Common BMW problems we fix

A few of the BMW issues we see most often — and how we handle them.

Oil leaks (valve cover, oil filter housing, oil pan gaskets)

As BMWs age, the valve cover gasket, oil filter housing gasket, and oil pan gasket become the usual leak points — you'll notice drips, a burning-oil smell, or residue under the car. We trace the leak to its source and reseal it with updated parts before a small seep turns into a big repair.

Timing chain wear on N20/N26 4-cylinders

The N20 and N26 four-cylinders are known for timing chain and guide wear; a rattle on cold start is the classic warning. We inspect the chain, guides, and tensioner and replace them as a set before a stretched chain does expensive damage.

Cooling system failures (water pumps, thermostats, expansion tanks)

BMW cooling systems use a lot of plastic that gets brittle with heat cycles — water pumps, thermostats, and expansion tanks are common failure points that can lead to overheating. We test the system, replace the weak links, and bleed it properly to protect the engine.

Models we service

All of them — from brand-new to decades old. Many shops turn away older vehicles; we don't. Whether your BMW is this year's model or a classic you've kept alive for twenty, it gets the same dealer-level diagnostics and care.
