Customer Question

X Reg. C240. Intermittant starting problem. does require 6 or 7 attempts before firing. It seems to identify that the key is in position, when it is not. and warns to remove key because auto lights are on. Progressively getting worse. Batteries in keys seem OK

Hello,Such symptoms are caused by failing electronic ignition switch. This can be confirmed with Star, but only dealers will be able to order and teach the new ignition switch to your car. Ignition switches and keys are sold only to authorized MB dealer workshops.Best Regards,Stan
