Sony/Blaupunkt 10 CD Changer

Sony/Blaupunkt 10 CD Changer

The Audi 10 CD changer was manufactured by Blaupunkt under license from Sony, which would make it a Blau/Sony with Audi markings. I figured that a Sony was going to be easier to find, so that’s what I ended up with. The unit in my car is a Sony CDX-A30, which fits the stock mounting brackets perfectly.

AFAIK, as long as it has the single 13 pin DIN cable hookup (the blue cable shown in the picture) it should interface properly with the stock radio and transceiver (the transceiver is what makes the changer visible to the radio).

Part numbers:
Transceiver: 4A0 035 239 (Blaupunkt 7 607 765 082)
Bracket: 4A5 035 113 (sedan)
Cover: 4A0 863 716 (sedan)

FWIW, a quick search on “Sony CDX-A30” at turned up the following information – Caveat emptor, no warranty expressed or implied, etc. 😉

UrS4 / UrS6 Airbag Warning Light Fix

UrS4 / UrS6 Airbag Warning Light Fix

This procedure addresses the false two-minute airbag warning light that occurs upon vehicle startup for some vehicles.


vehicle maintenance records
thin blade screwdriver
4 mm allen wrench


If you have a ’92, verify that the KF14 recall was done on your car. If so, you have an AIRBAG II system. The dealer can tell by your S/N if the recall was done. If not, then let the dealer upgrade your airbag and fix the light for free! Pry the trim piece off that surrounds your HVAC Central Control. BE CAREFUL to go slowly. See the procedure here: HVAC Head Unit Trim Removal. Unscrew the two 4 mm Allen Head screws that hold on the trim piece spring clips. Lift out the central control unit and swing it out so it rest on the passenger seat. Use a flashlight to help you see the AIRBAG triggering unit (labeled as such). Note the connector on the left side of the triggering unit and note the grey foam that is just above the connector. Inside the foam are the two 2-pin connectors that hook up to the VAG-COM. These connectors are identical to the ones under the left side of the hood, used to access fault codes. Push back the foam to connect the VAG-COM. Turn vehicle ignition to ON. Follow the VAG-COM menu to view and clear your fault codes: Menu 1 – Click Select Menu 2 – Click 15 – Airbags

Menu 3 – Click Fault Codes – 02

Menu 4 – Click Clear Codes – 05

Install is reverse of uninstall. You’re finished!

Europrice Short Shift Kit Installation

Europrice Short Shift Kit Installation

While this write-up is specific to the Europrice SSK, it should be applicable to any SSK that replaces the whole shifter assembly, and can be used to R&R the stock shifter assembly if replacing worn parts. Read though the whole procedure first, as there are some reference marks that will be useful during reassembly. Make sure your shifter is in neutral.

Step 1: Remove rear console. Thisis described in a separate write-up.
Step 2: Remove front console. This is described in a separate write-up.
Step 3: Remove crossmember. Crossmember isheld on with ten (10) 13mm nuts (Figure 1).

Figure 1 and 2

Step 4: Separate exhaust system from downpipe. If you have a Stromung, you will need to remove the center section only. If you have a stock system, you may get away with only having to remove the cats, but will probably have to slide the rest of the system rearward for clearance to work.
Step 5: Remove two (2) 13mm retaining bolts from torque rod and shift rod connections (Figure 2). Along extension on a 3/8 ratchet worked for me. You shouldn’t need a universal joint. Mark the torque and shift rods for insertion depth into the forward rods for reference before removal.
Step 6: Remove the four (4) 10mm bolts holding the top portion of the stop bracket, and remove the bracket (Figure 3). Take notice of bolt positions asthese hold the rear locator that accepts the pin on the rear of the shift assembly.

Figure 3 and 4

Step 7: Remove the insulation blanket from around the shifter assembly (Figure 4).
Step 8: Remove the four (4) 10mm nuts holding the lower portion of the stop bracket, and remove the bracket (Figure 5).

Figure 5 and 6

Step 9: Remove the whole shifter assembly with weather boot by lifting up and out towards the rear. You may have to wiggle it slightly to get everythingmoving (Figure 6). Don’t be concerned with the splines on the torque and shifter rods. The forward rods attached to the transmission are not splined on the inside at the connection points.
Step 10: Clean and transfer the weather boot to your SSK. Measure and transfer your insertion depth reference marks made in Step 5 to the SSK rods.

Weighting of SSK shift rod
If you do not plan to weight your shift rod, skip this section and go to the Reassembly Tips section.
Step 11: Lock your SSK in a vise as shown (Figure 7).
Step12: I went to Pep Boys to ask if I could grab some used wheelweights out of the junk bucket next to the tire changer. While I was rummaging through to find the cleanest ones I could, one of the mechanics came up and gave me a box of brand new ones. Score! Anyway, you need to obtain some lead wheel weights. I used approximately 14oz of weights to fill up the hollow in the shift rod.

Figure 7 and 8

Step 13: Remove the steel clips from the wheel weights. Heat the weights in some type of container. I used a plumber’s ladle (Figure 8) I had which was used for running lead plumbing joints way back when. You can still get these fromplumbing supply housesfor around $35 if you are so inclined. I used an acetylene “B” tank for my heat source.
Step 14: Heat the weights until they liquefy, and pour into the shift rod (Figure 9). You should probably wear a mask when heating the lead asI’m sure lead fumes are not good to inhale.

