- S320 CDI 2006. CLK350 sport 2006
Hi I’ve recently purchased a 2006 s320cdi with 40k miles. I believe the SPS is somewhere at fault. From a cold start steering is as it should be, light at low speeds and stiffer as speed increases. After 15mins or so it just stays stiff. I’ve run it through a star check and it identified Y10 SPS valve as being the culprit. I’ve changed this at no small cost and cleared codes. All seamed well for about an hour but now back as before. Strangely before It went heavy I got a whole load of warning messages ref ABS, traction control etc. After turning off and restarting the messages have gone but heavy steering remains. Any suggestions where to look next would be appreciated. Thanks
