Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
HiCustomer can you tell if the clicks you are hearing are coming from the starter?
Ok, the only correct way to test for the problem is to perform some voltage tests at the starter or the starter relay (pictured) can be bypassed to see if the starter operates. It sounds like you have a bad starter. The loud click being the starter solenoid. Due to the tip starting system that you have sometimes the teeth on the flywheel can be lubricated and it cures the problem. If this problem started only after the battery was replaced I would clean and reheck my cable connections. A new (remanufactured) starter runs in the $350.00 range. Labor to test the circuit and replace the starter would be about 3 hours. If you'd like to know how to bypass the starter relay I can help you. You will need a fused jumper wire. Let me know if you have any questions.
Thank you for your response. Is it possible that I could have a starter relay problem only, and is there any way to check that out before I have to take it in for a voltage test?
Also, how do I lubricate the flywheel? Thanks
Yes it is possible that it's only a bad relay. You can bypass the relay for testing but you'll need a fused jumper wire. If you pick up an inline 10 amp fuse holder at an auto parts store it makes a good jumper. You can crimp the appropriate ends on the jumper to plug into the relay box. The starter needs to be removed in order to lubricate the teeth of the flywheel. If you want to bypass the relay let me know and I'll look up which terminals we need to jump. FYI, if the loud click is coming from the starter then your relay is ok.
