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 [...]

Volvo S60 Turbo – ETM and Crankcase Breather Problem

The Volvo Electronic Throttle Module (ETM) has earned a bad reputation, perhaps unfairly, for problems and early failures on the 1998-2001 cars. The ETM is the subject of a warranty extension by Volvo, now up to 10 years from the date the car was first put into service, or 200,000 miles. Volvo has also released a number of updates, both software and in service procedures to deal with these problems. This car in particular had a number of throttle fault codes stored in the engine computer. Volvo has released a Technical Service Bulletin (TSB) addressing this problem, with the recommendations [...]

BMW X5 – 4.4 Engine Coolant Loss

This BMW had a substantial coolant loss from the engine, in the area of what is termed the "valley pan". Service correction of this fault requires the removal of the intake manifold system, replacement of all seals and gaskets in the center engine area. While the manifold is removed, there are a number of vacuum lines and crankcase breather hoses which will need inspection and attention. BMW has released an update kit on some of the early engine crankcase breather systems, this is prime time to install this update. As you can see from the photos, it is also a [...]

Audi AllRoad and 2000 Volvo V40 – Rodent Damage

A mouse in the house, or in this case in the engine air box and under the intake manifold. A real problem in Maine, we've heard tales of using moth balls, dryer sheets, even pepper spray to repel the little critters. I'm not sure any of these really work, but I guess its better than traveling with some extra friends on board, worse yet, suffering wiring harness or engine damage from their "creations". Make certain your service facility checks for this when they are caring for your car, forewarned is indeed forearmed. Or to quote that tried but true old [...]

VW Diesel TDI – Clogged Intake Port

Low power, loss of acceleration on hills and under loads...all of these are symptoms of a clogged intake port on the VW 1.9 liter TDI engine. If you have 70K or more miles, and have not had a intake cleaning, chances are your intake port looks something like the one below. All the air for the engine must pass through this port, and as the port becomes clogged, airflow is reduced, the engine loses efficiency, and power output drops off. Imagine trying to breathe through a straw, and you have a good idea of how your engine feels. Since this [...]