Figure 9

Re-assembly Tips
Step 15: I used anti-seize on the torque and shift rod ends to facilitate disassembly again in the future. Reinstall the SSK through the opening inthe floor. Line up the rod connections from underneath. There are no splines onthe inside of the forward rods, so don’t worry about alignment. Get the retaining bolts started to keep everything from coming apart.
Step 16: Reinstall the lower portion of the stop bracket, and tighten. Make sure you slip the rubber support over the pin on the rear of the shifter assembly. Reinstall the top portion of the stop bracket. Before tightening the bracket in place, make sure your transmission is still in neutral, and align your side-to-side shifter assembly position (for neutral). Tighten down the top portion of the stop bracket.
Step 17: Set the front-to-back shifter assembly position (for neutral) by adjusting to the marks on the torque and shifter rods made in Step 5. Tighten the torque and shift rod retaining bolts. Reinstall the insulation blanket around the shifter assembly.
Step 18: Reinstall your front and rear consoles and you’re done.

AAN Compression Test – Acceptable Specifications

AAN Compression Test – Acceptable Specifications

The acceptable “Compression Pressures” are:

Specified Value: 9.0 to 13.0 Bar (131 to 189 psi) (ED: 1 BAR = about 14.5 psig)
Wear Limit: 7.0 Bar (102 psi)
Maximum permissible pressure difference between individual cylinders: 3.0 Bar (44 psi)

I do not like to see more then 10%– but that is me and does not mean that your engine might have unacceptable leakage. Perform a leak down test and see if it can be determined where the leak is coming from. If you hear it out of the CC breather or oil fill then you may have ring wear. With the hard cylinder coating and the ring design these days, I have found that cylinder leakage is not as common.

More often you hear it out of the exhaust or intake. Have a friend go back to the exhaust tip if you run it again to take a listen.

If it is the valve seating (I assume you did this at TDC) you may simply have carbon build up and a good tank of BG44 may improve your readings.

1994 UrS4 Side Mirror Glass Replacement

Sooner or later most UrS4/UrS6 owners find that their rear view mirrors have started to delaminate.  Why put up with decreased vision and an ugly mirror when a replacement heated mirror glass can be had for about $85 from your Audi dealer?

Removing and replacing this mirror is far from difficult but I figured it still wouldn’t hurt to put up a quick video FAQ on the subject.


Additional notes: On the later cars the outside mirrors were often a two piece design with a black plastic piece on the bottom that is held in with several screws. Many people find that removing this trim piece allows for easier access to the mounting tabs that hold the mirror glass in place. Naturally, this makes it less likely that you will break these tabs during the removal process. In my case, using the two tire levers and a small flat screwdriver made for quick removal without any damage but you may want to err on the side of caution if you tend to be heavy handed. 🙂

Getting Your Shine On!

Getting Your Shine On!

Spoiler has been buffed.  Contrast?  Oh yeah!

Spoiler has been buffed. Contrast? Oh yeah!

Let’s face it, if you own and drive an original S4 or S6 you’ve got an old car. These cars are special and in many cases they have been maintained to high standards thanks to enthusiastic owners. Unfortunately, that isn’t always the case so some cars end up looking, well, a bit tired.

I’ve known the owner of this black S6 online for quite sometime but only recently had the opportunity to connect with him in person at the Glacier Lakes Quattro Club Spring Ice Out event. The owner (Tom) drives a nicely tuned black UrS6 that at the time of this posting is going on 260,000+ miles! Mechanically the car it doing well but the paint has certainly seen better days. At the Ice Out event I told Tom that we needed to get together and work on buffing his car back to life. That day finally came on Saturday, August 19th, 2012.

I’ll be honest, I wasn’t sure I could save Tom’s finish using the limited buffing pads and compound that I had on hand. Since the oxidation on Tom’s car was pretty severe I would have liked to start with a more aggressive pad and compound but we sort of planned our get together at the last minute so I decided to run with what I had on hand… my Porter Cable buffer, two orange foam pads and 3M Finesse It II polishing compound. This combo isn’t terribly aggressive and is what I normally use on my own UrS4 each spring. I didn’t know if it would be enough to save Tom’s UrS6.

As with any detailing effort start with a very good car wash… and by that I mean do it by hand with soap. We used Turtle Wax T-79 Zip Wax Liquid Car Wash
but you can substitute your favorite here. Once the car is washed dry it VERY well and let it sit until all the water is done running out of the body seams (it helps to blow it out with compressed air too if available).

Next I will generally go over the car with the Mothers California Gold Clay Bar System to remove any remaining surface contaminates. This step helps your finished surface feel extra smooth to the touch.

Now the car is ready for buffing. For this step I’m a big fan of the Porter Cable buffers. In my own garage I use a slightly older version of this Porter Cable 5.5 x 7/8 Inch CCS Foam Pad Kit kit. On most cars I use an orange foam pad in conjunction with 3M Finesse-It II Glaze to achieve a very nice shine without being too aggressive. This is also what we used on Tom’s car even though we could have started out with a more aggressive pad and polish and done multiple stage buffing to achieve best results. Since I had only an orange pad and Finesse It II and one day to get it done we opted for the single pass attempt.

The car buffed back to life with amazing results. Granted, there are still some imperfections in the paint but for a simple single stage buffing the car looks night and day different. Had I done things the long way I think I could have brought the car back to 98% or so but it would literally take me 3 days or so to give it that sort of attention.

To finish things off, we gave the entire car a coat of Turtle Wax F21 Car Polish. I know this may seem somewhat crazy as F21 is an inexpensive non-wax based polish but I have honestly used dozens of products over the years on my own and other people’s cars and when it comes down to a product that gives me a nice even shine, ease of application and removal and a long lasting shield for cars that sit outside a lot this F21 is a great solution. It is virtually the only product I’ve used that doesn’t make me hate life while trying to get a nice deep and even shine on my Tornado Red UrS4. Naturally, feel free to use whatever you like the best.

To finish things off I use a little Mother’s Quick Detail spray (included in the clay bar kit mentioned above) and a white foam finishing pad to quickly go over the entire car for a nice uniform shine.
