2006 X5 M57 Mainenance

Recommended Posts

So having picked this thing up a couple of weeks ago, it's time to go right through it and service everything so I know everything it up to date. It'll be getting a fresh service, new air, fuel and oil filters, new oil etc. What other things should be on the list?

Would it be a wise idea to change transmission and transfer case fluids? Diff oils? 

A few issues that I have noticed - first, on cold start, there is a very small cloud of smoke from the exhaust - only happens on cold starts, doesn't smoke at all when driving. I'm thinking this is normal?

Temp gauges normally sits between 1/3 and 1/2, which seems a bit odd to me (should normally be around the 1/2 mark I thought), handbook claims this is normal - is the thermostat worth replacing?

I also get a diesel smell when it's cold, I've been lead to believe these things have a small auxiliary heater that runs off diesel to get heat flowing in the cabin quicker - is there some way of eliminating that diesel smell? A filter or an exhaust somewhere that could be blocked on that system?

The last worrying thing is a whistle from the turbo - definitely worse when cold. I'm hoping some new oil will sort this, what else should I be looking for before panicking? I'm assuming the standard leaks and potentially bad gaskets/hoses? Any common problems people are aware of? 

All in all, it drives well, has a ton of power, there's no real vibrations or noises (other than those noted above) so I think it should last a while with some TLC.

I change all fluids and filters on every car i buy unless i can confirm its been done when specified. 

Should be able check the actual operating temp via hidden OBC menu? or scan tool and compare it with the t-stat rating 

Is it just diesel combustion smoke? A full scan with intake and exhaust smoke test is probably a good idea to start with

I would change every fluid including transfer case unless there is service history so you can see when everything was last done. I do brake fluid, coolant, diff trans and engine oils whenever i buy a new car. That's just me though.

It's easy to tell if you have an auxiliary heater. It's under the bonnet on the passengers side and looks like this photo below.

 

If it doesn't have the auxiliary heater, it could be an exhaust leak from the engine/turbo area. The exhaust manifolds sometimes crack on the M57, so that's a possibility. Diesel fumes are quite carcinogenic so i would get this sorted ASAP if it's coming into the cabin. Turbo oil feed hoses sometimes block up and cause the turbo to fail. If you ever have the turbo fail, remember to replace the oil feed line at the same time! Other common items are upper rear suspension arms and front castor arm bushes. They're a pretty sound vehicle really. 

A small amount of smoke from the exhaust is normal on start up on these. The engine temp sounds a bit iffy from what you describe.  Maybe do a thermostat as well. How many kms has it travelled?

Yeah exactly why I'm planning on doing it sooner rather than waiting for the service indicator.

I scanned it with INPA before buying it, all stored fault codes seemed to be mostly lights and the steering angle sensor but I didn't spend a lot of time checking everything. Will have to have a play with the OBC menu as it's locked atm.

Seems to be just a puff of diesel smoke from what I can tell, and it's definitely only on a cold start.

It's got service history from Greys in Christchurch until late 2013, then an indy in 2014 which is when I think the original owner sold it, hence why I'm leaning towards changing everything I can.

Yep definitely has an auxiliary heater, I was wondering what that box was for lol just haven't had a lot of time to research things yet.

That's some great info thanks @NRJ, thinking I might play it safe and swap out the oil feed line while changing the oil just in case the turbo isn't quite getting enough oil, better safe than sorry, and check the manifold at the same time. And will check the suspension out when I can get it to my local and throw it on his hoist, though dare say everything that's ever needed done on this thing has been done by the first owner.

Yeah thinking do as @Eagle suggest and check temp through the OBC as the gauge itself could also be faulty, and if that's reading less than it should, a new thermostat will hopefully sort that. It's done some 355k so high mileage, however the first owner was driving from Mandeville to Queenstown and back (150k each way) 6 days a week so a lot of hot running, there's not one sign of any oil or fluid leaks anywhere and it drives and handles really well so I'm pretty confident that, apart from a few minor issues, it should last a few years yet, as long as I look after it.

Have run three m57 x5s for work and personal, all three ran fairly cool on the open road. All three had the smoke on first start up, nothing to worry about, likely failing glow plugs but I've never had a starting issue with all 6 dead 

 

The diesel small is most likely a cracked manifold 

The aux heater only works under 5 degrees ambient 

 

Do the PCV/CCV in the rocker cover, its extremely important on these 

Do the fuel filter every 50km it's easy enough and cheap  

 

1/3 to 1/2 on the gauge is 70-80 degrees, allnthree I've used run that low unless under load, my tuned one runs just under 70 on the open road

Thanks, yeah was thinking the smoke on start up was glow plugs but it starts just fine so I'm not panicked.

Will check the manifold first chance I get, would that possibly also be the source of the whistle? Seems like a plausible explanation as the whistle gets noticeably quieter when it's warmed up.

I did read online? operating manual? that apparently the diesel smell is normal on start up, and given I'm in Southland 5 degrees ambient air temp is basically summertime lol. The smell has been far worse when air temps are way down which is why I was suspecting the auxiliary heater. But will investigate the manifold first of all.

