General X5 Forum (F15) / Remap M50D
« on: June 12, 2018, 02:34:04 PM »
I have booked my M50D in for a remap on Friday. Most of these only make 340-350 bhp but do reach the stated 740 nm torque. Projected results are 420-430 bhp and 850 nm.

I remember a recent thread where a remap ended with numerous problems but this thread seems to have been deleted. Anyone had a successful remap (not tuning box) and is there a noticeable difference? Basically miss my F10 M5 so this is to close the gap a little bit...

General X5 Forum (F15) / ZF gearbox service
« on: June 11, 2018, 02:26:48 PM »
My X5 may be in the higher mileage category, at 96.000 km,  so may be the first to ask this but I was considering having an oil service done to the gearbox. As I am in Belgium, I could go to one of the ZF centres, in my case in Dortmund, Germany.

I was quoted 675 euro, which seems a bit steep but having done some research it is very thorough service that takes a full 4 hours. ZF recommends having the service done every 100.000 km, as opposed to the "sealed for life" BS that BMW claims.

If your X5 was a keeper, would you have it done?

General X5 Forum (F15) / Fuel consumption M50D
« on: April 17, 2018, 01:03:50 PM »
I like my M50D more and more, and find it a very complete car that does everything well and just a "feel good" kind of car.

However, one surprise is the fuel consumption, which at 12 litres/100 km (= 23.5 mpg) over the last 2000 km is quite poor, and so far off the claimed 41 mpg that it is not even funny.

It has been a mixture of 70 % fast(ish) motorway duties (cruising 150 - 160 kph) and city driving. It equates to a range of about 700 km.

It is not far off what my F10 M5 was doing on the same kind of driving, which is a bit of joke considering that's performance.

Airfilter changed 5000 km ago, on 20" runflat tyres. I accept that a heavy SUV with 381 bhp will never be that economical but still was expecting 26-29 mpg on a run.

Anyone experiencing the same, or do I have a problem?

General X5 Forum (F15) / M50D: replace RFT with non RFT?
« on: March 25, 2018, 04:24:06 PM »
Generally I find the ride quality quite good in Comfort but having recently had the opportunity to lift the winter wheels, also in 20”, it struck me that they weigh an absolute ton and that the selection in RFT is also quite limiting when it comes to newer tyres. E.g the Dunlop Sport Max or Michelin 4S that I would prefer to the current Bridgestone.

Anyone did the swap and any improvement in ride (and possibly mpg)?

General X5 Forum (F15) / Leaking window washer
« on: March 19, 2018, 09:23:20 AM »
I have been greeted by a puddle on the left front wheel (looking at the car from the front), while the washer reservoir is on the opposite side.

No obvious leaking, and access is pretty poor, so before tearing into this or asking the dealer to look into it, has anybody had this problem?

I guess it could be a line from the left headlight washer that is leaking, as that would explain why it is on that side.

General X5 Forum (F15) / Ferric grey mirrors
« on: March 09, 2018, 07:50:41 AM »
My (new to me) X5 M50D in space grey does not have the ferric grey mirror covers. The first owner also went for full debadging, but was the mirrors in the body colour an option on the X5 M50D? As it is space grey, I don't really mind it, as the two shades of grey  ::) may clash somewhat. But anyone else had a delete of the ferric grey mirror covers?

General X5 Forum (F15) / 19” spare tyre kit
« on: March 05, 2018, 08:24:22 PM »
Tried looking for a spare tyre kit (space saver and jack) for the F15 but only find them in 18”. The 50D needs 19” to clear the front disc, but does a 19” kit exist? Of course a run flat tyre should be able to get you to safety, just prefer to have that extra safety as drive long distances, and not that practical to get the massive 20” tyre sizes in all parts of Europe.

Something like these: http://www.alloywheelsdirect.net/option/bmw_spare_wheel_kits
