Ti Kan: Audi - My S4 2.7 biturbo quattro

Gallery 2

These images were taken after I upgraded the headlights to European specification Xenon HIDs, and installed new wheels and tires. The new headlights have significantly better beam pattern than the stock USA specification Xenons, and have city lights and clear corner lenses (no orange filter). The car now rides on 2004 Audi S4 18x8J ET45 Avus-design wheels, shod with Continental SportContact2 235/40ZR18 97Y tires. To fit these, I had to add 5mm thick H&R hubcentric aluminum spacers to both front and rear with matching longer wheel bolts. Also new (not shown) are a set of "Eurolocks" anti-theft wheel locks.

November 2005: I Installed a new Audi/PhatNoise digital audio system in place of the factory CD changer in the trunk. See pictures below. I was able to rip over 400 CDs worth of music onto a single 20GB DMS cartridge. Instead of using the supplied PhatNoise Media Manager software for ripping, I used my own software xmcd on Linux (In Ogg Vorbis format which is supported by PhatNoise and sounds superior to MP3 at the similar bitrates). I also used the PhatVoice software to generate the voice prompts, which allows me to tailor the voice announcements for better pronunciation.

January 2006: The PhatNoise DMM catridge was upgraded to a 80GB unit.

July 2006: I upgraded the tail lights to use LED bulbs. These bulbs are slightly brighter than stock, will never burn out (rated over 100000 hours of operation), and have super-fast turn-on and turn-off times for instant attention. The following table shows the application:
 Stock bulbLED replacement bulbVendor
Turn signal/hazard light 1156 (21W) Luxeon 1156-RLX3 (red) Super Bright LEDs
Tail light/brake light 1157 (5W/21W) Luxeon 1157-RLX3 (red) Super Bright LEDs
Reverse light 1156 (21W) Luxeon TerraLUX V-Star1 TLE-12W (white) LuxeonStar

Each of these LED bulbs utilize a single LED rather than an array, and plug into the stock tail light sockets, with no cutting or housing modifications needed. The wide light angle of 130° means that the reflectors and lenses in the tail light housing are still utilized for the total light emission.

Additional load resistors must be installed to maintain the turn signal blink rate and keep the car's auto-check system from displaying a bulb-malfunction condition. I used 15Ω 15W resistors for the turn signal/hazard lights, and 25Ω 10W resistors for the other bulbs. These are the Arcol aluminum power resistors, HS15 and HS10 series from Mouser.com. The resistors are mounted on a heatsink for proper dissipation. With these resistors, everything functions perfectly and yet the total power consumption is still far less than with the stock bulbs.

April 2007 I upgraded the interior rear view mirror to one from an 2004 Audi S4. The original mirror was an electronic mirror with auto-dimming, but the new mirror also has a digital compass display in the upper right hand corner. There is a pushbutton switch that enables the auto-dimming and compass features to be (independently) turned on and off. The Audi part number of the new mirror is 8E0 857 511 A 01C. It required minor trimming of the mirror's plastic wiring cover to fit, but is otherwise plug-and-play.

August 2007 I replaced the front brake pads with EBC Redstuff pads, and installed new OEM front brake discs.

November 2007 I replaced the engine turbo diverter valves to the updated version, Audi part number 06A 145 710N (Bosch 0 280 142 114). See mike01s4's articles (part 1, part 2) about testing results of various diverter valves.

I also replaced the after-run coolant pump thermoswitch with one that is rated at a lower temperature (original was Audi part number 357 919 369F, rated at 112°C, the replacement is 021 919 369, rated at 93°C/88°C). This turns on the reverse coolant pump and auxiliary fan after engine shutoff for up to 10 minutes to reduce heat-soak, and should help extend the turbos' longevity. This AudiWorld tech article provides the full details.
