H&B Karmakanix Auto Repair Services

The H&B Approach to Service Auto Repair

As automobile technologies evolve, so do their servicing needs. In some basic respects, cars have become more reliable, and — according to Consumer Reports — their useful life has at least doubled in the past thirty years. In the 1970’s, one hundred-thousand-mile cars were considered worn out. With current technology, the useful and cost-effective life of a well-maintained car is more than double that.

At the same time, thanks to ever-increasing electronic and computer components, cars have become much more complex. We in the service business are now in what is called the “era of non-pattern failures.” This means that these more complex cars fail less frequently, but in less predictable ways. For this reason, we need ever more sophisticated tools to troubleshoot the complex kinds of problems which appear. At H&B, we meet this challenge with the focus of 40 years of experience specializing in only two brands of cars, only recently adding a third. Consequently, we keep up with service bulletins, recalls, and other information unique to these cars.

Routine servicing remains no less important, and we emphasize the importance of monitoring the safety systems on these cars. We see increasingly the consequence of less frequent service intervals in worn out tires, thin brakes, leaking cooling systems, low oil levels. For that reason, we strongly recommend a yearly safety inspection, even if no dash warnings are on display.

We do not, however, “upsell” our customers. We are happy when repairs turn out to be inexpensive. Our interest lies in extending the useful, cost-effective life of your car, and often that means deferring repairs which aren’t urgent and can wait awhile.

For this reason, we develop a maintenance checklist for the future of each car. By keeping close track of what has been done and what lies ahead, we try to avoid unpleasant surprises and maximize your driving pleasure.

H&B works by appointment, though we do try to accommodate both emergencies and pre-purchase inspections. And with appointments, we have a generous free loaner-car policy: just let us know your transportation needs, and we will try to meet them. To book an appointment, please call (510) 549-1515 or email info@hbspecialists.com.

Condition-Based Service

2002 & Later BMW & Mini Cooper Models

Beginning with model year 2002, BMW began phasing in a new type of service schedule for all its models. The first to get this was the ’02 745i; then the ’04 5-series; then the 3-series, and so on. The idea behind “condition-based servicing” is that the car knows what it will need and will remind you. Its needs will vary according to the amount of time and miles driven, but also according to the kind of driving done: whether mainly on the highway, around town, or mixed.

In practice, this results in a variety of different messages on the dash display, from “brake linings” to “cabin air filter” to “brake fluid” to “vehicle check.” The challenge, then, is to piece all these items together in a coherent service plan so that your car’s reliability is maintained with a minimum of surprises. For this purpose, H&B has updated its service menus to integrate the newer “condition-based servicing” approach into regular servicing schedules. This incorporates newer, computer-based diagnostic routines along with the normal safety inspection and servicing.

For most BMW models before 2002* and Minis before 2007, sample service menus are shown below. Minor services and oil changes should fall at intervals between these major services.

* BMW 5-series 2004, 3-series 2006
