Price of a BMW 1 Series Turbo
For the 1 Series, our turbos are priced from around £150 to £1,200.
Older 118d and 120d owners often pick a reconditioned turbo. The price is lower than new, while the rebuild meets the same quality bar as every other unit we sell.

How to Order
Small Car, Precise Parts
A 1 Series turbo is compact, and small differences between part numbers matter. The 123d was one of the first four-cylinder diesels with a two-stage turbo, and its parts differ from those in the 120d. We match each order to the code on your original unit.

BMW 1 Series Turbo Questions Answered
Oil supply problems are the most common cause. Many 1 Series cars do short town trips where the oil never fully warms up, so regular servicing goes a long way.
Yes. One small turbo works at lower engine speeds and a second, larger one joins in as revs rise. That extra hardware is why the part costs more than a 120d unit.
The M140i uses the B58 six-cylinder engine with a single twin-scroll turbo. We list two versions, so the part number on your car decides which you need.
