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. It's free, and when we need to top off a tire, one doesn't have to hunt around for tire dealer who [...]

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. The [...]

BMW Engine Camshaft Bolts Problem – Repair and Correction

What Happens 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 a check-engine warning light. Power to the [...]

Volvo Differential Rebuilding Service – Out of Our Area? Send Your Unit To Us

The Problem 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.

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 [...]

Vintage Mercedes Project – Or Reviving A Cold War Warrior

Vintage Mercedes Project - Cold War Warrior Mercedes 300TE The vintage Mercedes project car is on the road tonight, Jared, one of our Service Advisors is doing the overnight road test. Just one year before the Berlin war fell, this Mercedes rolled new out of the factory. I'm a Cold War fan, student and history buff, having grown up in that era, so this project had a special meaning to me, one of the last Mercedes to roll out when "West Germany" was still a country. Everything is done except for the engine oil leak reseal, will be [...]
