my Deli for a few weeks now.

I noticed quite quickly that the temperature gauge never seems to get any higher than 1/8th of the gauge (seems quite low based on previous cars).

It also has an issue where when cold, it occasionally stalls if we don't let it warm up enough.

After a Google, I found that the coolant sensor might be causing both of these issues so started investigating.

I ran a multimeter on the sensor itself, and it seems to change resistance as the engine warms. Going from roughly 3.77 to 0.5 as the engine warmed up. I don't know the exact temperature mapping but the changes seem reasonable.

I then dismantled the speedo cluster and put the multimeter on the gauge feed. At this point I received a reading of -1.47v at the same time the sensor gave me 0.87. maybe newbie but I guess I was expecting these values to match?

I was wondering if, and where the temp sensor feeds into the ECU so I can check the resistance there, to see if it is affecting the readings that the ECU uses.

A final question would be, does the coolant temp sensor feed into the ECU for engine timing etc. Or just the gauge for driver awareness. I'm thinking an easy fix would be to splice the cable quote close to the sensor and install an aftermarket digital gauge for me to track temperature.

Any support would be appreciated. 🙂

Thanks,
Tom

Temperature gauge, hardly move, most of our cars do that.

You do not say which engine you have.

2.8 Diesel - There is no ECU control to the engine.

Do the later S2 2.8s not have electronic metering or control of the injector pump,  using sensor imputs to an ECU?

The Temp Sensor for the ECU is the front one of the three in the top elbow of the engine. Item No.8 below:-




I have a 1999 model, by which time that was redundant:-




So in this Case the temp sensor on the head, adjacent to No.1 glowplug is used Item No.6 in the first photo above.
