What affects the price on a BMW 3 Series
N47 diesel (318d, 320d, 325d, 2007 to about 2015)
The N47 has a well-documented timing chain fault. The chain sits at the rear of the engine, which makes replacement much more labour-intensive than a front-mounted chain or a cambelt.
Typical cost: Rear-mounted N47 timing chain: £1,800 to £3,500.
How we work out these prices
We start from the national range for this job at UK independent garages, taken from our how much does a cambelt replacement cost guide, and use the band for the BMW 3 Series's size class (premium car), because size, access and parts drive most of the difference between models. The BMW 3 Series-specific figures come from our BMW 3 Series common problems guide, which prices the faults known on this model. Your engine, gearbox, mileage and location all change the final bill, and labour rates in London and the South East are higher. These are guides, not quotes and not AutoFixFair prices: post your job to get real prices for your car.
