Wiper pressure

You say that you put some anti freeze in the bottle a while ago, this may be the problem. It would appear that if you use some other washer fluids/antifreeze other than BMW recommenmded stuff it goes all gungy in the bottom of the bottle. If you have you need to take off the o/s/f wheel remove the inner wing cover and remove the whole bottle and flush it out.

My e39 leaks water from the bottom of the bottle when i fill it up with screen wash and i get the very same thing as stephen describes, powerful with the intensive but not so good with the normal jets?

I think i asked about the washer bottle before on here and i had a few replies saying that the bottle on a few e39's leaked when filling up!

I would suspect that the pipes do get gunged up and may try the wire in the nozzles myself once it warms up a bit though

was the underbonnet sound proofing damp?  i had that on my e36 - blocked t-piece to the jet caused the rubber pipe to come off and soak the underbonnet felt

Come to think of it, I do remember water leaking when the car was stationary.

Also any idea how to get to the washer bottle filters and as stephen has mentioned the connectors?

cheers

Mine went awol late last year, took it in to my Indy who identified that the connectors had come lose, but visually all looked okay.

It was only when the pump was working that water was leaking out under the car.

They also cleaned the washer bottle filters as they were clogged with an until then undiscovered life form !!!

Also wax and polish can get in to the jets and start to build up and block so do check those are clear as well.

Is there some sort of in line filter on the system? Reason I ask is that on mk4 Astras they have a filter which is located up in the inner wing, and this clogs up fairly regularly making the washer jets somewhat akin to a grasshopper sneezing. The washer tank on most cars ends up with a layer of scum,some of which will end up in any filter that is fitted. Have a hunt for that after clearing the jets.

I have asked that question to BMW but they have said that is not the cause, and won't tell whhat is causing it, until I pay them diagnostic charges which would cost me about £100 just to know the problem.

One of my mates is a mechanic for VW and he suggested, that the pipes connected to the bottle sometimes clog up with some algy/alky and they might need cleaning.

But I would prefer to leave the long option till the last moment.

I will try that first thing in the morning

until then more ideas welcome. Better to try all of them together.

 

cheers guys

The wipers are working perfectly. it is just the spraying system. Somebody did suggest that there might be a hole in the bottle.

Got that checked and it was fine. I am not whether the relay has something to do with the pressure of the water?
