Symptoms of a failing turbo on a BMW Série 3 (E46)
On a diesel BMW Série 3 (E46), a turbo nearing the end of its life typically shows itself through a loss of power under acceleration, an unusual whistling noise as the revs rise, blue or black exhaust smoke, and an engine warning light on the dashboard. Excessive oil consumption or a metallic noise from the turbo outlet should also raise the alarm, as these signs often precede complete turbocharger failure.
About the new turbo for the BMW Série 3
This new turbo is compatible with reference 717478-5003S and is a direct replacement for the original turbocharger fitted to certain diesel BMW Série 3 (E46) models. It is designed to restore the vehicle's original performance — whether saloon, touring, compact, coupé or cabriolet — while meeting the boost pressure tolerances specified for this engine.
Engine compatibility and reference check
This new turbo is intended for diesel engines fitted with the M47 D20 (204D4) unit, with an engine capacity of 1995 cm³, as found on the 318d, 318td, 320d, 320td and 320Cd variants of the Série 3 (E46). Before placing an order, it is essential to check the reference number on your old turbo to confirm exact compatibility with your vehicle, as commercial designations can vary by market and production year.

Exchange basis and warranty
This new turbo is sold on an exchange basis: return of the old turbo is required in accordance with our Terms and Conditions, and it is only collected after the new turbo has been delivered and fitted, so your vehicle is never left off the road. It comes with a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over up to 10 instalments.
Fitting and maintenance advice
On the M47 D20 engine, the majority of turbo failures stem from insufficient lubrication caused by poor-quality oil, missed oil changes, or a clogged oil filter. A blocked air filter or a damaged intercooler can also accelerate premature wear of the turbocharger. Before fitting, check the oil circuit, the condition of the hoses, and the cleanliness of the air intake. After installation, prime the turbo with oil before the first start and avoid pushing a cold engine hard, in order to maximise the longevity of the part.
