BMW Water Pump Failure – How, Why, and What To Prevent

What This BMW 540 has was diagnosed with a defective engine coolant pump. Symptoms were overheating and damaged drive belt system.

Rear Fog Lights – Truth and Fiction

Rear Fog Light Switch - Volvo Intent and Design For the new owner of a European auto, the rear fog light is often a source of great mystery, chances are they've never seen it before on their domestic car or truck. A common question we are asked is "Why does my European car have only one fog light". Or an equally common question, "I think I have a rear fog light out, only the driver's side seems to work."

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 [...]

AMC Service Tip – Replacing Stuck or Blind Hole Bearing Races

Problem Removing Stuck Bearing Races Tapered roller bearings are commonly found in wheel bearings, transmission, differentials, and other automotive systems. They consist of two parts, the bearing cone with the roller bearing, and a “race”, which is the highly polished and hardened surface on which the bearing rides. The race is pressed into the part or casting and the roller bearing installed on top of it. So let’s say you have a bearing race (transmission, wheel, differential or other) in a “blind” hole that you need to replace. By “blind” we mean you can’t access it from the back of the [...]
