Bit late to this, but I was puzzled by the part in the image too. The outer handle is screwed in place via an access hole in the door edge. and it appears that this casting prevents the same hole from being used somehow to manipulate the mechanism when the door is closed. I haven't tried to break into my car, but its the only explanation I could come up with...

The Caravan Talk forum is awash with threads concerning BMW X5 additional cooling Q and A as well as the rights and wrongs of breakaway cable attachments.

Really? I visit CT most days and I can't remember the last time there was a thread about the  E53 X5 - which seems a fairly rare towcar choice. Search BMW X5 and you get zilch. Many people there go for Hyundai and Kia, sadly

My car is the E53 3.0d , fitted with a Witter aftermarket towbar and detachable hitch. The caravan is a twin axle 1900Kg. The car tows fine with no cooling or other problems.

I highly recommend the BMW mirrors as they are a doddle to fit, give good visibility and don't vibrate or wobble - expensive, but worth it for the lack of hassle.

I would also recommend using the BMW trailer module (plenty on Ebay) and the correct BMW harness from this to the 13 pin plug, rather than aftermarket wiring. Apart from being a lot neater, the module does a lot  of useful things like cancelling the PDC gong when reversing amongst other similar aids.

Modern towbars should have a dedicated eye welded on, in which case a caribiner type breakaway cable is a must. Looping round the towbar should only be done if there is no eye and then a clip type cable must be used. VOSA have been active in checking for overweight vans, defective tyres, wrong cable, wrong attachment and lack of mirrors - 4x4s are not exempt from mirrors - there are specified distances you should be able to see behind the van. Non -compliance  = fines and points.

Using a tie wrap to attach the cable is just downright dangerous - in a detachment, the cable is supposed to pull the caravan brakes on, then break itself. A cable tie is more likely to break first without doing anything at all

When you say silicone lubricant, what exactly is the product please?

Thank you for responding. I noticed the issue when the climate panel was set to MAX which auto sets the required temp to 16. I guess it is possible that the drivers heater valve is stuck, though my impression was of warm ambient rather than heated air being delivered. Still, that's a good check as its easy to do, except nothing was flagged up in INPA.

Problems / Air con air distribution
« on: May 14, 2017, 07:37:36 PM »
I thought my X5 needed a re - gas, until SWBO mentioned that the extreme left dash outlet was delivering well chilled air. The left centre vent is slightly cooler than its neighbour on the right, which has the same unchilled temp as the extreme right outlet. The car is not throwing any codes, and all the stepper motors look to be working on INPA.

So the chilled air seems to be there but not getting properly distributed. Any thoughts chaps?

Are you sure you tightened up the exhaust manifold correctly? Its quite possible to get a tick from a slight leak

Oh dear,  think i muddled up the wires on the heater,  i was tryng to get it going, i thought the 12v signal for the heater went to the centre block with the thick brown wire and red/yellow. i tried 12v on there but nothing.
now i found its the much thinner white green wire in the next block,  what are the 2 thick wires then , anyone know,  it did work for a few mins before i started pottering but now  12 v onto the pin 1 does nothing.  fuses ok. the pcb inside on top looks all shiny and newish but who knows. no signs of burn out, i tested the circ pump  at least that still works,  wonder if i have fried something,  :'(

The heavy brown is the earth. The heavy red/yellow is the main power supply. You should be looking at the oval 6 pin connector which is clearly marked with the pin numbers.

I have a Webasto factory fitted in my 2006 X5. I also fitted a petrol version in my '99 750, which is an even earlier Thermotop 'S' model, and required a huge amount of research, not mention the rebuild and installation

From the many images I have seen, the C and Z versions appear to be the same, and sometimes a unit has both on, with a Webasto label often Z,  and a BMW part no label showing, say, C.

For the E53 there is an auxiliary water pump, nowhere near the Webasto, but low down close to the radiator.

The PCBs have been problematic as a foam material was used to support capacitors on the board, and this attacked other components. Mine was not fully functioning, and I also traced it to the PCB, and replaced it with a repaired one off ebay, and no issues since.

As observed, the first time it fired up successfully, there was quite a lot of smoke that cleared after a couple of short journeys.

Do you also have an Intravee unit tucked away nearby? If an Intravee is fitted, and DSP is present, then a DICE unit is required as well. One connector from the CD changer goes to the DICE, but the second one goes to the Intravee.

You can get by just moving the airbag if you don't plan extensive work, but to answer your question, disconnect the battery and leave for 2 minutes before unplugging any seat or door plugs or any component of the safety system

It is easy. On later facelift cars, the very last fuse in the boot was not occupied by the self levelling electrics, so is an ideal point to provide a supply to a split relay. You should have 3 earths: pin 3 for all the road lights; pin 11 for the fridge; pin 13 for the live on pin 9. None of these should be joined on the caravan side-each wire must run to an earth point in the car.

You will finish up transferring your replacement seat covers onto the original divers seat frame. This because of the seat belt anchorage point, which makes the seat frames handed. Doing this will also avoid having to re-route the seat harness.

Remember to disconnect the battery, as the seat belt mounting has wiring to it that is linked to the airbag system

It's in the boot on the right hand side looking from rear. The fuse is the end green 30A.

It depends on the age of the car. On mine, the rear fusebox lists this fuse in this position, and I found a fuse there - except that only the live side connector was present, and the system is working fine, so there must have been a wiring change at some point.

The detachable tow ball usually has a key hole to lock it in place. so you normally have to unlock it before the push and twist release. If you have a genuine BMW unit, it will fit in the dedicated recess in the L/H boot floor under the carpeted lid.

However, the key is not especially sophisticated, so the hitch is best removed if you don't want to find yourself bidding for a replacement...
