Highest Mileage!!
 

I am very curious. What is the highest mileage anyone has done on a 3.0 engine? I have read and heard that the 6L is a very robust and stout engine. I want to know how high the mileage is on the oldest X5's? :popcorn:

My friends 2007 E70 3.0d has done 950,000km... still going strong. My old E70 3.0d (bare in mind it was tuned to 340hp) covered just over 300,000km before I sold it, hadn't had any big issues other than the rear diff, and regular services and small repairs. New owner hasn't experienced any issues issues either. They are built a lot better in terms of covering high milages than the F15, my friends M50d's turbos failed at 20k, and another guys M50d engine failed at 40k...

I have had a 2006 530xit with 182,000 miles that has been running fine without major problems, presumably with the original engine and transmission.

My last X5 3.0 not turbo had 155k on it before it was totalled. Perfect engine.

For those E70 owners with 3.0 engines that did go 200-300K KMs, what kind of preventative maintenance (if any) was done to the transmission and/or differential?

At 250,000 on my 3.0d, my rear diff failed. I replaced it with an X5 M diff. Bare in mind it was tuned to almost 100hp more than what it was from the factory and used that power on a regular basis, so the fact it failed is understandable. Transmission is still working perfectly for the new owner at 300,000, just regular fluid and filter change / service... whereas on my 03 cayenne S, I had to have the whole gearbox re/built at 100,000...

The 100hp increase was achieved by a remap, bigger intercooler with stronger piping to handle the boost, and a turbo re-build.

With Mine I changed all the fluids @ 100K also with the transmission I changed the plastic belly pan as the filter for the transmission is in the pan.

10 miles from the big 100k, replacing the radiator this weekend. My only leak (currently) is a small coolant leak from under the rad. :)

114k and counting on my '11 X5D.

Purchased in July w/ 102k on it. Changed trans fluid, rear diff, couple of oil changes, coolant was done when the t-stat was changed, power steering (hydraulic) fluid changed, brake fluid changed, new battery.

Unrelated to engine: New tires, upper control arms, and alignment. About to do pads and rotors all the way around.

OP is asking about 3.0l gasoline engine, which is believed (by some) to work overtime in - let's be honest,- quite a heavy car, hence the expectation (again, by some) that it wears faster than in other applications.

I was happy to see such high mileage on the diesel engine X5's! Still curious about the gasoline engines too

:thumbup: Thanks for all the responses!!! Keep them coming. I know there must be some real high mileage X's out there.

Search auto trader and sort by highest mileage. 2010 x5d 244,000 miles in CA for sale :)

2011 x5 35i with 120K

Well I am about to hit 110,000. Took a trip to Middleburg VA., wine country to pick up some vino. Beautiful place out there.

Mines is at 110,000 miles now. So far I have replaced
Ignition coils 75k - One went out so i replaced all of them along with spark plugs
Rear air springs and compressor - 90k
Starter -95k
Original oem battery - 101k
Idler pulley - 103k
Valve cover gasket, front crank seal, AC compressor,AC Belt -110k
Blower motor and final stage resistor 111k

Oil change every 3k miles and just did pads and rotors too

With the exception of the compressor I was able to to do everything myself. Labor on ac compressor and belt was 300.00 usd.


Thanks to everyone on this forum i was able to save money on labor.

100,000 E70 6
 

I just purchased a 2007 X5 3.0si with 111,500 miles on it. The Carfax was clean and the car was maintained by BMW all the time. Prior to the purchase the evaporator in the car for the air conditioner had to be replaced. Paid for by the dealer. The EMF switch was broken (fixed that), the top of the glover box was coming apart (fixed that), cigarette hole in the back seat (fixed that). My Mechanic checked it out and all it needs is tires up front. Everything is tight. Electronics works fine.

I have a 2003 M3 Cabriolet with 181,000 miles on it and it runs strong. We looked at the valve area and it was clean as a whistle, like new. There was no indication on the Carfax that the engine had been changed.

I believe in the 6 because I worked on them in the 70's. The engine is fine, it's what's around it that is the problem if any...

I love my 6. I used to be a V8 guy but I have fallen in love with in-line 6's for awhile now. Everything I need plus better gas mileage.

Would like to contribute - 216,000 Miles on my 3.0

I do not find the engine to be underpowered, but I could see that being a driver preference, I certainly drive on highways but do not feel the need to pretend that my 2005 SAV is a Tesla...

I have been enjoying the car fully, hope to take it up to 250k and beyond! will write back as I cross those milestones!

196k Miles.

Cats are going out..

Any specific codes making you say that? I too have emissions related codes that I have tired some amount of trouble shooting but eventually just assumed it to be cats (216k on original cats)

Have been getting these codes the last few months. Although, using Cataclean the chrck engine light went away and I was able to get the car to pass smog.

P0430
Catalyst System Efficiency Below Threshold
P0420
Catalyst System Efficiency Below Threshold

Cats have a life expectancy, of course, but they are very durable. Poor mixture control can cause early issues. Related codes absent of other issues can be caused by vacuum leaks, exhaust leaks, bad or failing O2 sensors, and a multitude of other things.
