BMW, Audi and Volvo Torque Converter Problems

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.

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 [...]

The Measure Of A Workshop – Or How To Find A New Home For Your Car

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 [...]
