What changes behind the wheel of your BMW Série 5 550i with a turbo in good condition
On a BMW Série 5 550i, the feeling of instant power on pull-away and a crisp response when accelerating out of corners depend directly on the condition of the turbo. As soon as a loss of boost pressure occurs, the driver notices a sluggish throttle response, an unusual whistling noise, or smoke from the exhaust. With a correctly fitted new turbo, the saloon regains its linear power delivery and driving refinement, free from hesitation or rev drop during gear changes.
Compatibility of the new turbo for the BMW Série 5 550i
This new turbo is compatible with reference 821613-5004S, intended for the 550i engine — a 4395 cm³ petrol unit carrying engine codes N63 B44 A and N63 B44 B. Before placing an order, it is recommended that you check the reference marked on the old turbo or on the vehicle's identification plate, as several variants of this engine block may have been fitted to the Série 5 depending on the version.
Exchange basis and warranty for this new turbo
This new turbo is sold on an exchange basis: return of the old turbo is required, in accordance with our Terms and Conditions, but it is only collected after the new turbo has been delivered and fitted, so that your BMW Série 5 is not left off the road. A 12-month parts warranty applies, subject to fitting being carried out by a qualified professional. Payment can be spread over several instalments, in up to 10 instalments.
Fitting advice for the 550i turbo
On the N63B44 engine, lubrication plays a crucial role in turbo longevity: using the correct grade of quality oil and adhering to the recommended service intervals will limit premature wear of the bearings. Before fitting, it is important to check the oil circuit, the feed and return hoses, and the cleanliness of the air intake and intercooler, as any contamination can damage the new turbo. On first start-up, priming with oil is recommended to ensure immediate lubrication of the components before the engine is first revved.
