Okay thank you .
Okay its going into default position. you need to check for malfunction codes as said this is the only way to check.
Do you have the tools to check for this ?
Level is to high but should be okay and not be the problem .
If he has the correct scan tool to check the system then he will see all that is needed to check .
Any issue let me know .
Did you bleed the system .
Sensor data has to be compared with vehicle height.
Will get back to you today when i get into work and check the manual for you .
Why did you replace the front Accumulators ,for this same problem .
Okay good this is correct, when the suspension get rock hard the Accumulators are bad and is normal to replace all four then bleed the system, expensive item i know but better to replace all four as the membrane inside collapse..
But as said will get back to you later on in the day with more information .
Have you made any headway ..
Attached is the suspension height settings .
Okay good .
Please keep me updated .
No problem .
This is why i sent you the height adjustment ,
But if before thw accumulator failed it was working, then should still be good.
The different measurement are because the ride height is not completing it travel .
Way out you will need to check and adjust the front as shown in the adjustment sheets i sent .
Strange that this should happen ,get the mechanic to recheck this on firm level ground and must make sure all tires are the same and
with the same air pressure .
Its going into default as something is stopping it going into H due to the system thinking its going to high .
Recheck for codes .
