Nitrogen And Automotive Tires – Peanut Butter & Jelly Or Snake Oil?

The Claim 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." All 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.

Mercedes Benz Intake Manifold Problems – And The Fix To Prevent It!

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). 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 so popular with many modern cars. Design The intake [...]

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 [...]
