I just replaced the left front air-strut on my 2000 s500 yesterday (7-13-10). Now, my steering is a little stiff, the ABS light and ESP stays on and is also saying Airmatic visit workshop. The shop said they checked everything that had to do with the AIRMATIC and there was no leak. The car drives fine besides the steering wheel being a little stiff. What can I do to get the lights off?
