Wow this I recently delt with, there is a weird way to reset what bmw calls the lockdown mode or something like that, you use the key in the passeger door in a certain way. find a shop with michell1 or call the dealer and they should be able to tell you. but this is only if you particular car has entered this manuel lockdown mode. I found this strange as the bmw i was dealing with according to mitchell1 actually manually takes the door lock linkage apart in the lock assembly so that the alarm computer must be reset for the locks to function even manually!!

your asking me something now ,havent seen one in years but the cables can be connected over with time and patience and a bit of solder is good as it doesnt corrode ,now the ballast resistor fitted with the siemans was a different type of circuit and as it was a bosch then wire it as the bosch was wired ,because the ballast resistor was used in conjuction with a 9v coil and when you cranked the engine it allowed full 12v voltage to the coil to give an increased spark under crank load ,never did work that well to be honest and the resistors often packed up so use it as the bosch system .On the siemans you had a wire from starter connection on ignition switch to coil and the ignition feed went through the resistor to the coil ,Simple enough but them resistors were a right pain in all honesty

It has a timing CHAIN, not a belt. ALL BMWs have timing chains, unless it is an OLDER BMW, which only then might have a belt-driven timing.

could be a few differnt things, start with the obvious and least expensive, check the fuse, and relay for the blower motor, if they are good, move on the blower resister. and if not the resister id say the blower went, but most likely one of the first two. hope this helps you

Siezed pumps are a nightmare.

Spray with penetrating fluid, let that soak for 5 minutes then use a length of 3x3 wooden post and hit hard with a lump hammer. It will eventually break out.

The pump is alloy the block is cast so you'll be fine.

Hi Mountview,
First thing I'd suggest you do is delete the fault codes from your scanner....The engine management computer stores them, and they may be from your old engine?
Run another scan and if the codes come up again check the cables to the sensor. Defective parts are not unknown, especially where I am....
The anti theft device may have kicked in and be inhibiting starting....This will require resetting on your scanner.
Once you've checked all of that, bleed the diesel system, as if there's any air in the fuel line, it won't start

Sounds like a rely or fuse, check you manual for the fuse box location and then check the fuse for the horn. If the fuse is good, check for votage with a voltage meter at the horn when you have someone else honking it and see if you are getting 12 volt to the horn itself. If you are getting voltage then the horn itself is bad. Sometime just tapping the horn can make it start working again.

Have you check the THERMOSTAT VALVE?

Jambo. Can you turn the steering wheel? If it has locked the wheel, you are going to need to break the lock cylinder with a hammer and screw driver and turn it. If it is free, you can get under the dash and use the wires to start the car and replace the ignition cylinder later. Use this diagram if you need. Feel free to let me know if you need anything more.

is it just idling roughly or hesitate when accelerating? You may have a clogged cold start injector in which you could have poor performance before the vehicle heats up to its operating temp but once it reaches its peak temp will run fine. Did your servicing include a tune up and/or fuel system cleaning if not I would recommend one.