Will add PCV/CCV to the list, definitely a good idea to do it given the unknown history, thank you. And fuel filter will be getting done regularly, they are cheap insurance along with oil and air.

Ok good to know, it hasn't gone over 1/2 so not a major concern, will keep my eyes on it.

Ours have always smelled on start up.

My current one has no cats and a tune and makes quite a bit of turbo noise, it absolutely stinks when its idling too

 

Yeah being down that way I guess it will be having some smokey starts :D

 

the only consistent issue I have seen on the ones we have run is front outer cv boots fail like any other car. That's about all that has been done on them in 400,000km combined apart from regular maintenance (and 4 gearboxes in the PFL auto.. )

Check the error codes, that will tell you which if any of the glow plugs are down, controller for the plugs often goes down as well.

Change the CCV/PCV to the newer conical style if you have the old toilet roll type, as mentioned above this is a definite to change.

The fuel filter canister is often neglected under the floor of the car, suggest you change that for a new one as well.

Cool, CV boots aren't a major item so that's not worrying. Hopefully being an '06 with the M57TU issues like gearboxes are well sorted by now lol. What's it like decatted and tuned? I was playing with the idea of a tune for it but have heard the boxes can't handle much more than 500nm torque so that kinda put me off the idea.

There wasn't any error codes for glow plugs when I first scanned it but might be worth scanning again to double check. I'm thinking I'll change the CCV/PCV anyway as suggested, just for peace of mind.

I'm half thinking about putting a water trap on the fuel line as well, for added insurance, though that may be further down the track.

Right, off to start gathering filters and fluids, and might attack it all this weekend (if it ever stops raining hahaha).

Mine is manual so nonissue with boxes breaking haha it is awesome, pulls like a Vegan on a lettuce! Definitely faster than my 338 manual was and the torque is huuuuge 

 

The 6 speed zf auto is a great box, just get it serviced

Damn, might start looking into a tune as well now hahaha. Yeah finding someone down here that will service it properly and not charge what it will cost to replace it is the issue, but will have a hunt around as there may be someone in Dunedin that will do it (given I'm up there often enough).

Surprised no one mentioned replacing the drivers door carrier assembly...... as that decided to give out last night.... the rain sensor seems to have stopped...... and the alarm has started going off at random times for no apparent reason........ just hoping this isn't the start of a nightmare 😒😒😒

I'm still stoked with everything else, managed 7.8l/100k coming back from Dunedin last night with a bootload of stuff which I think is reasonable, so if this is the worst of the issues this thing has, it was well worth the money spent.

The door carrier assembly is pretty easy to do, I've done a few. One on my one. Enjoy!

Not sure if you have it, but BMW diagnostic software such as ISTA or INPA you can run a test to find out what component is triggering the alarm. It could be a faulty door or bonnet switch, or it could be the motion sensor inside the car.

Yeah got one on the way, removed the inner trim on Thursday night to confirm it was the carrier. Doesn't look too hard to do thankfully so will get that sorted.

I've got 2018 version of INPA, probably should scan it and see if it comes up with anything, just been too busy lately to spend time sorting it lol.

Yes was thinking that's what it is, a few times I've unlocked it and wiggled the bonnet sensor and it's behaved itself afterwards so will unplug it for now and see it that stops the alarm.

Other than that, oil, air and fuel filters have been ordered, oil purchased, new wiper blades and headlight bulbs sorted, so just about ready to rock when I get a day to spend on it.

You were dead right, bonnet sensor is unplugged and alarm hasn't played up since, so will be swapping it out with another one and see if that fixes the issue.

Oil, air and fuel filters turned up today, air filter already changed - what a PITA! Thankfully, somewhat slim hands helped lol. But what a difference, only taken it for a short cruise but immediately feels more responsive and economy seems to have improved as well, old one was black as hell....... shop vacc'd the area once the filter was out to clean up all the debris before fitting the new filter.

So oil and fuel next, then trans, diffs and finally transfer case and I think that's about it short term. Now just need to find a 12v power supply in the roof that I can use lol.

Yeah the air filter is a bit annoying. 

The fuel filter is a whole lot easier than the internet makes out though, if you have slim hands. Definitely worth doing too because nobody replaces them

Finally got around to scanning it again, glow plugs 1 and 5 had errors....... funny that they didn't show when I scanned the car before I bought it. But will look into it another time, far too much on the go atm lol.

Oil and filter changed today, so one less thing on the list to do.

Do either of you have any part numbers or an idea where to look in the ETK for the CCV/PCV/CVV (whatever it's called)? Having trouble finding any listing for it at all, let alone part numbers to cross reference. This is probably next on the list before trans service, transfer case service, then diffs.

Everything else I've seen under in so far has been in damn fine condition given the k's it's done. Apart from a few little creaks inside the cab when not on a decent surface, I can't fault this thing at all, and am sure with some TLC it'll do me the next few years easily.

Oil and filter changed today, I noticed earlier that the whistle I have when cold is a lot less noticeable than it was since changing the air filter, so perhaps the old one might've been that restricted (or a cover isn't quite fully sealing but is closer now) - so may just be air getting into a random tiny gap causing the noise. Will be interesting to see how a cold start goes tomorrow with the whistle.
