Hi guys,

ok so I have a 2008 C350 mercedes. The last week the car starting giving me issues to start. I took it to Mercedes today and the guy did se emy issue. He said its either the EIS of steering lock issue. Both being very expensive.

I did find this on the forum:

So I was hoping they will replace the EIS for free but they can't even find this campaign in South Africa. This is a video I just ook:

So if its working you can hear something "grabbing" the key. The above sound is when it doesn't work. The sound is if its trying to move something but doesn't.

My EIS and steering lock went out a few months ago. Even in the US there is no open recall on this.

I was originally quoted $1,300 to fix it but since I bought an extended warranty it was bumped down to $350.

This is definitely something you will want fixed as it can leave you completely dead in the water.

Yea car is already down on starting just every few hours Soooo sad and its soooo expensive I've been calling every Mercedes place I can to try and get them to fix it for free but tomorrow is a public holiday so will have to wait till next week. Don't want to fork out R15 000.

I also just found this:

Thats definitely your steering lock going bad or went bad. find someone locally to reprogram a emulator this way no more steering lock failure. Or you can try fixing the motor inside the steering. I never had luck changing motor, i just put a emulator and call it a day.

How can you tell? I was thinking its the EIS because if I get into the car and close the door and then insert the key my steering wheel changes the position and the cluster lights comes on. Then there's no crank and the windows doesn't work. But with my car if I open the door I don't get an error saying my key is still in the ignition. So if it is a steering lock issue, wouldn't the car then warn me about the key? Or perhaps a 2008 doesn't have this feature? Or is it simply just the EIS then?

I just had the same issue with my C300 yesterday. Had it towed to an Indy shop near me. My mechanic called this morning and told me he had no issues at all. Hoping that this was just a fluke.

While I would hope for the best, I would plan to have to replace it sometime soon....it may be an intermittent problem for a while but it will eventually just die...don't leave home with out your cell phone

Ok so just to leave feedback. I did fix this a while back It was the steering lock and cost came to R7000 (for people in South Africa.) Still loving the car but really hope nothing else gives in coz Merc ain't cheap

Where did you get the emulator? How much was it? was it hard to install or just a few wires? I was thinking of taking the motor apart and replacing it. If the steering lock motor is failing how would putting an emulator help? sorry for all the questions!

i would also be interested in the answers to those questions. Anybody have any input.

My advice is don't use emulator fix it properly
