BMW X6 E71 buying guide
The first BMW X6, the coupé-styled SUV built from 2008 to 2014 on the same platform as the E70 X5, with revised engines from 2010. UK cars are mostly six-cylinder diesels, with six-cylinder and V8 petrols, all with xDrive four-wheel drive.
The versions
- Diesel on early cars: xDrive30d (M57, 235PS) and twin-turbo xDrive35d (286PS)
- Diesel from 2010: xDrive30d (N57, 245PS), xDrive40d (306PS) and, from 2012, the tri-turbo M50d (381PS)
- Petrol: xDrive35i 3.0 turbo straight-six (N54, later N55), 306PS, and xDrive50i 4.4 twin-turbo V8 (N63), 408PS
- xDrive four-wheel drive on every car, with Dynamic Performance Control spreading torque across the rear axle
- Automatic only: a six-speed on earlier cars and an eight-speed on later ones
- An ActiveHybrid X6 was sold in small numbers and isn't covered here; the X6 M has its own page
What to check on a E71 X6
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Shudder on tight turns
What to look for: In a car park, drive slowly at full lock in both directions. The car should turn smoothly with no judder, hopping or binding through the floor, and no drivetrain warning lamp.
Why it matters: Low-speed judder on tight turns is the usual sign of a worn xDrive transfer box. The X6 uses the same xDrive system as the E70 X5, where this is a known issue, more likely where the fluid has never been changed. Mismatched tyres add strain. A fluid change sometimes cures mild judder.
Automatic gearbox behaviour
What to look for: On the drive, from warm, feel for smooth changes up and down at light throttle, no flare in revs between gears, no shudder pulling away and no harsh engagement of Drive or Reverse.
Why it matters: The X6 uses the same gearboxes as the E70 X5, where the earlier six-speed automatic can develop torque converter, mechatronic unit and clutch pack problems, and benefits from BMW software updates. Smooth changes and updates on record are good signs.
Swirl flaps on early diesels
What to look for: On a pre-2010 xDrive30d or xDrive35d, ask whether the inlet manifold swirl flaps have been replaced or removed, and look for the invoice.
Why it matters: The early diesel shares its engine with the E70 X5, where the small flaps in the inlet manifold can break up and pieces can enter the engine. Specialists recommend replacing them every 60,000 miles or four years, or fitting aluminium replacements. Paperwork for this is a good sign.
