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.”
Many owners of late model Mercedes-Benz cars equipped with 3.0 and 3.5l V6 engines (M272 or M273) have been experiencing similar problems in performance lately, which include poor idle, loss of power, and a check engine light with the code P2006 (and sometimes others).
The problem is caused by an air flap inside this Mercedes-Benz intake manifold breaking, causing unexpected low acceleration depending on the orientation of the flap that has broken. To thoroughly understand what is going on here, let’s review what the system is doing and why variable-intake-runner intake manifolds are becoming […]
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 […]
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 […]
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 […]
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 […]

I Met A Hero Today
My client with the vintage 1988 Mercedes project car we’ve been working on for the last month.
A humble man, he’s currently 95 years old, joined the British RAF (Royal Air Force) at age 16, flew a Lancaster bomber against the Nazis at age 17 in the Second World War. Then after the war flew in support of the Berlin airlift, flying in supplies to the starving residents of West Berlin.
He shared that he met […]
