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 [...]

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 [...]

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 [...]

Volvo and Land Rover Differential Problems – Out Of Town – We’ll Repair – Send To Us

The Problem This 2010 Volvo XC70 came to us with about 96K miles, and a loud noise coming from the rear of the vehicle. The noise was noticeable at low and moderate speeds while driving, and sounded like a loud whine or hum depending on vehicle speed. Initially this noise sounded like a defective wheel bearing but on further exam we determined the noise was in fact coming from the rear differential, the gear system that transmits force from the transmission to the rear wheels. We've seen this before, both on the later model Volvo and the Land Rover LR2 vehicles, and [...]

BMW, Audi and Volvo Torque Converter Problems

Problem In our workshop, we see a number of transmission issues, on a number of different cars, from BMW, Audi, Volvo, and Honda. 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 determination of the failure mode, and corrective action, very straightforward. Prevention The old bromide that "An ounce of prevention is worth a pound of cure" never rang truer than in the case of the automatic transmission. Proper servicing, which is all too [...]
