  • While the headlights are now sorted, I moved on to the window lifter switches and the back lights of the center console switches. The interior lights thread on the forum gave me inspiration to sort these out. Some of the window lifters did not work at all and all of the back lights were very dim. I decided to purchase new Meyle window lifter switches instead of replacing the leds in the old ones. Here is a comparison photo old vs new

    Back lights of the old window switch was not very good either

    So I replaced the lights. It was light outside when I took the photo so the difference is not so obvious

    Here they are all pictured in the dark. Window switch is still a bit dim compared to the mirror switches, even if I used a little bit more powerful bulbs than oe. But it will have to do for now.

    I also changed all the back lights of the switches in the center console. They are all evenly bright now but it looks a little like the rear window heater is on even though it is not. I will have to work that out in the future to make it flawless. Other than that, I'm pretty happy with the outcome. Again this picture is taken when it is bright outside. Finnish summer is kind of bright even at nightime.

    I took much more pictures during the process of changing the led's in these switches and my plan was to make a good write up on this, but as I never got into doing so, I figured I'd post a few pictures and couple of words instead

        I also had a increasing noise coming from the alternator, so I figured it was time to change the bearings. Luckily they are readily available. The removal of the alternator was a pretty straightforward job. After taking all the mounting bolts out and loosening the belt, one ac hose had to be loosened to get the alternator out under the car.

        Alternator on a bench. The shaft has place for a xzn10 socket to counterhold the shaft while undoing the nut. Luckily mine was not too tight.

        After loosening the nut the pulley just pulls out. Next was the removal of the rear plastic cover. Three small screws and a plastic clips on the side.

        Under the cover reveals the diode bridge. Three screws there as well


        20200118_124738.jpg


        After that you have to remove the stator leads from the diode bridge. I was a little afraid to do this because I wasn't sure if I can get the leads back on properly. There is a copper "double hook" where the lead are crimped. I took a small screwdriver and gently opened the connectors. Fortunately nothing broke and I was able to get the leads back on later. After the screws and leads are loosened, the diode bridge just pulls out.

        After that the casing bolts were removed


        20200118_125029.jpg


        I used a pin punch to gently tap the casing to loose the two halves



        20200118_125327.jpg




        The inner slip ring was worn. I suspected this and had already ordered new one



        20200118_125916.jpg

        The rear bearing just pulls out. (Yes I know its a sucky puller ​)


        20200118_130631.jpg


        Then it was time to release rotor from the front casing. I used a puller as per the pic


        20200118_140515.jpg


        And out. After this I just used a socket and a hammer to tap out the front bearing. Before that I took out the bearing retaining plate that holds the bearing in (sorry no pic)


        20200118_140818.jpg


        The casing got soda blasted. It doesn't take away the deepest oxidation marks but I can say it's cleaner than before!

        20200118_164705.jpg

        20200118_164718.jpg



        Then I took out the old slip ring. Just unsolder the rotor leads and brake the plastic around the shaft. When fitting new one be sure to align it correctly. The slip has a small snub that has a matching pocket in the rotor. After the slip rings were in I installed the bearing just by using proper sized deep socket and a hammer.

        Do you first desolder the stator leads from diod bridge or do you just open them with a screw driver ?

          I think that there is no solder used on the stator to diode bridge connection. I just carefully levered the connectors open with a screwdriver.

          • Now that the switches back lights are sorted, I fitted some footwell lights. I got the inspiration again from Audi Coupe OEM+ Interior Lighting Guide that can be found here.

            I found these interior lights from Tradition and they were 3 euros a piece, so I bought 6 of them

            20220507_134721.jpg

            Pretty soon it was obvious that I these are not meant to fitted by pushing into a square hole, so I had to take them apart and modify them.

            20220507_140826.jpg


            A little use of the dremel did the modifications needed. All the unnecessary plastic was cut off and I made the holding tabs a little wedge shaped so that they can be snapped into place

            • After modifying the lights to suit, it was just a matter of cutting holes for them. This is the passenger side trim with the hole marked out



              20220509_101512.jpg

              Dremel is a handy tool to have for jobs like these. This is a trial fit just to make sure everything fits before reassembling the light

              Same thing was done for the drivers side

              The wiring was done together with a window lifter loom repair, but more about that later.

              • Very nice -I think they are Coupe boot lamps.

                  Thanks! I checked the Tradition page and they seem to be fitted into Coupe.

                  • The wiring for the footwell lights were done together with the window lifter/sunroof loom repair. I had a failure in the old sunroof motor's microswitch so I had ordered a working condition used motor. It was a little surprise to find the new motor not working and the first thought was that the new motor was faulty too. After a little bit of investigating it was clear that the motor was not getting any voltage. So it was time to dig out the current flow diagrams and start looking for possible damages to the wiring loom. It did not take me too long to find this behind the rubber boot between the drivers door and A-pillar.


                    20220520_160201.jpg

                    Nearly every wire had a crack at the insulation and a couple of wires were completely cut. So it was time to send an order to vehicle wiring products for correct colored wires and start the disassembly. I really got into the work and did not remember to get good photos, but here are some. The jack is there to help me unbolt the door by myself Believe it or not, I actually got the wiring to look decent even if it isn't too obvious from the pics.

                    I used this type of crimp connectors to splice into the existing loom and just put an adhesive lined heat shrink tubing on top of it

                    20220603_115211.jpg

                    I did not get a final photo of the finished wiring. But here's a few pics of the footwell lights now working. It was still kind of a sunny evening so they are not too bright but I feel they look good

                        Thanks mate, the splice connectors are actually from a local Finnish company called Finjector

                            • I happened to find a forum discussion regarding fitting new wiper arms and aero wipers. So I had to get them too.


                              1.jpg

                              The passenger side wiper is a little too long, to I had to shorten it. There is plastic end cap on the wiper and I wanted to be able to use it on the shortened blade. It required a bit of modification to fit the cap, but it looks neat now.

                              2.jpg

                              3.jpg


                              The wiper linkage was rebuilt and well greased. Error 404's how to had good instructions for this. Not too much grease on the spindles.

                              4.jpg


                              After cleaning it was obvious that the plating on the spindles has somewhat worn off.

                              5.jpg


                              I also wanted to put grease in the ball joints. I used a spanner to pop the ball out of the socket, fortunately they were not too tight.



                              6.jpg


                              My wiper motors gear did not have the plastic end cap that could be removed. So I very wisely thought I could separate the motor from the gear and get a little grease put in that way. What I did not think, was that when opening the motor all the carbon brushes and their springs would come off I was able to put the motor back together, but it was all unnecessary work.


                              7.jpg


                              Here is the end result, I think they look good and the aero blades are much better imo.


                              8.jpg


                              I also purchased these. They are led puddle lights to be fitted under the front doors They are not installed yet, but i will post photos when I fit them.
