A new turbo designed for everyday use on the BMW Série 3 (E46)
The BMW Série 3 (E46) 320d, 320Cd and 320td is frequently used for long road and motorway journeys interspersed with urban driving. This repeated demand on the turbocharger, combined with frequent high-rev use, exposes the M47 D20 (204D4) diesel engine to progressive turbine wear if the oil circuit is not maintained rigorously. A new turbo restores reliable performance on this engine, which is particularly sensitive to lubrication quality.
Compatibility with Série 3 (E46) engines
This new turbo is compatible with reference 731877-5010S and fits the BMW Série 3 (E46) in the 320d, 320Cd and 320td variants, all powered by the M47 D20 (204D4) diesel engine with a capacity of 1995 cm³. Before placing an order, we recommend checking the reference on your old turbo or on the engine plate to confirm exact compatibility with your vehicle.

Exchange and warranty for your 320d, 320Cd or 320td
This new turbo is sold on an exchange basis: in accordance with our Terms and Conditions, return of the old turbo is required, but it is only collected after the new turbo has been delivered and fitted, so your BMW Série 3 is never left off the road. The part carries a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over up to 10 instalments.
Common symptoms and causes of failure on the M47 D20
On this diesel engine, a loss of power, abnormal exhaust smoke, excessive oil consumption or an unusual whistling noise should all raise concerns about the condition of the turbo. The most common causes of failure are inadequate lubrication, poor-quality oil or missed oil changes, a clogged air filter or a damaged intercooler, as well as driving habits involving sudden high-rev bursts without a warm-up period.
Fitting advice to protect your new turbo
Before fitting this new turbo to your 320d, 320Cd or 320td, carefully inspect the oil circuit, the condition of the feed and return hoses, and the cleanliness of the air intake and intercooler. When starting up for the first time, it is essential to pre-lubricate the turbo with oil before the initial engine start, to ensure immediate bearing lubrication and extend the service life of the part.
