Would a short it the wireing give me a high reading on the eas unlock program? ive swoped a confermd working sensor from the left to the right and the problem stays on the right side
I also droped it to the bumpstops and three wheels were giving readings between 50-60 and the suspect corner was reading 98 ???

Someone had a similar problem lately. Turned out to be wrong mounting bracket fitted.
 
Im starting to suspect damaged/shorted wireing but ive chased it back untill it goes into the floor and it looks ok
its ****ing me off now!!! Anyone fancy having a look? Theyll be a few quid in it for you!
 
Back to the beginning.
Your car was in a garage. Is it possible that a numpty has either bent a sensor mount with a jack or dropped the car onto something that has bent the mount? It would only take a small movement in the mount, amplified by the arm of the sensor, to give a wrong result.

Mmm thats somthing I havent checked
ive changed the sensor and didnt notice any damage to the mount but guess its worth another look

Don't forget that a high on one corner will give you a low on another corner, check them all for damage.
A short will not give a high resistance, a broken wire or corroded connector will.

I droped it to the bumpstops and was still geting a much higher reading on that corner

How do the sensor work? Ie.will a high resistance give a high or low number in eas unlock
I checked heights whilst it was unpluged to see if it maby had a short and was getting readings of 25 think that must be the default cos I got 25 from the other side when I unpluged that too

To be fair im still on a learning curve regarding the eas
And im rapidly running out of patience
im gona check for damage to the mount and check the wireing for shorts, resistance ect..
then im all out of ideas

You've obviously got the hang of reading the numbers from the ECU so that'll do for starters.
Put the car into access mode and write down the sensor readings.
Then up to normal and write down the readings.
Then, you've guessed it, into high and write down the readings.
Then look at what you've got. If all of the sensors change by roughly the same amount between the various heights then the sensor is working correctly but is starting from the wrong point, hence my suggestion that a sensor mounting has been 'nudged'. As you've swapped the sensors side for side then it can't be the sensor so it's either the mounting or the wiring.
 
ive been thinking today and i was wondering if hes "lifted the body" a few inch to do the break pipes! has he over streched the wires and broke them internaly?
of cause it only an idea and i have no idea how much he seperated the body from the chassis and as im working all week and its dark when im home i cant test this theory.
but is it plausable?
what route do the wires take to get to the ecu? and to double check,the eas ecu is under the pasenger seat?
i can see a rewire in my future. and to be honist im not bothered what it is thats wrong with it i just want to know so i can make a start fixing it
 
Right ive swoped sensors ive replaced a worn bag ive checked and even bypassd the existing wireing direct to ecu with no joy! im starting to think somehow the ecu itself has gone faulty?
as im still getting silly hight readings on the rear right and if anything the readings are getting farther away from were they should be as im now getting faults from it saying "rr sensor incorrect" and the height check it 50-60 points above the rest even when on all 4 bump stops
 
not git clued up on the ecu but could you reset the system somehow seems like you may have confused the system somehow so it resets to default if that makes sense

Only way you would get that is if you have wrong sensor or wrong mounting bracket. Unless the arm on the sensor is bent?

If you start feeling irregular vibration that comes and goes on P38, it could be the EAS compressor!
