Nizmo's S6 V10 Thread

[Nizmo]

2008 S6 5.2 V10 128,00 Miles.

Started some maintenance chasing some oil leaks which are pretty common on this engine. Previous to this work, the Oil Filter Housing Seals had been done. (Part#079103121BE ; N90959701) These engine blocks are almost identical to that of the R8 and Hurrican, therefore reminders of this pedigree while working on this beast is mandatory. 2 Turbos and a dry sump oil system are nearly all that separate us from the legendary C6 RS6 engine. Lots of components coming off and expect to replace quite a few one time use bolts and plastic clips. I will try to reference OEM parts wherever possible.

The Plan:
-Front Main Seal (079103051F) x1
-Oil Cooler Seals (079103121AD) x2
-Oil Control Valve Seals (WHT002789) x4
-Harmonic Balancer Bolts (N91005903) x8
-Cleaning

Added Parts
-Ribbed Belt (07L903137E)
-Belt Idler (079903341F)
-Belt Tensioner (07L903133H)
-Small Terminal (N10335807) x 20
-Repair Wire (000979131E) x 20
-Runner Position Sensor Connectors (3D0973703) x2
-Throttle Body Connectors (1J0973713) x 2
-Alternator OEM
-Alternator In/Out Seals (WHT 001 225) x2
-Thermostat
-Lower Radiator hose

Front Main Seal



What a pain this was, Ill be sure to get the Audi special tool for this one next time, Ill be on the lookout for the tools (T40019 ; T40048). I wound up cutting most of the seal in half with a Xacto knife. FYI My seal puller I couldn't use until I cut the seal halfway because you cannot put pressure or mark the aluminum or crank surface by prying with a conventional puller.

I wound up rewiring the throttle body connectors to the harness, was getting some EPC and traction control lights (safe mode) intermittently, I replaced the suspect throttle body with used OEM and ultimately rewiring was the fix. Also I wound up rewiring the Runner Control Sensors and 1 of the Knock Sensors as some damaged insulation was found and cracking of the wiring. Also, the codes Im getting show runners stuck closed, this is on my 3 year old "Revision M" manifold from 2016. I may need to buy another or see what Audi will do for warranty. Took some time to add wiring loom to some missing wiring around the Intake Manifold that has deteriorated off, C6 S6 owners know what Im talking about.









I will update the thread as progress continues. Long live the C6 S6!

Small Update:

I have gotten the car flashed with JHM 91 Tune and SAI delete option. It has removed the cold start and therefore the runner control flaps. This has allowed the car to pass state inspection!

The car will get a carbon clean and new fuel filter. I haven't decided if I am going to replace all the injectors or not while doing the carbon clean.

The car has also had the front bumper repainted and carbon OEM grills installed as well. The plastic vent on the right side had a cover blocking all airflow. It was easily removed.

First time no errors, no CEL, no lights on dash. JHM Tune couldnt be happier.

Brand new OEM headlights!

Hi Nizmo, question about the carbon grilles below the led driving lights on your S6...Nice job with it by the way. Where did you get carbon grilles or are the just covered...Would love a set for my S6. Thanks for your help

That is going to be your water pump housing, have a look on FCP Euro
The plastic that you see is the back of water pump
