Couple problem areas I recall, there was a bolt that was to long/short in the front suspension that caused the car to pull to the right that I belief there was a TSB for (I think this may have been corrected before your car was built). The sensotronic brakes were an issue. Those were the two main issues I recall on my E500. It was a beautiful car but it did have some probs. Hope yours is well sorted. Love to have another one myself.
