“Rat Race” – Mercedes Wiring Harness Repair – Damaged By Rodents

AMC Tech Case - Rat Race This Mercedes E350 came in with a no start condition, radio inoperative, and a host of other electrical issues. We weren't the first to work on this vehicle, it was clear that many hands had been in here before, and apparently given up without success. Cause The highly skilled AMC Service Techs Kyle and Scotty collaborated, were able to trace the fault, after a good day of diagnostics, and interior disassembly, to a electrical wiring and fiber optic cable issue, located inside one of the wire chases. As these chases run from the front [...]

AMC Service Tip – Replacing Stuck or Blind Hole Bearing Races

Problem Removing Stuck Bearing Races Tapered roller bearings are commonly found in wheel bearings, transmission, differentials, and other automotive systems. They consist of two parts, the bearing cone with the roller bearing, and a “race”, which is the highly polished and hardened surface on which the bearing rides. The race is pressed into the part or casting and the roller bearing installed on top of it. So let’s say you have a bearing race (transmission, wheel, differential or other) in a “blind” hole that you need to replace. By “blind” we mean you can’t access it from the back of the [...]

Mercedes 300SDL – Fault In Climate Control System

Car presented with Incorrect air flow out the heat/ac vents. Upon inspection we discovered that a previous servicing facility had worked on the vehicle and left the ACC system in total disarray. Vacuum lines were disconnected, flaps were wire tied closed, actuators were disabled, vacuum manifolds were plugged, in short, the ACC air direction system was non-functional. This required removal of the dash pad and center console to fully inspect and access what was needed to make the system operational once again. Subsequently upon removal we found broken flaps, damaged cable actuators and stripped gears. This is a major undertaking, [...]

VW Passat V6 – Engine Oil Sludge – Incorrect Oil Grade Used

Engine oil sludge does not just affect Saabs, take at look at the oil pan and lower engine on this VW Passat. That black gooey substance is not tar, but engine oil sludge. Unfortunately the car was switched over to a full synthetic engine oil too late in its life, for the first three years it was run on a conventional oil, you can see the results. It is cheap insurance to always use a fully synthetic engine oil on all European autos newer than 1999. We use Castrol Syntec in our workshop, it is the factory fill on many [...]

Mercedes 300SL – Rodent Damage to ABS Wiring

With only 22,000 miles, rodent damage on the ABS rear wheel speed sensor data cables. Somehow a mouse found its way inside the car, under the seat, under the carpet, under the foam padding, and into the rear wiring harness conduit for a quick snack. Required extensive work to diagnose and then removal of the passenger seat and carpeting to service.

Audi A6 Quattro 2.8 V6 – Scheduled Timing Belt Service

Audi/VW timing belt replacement is a bit of a project as it requires the removal of the front nose of car. When replacing the timing belt it is critical to also replace the engine water pump and thermostat as they are located behind the timing belt, requiring belt removal to access. Not the most technician friendly design. It is also strongly recommended to replace the tensioner roller, serpentine belt and inspect the tensioner seals for oil leakage.
