N54 to B58: we speak fluent Bavarian failure mode.

BMWs reward maintenance and punish deferral. Dev's bench runs ISTA with full coding support, and the parts shelf carries the gaskets we replace every single week. Bring us the twin-turbo six you were warned about — we like them.

The failures we actually see — and what we charge

Real prices move with parts and model year; these are honest starting points, not bait. Every job carries the 36-month / 36,000-mile warranty.

N54 fuel injectors

from $620 each

Symptom: Cold-start stumble, fuel smell, cylinder-specific misfires

Index-matched OEM injectors — only the failed ones, tested individually

Valve cover & gasket oil leaks

from $480

Symptom: Burning oil smell, oil on the exhaust manifold

OEM gasket set; cover replacement when the plastic has warped

Oil filter housing gasket

from $520

Symptom: Oil in the coolant's neighborhood — the classic N20/N52 leak

Gasket and coolant service in one visit

VANOS solenoids & timing faults

diag $175, credited

Symptom: Rough idle, limp mode, cam correlation codes

Diagnosis first — solenoids are $95 each, timing jobs are not

Hearing one of those symptoms? Diagnosis is $175 for the first hour with factory scan tools — credited to the repair when you approve it.
