2005 Volkswagen Touareg V8 with Air suspension. 2 Weeks ago, clunking noise developed in the front end and and my mechanic replaced the lower control arms and it didn't solve the clunking noise even though the lower control arms bushing were all really bad. This week, we changed out the upper control arms and while driving to the alignment shop, i noticed too much bouncing from the front end. At the traffic light, got out and found the front end was sitting too low and rear sitting at normal height and I started having the "fault running gear workshop" in the Cluster. Drove about 5-10 mins in that situation till I got home. I check the suspension and found out the passenger side's level sensor was not attached. The level sensor links were bad. Today, The mechanic created his own linkage(pic below) and NOW the suspension is not leveled. I get the "fault running gear workshop" about 1-2 minutes of driving every time I start/restart the car. One side sits a bit higher than the other side. He also checked the each suspension height and they were all different, not much tho.
The suspension takes longer to get from level 4 to level 5 height, so the compressor is working more. All this happened after replacing the upper control arms. When we first changed the lower control arms, none of this was happening.
I have read many threads saying it could be the battery, the compressor or leaks.
NOTE: Before doing any of this, the Touareg was flawless. Everything was working. The suspension was working fine without any issues. I have never had the "fault running rear workshop" since I have owned it. I have never had an issue with the battery. I have never had any light in the dash or cluster display.. This is all new and it was after replacing the upper control arms.
My mechanic has this fancy $3400 Bosch OTC 3896 diagnostic tool and he check the level control module and the level sensor code came up. He also checked the each suspension height and they were all different, not much tho.
The suspension still work, goes up and down.
Could it be my suspension level sensors? Any inputs, thoughts or ideas are appreciated! Thank you!
