AMC Tech Q & A – Oil Change Intervals

Question A question we sometimes get is - "Curious about oil changes. Synthetic has been around 15000 miles. Looks like you recommend 5,000?" Answer To which we are glad to reply, "Great question!" Yes, we do recommend a shorter interval for older cars. We have an expression, "Oil is cheaper than metal," I'll explain. We all know that oil is used to lubricate the engine components to maximize wear and tear, it also serves transfers heat and helps filter out contaminants from engine operation. Here's Why First, let's address why we change the oil. It's for two reasons, one is [...]

Audi, BMW and Mini Cooper Carbon Build Up Correction (Decarbonization)

The Problem BMW and Mini Cooper (along with other vehicles) with Gasoline Direct Injection (GDI) engines are both cars that can experience carbon build up over time causing drivability and performance issues. GDI is a met hod that automakers have used to inject gasoline at a high pressure directly into an engine’s combustion chamber rather than into the intake tract or cylinder port.  Fuel is better measured than older fuel injection or carbureted systems - making the vehicle more fuel efficient, as well as yielding more power with an engine of identical displacement. The Audi, BMW engines and the Mini Cooper N12 and N14 (along with later [...]

Why Did This Happen to My Car? – Prevention vs. Repair

AMC Answer Series - Why Did This Happen to My Car? The Question It happens all too often. At least 2 to 3 times a week, vehicles are towed into Atlantic Motorcar for major repairs.

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 that the real reason for [...]

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.   [...]

AMC Tech Tip – Low Tire Pressure Warning Lights In Cold Weather

AMC Tech Tip – Low Tire Pressure Warning Lights In Cold Weather What As winter approaches, many motorists will experience a low-pressure warning light on the dash or simply observe that the tires look a bit less full than they should. The main reason for this is the dropping temperatures, which cause the air to become denser and consequently lower the tire pressure. Of course, tires naturally lose pressure over time, or there can be a puncture. Why Tire pressure monitoring systems (TPMS) are a real boon to safety and convenience, and they have been required on all new cars [...]

BMW and Mini Battery Registration (Replacement)

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 the registration process after replacing a [...]

BMW and Mini Cooper Turbo Failure

Problem 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 [...]
