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.

Excellent service. Rebuilt my k04 turbo with an uprated thrust bearing which is capable of 350bhp as the original one had shot to bits. Thanks again.

Essex Turbos refurbished the turbo for my 2.0 TDI CBB engine for £450-500. They were consistently very friendly over the phone and in person. One of the engineers visually inspected a turbo I had bought and had an issue with free of charge - a deconstruction and a written report is £150, but would not have helped me in this situation. I have had no problems with the refurbished turbo, but if I did, they have a good complaints process to which they would inspect how it broke and decide whether it was their fault or not. I very much trust their honesty if it came to this. They dealt extremely well with a phone call they received from the other turbo company I dealt with threatening to sue them. I would definitely come back if I get future turbo-related problems.

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.
