Car Owners Hub UK - Built by Drivers, for Drivers

Have a pleasant evening.
The 2011 BMW X5 30d was a recent purchase of mine. The car didn't have a service record, but I acquired it after a short inspection and negotiated a fair price. I immediately began servicing it, replacing the batteries, top mounts, and gearbox and sump. I also replaced the front springs.
The vehicle is now easy to drive. Maintains a strong pull and responsiveness level. My sole apprehension is the peculiar sensation of regen braking that I experience when slowing down. Almost as if the brakes are pressing down harder than I'd like them to. At low speeds, when shifting down a gear, the engine will sound like it's rev matching, which adds to the strange sensation of braking or slowing down.

This is my first X5, so I don't know what to expect from the driving characteristics or whether this is typical. Though the revving that occurs during downshifting is constant regardless of temperature, it seems to be much worse when the car is hot and is only really noticeable when cold.
Would much appreciate any guidance or assistance.
My sincere appreciation.

An auto-rev matching technique, commonly referred to as a "throttle blip," causes BMWs (both manual and automatic) to rev slightly when downshifting. A more seamless transition, less drivetrain jerkiness, less clutch wear, and faster acceleration are all results of this operation, which momentarily increases the engine RPM to match the lower gear's speed.


By blipping the throttle during downshifts, modern BMWs, particularly those in Sport or Sport+ modes, automatically rev-match the engine speed with the wheel speed. A professional "heel-toe" downshift is imitated here.
Purpose: The primary reason is to prevent the car from jerking when the clutch re-engages in a lower gear. In its absence, the engine's revolutions per minute (RPM) would go too low, which would shock the driver and put strain on the clutch and gearbox.
The logic of the automatic or DCT gearbox already has it programmed in. It is possible to disable this feature in some manual cars by disabling Dynamic Stability Control (DSC), but it is typically activated by default in these vehicles.
Smoother and more regulated engine braking may also be provided by the engine Control Module (DME) using this technology.

Personally, I'd make sure the brake calliper isn't binding as well.

Thank you for getting back to me. Thus, rev matching is typical. Well done, I appreciate it.
Are you of the opinion that a calliper's regenerative properties make its braking more severe when cold and less severe when heated? When travelling at low speeds, the vehicles experience what seems like a bogging down. Once again, I am grateful.

You should also examine the brakes for binding and the tires for damage; the transfer box can't take a hit if the tread depths vary on the same axle or between them.

It seems like 4mm all around. If I'm being really honest, I intend to change them next. They have terrible riding quality and run flats.
