I have been looking all over and still can't come up with an answer. On a 2010 528i..where is the wiper relay (61368384505) located? I looked under the left (driver) side pollen filter (removed the assembly that holds the filter) and nothing under there seems removable.

My wipers sometimes fail to park fully down when turned off. They rest about 2 inches above the full parked position. My research leads me to believe it may be the wiper relay. I also have a '08 535i, so I can just swap the relays to see if that is the problem. Of course, I gotta find the relay first...any help is appreciated.

You didn't go far enough. It's in the DME (ECU) box which is under the cowl on the passenger side, pretty much below the passenger side pollen filter. You'll have to remove that half of the cowl and then the screws holding down the DME cover. It's pretty easy to do -- only takes 5-10 minutes max. If you need step-by-step directions on how to get into the DME box, check out the JB4 installation PDF for the 535i on the Burger Tuning site. I believe the wiper relay is the only tan one in the box.

I was looking under the driver's side. I looked at the site you referenced...good stuff in the PDF...just what I needed. Thanks!

Allen, Did the relay change fix the problem?

I had the same problem as you, with the wipers not coming to a rest properly. The tried changing the wiper motors and some module, though it wasn't until I showed them a post from this site or another BMW site until they decided to change the relay. It solved the problem! Unfortunately, I do not know where the relay is located, but the p/n you indicated is the same as what is in my service write-up. Good luck!

The only reference I could find to this p/n and a diagram is this...

It seems that accessing the relay requires removing a bunch of stuff...basically a PITA. It's my wife's car ('10 528i) that has the problem, and it doesn't seem to bother her, so I have just let it go. If MY car ('08 535i) starts to have the problem...I'll change the relay...or do whatever it takes to fix it.

So I finally got around to changing the relay...and it fixed the problem. Wipers now return to the normal parked position. BTW...the diagram just above showing the location of the relay panel under the hood...is incorrect. The relay panel is located under the cabin filter housing on the passenger side

so, I know this is an old thread but figured I would post to help someone. my wife's 2010 528i had the same issue. the relay is tan and located under the passenger side filter box. removing it is much simpler than what has been posted (perhaps because its a '10) the cabin filter box has one hex screw and 2 bolts that need just a click to open. then there are just 5 bolts to remove the actual panel cover that covers all the relays etc. the most difficult thing for me was putting back the rubber stripping LOL altogether less than 15 minutes. saved $$$'s
