Nope thats it, not sure if I want to fix my self, want to get quote for fix and maybe even possible esl by pass fix?

Hi! My name is \*\*\*\*\* \*\*\*\*\* I will be able to assist you. I’m sorry that you’re having trouble with your vehicle. Don’t worry though, we’ll be able to figure this out. Thank you for taking the time to let us help you out with this problem and hopefully we can sort it out quickly. Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. The most common problem for this issue is a low battery so I would check that first. It should have 12.5 volts. If you don't have a voltmeter then you can try to jump start it. If the battery is good then you'll need to connect a scan tool to get the codes from the module. Let me know what the codes are and I can pinpoint a specific fault. My goal is to give you the best service possible and to help you. If you have any questions or concerns, please don’t hesitate to let me know. If I’m not online at the time, I will respond ASAP when I get back.

Hi Yes I tried to jump start. Doesn't even try to turn at allI have a odbii module I can send you the codes tonight when I get home. I didn't really even think about that, but yeah I probably should to make sure. I'm pretty sure it is the steering wheel lock causing it not to start. I have been having a couple of episodes the last few months where I have to move the steering wheel a for it to engage and then it starts. But this time no dice!
Automotive Expert
Ok sounds good. If your scan tool can connect to the steering module then it will give you some codes.

ok so here are the codes 0140, 0174, 0128, 0497, 0171
Automotive Expert
Ok those are engine codes and wouldn't cause the problem you are having. You'll need to scan the steering module for codes.

Okay, how do I do that?I thought it odbii would scan everything?
Automotive Expert
You would use a scan tool that plugs up to OBD plug but you'll need a special scan tool to access the steering.

Automotive Expert
No. That's only for the check engine light. The cheapest scan tool I am aware of that can do this testing is about $3500.

Oh wow..what can I do next. Will a esl by pass module work on my c class
Automotive Expert
You'll need to get this to a repair shop. A diagnostic would cost less than any part you can buy to fix it. It may just need to be reset.

But if it was the steering wheel lock mechanism if that needed to be replaced how much is that for repairCan you be or can this service come out and take a look at it and read the codes. I'm just trying to figure out what to do before I get it towed anywhere cuz once I tow it somewhere then it's it's hard to go anywhere else.
Automotive Expert
You can search online for a mobile mechanic to come out and test it for you.
