OK,
Here's my story. A week ago I was driving my 2006 sprinter based Winnebago View motor home to get new shoes(tires, Tyres for all you Europeans). As I got of the exit on the lovely Garden State Parkway i heard this flapping noise under the hood( bonnet for you Britts!). at the same time every dash light you can imagine came on and the engine stopped. All of this was about 10 seconds in time. I coasted to the side of the road. I opened the hood and to my horror the wiring harness that goes over the fan shroud was shredded! I looked at the fan and saw a thin piece of rubber had wrapped around the fan an acted like a saw and cut the harness. This harness included wires for the O2 sensor and others. So being the electronics tech I am, I got some tape and commenced twisting and taping. Once I got done I removed the rubber from the fan. I was able to drive it home. I checked the serpentine belt and saw the outside rib of the belt had separated from the belt and caused the damage. The Dayco belt had only 20K miles on it along with new tensioner
and pulley's. I was only getting a 0032 generic code. Fixed the wires and re[laced the belt (not Dayco). Took it to a trusted MB mechanic with the right tools. Found all the wiring repairs I did were perfect. No sensor failures. When the wires were cut it caused ECU/problems. New ecu on its way. Who in the world routs a cable bundle where a fan issue could cause a failure like this? If you have an inline 5 cylinder look at the issue and just move the bundle. Easy to do. It may keep you from a failure a week before your long scheduled trip like I am going thru!
