Problems / Re: Broken E53 3.0i Rear Diff
« on: Yesterday at 05:48:10 PM »
33107510656 shows on Realoem as a remanufactured final drive for an E53 3.0i.  655 looks like a typo?

The part number is correct as BMW use either 7 or 11 digit codes and the last 7 matches the last 7 of the 11-digit format.  Ignore anything after the /.

Listed as $1600USD so probably a 1:1 conversion plus VAT  :o

Yes.  Alternatively just take the key out and wait 16 mins with the doors etc open.  It will still go to sleep.  :)

Are you using the web address above?  It’s certainly accessible on that url.

We would go auto and 2.0d...nothing less.  The Active Tourer is No2 at present, with the X2 in third.  I do like the X3 but the economy is well below what is practical.

We may be in 1.3 CVT Honda Jazz for a while (don’t laugh, it’s free!) - which I will live with for a while.  :))

The problem is that some of the fuses (and there are two boxes) power multiple systems and some systems have multiple fuses.  First thing to check is what the ‘asleep’ current draw is to prove whether you actually have an issue to chase down in the first place.

You can also end up pulling a fuse which then wakes the car up - then you have to start all over again!  It can be a real pain tracking these issues.

That device will tell you what is on the circuit so is of use  :)

If you can get hold of the last 7 characters of the VIN then use one of the BMW vin decoders on line, you should get the build spec ‘as built’ and you’ll see what the car was built with.

And :hi:

MSport mudflaps have been an issue for years, with none being offered by BMW.  Not sure why there is an issue with that trim though.

TBH they won’t make a significant difference anyway as the tyres are so large they still throw plenty of crud about.

That just resets the throttle adaption, it has no effect on the box itself.  Will it move in ‘Manual’?  Sometimes they do which might at least get you to a specialist (though trailer recovery would be safer and cause no more damage if there is any) who can read the fault logs to see what is recorded.

BMW are just in the process of updating the B47 engines to the B47TU1 (twin turbo) which will improve economy, efficiency and reduce emissions at present - which is why the configurator currently has no diesels on it much to my annoyance - so that they meet the new EU6c standards required from the start of 2019.  The cars will also now need AdBlue to meet the regs.

EU6c is much tougher and covers real world tests rather than just lab tests.  Much tougher cold and hot start cycles are included - cold starts being an issue for diesels and overly ignored in earlier regulations.  I have no problem buying another diesel and the X1 is currently top of my list (the road tests for the 2.0d X3 real world mpg falls below what my X6 does at just 33].

The new regs make it very clear that the EU know it could have been better at checking, and that the car industry did not do as promised.  Surveillance will be increased and even tougher regs are due a year later.

Petrol engines are fine in smaller cars but as soon as you get into anything larger and need to commute 15k a year as I do then they the cost is too high.

Diesel will have to stay in as the CO2 rules cannot be met without them - and electric as yet still isn’t good enough on range, with inadequate charging infrastructure likely to be in place for at least another decade or more.  We don’t have enough generating capacity or distribution capacity to meet the demand either on National Grid or to houses.

You can get an official diesel system/injector cleaner from BMW - Coltswold BMW sell it on flea-bay at a good discount, and they are on here as coltwoldbmwmini too.

Send Jason at jason@bwchiptune (also on here) a PM if you want safe and sound advice about remapping.  He knows what he’s doing and can 3xplain the do’s, don’ts or shouldn’ts as well as any risks.

The car does need to be asleep so that you can confirm the current draw.  You don’t need to sit in it but you will need access to the boot because you will need to disconnect the negative from the battery in order to measure the current flow.

The circuit tester sounds like all it detects is a blown fuse and that is all. It won’t tell you the current being drawn from the battery, that needs a meter in circuit at the battery or a device called a current clamp (it measures the magnetic field that the current generates to give you a reading).  The clamp simply goes around the battery cable (usually the positive) and you don’t disconnect anything.

It is a known problem and a number of folks have had it.  If the actual actuator has failed then BMW will just replace it - and they are over £700 last time anyone reported it.  There was a thread on here, and possibly YouTube videos in diy a repair.

Given the emergency release didn’t work, it might be a fault at the drum brake unit on one side rather than the actuator.

There were two (legitimate) ways.  You need a new licence key from BMW which were nearly £200 and either a set of DVDs or a set of USB keys with the map data also from BMW.  The last time I did it the map discs were £25.  It takes about an hour to load the data so you need to either be driving the car, or have it hooked up to a large charger as you need the ignition circuit awake to keep the iDrive awake.  The system will then update the maps in the background (which can take a while too) whilst giving you the old maps and then rebooting.

The licence key (FSC Code) is based on your VIN and you enter the number into the iDrive.

The little orange LED next to the ‘P’ symbol will tell you if the car has gone to sleep (it goes out).

I would be very surprised if the CTEK device draws very much at all as it is only a small bit of logic and a flashing LED - so a very few mA at most.

Cold weather will lower the capacity of the battery and I find the CTEKs a bit pessimistic overall - but that saves you getting caught out.

I wrote this back in 2012 (Post 2) covering how to check the current draw.  It should be well below 100mA and preferably below 80mA asleep I think.

Unfortunately the most likely issue will be either the torque converter or gearbox itself unless your trans fluid level is too low to maintain operating pressure.  It will go into gear but without enough pressure it won’t move.

You’ll need to get underneath to check the level (car needs to be kept level too) and also check the colour and ‘smell’ of the oil.  If dark brown and burnt smelling then the couch and brake packs are slipping and the friction linings will need replacing.

Should it be a box issue then you are looking at £1,500 upwards for a rebuilt swap out.

The E53 is known for transmission failures (I had one myself with no warnings until far too late).  Mine made nasty clanking noises before losing all drive.
