Just driving along and got the Suspension fault, max speed 30 and it dropped to low level.

These are the 2 faults, along with live values of calibration, and height sensor stuff.

I have no idea what the value should be.

Please help me

Not sure if useful or not, but the car does not drop at all, even after 2 weeks, so I dont think there is a leak.

Got your message..

Mine wasn't a leak either.. a lot of the problems started when my battery was on the way out.. the classic symptom is the amp crackling when the battery starts to drop.

I only experienced it once after I had replaced the front control arms. The suspense level sensor must have not liked it.. I changed the battery (yours night be fine) and then calibrated the height sensors using IId Tool. (It walks you through the procedure)

Hope this helps. Current:

Thank you.

Battery is good (only a month old), and the issue was happening before that as well as on Saturday.

It seems very intermittent, it happened last time about 3 months ago!

live values look normal, I think 1,3 is the minimum. All the U codes are electronic miscommunication codes. As far as I know a good suspension calibration with the IID tool will help you out. If not, a sensor might ask for a look in the carconfig check.
Bear in mind I'm a non tech and have spend hours with that sacred IID tool.

If not, have you tried a battery reset?

Thanks. I did a thorough calibration 2 moths ago, but I guess there is no harm in doing another.

try driving with off road screen on, you can then see all four wheel heights live on the screen. I had problematic height sensor which had correct voltage and height when stationary, but it would go crazy with values when driving, I tracked it with off road screen and replaced with new height sensor and now is all good  RR HSE 4.4 2006 LPG

Thank you.

I had to tow a large trailer and off road buggy today, 50km each way and there were no issues at all

I had the off road screen on and nothing unusual was happening, and also had the live values on the IID. Again, nothing untoward?

Something is amiss, as it has done it 3 or 4 times over the last 4 months.

Just cant find out what

I had the same problem with a brand new height sensor, tried everything, traced all the wiring and tested every connection. When you looked at the live value, it fluctuated VERY SLIGHTLY, sensor returned to dealer who replaced without argument, problem fixed 2010 3.6 TDV8
