“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 [...]

Electrical Issues – Telling Simple From Not

This vehicle was sent to us by another repair shop with the concern that it did not start, or would only start intermittently. The battery, starter, and finally the key switch were replaced in an attempt to get it to start. In fact, the starter was replaced twice. Then it was towed to our workshop. Mystery? Had the battle is recreating the problem, which it did here. Mystery? Not really for the Atlantic Motorcar Service Team, we see these cars day in and day out, we specialize in knowing, not just guessing. And when you do the same thing again [...]

Sometimes, It’s More Than Just Cars

Joe and our new Friend I Met A Hero Today My client with the vintage 1988 Mercedes project car we’ve been working on for the last month. A humble man, he’s currently 95 years old, joined the British RAF (Royal Air Force) at age 16, flew a Lancaster bomber against the Nazis at age 17 in the Second World War. Then after the war flew in support of the Berlin airlift, flying in supplies to the starving residents of West Berlin. He shared that he met Winston Churchill twice (Churchill remembered him on the second meeting), and recalled that [...]

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 [...]

Problem occurs with both "S" and non "S" models Carbon Deposits On Intake Valves As the largest Mini Cooper service specialists in Maine, at the Atlantic Motorcar Center we've noted a significant increase in late model Mini Coopers with cold start or cold running problems, even to the point of stalling, or Check Engine warning lights coming on.

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.
