Hi all,

My rear left always stays around 20mm higher than the rest of the car. I have the iid tool and even when I recalibrate the suspension within 10 mins of driving it returns to being around 20mm higher again.
The only fault that shows up is C1A20-64

Could be a faulty sensor. Coupled with that error I’d also look at removing the valve blocks and cleaning them and possibly rebuilding them (new o rings).

Can the IID tool operate individual components of the suspension system? In JLR-SDD you can operate each valve, the compressor, raise or lower each strut, etc. makes it a little easier to diagnose problems. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

thanks for your reply.

I was thinking possible a height sensor but wasn't sure.

I'm not sure regarding if the IID tool can operate individual components but I'll give it a try 👍
