Update, now in the Poo!!!

So to summarise.

Suspension has always worked in all heights quickley and well. (Up to yesterday!! lol!)

However, I noticed the front front kept dipping slightly. Hawkeye, said a RHF sensor fault.

So, I removed the RHF sensor and cleaned it, and did a test on an avo meter. The needle did drop off rather suddenly as I moved the sensor arm through its normal movement. I tested the movement where the arm does not usually move, and the needle movement was good on the avo.

I decided, as advised, to swop with the LHF sensor.

I checked the LHF sensor, this arm moved freely, and the avo showed a smooth needle movement as I moved the sensor arm. (Right though 180 in fact)

All good so far.....

I swop the arms over. All went well, no stuck bolts/nuts etc.


Problem:

Car won't rise correctly.....

"RHS Sensor fault" has now gone from Hawkeye, but a new fault keeps popping up....."Car Has Moved"!!!

Occasionally the car will lift a bit, but as soon as I enter the "exit" mode (lowest), the car bumps back to base height.

I have cleared the faults several times but the "Car Has Moved" fault comes back.

When I switch off and start the engine, instead of rising to the usual "-" mode when I move, the car actually tries to rise to "wading", the highest, which is weird!!!


I don't understand, what is wrong, I only swopped the sensors over, which seems to be a good thing to do!!!!

Help!!!

Rachel :wtf:​
 
You will need to recalibrate the heights to allow for changed sensor readings. Car has moved means nothing it just mean the suspension has dropped since last use.

Meanwhile put the sensors back where they came from and you should be able to use your car until Sir Datatek comes to your rescue.

Wise words! I have another car, the swop killed the sensor fault, so may wait and calibrate. The weather is a bit yuk, got soaked swopping them. Not sure I want to get soaked. However, if the calibration fails, will swop them back then :)
 
Buying new is best. 2nd hand is fine if you can check it works. All down to budget of course. I bought a second hand valve block for the eas (£30) so I could remove my failed unit and rebuild it with new o rings etc. The second hand unit worked fine and is in fact still in the motor. You takes yer chances.
If a used sensor works then great, though probably will need replacing in the not too distant.:cool:
 
Another update...

The Car is now going up and down ok (still needs a calibrate), Hawkeye can send a default set of values to system, it tells you to get the proper ones done, which I will.

I suspect, that when I soaked the electrical contacts with contact cleaner, they had not dried out properly.

I don't lose height over night (no bag leaks), but I can hear the pump click on and off. I hoped that the sensor swop would fix that, as I thought the dodgy sensor was triggering this!! Will dig deeper!!!

The sensors can be swapped from side. Early EAS Sensors can be swapped from side to side without any wiring change. The later sensors, the wiring has to be reveresd. Center pin stays the same but the outside pins swap positions. :)

Are you sure about that? Think it maybe the other way round. Later sensors can be fitted either side hence only one part number for front and one for rear. Early ones are handed and cannot be swapped over without mods. Four separate part numbers.

That's correct the later ones do only have The one part number for the front and one part number for the rears :brick:

Nothing to do with Hawkeye. If a setting is outside the set parameters for any particular height the ECU defaults to a preset.
 
Two points, IMO second hand sensors are a waste of time, they will be at the end of their working life. Secondly, I have never thought swapping the sensors side to side is a good idea either except for elimination, having opened a sensor up, the worn area of the track is too close to the centre to be a viable long term solution.
Rachel, I have PM'd you.
