Hello Guys,

I have C 220, diesel engine, and I got a msg asking to update the bluetec software. Do I have to update it, and if not what will happen and how can I get the software.

Thanks for your assistance.

 

I'd be careful, the car may catch on fire. You could be driving 50 mph and your engine might fall off.

But all seriousness, I don't see why you would even consider not updating. I believe you can take it to dealership or search around on google.
