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.

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.   [...]

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 [...]
