What changes behind the wheel of your BMW 5 Series 550i with a healthy turbo
On a BMW 5 Series 550i, the feeling of instant power on pull-away and the sharp response when accelerating out of a corner depend directly on the condition of the turbo. As soon as boost pressure drops, the driver notices a sluggish throttle response, an unusual whistling noise, or exhaust smoke. With a correctly fitted new turbo, the saloon regains its smooth, linear power delivery and driving pleasure, with no hesitation or rev drop during gear changes.
Compatibility of the new turbo for the BMW 5 Series 550i
This new turbo is compatible with reference 821613-5004S, designed for the 550i powertrain fitted with the 4395 cm³ petrol engine carrying engine codes N63 B44 A and N63 B44 B. Before placing an order, it is recommended that you check the reference printed on the old turbo or on the vehicle's identification plate, as several variants of this engine block may have been fitted to the 5 Series depending on the version.
Warranty and delivery of the new turbo for the 550i
This new turbo is sold as a straightforward purchase: there is no old unit to return, and delivery is made in a single shipment. A 12-month parts warranty applies, subject to fitting being carried out by a professional. Payment can be spread over multiple instalments, in up to 10 instalments.
Fitting advice for the 550i turbo
On the N63B44 engine, lubrication plays a vital role in turbo longevity: using the correct grade of quality oil and adhering to the recommended service intervals will limit premature bearing wear. Before fitting, 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 the oil system is recommended to ensure immediate lubrication of the components before the engine is first revved.
