Ok this is a very weird problem. I replaced my main windshield washer pump with a new OEM unit because the old one was leaking.

Now, the regular washer spray is just like the "intense" washer spray....e.g. the liquid comes out of the nozzles in a hard, straight jet instead of a gentle spray that fans out over the windshield like it used to. This is bad because I need the liquid to fan out across the windshield to actually clean it instead of just hammering 4 clean circles into the windshield ****.

What in the heck happened? :dunno:

I presume the pump hasn't got an adjuster for pressure etc???

No, not as far as I saw when I looked at it. Oddly enough, the part #'s for the intensive and the regular washer pumps are the same. Shouldn't they be different?

I don't think I ever had a gentle spray, especially after I replaced all the lines and the pump on the main reservoir.

The pumps are identical on mine. To my understanding the "intensive" system is less about power and more about the special no longer available (flammable *****) liquid that it used, plus its reservoir tends to be warmer as a by product of its proximity to the engine. Intensive does double up on the amount of liquid as each sprayer has one hole for the regular system and the second for the intensive system.

when I first bought the car, with 86k miles and the original washer pump, the spray was like any other car's....a wide spray pattern that covered almost the entire windshield with fluid. The intensive fliud always shot out like a friggin cannon in straight jets....like my regular washer pump does now.

Maybe I only got the gentle spray because my original pump was worn out after 86k of use? That's odd though because my friend's E46 M3 sprays just like mine used to. Hmm....

On my car, the pressure was the same between intensiv and regular...but which reservoir it draws from is different. I think they meant intensiv because the fluid it uses is very high in methyl alcohol compared to the 1 bottle:4 gallon mix they sell as regular washer fluid.

Would love for others to chip in with their experience. The part numbers are the same on RealOEM for the pumps.

I've replaced the main reservoir pump, filler hose, the washer lines (set has both intensive and normal) AND one of the sprayer nozzles. Other than having to AIM the nozzles a bit down so as not to douse cars behind me I haven't had any issues with function and this setup is pretty much as close to new as you could get.

 

[Mfreakin5]

Since you guys are saying that your spray intensities are the same, I'm guessing my initial gentle spray was just a weak pump.

If that pump wasn't leaking I'd put it back in there in a heartbeat! The washers are pretty much useless now.

I kind of want to swap to E53 X5 nozzles. They dont squirt in two hard streams, rather they fan the washer fluid evenly across the glass.

 

[Mfreakin5]

that would be awesome.....the X5 nozzles are $25 each....any idea if they would fit?

That's what I'm not 100% sure of. I guess I could pop one off my X5 and try it on my M5 if I werent so lazy

Straight jets here, no fan effect.

Mine come out in 4 jets but the wipers quickly spread the fluid and clean the whole windshield. Your wipers are coming on? dumb question but covering the bases. Have you seen this on proper adjustment of the sprayers. The washers work great at a stop light or at 160kmh. have you seen this?

 

[JustinM5]

Measurements for where the jets land is going too far for me!

This is how I have mine adjusted...but I'd rather have the fan pattern. Better for soaking the nasty lovebugs we get here before they get wiped off.

Based on the below I'd say no, the M5 nozzles have TWO nipples each, one for the regular and one for the intensive lines. The X5 nozzles only have the one line. Who knows on the physical fit and electrical connections.

Think it was an old audi, had powerful fan that covered whole screen, must have used a gallon a second, bloody great that was.
Not seeing the road for a second or 2 wasn't so hot but still...

Awesome diagram Sailor, now I have a project for this evening. How incredibly German of them.

 

[E55AMG2]

Just ran out and checked. M5 def has dual nipples. Cant see why they couldnt be tee'd into a single setup though. Hmmmm

Yeah I noticed that too but I'd simply disconnect the useless intensive spray lines and be happy to have a useful washer spray pattern. Or maybe run the X5 nozzles just on the driver side.
