My super-cheap Mercedes E420 suffers from the same condition that other Benz's do. It's a transmission that won't shift gears. Most people usually just assume the transmission is bad and sell the car super-cheap! That's not good for the owner, but it's great for the buyer IF you know how easy it is to fix.
In this video, I'll show you how to get out of Mercedes limp mode and get your Benz back on the road. There's a second OBD port few people know about, but necessary to fix the problem. I'll also show you how to replace a bad Mercedes blower motor and how to replace a bad Mercedes instrument cluster!
