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.”

You’ve likely see 0r heard the claim, “Nitrogen gives me better fuel economy, makes my tires last longer, and I don’t lose air from my tires. It’s more responsible for the environment.”

Nitrogen in TiresAll noble and good things, except…actually, we’re all riding on nitrogen filled tires. Let’s let that sink in for a moment and I’ll explain. So called “normal” air, that stuff is all around you and me, but we can’t see, is composed of 78% nitrogen. It’s free, and when we […]

By | January 22nd, 2018|Categories: Case Studies|Tags: , , , , , , , , |Comments Off on Mercedes Benz Intake Manifold Problems – And The Fix To Prevent It!

Mercedes Intake Manifold Happens
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).

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 in short order.

The #1 reason for battery […]
