Comprehensive E Series
Maintenance and Repairs
Owning a classic BMW is a joy, but these older vehicles do require knowledgeable care to remain reliable. Bay Diagnostic offers comprehensive maintenance for E Series BMWs, tailored to the needs of these models. We handle common wear-and-tear repairs that many E Series cars eventually need – for instance, cooling system overhauls (radiators, water pumps, hoses), suspension refreshes (bushings, shocks/struts), brake system service, and engine oil leak fixes (valve cover gaskets, oil pan gaskets). We’re also experts in BMW’s VANOS system and timing components, which many E Series models are known to require attention to as they age. In fact, our shop even has a dedicated BMW VANOS repair service given how frequently this comes up for older M52, M54, N52, and other BMW engines. No job is too big or too small – whether your E39 5 Series needs a Check Engine Light diagnosed or your E46 M3 needs a complete inspection and tuning, we have you covered.
In addition, we stay up-to-date on BMW factory maintenance schedules for older models. Following the recommended service intervals is key to prolonging the life of any BMW, and we can perform all scheduled services (Inspection I, Inspection II, annual services, etc.) to BMW factory specifications. By using correct fluids, filters, and reset procedures, we ensure your E Series continues to perform as the Ultimate Driving Machine it was designed to be. And if your model is a bit newer (early 2010s) with more advanced onboard diagnostics, rest assured our team knows how to reset service lights, register new batteries, update software, and more – just like the dealer, but with a more personal touch and at a better price.
