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.”

Tech Tip – The Truth About Lifetime Transmission Fluids – “Oil is Cheaper Than Metal”

By | January 15th, 2018|Categories: Case Studies|Tags: , , , , , , , , , , , |Comments Off on Tech Tip – The Truth About Lifetime Transmission Fluids – “Oil is Cheaper Than Metal”

BMW, Mini Cooper Transmission Fluid

There is a trend with many manufacturers to use so called “Lifetime” transmission fluids in their new cars. Audi, BMW and Mercedes have been doing this for years.

The real question is what is a “lifetime”? If the lifetime of the car is the reference point, most owners will be sorely disappointed, for it seems to us that almost all of the fluids need service around 60K miles, far shorter than the lifetime of most European cars. While fluids and lubricants have doubtlessly improved over time, we suspect […]

BMW and Mini Cooper Battery Replacement – Registering New Battery

By | January 15th, 2018|Categories: Case Studies|Tags: , , , , , , |Comments Off on BMW and Mini Cooper Battery Replacement – Registering New Battery

Did you know that the BMW engine computer, known as a DME (Digital Motor Electronics) must be programed to know a new battery has been installed?

Our Senior Service Technician Nick explains why. We’re obviously playing up the humor here, but the topic isn’t a joke, it’s a real issue.

Otherwise the battery can under or overcharge, and cause premature battery failure. Older batteries become sulfated with time and require a higher charging rate. So unless the DME is notified a new battery is installed, it will often overcharge, and damage the new battery […]

What Happens
Certain late model BMWs can experience a problem with the camshaft sprocket retention bolts failing.
This is a design defect, and well know in professional BMW service circles.
You can see on the photo below, that VANOS (variable valve timing system) to intake camshaft bolts have broken and backed out, 3 of the 4 bolts are damaged and loose.

BMW said “in very rare cases the bolts holding the variable camshaft timing (Vanos) unit housing may become loose or, in extreme cases, break.” In such cases, the driver would be alerted by […]

Volvo Differential Rebuilding Service – Out of Our Area? Send Your Unit To Us

By | January 4th, 2018|Categories: Case Studies|Tags: , , , , , , , , , , , , , |Comments Off on Volvo Differential Rebuilding Service – Out of Our Area? Send Your Unit To Us

The Problem
The rear differential design has been in use in the Volvo world since the 2008 to at least the 2014 model year, so it’s something to consider if you own a vehicle in that range. We service a tremendous amount of Volvo XC70s, and have seen the problem largely on those models, but have read reports of it being an issue on the S80 as well. Now the earlier Volvos had their own set of differential or bevel gear problems, which you can read about on our blog at Volvo AOC […]

On Road Test

Vintage Mercedes Project – Cold War Warrior

The vintage Mercedes project car is on the road tonight, Jared, one of our Service Advisors is doing the overnight road test.

Just one year before the Berlin war fell, this Mercedes rolled new out of the factory. I’m a Cold War fan, student and history buff, having grown up in that era, so this project had a special meaning to me, one of the last Mercedes to roll out when “West Germany” was still a country.

Everything is done except for the engine oil […]
