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.”
What is the problem?
The early version of the TFSI gasoline engines found in the A5, A4 and Q5 have an inherent design fault which leads to high consumption of oil.
The base problem seems to relate to the piston rings, which allow small amounts of oil to leak round the pistons into the cylinders, where it burns and therefore leads to high oil consumption. The typical way drivers become aware of this is when the ‘add one litre of oil’ notice comes up on the dashboard. When this comes up you don’t need to […]
We often get asked what are the “best” tires out there. Now “Best” and “Cheap” don’t really belong in the same sentence, so let’s pick another term “Best Value“. Value in terms of cost, durability and ride handling, for the next 3-5 years you own your car.
Without a doubt, and what we’ve based our business on, the “Best Value” in tires is Michelin. Hands down. It’s what I run […]
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 […]
