Is 525d M57?
BMW 5 Series E60 525d 3. Diesel M57 Auto Bare Engine 194BHP 91k M57N2/306D3. The B57D30B is widely considered the most reliable BMW diesel engine today. It’s a 3. L inline-six with modern technology, a long-lasting timing chain design, and low failure rates. It’s built for high mileage and smooth power delivery, making it perfect for daily use, long trips, and even towing.BMW timing chains have snapped on a range of models across the 1, 3 & 5 Series, most commonly affecting the N47 diesel. We also rebuild M57 & N57 diesel engines, BMW petrol engines & also BMW Minis. From 2015 to the present, the B47 diesel engine also suffers with an inherent ‘bottom-end’ failure.BMW timing chains have snapped on a range of models across the 1, 3 & 5 Series, most commonly affecting the N47 diesel.

What are common problems with the 525d?
BMW 5 Series years to avoid 2010-2014 520d/525d diesels (early F10/F11) – Early Mk6 diesels again use versions of the N47 engine, so timing chain issues remain a concern on high-milers, particularly where oil changes have been stretched or service history is incomplete. The timing chain of the BMW E60 shows considerable weaknesses in various engine variants, which become noticeable through characteristic symptoms. The 525i 218 hp, 530i 272 hp and 525d 197 hp engines are particularly affected, with the first signs of a stretched timing chain appearing as early as 80,000-120,000 km.A top speed of 158mph made the European M635CSi the second fastest BMW ever built, next to the M1. The new BMW M6 Concept made its debut at the 2005 Geneva Motor Show. It shared the same 5. V10 engine and SMG III gearbox as the E60 M5 and produced 500bhp. BMW claimed it accelerated from 0-62 mph in 4.
What is the difference between 525d and 530d?
The 525d has weaker pistons material wise and they’re not as heat resistant afaik. If LCI then the difference is injectors which are solenoid 209 compared to piezo on 30d, gearbox 6HP21 compared to 6HP26/28 and cylinder head that has smaller intake ports. Early 525d were a de-tuned 3. Later 525d are a twin-turbo 2. So those will be very different in terms of smoothness, the 3.
