According the EMH Manual the resistance of the MAT sensor at 20 degC is around 3400 Ohm. So your measured value sounds right. Be aware that the sensor resistance is not lineair with the temperature.

Does anybody know the paint code (color) for the OZ rims used on a 1990 SE? Searching on the forum revealed that the question has been asked before but I could not find an answer. I hope that somebody knows the answer.

The resistance values for the various MAT sensor temperatures is also given in the EMH manual.

NO Heat There is a spring loaded pin, You need to press (there is a small hole on one side) it, after which the steel part can slide of the aluminium part. Attached a manual for overhauling the bendix rear brakes. Bendix Overhaul ex Matra club.pdf

@mike_sekinger as promised, took the wheel off, hope you have enough info with the below pictures. As you can see there is a difference in the sensor, my sensor connector is centered whereas "Tom's" sensor seems to be offset. Looks like my sensor is centered in the teardrop footprint. The outside of the connector securing clip (yelow line) is in line with the inside of the web. The bottom of the securing clip sits 15 mm above the machined Hub Carrier VSS flat.

Looks like my vss is different. At the moment I’m away so maybe Sunday evening late or Monday.

The owner doesn't know where his/her car is?????? 😵 Stolen??????

I assume we will get an invoice? I haven't seen it yet.

Thx Ian, it is not in Service Notes for the SE but I found it in the S4 manual. (forgot about that).

Anybody know the toe angle change per mm shim alteration? I want to take out the guess work as much as possible. According my calculations 1 mm shim alteration equals about 0.1 deg toe angle change.

The primary injectors are Peak and Hold injectors ie a larger current is used for opening and after reaching the opening current the ECU (which measures the injectorpai current) throttles the current back. As the injectors are paired (1&4 and 2&3) the current through an injector pair is evenly distibuted between the 2 injectors if they are of equal resistance. If not then one injector gets more current then the other causing different opening times or not (fully) opening of an injector.

It does not happen in my esprit (mechanical ODO) It is more like a suggestion. The picture above and the posting that when it works it displays the right numbers and my experience with similar failures on LCD displays make a strong case with failing contacts. The LCD displays in general are connected to the PCB by solder contacts or by means of rubber conductive strips which are clamped between the display and the PCB. Fixing the bad solderjoints is not so difficult. If the display uses the "strips" one has to remove in general a (brittle) plastic holder and then the contact points on the pcb can be cleaned with IPA. Another problem that can occur is that the plastic holder for the display is a little bit out of shape and does not apply evenly distibuted pressure / force along the row(s) of contacts. In both cases you have to open the speedo

Bad contacts of the LCD inside the speedo.

For my SE Pink for the LH mounting Blue for the RH mounting

Your efforts / time / etc in this project are highly appreciated.

For my SE I also have to remove the map pocket.

Two hydraulic connections?

In the AC request circuit there is also a low pressure switch. If the switch behaves erratically (due to faulty switch (connections) or just enough pressure in the system) the AC will be switched ON - OFF - On etc (there is some debounce in the software of the ECU). This can explain the erratic behaviour of the Idle speed, as the ECU wants to set the idle speed for when the AC is ON / OFF

The amount of fluid which has to travel trough the pipe is only dictated by the bore of the master cylinder and the (pedal) stroke. and is independent of the volume of the pipe. A smaller pipe is a little more restrictive flow wise. Why not just make up a mockup (won't brake the bank) and see if it works?

Hi Tom, @tomcattom You could have used the already present oil temp sensor on the left side of the oil gallery cover just under the turbo oil feed line, with the benefit of it sitting in the oil flow.

If all the testing etc goes right I'm in for my SE @mike_sekinger

😪😡 I have to work that day. Maybe I can find somebody who wants to swap / exchange that day. Keeping my fingers crossed.
