Rear of car very low after 4 days of non-use

[Slabber]

Hi All

For the second time I've noticed that after being sat in the garage and not used for about 4 days the rear of my (new to me) car is very low on both sides. After the first time VCDS reported 403200 - Function Shut-Off Active > C10C8 00 [008] in Level Control which I cleared. However having driven the car tonight and then rescanned that fault code hasn't returned.

I've Googled for that code and seen various threads where it appears with other fault codes but nothing that matches my situation. Any thoughts on possible causes? Thanks!

Cheers - Graham
