The pains of finding wiper blades for the i3.

The i3 uses a beam style wiper blade, with the OE part being manufactured by Bosch in Belgium. It appears to be based off a European market wiper blade, the AP750U. This would be a 29.5 inch blade here in the U.S.A. Many auto parts stores stock Bosch ICON wipers, which are very high quality, and quite comparable to the OE wipers. Unfortunately, this is where the fun begins. Bosch ICON wipers are available in up to 28 inch sizes. Most aftermarket parts catalogs list the i3 wipers as being 28-inch Driver, 21-inch Passenger (This is U.S.A. LHD spec). The passenger side wiper is indeed 21 inch on the OE part, but as I mentioned earlier, the stock driver wiper blade is about 29.5 inches. There are other types of beam style wipers that can be fitted (please, don't use the non beam style wipers with your i3), and I also tested the Trico Ultra which fits and wipes well too.

The problem is, the 28 inch wipers are just barely NOT long enough to wipe in front of the forward facing camera. The stock 750mm wipers do clear that area. If your i3 does not have the Technology Package (Adaptive Cruise Control), then don't worry about that, as the 28-inch wipers clear a plenty big enough sight area, and also cover the auto wiper sensor.

TL;DR, if your i3 doesn't have the technology package, you shouldn't have any troubles with the commonly available 28 inch wipers. If it does have the technology package, you'll need to get the OEM wipers that are long enough (Or, if you live somewhere where you can get Bosch AP750U wipers easy enough), else you may get a "camera obstructed" check control message, and your cruise control features will stop working.

Yes, that looks correct.

Just a nit, but I think the auto-wipe sensing is done with a microphone listening for raindrops hitting the windshield. On the other hand, my i3 without the tech package does have a single optical sensor in front of the mirror. It could be for the wipers, and certainly is not for auto-dimming the headlights (not a function on the car), but could be needed for the auto-dimming of the mirror so as to not dim during the day.

Regarding the windshield rain sensor... it's optical, based on the IR light reflective properties of the windshield - which change when water is on the exterior surface of the glass.

Just got a wrong set of wiper blades for my Tera World with the Technology Package... they shipped the Bosch A103S with 28" and 21". I ordered the BMW part number (without the hyphens) - the 61612410957... but it's not right. Now they want me to take a picture of my factory wiper blades next to what they sent me.

I'm beginning to understand why BMW wanted to charge me $120 to replace them when I had my car in for warranty service... but it still doesn't make it right.

We'll see how good this "xxEuropean Auto Parts" dealer is.... hopefully I'll report back with good news, and maybe I'll find them worthy of my repeat business.

Well, my new wiper blades are good!

It's odd that the Bosch package calls them 700mm & 530mm, but the actual rubber insert was indeed a full 750mm (29.5"). Maybe Bosch decided their original "Aerotwin A 103 S" wasn't what was needed, and just lengthened the drivers' side blade without making new packaging.

Thanks RMEuropean !

Search for "Bosch Aerotwin A103S" but this dealer sells them under the BMW part number without hyphens: search for 61612410957 https://www.rmeuropean.com/Make/PartNum ... 1612410957

Costco sells bosch wiper blades and they fit fine. I believe installed 28 inch on driver and 19 on passenger.

The 28 inch wiper blade after a year or so do not slide very well because its just too long!

Going to try 26inch wiper blade.

ps- dont trust BMW ACC on a perfect day after a bug triggered collision warning! And another day, just rain.

Not hard to find. It's the same wiper blade that fits the MINI Cooper rear hatch 2004 - 2013
