Repair and maintenance information for BMW vehicles
TOP 3 BMW REPAIR PROBLEMS
Bavarian Motor Works or BMW is a renowned manufacturer of luxury vehicles. The manufacturer began engineering automobiles in the 1920s, and its current generation of automobiles still carries the same elegance and sophistication as it did then. However, there are problems with general build quality and durability, particularly the BMW E36 1992 to 1999 models. Critics attribute this to this to subpar-quality materials used for the body panels. Dashboards and door panels are usually the first body components to give in. Overexposure to UV rays usually cause dashboard cracks and damage. On the other hand, BMW door panels are prone to rust build-ups. The first thing to do here is to inspect the damaged panels. Measure the extent of damage and determine if the part really needs to be replaced. If there are only minor damages, then only minor repair work is necessary. Take this as an example: inspecting door panels. Perform an ocular inspection to spot rusty areas on the panels. If the amount of rust is small and limited to the edges, just use anti-corrosive spray to remove them. Refer to our How to Replace Door Shell manual. You can replace or upgrade your dashboard with dash kits for better performance and durability. You can also read this dash kit replacement guide.
Unlike most of its predecessors, the BMW E46 generations had solid auto bodies. However, these models are known to have weak cooling systems. The water pumps and radiators need to be well-maintained to ensure excellent overall engine performance. The main indicator of an underperforming cooling system is constant overheating and excessive water consumption. Regular replacement of the water pumps every 60,000 miles and radiators at 100,000 miles prevents cooling system problems. Just remember to pick high-quality OEM replacements. Refer to our manuals on radiator replacement and water pump replacement for easy-to-follow instructions.
BMW E90 sedans and E92 coupes are prone to fuel system problems. The most prevalent problem in the two models is their high-pressure fuel pumps. Just like any engine, the BMW relies on fuel pumps for proper circulation. And once a pump is faulty, it can cause major engine underperformance. When one or both fuel pumps malfunction, fuel fails to reach the direct injection system, and the car will stall. It can also result in engine misfires and slow acceleration. A fuel pump will show warning symptoms when it needs to be replaced. When it starts overheating and becomes inoperative for around 20 minutes, this usually means that it needs to be replaced. But before you buy a replacement fuel pump, double check the relay and the wiring system because these two components can also cause sudden engine stalls. If the two components are in top shape, then have your fuel pump replaced. This is a task for an experienced do-it-yourself (DIY) mechanic, and beginners should not try to experiment, especially since this task deals with the fuel system. Here are easy-to-follow DIY tips for installing a new fuel pump (http://www.automd.com/62/how-to-replace-a-fuel-pump).
