High Torque Starter Motor - BMW 3.0L L6 2008-2011 (OE 17922 / LRS02298)

A High Torque Starter Motor for BMW 3.0L L6 Applications

This is a high torque starter motor built for BMW 3.0L inline-six applications from 2008 to 2011, OE number 17922. If your BMW has started cranking slowly, clicking without turning over, or not engaging at all, a worn starter is one of the most common culprits, and this is a direct replacement built to OE specifications rather than a generic aftermarket guess.

What a Starter Motor Does

The starter is the small but powerful electric motor that spins your engine over just long enough for it to catch and run under its own power. It's built to deliver a short, intense burst of torque rather than run continuously, which is why starters are wound and geared differently than most other motors on the car. Over years of use, the internal brushes wear down, the solenoid contacts pit and corrode, and the whole unit gradually loses the crisp, immediate engagement it had when new — which is usually the first sign something's wrong.

OE Cross-Reference Numbers

This starter is built to OE number 17922 and cross-references to the following part numbers, which is worth checking against your old unit before ordering: Denso 428000-1760 and DSN1375; BMW 12412344243 and 12412354701; Wai/Transpo 17922N; Lucas LRS02298 and LRS2298; J&N 410-24145 and 410-52457; and Bosch 0-001-107-423 and 0-001-107-424. If your old starter carries any of these numbers, this is a confirmed match.

Fitment

This starter is listed as compatible with BMW 3.0L L6 applications from 2008 to 2011, with the BMW 1 Series M 3.0L (2011) specifically confirmed as a match. BMW used the 3.0L inline-six across several models and body styles during this period, so if you're not driving a 1 Series M, it's worth cross-referencing the OE numbers above against your vehicle's original starter before ordering rather than assuming fitment based on engine size alone. Our Request a Part page is the fastest way to confirm if you're not sure.

Signs You Need One

A failing starter usually announces itself gradually before it fails completely — a slow, labored crank that used to be quick and sharp, an intermittent clicking sound when you turn the key without the engine turning over, or occasional no-start situations that seem to resolve themselves if you try again a few minutes later. Wikipedia's starter motor article covers the electromagnetic principles behind how these motors generate that short burst of high torque, if you want the deeper technical explanation.

Installation Notes

Starter replacement varies quite a bit in difficulty depending on where BMW mounted it on your specific engine — on some inline-six applications it's reasonably accessible from underneath, while on others it's tucked in behind the intake manifold and takes considerably more effort to reach. It's worth looking up a repair guide specific to your exact chassis code before starting, since the mounting bolts and electrical connections are usually straightforward once you can actually get a wrench on them.

Why Get This Right the First Time

A starter that's replaced with the wrong torque rating or amperage draw can either fail to turn the engine over reliably in cold weather or put unnecessary strain on your battery and charging system. Matching the OE specifications listed here — rather than guessing based on a generic "fits most BMWs" listing — is the difference between a starter that works the way the factory unit did and one that leaves you stranded on a cold morning.
