I have a 2008 RRS HSE which was modified by a previous owner to be on coil springs…after having driven around 2k km my mechanic suggested tightening all the suspensions … abt 50km after this was done I get the suspensions fault warning light on dash…. I switched car on and offf and fault disappeared. Now this has been recurring for the last 2 weeks with the fault appearing even whilst driving and esp after car is washed on driven in the rain. The drive of the car and engine performance have not ever been effected however have not tried changing terrain modes. Mechanic is having a look at it on Thursday and connecting to the OBD however any ideas would be appreciated as one of the reasons I was happy with the coil change over was to avoid the issues with the air suspension.
