Re: stuck door!

after much wailing and gnashing of teeth I finally managed to gain entry, without breaking anything. I would never have guessed at the correct shape rod unless I have another door internal to look at, and furthermore when used as intended, it turned out the rod changed shape, so that it needed reset...

Re: M6 E24 Engine cuts suddenly

it could be one of several things but this behaviour is exactly consistent with a failing main relay.

Re: More sensors - which ones are these...?

a good way of testing for air leaks is to (carefully) introduce a fuel external to the inlet manifold at tickover; this might be lighter fuel or gas from a cartridge; anything that you can direct to a specific location really. When the fuel is sucked in a misfire may disappear and the at the least t...

Re: More sensors - which ones are these...?

one of the wires will be the oil level sensor but the others I'm not sure about. The sensors that make your B35 engine run are a) the front crank sensor and b) the cam phase sensor (on one of the plug leads) these don't normally go bad when the engine warms up but you never know. Some common causes ...

Re: Damaged sensor ID - Thermo time?

you have got no 7th injector and no thermotime switch on an E24 with the M30B35 motor fitted (~7/87 onwards). Check the wire colours against the wiring diagram to be sure but I think the two contacts in that fitting are a) the sender for the temperature gauge in the dashboard and b) the switch for a...

Re: No fuel injector pulse?

the speed and position sensors give different voltages when you use a DVM because the former creates a continuous series of pulses and the latter generates a single pulse per crank revolution. If you want to test them properly then you ought to use an oscilloscope, but that they measure the correct ...

IIRC the 008 ECU was used on non-cat motronic 633CSi from sept 1981. Maybe you answered this in a previous post but -when cranking, have you got the 'start' signal at pin 4 on the ecu…? If not this disables the motronic system; I can't remember offhand if it disables both spark and fuel or just one ...

Re: Electric fan - radiator cooling

if you unplug the wires from the sensor (which I think is on the RHS of the radiator and has three wires on your car; earlier ones are different) you can connect the wires using a jumper and the fan should work at both speeds. Alternatively you can put a jumper in place of the relay (s) and test the...

Re: Electrifying my '85 635CSi Euro

thanks for the reply. Yes it certainly is challenging and there are complex issues.

One of my mad plans is to have momentary action switches to run the fuel pump and ma...

Re: Heater valve repair

IIRC the 'no heat at speed' symptom is usually a small leak in the diaphragm. At low engine speeds the valve can work even if there is a little damage, but at higher (engine) speed the flow conditions in the valve change and any tiny fault is more apparent. FWIW the valve works on the pilot principl...

Re: Heater valve repair

my POV on this is that the MTC kit is so cheap it is worth a punt. You definitely need to reassemble the valve with all the same parts as it came with originally, which means yes you need the washers etc if the kit comes without them. I've seen more valves that have been 'repaired' badly than I have...

Re: Heater Won't Blow Hot

the first thing I would do to check that the heater valve is signalled to be 'open' when you want it to be hot. With the ignition on the valve should click (not very loudly, you won't hear it inside the car) when the heater dial is turned between hot and cold. If this doesn't happen there is a fault...

Re: Fuse 23 Blows Instantly

you may be able to track down the fault by simply disconnecting sections of the wiring harness selectively; preferably this would be by disconnecting plugs but if push comes to shove you will have to cut wires (in places where they can be rejoined easily of course). Another route is to use a bit of ...

Re: brake warning at 3000 rpm

if the ABS light comes on at about 75-80mph then it normally indicates that one of the rear sensors is failed or at least the rear sensors are not sending 'clean' signals (eg because the toothy rings are not perfect, or there is too much rust on the sensor, which is magnetic).

Re: No Start - Cranking - No Fuel - No Spark

if you have volts at one fuel pump and not the other, it most likely means that the wiring (at the back of the car) is faulty, since they are fed by the same wire and should both run at the same time.

did you get the correct battery? The correct one has a flange at the base. If the battery is the wrong size and/or lacks the flange at the base, the clamp can't possibly work as intended. A typical BMW battery with flange at the base; https://i.ebayimg.com/images/g/6MEAAOSw7ilci9tW/s-l300.jpg cheers
