Case Studies – Our Service Solutions
A Collection of the Odd, Unusual and Interesting Found While Servicing our Client Vehicles.
Originally intended as a showcase for customers of our workshop and staff’s abilities, this page has evolved in an interesting and informative teaching tool, and one of the most popular pages on our site!
By nature, these are rather extreme examples of failures, and not what we typically find during service. Our goal at Atlantic Motorcar is to prevent these from happening to you and your car. But rest assured, if we can fix these challenges, regular maintenance is breeze!
We like to call this our “YES WE CAN!” page. You can also view many of these concerns on our Facebook page. Each photo can be enlarged by clicking on it.”
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 it’s […]
The electrical system in late-model Minis and BMWs is quite sophisticated, in that it tailors charging as closely as possible to both the type and age of the battery. The Engine Management computer also controls the alternator output. When replacing a battery, this computer needs to be informed if you’ve replaced the battery or updated the vehicle from a conventional Lead Acid battery to an Absorbent Glass Mat (AGM) type; it charges the AGM differently than a traditional battery.
How It’s Done
This process of updating the alternator-control computer is called Battery Registration. Ignoring […]
Tech Tip – Volvo Fuel Filter Changes, Prevent Problems and Save Money
See the photo?
That’s a electric fuel pump, you don’t want to have to buy one, read on for a a quick way to save yourself some real money, and headache!
Volvo has a 105K or 120K mile schedule for replacement of the engine fuel filter. Lately we’ve been seeing an increasing number of the Volvo electric fuel pumps failing.
Prevent Rather Than Repair
We feel that this problem is brought about by extended intervals between fuel filter replacement. In the past, fuel filters were […]
A common yet avoidable problem we see with BMW and Mini Coopers is turbocharger failure. Turbocharger failures can be catastrophic, so they are important to address at the first sign of a problem. As its name implies, a turbocharger is a device increases the power output of an engine.
In our workshop, we see a number of turbocharger or “turbo” issues, on a number of different cars. 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 […]
What It Is
A vehicle’s passenger occupancy sensor detects whether a passenger is in the seat and decides whether or not to allow the airbag to deploy in the event of an accident. If the sensor determines a weight on the seat is not a person, the airbag does not deploy. The traditional seat occupancy sensor is a mat sewn under the upholstery on the surface of the seat. Beginning in 2006, manufacturers began replacing traditional seat occupancy sensors with occupancy classification sensors that not only determine whether the weight in the passenger seat is a person or not, but also attempt […]
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.
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 […]
