My wife was driving her 190e and it suddenly shut down. Car was towed to a shop where they spents weeks trying to determine the problem. They were ready to put on a new fuel distributor on when I said "woe Nelly!" and had the care towed home. I checked all the electric connections for the fuel injection system and found the wire to the temperature plug at the front driver side of the cylinder head was broken. Replaced the line. Also had to replace the O2 sensor because it had become fouled (from overly rich mixture??) and car ran fine since. It sould have been a 50 cent repair. From now on, if a car breaks down it will be towed home and I will review the manual and this website and attempt a DIY repair before I send it to another tech.
