New to X5 - Few questions

Hi all,
We bought a 06 X5 (E53) in Feb. It is a 3.0D auto.

I have a few questions/issues.

1. The rear tires are wearing on the inside edge, which are nearly bald, while the outside edges are nearly new.
Is there any way of adjusting the camber?

2. My trip computer said fuel usage was 11.9 l/100km, but when I filled up and checked, it worked out to 12.6 l/100km. Is this a known issue? An adjustment needed?

3. I need to change the ATF. We have the ZF transmission, and although I have searched here and seen pictures of what my tranny should look like, I can't find the filler plug anywhere. My tranny looks different to the pictures on here. Our tranny has the plastic pan. Any suggestions of where to look?

Thanks for any advice.

JG

I'm new to the site myself but I did find on the (e53) forum a "how to" on your transmission. If you go to the main thread about halfway down on page 1 is the step by step post that was done a bit ago. Sorry but I haven't figured out how to post link to a link yet, but hope that helps!

Welcome to the party.


1) That tire wear sounds like bad rose joints. You check by unloading the tension on the suspension by placing a jack under the rear spring perch. The rose joint is at the rear end of the lower arm. Replacment can be done with a special tool.


2) Factory consumption calculator is usually a bit optimistic. Nothing you can do about that.


3) No info on this one.

Welcome Jughead028

1. More than likely will be a control arm that is bad.
The e53 does have a decent amount of + camber, but shouldn't cause that much wear.
Could be either camber or toe is out of adjustment. Both can be adjusted on the inside part of the wheel carrier where it connects to the subframe.

2. Agreed BMW is usually optimistic on this. As long as the factory tire size is correct, that's just the way it'll be.

3. Looks like the fill plug is on the side of the tranny just above the pan.



Be aware that the drain plug might have a plastic cover on it to protect it.
On my 2006 4.4i it was black plastic which made it difficult to notice.

This gives a full teardown of the tranny.

This is less of an issue that what you think or it appears to be. If this is your first time checking the difference...the difference is only 0.7. If you were to keep a chart...you'd probably find out like I did...that when both MPG's are charted...when averaged over a period of time...they really aren't that far apart.

I keep an Excel chart of every fill up and the "actual" MPG vs the OBC's MPG hardly ever are the same. But tracking of each and averaging them over an entire year...you can see that they really aren't that far off from each other.

In the chart below from 2013...note that the year end total is 14.47 MPG for the "actual" mileage (tank miles/gallons) and the year end total for the OBC is 14.84 MPG. That's only a difference of .037...which is a very small margin:

The consumption seems very high - I get less than 7l/100km on a trip and about 10l/100km around town. The average is close to what BMW say - 8.8l/100km.

Your auto trans fill point is next to the drain drain point on the bottom of the pan. The ZF auto on our 3.0d has no fill port on the side.

Yeah what wpoll said, my average is around 8.5. Never got less than 7 though! Worst i got was 15.8litres, towing 3t through some gnarly hilly country.

Hi Jughead028, welcome to Xoutpost!

Sorry for the slightly brusk earlier response, I was out of town for the weekend and in a location with very limited internet access. Just arrived home, travelling mostly over the South Island's Highway 1 at 90-100km/h and the consumption is showing 6.9l/100km. Traffic can be a little slow on a Sunday arvo!

So.. yeah, firstly it seems your consumption is a little high but that can be dependant on many things, including the weight of your right foot. And a heavy right foot can also contribute to your rear tire wear too, as it happens....

Things to check on your (new-to-you) diesel are: -

Air filter - if it's an unknown quantity, replace it. And watch a YouTube clip on how to do this, as it is rather a mission to do on our 3.0d models - no kidding. Best YouTube clip I've seen is from your neck of the woods...

https://youtu.be/-LXBlUlgTjo

I don't bother to remove the windscreen washer bottle - it's not in my way usually.

Engine breather and oil recovery assembly - again, change it if it's an unknown. Also shown in above video. The older loo-roll filter type clogs very quickly - don't use this type, get the vortex-type as shown in the video (mine had the loo-roll but your '06 should have the vortex-type). You'll need gaskets and oil recovery unit (vortex thing) as a minimum.

EGR - clean it out. There lots on info. online about how to do this too - like this: -

DIY Removing EGR valve and air filter on BMW e39 530d | BMW e39

Removing the EGR isn't as simple as some folk make out but it does stop the intake getting fouled with carbon. Removing it won't help fuel economy. Up to you - I've left mine in and I've seen some disasters caused by removing it...

So, on to the excessive rear camber. Yes, this can be adjusted out. As long as your rear suspension is in good condition. Once some of the rear bushes become worn, the rear camber tends to exceed the amount of adjustment and so sorting it requires the replacement of a few of the rear suspension components - then adjusting the rear camber.

There are tonnes of discussions in this forum on this subject!

BTW, note that it is best to always replace all four tyres at once, as it's important to keep the diameter of all wheels within 1-2% of each other. Failure to do this can result in damage to the X-Drive transfer case.

Transmission refill. Use ONLY ZF Lifeguard (or close equivalent - YMMV) in a ZF 6HP26Z as fitted to our LCI E53 3.0d. Anything else has been found to cause transmission problems.

Filling the trans via the fill port on the pan is a minor mission and requires an fluid pump.



I think Ohsoslow and at least one other Kiwi have done work on their trans and have posted some great info. on the whole process somewhere on Xoutpost. A minimum would be fluid, filter, mechatronic seal, bridge seal and four jump seals, if you're going to open her up.... at least that's what I plan to do when I have to open mine up (one day...).

HTH... :-)

Found one of the posts I referred to in my last post...

https://xoutpost.com/bmw-sav-forums/...hatronics.html

I also corrected my statements about the location of the fill port - I had stated that it was a shared drain/fill port but I was thinking of the last VW transmission I had worked on (on a Golf Mk.V) - the ZF 6HP26Z fitted to the 3.0d has two ports in the pan, as per the image I've added to my earlier post.

Thanks to all that answered.

And wpoll, no worries about the "brusk" reply. I did not think anything of it, even after you mentioned it.

I have located the fill plug, exactly as in the diagram above.
Now I just have to get the tools to do the job.

I will look into the suspension issue - maybe take it to a professional (Pedders).

And, yes, I do have a heavy foot.
When we got the car, the fuel consumption was showing 9.0 l/100 kms.

But we use the car mostly for short runs - less than 10 kms a trip.
When we use the car for longer trips, consumption goes down to about 9 or 10 l / 100 kms. But even this is about 50% freeway & 50% city driving (very heavy traffic).
One of these days I plan to do a long freeway trip of about 800 kms to see what I can get it down to.

Air filter - I just had the car serviced (log book service at 216,000 kms?) - shouldn't the air filter have been changed? Or checked at least?

Cheers,

JG
