BMW X5 35d Diesel Problems and Repair Costs
The X5 35d diesel repairs owners report are the EGR cooler (P2457 code, with a BMW recall on 2014 to 2017 cars), the diesel particulate filter and the NOx sensors, and a cheap spring or sensor fix sometimes clears the code before an expensive part is needed.
Last updated · By BimmerQuote (how we build guides) · Costs on this page come from the linked repair pages, each citing its sources.
What this covers
Our repair pages tie these jobs to the E70 X5 xDrive35d and E90 335d (M57), and the F15 X5 xDrive35d (N57). The engine pages are BMW M57 engine and BMW N57 engine. These are repairs owners reported, not failure rates.
EGR cooler
A P2457 EGR cooling performance code, limp mode (especially on cold starts) and coolant loss with no visible leak are the signs. Before paying for a cooler on a 2009 to 2013 car, have the bypass-flap spring checked; owners in the source thread fixed it for under ten dollars. For 2014 to 2017 X5 35d, EGR coolers fall under BMW recall 18V-755, so check eligibility by VIN first. See X5 35d EGR Cooler (Diesel).
A DPF or emissions warning, reduced power and frequent or failed regenerations point to the filter. Check the differential pressure sensor and try a forced regeneration before replacing the DPF. The independent figure in our data is for cleaning only, so it is not comparable with the dealer replacement quote. See Diesel Particulate Filter (DPF) – X5 35d.
NOx codes such as 4D16, an incorrect exhaust fluid warning or a DEF no-start countdown can mean a failed sensor. The two positions use different part numbers, one owner was sold the wrong one, and a bad SCR mixer or DEF valve can make good sensors read wrong, so diagnose before buying two. An SCR adaptation reset is needed after replacement. See NOx Sensors (X5 35d / Diesel).
Owners priced the EGR cooler, the DPF and the NOx sensors. That reflects what owners reported, not a measured failure rate.
