E30 Connectors to wiring headlights and washer bottle

[RTTBMW]

Hi all,

Looking for replacement connectors as per pictures below! They have become brittle! Can I still get these! Also the black inside bits as wel!

Hi mate, try Jon at Cotswold on here.

Wow I want your washer fluid tanks. So clean

[RTTBMW]

I replaced the tanks as the old one was ruined and a piece of plastic broken that holds the AHO-Motor to the bottle! I did a few things including the coolant bottle (Mine was pure black), Fuse box lid and few clips. I am replacing the piping to the washer nozzles as they are brittle and leaking water everywhere! I have just finished repairing the Headlight washer wipers and missing nozzles! I also replaced all the light adjustment screw/bolts as they where seized!

[RTTBMW]

Ok! I have found the correct connectors

61131378406 is the female connector I need in grey! The other one is 61131378418. It is grey too! I have made up a list of connectors and their colours! So I will probably expand my purchase of connectors to replace the brittle ones!

Could do with those myself - added to my list for down the line!!!

Any idea how it works???
Two 'bottles' with sensors, but only one coolant level light in the car?

Recall mine not working and being constantly lit, however, on getting the car back on the road, the light wasn't on (empty reservoir) and topping it up has made the light come on, so something must be the wrong way around!!!

There's a current thread on this in Cotswold's forum, and get that 15A fuse for the fuel pump replaced by the correct 7.5A one, before we get a "why has the wiring loom in my E30 gone up in smoke" thread!

Level sensor only works on the larger tank. You only know that the intensive tank is empty when nothing comes out of the washer jets.
Level sensor fits into a round hole with no locating peg of any kind, so is free to rotate. If it turns upside down, light will be off when empty, but on when full. Pins for the plug should point straight upwards.

Excellent, thanks Brian!

Should you have small reservoir blue cleaner and large one water?

Or as in the picture?

Put what you want on your headlights in the small tank and what you want on your windscreen in the big tank.

Not so! Headlamps and screen are both washed from the large tank. Small tank should have a concentrate in it, and is only used on the screen.

[flybynite]

Small bottle connected to the lights on mine but it would explain a few things .

[RTTBMW]

Ok I'll change that at some point! I'm doing those connectors later today hopefully when Paul turns up!

[Sanchez]

I’m refreshing the front end and washer wiring is all up the hoop.

Haynes manual has given me the wire colours to do each pump, I’ve not got grey connectors but blue and broken fragile wires so cleaning it all up.

One headlight wiper motor working so getting there.

[RTTBMW]

One of my wash wipers stopped working all of sudden! I am going to have to check the voltage and connections again! Those valves to the hoses from BMW are a waste of money! They split very easily!

I ordered a valve from BMW Classic recently and it arrived split - they really are surprisingly fragile. Disappointingly, the BMW hose you now order is just gloss black - so doesn't match the original hoses. First world issue obviously

i had the same with the T valve for the washers from bmw,
sorted it with a thin bead of clear gorilla clue round the edge, been ok ever since.

This is fairly common with genuine parts. 'Genuine part' means a part that will do the same job as the original, to the same or better standards (doesn't seem to apply to some body panels), not necessarily a part that is identical to the original.
If it's any comfort, the black washer hose was OE on the very last of the tourings.

Haha - that will definitely help with my OCD, although it means I need to replace more of it now!

[RTTBMW]

Well today I drove the car and it is running smooth as a whistle!

However, one one wash wiper (Headlights) is working. The passenger side! I asked Paul did you wire them the wrong way round when replacing the connector switch! One of the reasons why was when I put the ignition on the passenger side washer would turn on! Driver side dead as a door nail! So I swapped the wiring in the connectors round to see if that helped. Nope! Both did not work at all. So i swapped back the connector wiring! Back to square one! Now these wipers were working before the connector broke! Would the wiper be sticking as the odd time I would have had to move it manually to get it going! Car has been sitting since last October in the shed!

And I checked the nr 5 fuse! 30amp! Replaced it to be sure!

You've lost me a bit here! There's no direct user control of the headlamp washers and wipers. They are controlled by the mini ECU attached to the side of the washer bottle, which operates them every fifth time the screen washers are used when the lights are on.
There is a permanent 12 volts live supply to each wiper motor when the ignition is in positions 1 or 2, and they are started off on their sequence by a short 12 volt + pulse on one of the other wires. Once they are started, they operate totally independently of each other and their individual wiping sequence is controlled entirely by an internal cam and switch in each wiper, stopping wiping when the cam switches off the switch.
The right hand wiper contains a second cam and switch which operates the headlamp washers.
The usual cause of a non working headlamp wiper is that the output shaft has seized inside the long bush that also serves to mount the motor. There should be a small rubber O ring on the shaft at the front of the bush, to act as a seal, but these have usually long since disappeared.

Be interested to know what they cost when you get the prices.

Brian, are you saying the left motor and right motor are slightly different to each other! These are refurbished wipers! Your right motor is the driver side are you referring to? My motor on the drivers side has an R on it!

LH motor has three wires, RH motor has four. The extra wire is the feed for the headlamp washer motor.

[Sanchez]

Most failure of the motors if found it the shaft seized inside the long threaded tube.

I have not seen a dead motor or broken gear tooth yet.

[Brianmoooore]

I have not seen a dead motor or broken gear tooth yet.

There's a PTC thermistor ( a grey circular disc) in series with the motor inside the gearbox housing, that limits the current to the motor when it seizes, protecting it from burning out.

[RTTBMW]

Okay I'll check this out!

Hi RTT,
Where did you pick these up? I could with replacing mine too.

yes I was disappointed as well I've just replaced my bonnet and thought I'd replace the washer hoses etc , as you say they now come in black .Perhaps i'll have a go at cleaning the original pipes.
