The BMW X1 (E84) is the Bavarian brand's first premium compact SUV. Based on the 3 Series Touring (E91) platform, it offers exceptional road handling, closer to a raised wagon than a true SUV. It received a facelift (LCI) in July 2012, bringing interior finish improvements and generalizing the 4-cylinder turbo engines (N20) to replace the naturally aspirated units. Although dynamic and offering excellent inline 6-cylinders in its early years, this model is marred by major reliability issues with its timing chains (N47 diesel and N20 petrol engines).
The BMW X1 E84 is a double-edged sword. If you're looking for driving pleasure, it's the best in its class thanks to its rear-wheel drive/xDrive architecture derived from the 3 Series. However, buying a 4-cylinder petrol (20i, 28i) or diesel (N47) version without a recent invoice for timing chain replacement is an extremely risky gamble. The expert's choice: Actively look for an xDrive25i or xDrive28i (pre-2011) model equipped with the naturally aspirated 6-cylinder (N52). This is by far the most reliable and refined engine in the range. If you opt for a 20i (N20), demand a 2015 model or budget €1500 to €2000 to make the timing chain reliable upon purchase. Avoid xDrive models where the 4 tires are not of the same brand and wear.
