Suspension - Replaced airbags and car sitting low on left hand side

[r7ehw]

Thanks.

Correct Group 4 says reg position not learned.

Car sitting at approximate heights as you describe.

Car is struggling to adjust I don't think it is trying when it says wait.

Question:

When I undertake adaptation it says wait in first box. should I wait before entering value and pressing test or do I just go through press test and then save or should I wait a couple of mins before going through the sequence?
Sounds like it may be beneficial to deflate driver side rear bag as that is so far off where it should be. If I deflate would be interesting to see if the system tries to put it back to where it was.

Will try your jacking method

While it says wait the car adjusts to level 2, (level sensor readings all zero)

In your case, its lost zero, So start adaption, jack all 4 corners to 402mm each wheel centre to top of arch, then go to next group and type, 402..and so on.

While it says wait you only get 2 mins to get car to 402, so have car ready on jacks a little low, before starting adaption process. we just need it to store a rough level, then we can "tweak it" if the system works after storing the calibration.

Okay. Progress.

drained air from full rear bag. replaced wheel switched on car and air system worked lifting car on all corners. Cleared faults and undertook 402 procedure using approximate values. end result was car was adjusting during the process and moved back to level it was earlier on pretty much. Not ideal but confidence in that it is working.

Checked measuring block group 4 and get the following - -14, 16, -15, 69

That rear shock is really throwing the car off.

I have tried repeating 402 procedure but can't get the system to let me in, saying system dropped I believe I have to switch off and give some time before I try again.

Will report back when I have rerun this procedure.

ok

Go to measuring blocks group 4, lift each corner and make sure all values move in a positive direction, if one goes negative sensor is fitted backwards.

also that high 69 value in the last box, that is rear left, is that not your lowest corner? Make sure during the adaption you enter values front left, front right, rear right, rear left in that order.

the 69 value is drivers side (UK Car) rear, so is 4th corner right.

Just to check I had that this was the order:-

01=Left Front
02=Right Front
03=Left Rear
04=Right Rear

Right being the drivers side of the car.

This is slightly at odds with your last paragraph

[r7ehw]

I have used jacks to level out the car best I could with the exception of the high corner which I left as it was, sitting high.

I have then run the calibration exercise. with the following heights being shown in group 4 for the following ride heights:-

height 2: -21,19,-24,47
height 3: 2, 44, 16, 64
height 4: 17, 61, -6, 85

This shows the car is going up and this process operated without issues.

When I come to lower the car the 4th corner will not drop. eventually I get it to level 2 with switching on and off the ignition twice since dash light comes on.

final height 2 as it is now is showing as -26, 31, -13, 89

clearly the car is so out at corner 4 it is lifting the car accross corners 2 and 3.

I now have error 01400 sus level contol 08-10 control limit surpassed. Intermittent.

Its almost like the release valve isn't working properly, or the communication with it?

I think it eliminates wrongly fitted sensors too but I feel there is an issue which needs fixing before focus can be on leveling the car further.

Really appreciating your input here Andy.

Hi, ok, my apologies I was mixing you up, you are correct,
01=Left Front
02=Right Front
03=Left Rear
04=Right Rear

Ok rear left level sensor doesn't make sense,:

height 2: -21,19,-24,47
height 3: 2, 44, 16, 64
height 4: 17, 61, -6, 85

In height 3, it goes to +16 or is this a typo? As height 4 it goes back to -4, if these values are correct, this points to a bad level sensor on that corner,

Watch group 4, 3rd window, jack that corner up checking if values jump around or climb steadily positive?

If they jump around its a suspect sensor.

Let us know what you find.

Best regards

Sorry correct level3 rear left should read -16.

height 2: -21,19,-24,47
height 3: 2, 44, -16, 64
height 4: 17, 61, -6, 85

Should I now disregard your comment. Where from here, particularly regarding the rear right which will not deflate?

[bagpipingandy]

I think the valve is opening ok as it should lift 25mm each level, and all 4 corners lift, the rear left is still a bit suspect only moving 8-10mm each time, that could be coming from the good right rear lifting the car, if you remove the airline to the rear left corner and ask it to lift do you get air coming out the hose?

can you run the adaption to lower the 2 RH corners, does it complete? If not only change 10mm at a time, it sometimes doesn't like huge alterations.

Is this car new to you? How did the level get so unlevel? Have you done a lot of calibrations?

Best regards
