The Problem This 2010 Volvo XC70 came to us with about 96K miles, and a loud noise coming from the rear of the vehicle. The noise was noticeable at low and moderate speeds while driving, and sounded like a loud whine or hum depending on vehicle speed. Initially this noise sounded like a defective wheel bearing but on further exam we determined the noise was in fact coming from the rear differential, the gear system that transmits force from the transmission to the rear wheels. We've seen this before, both on the later model Volvo and the Land Rover LR2 vehicles, and [...]
Problem In our workshop, we see a number of transmission issues, on a number of different cars, from BMW, Audi, Volvo, and Honda. Almost always on vehicles not serviced by us, but rather referred to workshop by the dealer, or another repair facility. Over the years we've compiled a very effective set of diagnostic principles to make the determination of the failure mode, and corrective action, very straightforward. Prevention The old bromide that "An ounce of prevention is worth a pound of cure" never rang truer than in the case of the automatic transmission. Proper servicing, which is all too [...]
To Start For sometime now I’ve been involved with other shops, either in a consulting, or in an industry 20 Group. Over the years I’ve developed a set of criteria that I’ve shared with friends and family about how to properly evaluate where to obtain high quality, ethical auto service. These apply if your auto is an Audi, BMW, Mercedes, Lexus, Saab, Volvo or VW. Some of these items may seem basic, even commonsense, but all too often folks make the decision of where to take the car under duress, you want to have an ongoing relationship with shop before [...]
The Car The classic Mercedes 129 chassis (aside from being Bruce’s favorite car ever) also know as the SL300 and SL500, has to be one of the most amazing cars from a electromechanical technology standpoint. First released in 1989 and were in current production through 2002. The R129 replaced the R107 SL-Class in 1989 and was in its turn replaced by the R230 in 2003 (US). The R129 was produced as a two-door roadster with an automated (electro-hydraulic) textile tonneau cover. All R129s came standard with an detachable hardtop that could fitted by folding the canvas roof down and manually attaching it. [...]

Low Washer Fluid Warning The Problem Have you experienced a washer low level light that seems to stay on all the time, or worse yet, doesn't come on at all, even when the fluid is low or empty? This is something we are seeing more and more often, now that the New England snows have finally left us, problems with the fluid level sensors in customer car's washer solvent bottles. The problem seems to occur across the car lines we service, and doesn't seem to matter what kind of car, we've seen it in Audi, BMW, Mercedes, and Volkswagen. [...]
Drive Oil Level Data I title this when "Good Oil Pans Go Bad" to illustrate a point, 99% of the time, the engine oil pan does nothing but hold your engine's oil, but when the gasket between the engine block and pan fails, it's a bad thing. What Aside from the engine oil leak making a mess in your garage or parking space, and possible engine damage from low oil level, that oil has a nasty habit of finding it's way to your engine's catalytic convertor. Oil on a very hot item like a convertor at speed, aside [...]
