How to replace windshield washer pump

How to replace windshield washer pump


This is a job I have been putting off doing on my '99 Carrera Cab. As it turned out, it was pretty easy to do. Unfortunately I didn't take any pictures, so you will have to settle for the narrative: I was in a bit of a hurry, and I'm somewhat format impaired and don't know how to get the pictures small enough to be able to attach. Sorry for that, but here goes with the directions. Someone with really small hands might be able to do this without removing the reservoir - not me. Tools: Phillip #

I just did this, and the instructions weren't quite right for me.  I have a 1999 C4 Coupe with Xenon lights and washers so the reservoir is a bit different. Note that the headlight system and the windshield system have their own pump motors, and those pump motors are two different part numbers. They both draw from the same reservoir.

 

Step #4 is important. I didn't expect so much fluid, so I had to work in a puddle the rest of the afternoon. The filler neck is also surprisingly low, so you'll be draining for a while before you can get to Step #5.

 

Step #6 is the big difference, tho. The larger M288 reservoir extends forward past the center of the front wheel. There, it's held up by an M6 bolt, and by a plastic support arm that itself is held up by an M8 bolt. These two bolts must be removed, then the arm moved out of the way, to allow the reservoir to be removed.

 

The larger reservoir is difficult to remove because the hoses for the headlight system constrain the movement of the reservoir. I pulled forward, then rotated "out". I had to remove the headlight hose from the headlight pump before I could get the pump completely out.

 

These instructions were super helpful, but I did want to point out the differences in the M288 setup so that drivers with the headlight washers might get through the job with a surprise or two less 🙂
