Guys, I've done a lot of searching, but still can't understand where the failure is.
LC 2004, with VGRS and AHC.
Couple of weeks ago I realised, that the car drives very rough. That's not my daily driver, so maybe the issue progressed longer ago and I just didn't pay attention to it.
Anyway, it drives like it has no suspension at all, you can feel each crack in the asphalt. My HJ60 with leaf springs drives better!
First of all I tried the suspension switch - changing to Sport makes it even worse, so at least the switch works
Checked the number of marks while going from L to H - about 12, looks like everything is fine here too.
Getting from L to N takes about 20 seconds, N to H - 15.
I took the Techstream, saw that the FR sensor was pointing to 19mm in the N position (and both FL and Rear close to 0).
Checked the pressures, nothing unexpected - front 6.5, rear was 8, but I didn't pull off the temp.sensor.
Corrected the front right sensor, everything is fine, but the ride is still rough.
Luckily I had 2.5L of AHC fluid left from the previous fluid replacement a year ago - so I've replaced the fluid like it's written by PADDO. The fluid was dirty and dark (replaced a year ago!).
Also, there was a lot of air in the pressure accumulator.
Still the same situation, did not get better at all.
I don't have the screenshot of the system after the sensor correction, just the one before - so pls ignore the 19mm, it's now -0.2mm
The front pressure is now 6.1, rear 7.5
Steering angle -146deg in the picture looks suspicious to me, because the car drives straight and the steering wheel is straight. Did the VGRS calibration several times - no change there.
Any ideas where to start from?
