  • My wannabe S6 Plus project

    Decided to share my story of my TDI quattro that I have been improving over the last 6 years already. Bought it as my first car. Since I have had to do a lot of driving these years(altogether over 100k km in 6 years) I had to get something economical but it had to be a quattro. C4 S6 would have been nicer but not a student car so much. So that's what I started out with:

    The exterior of the car was totally stock A6 C4, technically it had quite a few flaws and problems that I started to figure out, although the engine has been running strong and the body is good also, not much rust.




    The interior was not very nice, steering wheel leather worn and also the driver's seat.





    Over the years I always thought I am not gonna spend a fortune on a car project - but for now I have spent quite a lot of time and money retrofitting all the goodies to this car.

    The car previously had -
    1AH = electronic differential lock (EDL)
    1BE = sports suspension/shock absorption
    1G3 = alloy spare wheel with original equipment tires
    2PV = leather trimmed sports steering wheel
    3AF = outer right rear view mirror: convex, powered, heated
    3BS = outer left rear view mirror: non-spherical, powered, heated
    3FQ = electric sliding/pop-up sun roof with automatic pre-selection
    4UE = airbag f. driver a. front seat passenger
    8AE = radio "delta"
    8RQ = speakers (active) with BOSE sound
    C1L = cast alloy wheels 7J x 16 five-arm style, offset 45
    M49 = 5-cyl. turbo diesel engine 2.5 L/103 kW with MVEG 2 base engine is T4E
    Q1D = sports front seats

    So it did not have very good equipment, it even did not have the automatic AC but I wanted it and some other features.

    And for now I have made my own equipment list what I have added to the car.
    • OEM automatic climate control with all original wiring and piping
    • 4x electric windows(with OEM wiring so the windows will be operated by central locking also)
    • Front fog light retrofit
    • Headlight washers with custom wiring(original relay) but controlled by a button on the wiper stalk(custom wiper stalk from A4 B5 Avant matched with C4 Avant one)
    • OEM flip key with Aerial central locking pump that communicates 433.92 MHz
    • OEM xenon lights with good Hella ballasts not some random aftermarket ones
    • S6 Plus electric sports leather seats with memory for drivers seat and for the mirrors
    • A8 D2 facelift big mirrors with memory function and auto dipping passenger side mirror and also folding
    • Chiptuning for extra power and to kill the dual mass flywheel
    • Single mass flywheel with 4.2 V8 pressure plate and 2.5 TDI AAT clutch disk
    • S6 Plus rear hatch with the 3rd brake light spoiler
    • S6 rear hatch light
    • S6 Plus blue instruments(with TDI spiral light for glow plugs)
    • S6 Plus shining black roof rails
    • S6 Plus 17x8 wheels
    • S6 Plus steering wheel
    • S6 Plus gear knob(brand new)
    • S6 brakes and struts with complete rehaul
    • S6 front bumper with fenders
    • S6 rear brakes with complete rehaul
    • S6 steering damper
    • Servotronic wiring and steering rack
    • Complete respray
    • urS4 "quattro" inscription rear glass
    • S6 strutbar
    • Glass sunroof instead of steel one
    • Dark headlining with all original S6 Plus plastic parts(not painted)
    • OBD II plug in center console like US sold C4-s
    • C5 facelift chrome exhaust tips

    And now some pictures of retrofitting and etc.
    They are somewhat organized and some of them have some description also.

    New steering wheel leather


    Rear diff seals replacement








    Cruise control retrofit


    S6 rear light


    4.2 V8 clutch pressure plate with 2.5 TDI AAT clutch disk


    Blue soft cloth interior that I had in the car for some time



    S6 Plus rear hatch spoiler



    Instruments workshop


    S6 Plus blue instruments


    S6 Plus with glow plugs


    New S6 Plus gear knob




    Original electric seat supports welded


    Coated to protect from corrosion


    Seat supports painted


    Drivers seat fitted


    S6 Plus door cards with carbon trim and black door levers


    Hella xenon ballasts just for more OEM


    Ballast fitted


    Xenon lights fitted and working


    New flipkey




    Adding 2 pins to central locking pump wiring




    Bench testing my climate control system








    Retrofitting the piping



    6.6L windscreen washer fluid reservoir with two pumps instead of 4.4L


    Can I put it back together??









    It works!


    Seat heater bulbs look dead in the picture, IRL they are good.


    OBD II plug in center console like US late C4-s(despite the cover)





    I cover it with the original piece of carpeting when not in use.


    Some new tires(Nokian Line 225/45/17 91V) for the Plus wheels


    Under the car


    Gearbox oil change


    FEBI oil that is applicapable to GL-4 gearboxes - I do not recommend, crunchy gear changes guaranteed changed it to OE in few thousand kilometers.


    That's more like it.


    Black anodized trims




    Old brakes and struts


    HP2 brakes getting sandblasted and powdercoated




    I don't like aftermarket ABS sensors so I cut a rusted A6 struts to get some original sensors




    Some new parts


    S6 struts sandblasted and powdercoated, old A6 one on the right.










    Rear brake splash guards S6












    Doing a custom wiring for memory mirrors to integrate folding function to the wiring. There are some cars with memory and folding mirrors but I have not seen in person.


    Labelling the wires and soldering


    Mirror folding relay


    Retrofitted the Servotronic steering rack with S6 steering damper


    Here is the Servotronic relay and also the "Komfortblinker" relay can be seen here.


    A quick "zahnriemenwechsel".


    It has been a driving project also, not always standing in the garage.


    Getting ready her for a paint job.






    The quattro glass I will fit to the S6 Plus rear hatch.


    Old headlining coming off












    Overhauled drivers door hinge








    After painting








    Difference between door seals seen below - S6 Plus on the left and standard on the right.


    Gluing the new headlining, old armrest works great.


    That's a bad picture. Too many pictures to notice this I hope.


    All parts fitted to the headlining. I like dark headlining.


    Glass sunroof and a new windshield.


    That looks reasonable thing to do.




    That's C5 TDI Facelift tips.




    That's how she looks at the moment. Sorry for the super long post.
    Hope you guys find it interesting or worth looking because it is still a TDI.

              Astounding.

              As good as mdz's thread, and that's saying something.

              Love everything you've done including the window trim changes.

              The only things I would have done differently is 255/40/17 tyres, black brake calipers and Bilstein shocks with H&R 29800 springs with Albert's front arb mounts to increase castor.

              While stating the above as things I'd pick out, there are many many more items that you've done that are brilliant and the end result is stunning given what you've had to do.

              Thanks for sharing. Made my day, puts the work necessary on my UrS6 into perspective.

              Enjoy.

                  How did you remove the old black plastic sill trims and what did you use to put them back?

                  Thanks.
