| Tech Tip Dv Auto Solutions has been receiving a fair amount of calls on check engine light indications regarding O2 sensor malfunctions. Before anyone proceeds on spending money on O2 sensors and other possibilities, please take these tips into consideration. When BMW vehicles run lean, in most cases the ECU will throw a code that can give individuals the perception that their Bavarian Machine needs O2 sensors. When in reality this can be because of a lean mixture caused by a vacuum leak or a dirty intake manifold. On late models of BMW vehicles, this means v8 and i6, this is a typical problem. Vacuum leaks are created on a normal wear and tear conditions that cause the gaskets to separate, harden, and leak. Vacuum leaks can cause rough idle but not all the time. Remember, vacuum leaks come in all sizes. The bigger the leak the more noticeable it will be in the system will. Sometimes they are so little that the only way of detecting small vacuum leaks are by performing a smoke test. Also, keep in mind that these cars also have problems with carbon build up which clogs some of the passage ways where air flows into the intake manifold system. Time after time, when we perform intake manifold gaskets services because of vacuum leaks, we have to repair the hoses under the intake manifolds and unclog the airways. This will give a better acceleration and clean all restrictions from the intake system. If this service is not performed, this can create massive head damage. These symptoms, if understood, can be easily diagnosed. Coming to our shop for a free check up will not only save you money, but it will also keep your ultimate driving machine operating at its full potential.
