Dear All, I have searched for the questions I have with no luck so forgive me if it’s been covered. I have a suspension light on my 575 and the ride is now rock solid (apparently it’s a safety feature). Anyway, I’ve had someone plug the computer in and it has come up with an error 5203/C1203 Rh Rear Valve. They have advised that I need a new RH rear shock absorber. having inspected it, there doesn’t seem to be any leaks but of course there’s much more to the shock than just that.. So I’m stumped as I’m gobsmacked at how expensive the shock is (and I’m not sure how keen I am on a used one). Can anyone offer any advise, can they perhaps be refurbished? I believe it’s a Sachs part which everyone says in indestructible, but of course just my luck.. My car is an ‘03 575 with a FHP. Many Thanks in advance!
