Today my wives 1993 400sel went into "limp home"mode. The car is a one owner with 79k on it. Always stored in a heated/ac garage. The main problem is no warning lights are on in the dash pod,no ASR light ,no warning lights at all it looks all normal. I have tried to reset the car by turning off and restarting. but it stays in the LH mode. I have disconected the battery hoping it would reset, but it stays in the LH mode. The question is why is the car in the LH mode and why are there no indicator/warning lights on.
Thanks for any help.
