Hi, I’m new on here. I seem to kinda like Audis since I’ve owned 2 A6s (C5 and C7) and recently got an S6.
The car has around 200k miles on the clock, but the engine “only” has 100k.
It had several things wrong in the beginning, including a broken exhaust, vibration while driving, CEL, EPC warning, a loose control arm and some torn bushings etc etc. Probably not the most intelligent buy, but I got it pretty cheap.
Fastest car I’ve ever driven even with all the problems, and drove quite nice actually. I’m not very handy and the last time I’ve worked on a car was like 15 years ago, so I knew I would mostly have to have the work done by someone else.
Here’s what was done:
-
Wash !
-
Oil & filter change. Attempted this myself, but broke a coolant line in the process. Panicked and had it towed to a garage for repair in order not to break more stuff. Only later realized I could’ve pushed it to a parking space or even driven it home in that state, and the hose I broke was the tiny plastic one which I’ve now learned always breaks eventually.
-
New tires (less vibration)
-
Con artist workshop diagnosed all kinds of problems with it and changed a bunch of stuff that wasn’t really needed, and charged too much for it too: front brake rotors, some support arms, drive shaft, fuel filter, cabin air filter.
-
Spark plugs (noticeable increase in power)
-
Transmission oil change and flush (no problems encountered)
-
Fixed the steering wheel electric adjustment myself by using OBDEleven and doing its basic settings adaption. Now it moves in all directions like it’s supposed to.
-
Had the front window and headlight tint removed.
-
Interior clean and headlight polish + protection film
-
Fixed the exhaust. This was cheap. The welding looked pretty crappy and unsure about this job, but at least it doesn’t leak.
-
Carbon clean, injector inspection which resulted in all 10 injectors having to be replaced, new K&N filters (attempted to clean the old ones but used a hard brush before I learned you’re not supposed to do that so I bought new ones since the old ones were in horrible shape anyway) - noticeable increase in power again !
-
Changed a bunch more control arms etc, this time in a much cheaper and better workshop - by now almost everything in the chassis is new (not sure if chassis is the correct word, I mean the control arms etc)
By now I had found two nice workshops that are humanly priced and whom I can trust.
-
New wheels (finally cured the vibration while driving ! turns out the old wheels were not round anymore and had cracks in them)
-
Rust removal and new paint job (found someone to do it dirt cheap and they did a good job as well as far as I can tell). They also changed the front mask to a honeycomb one while at it, and fixed my parking radar by just replacing a 25$ sensor that I had bought myself (the con artist garage I mentioned previously wanted 700$ for the job - thankfully I refused).
-
JHM transmission & ECU tune (the transmission tune is great, ECU tune I’m not sure I can tell improvement over the previous APR tune)
-
Throttle body connector pins were tightened (the car had developed a problem where it would go to limp mode after almost every cold start). This fixed the issue, and later I had the connectors replaced altogether just in case.
This was the third workshop that seemed to really know what they were doing with electrics.
-
Nunoo Android multimedia player with touchscreen from AliExpress (actually great)
-
APR Coils and fixing a broken bolt in cat 4 + JHM Intake Heater Bypass. Not sure they actually fixed the right bolt since I haven’t looked under the car. The coils seemed to actually decrease power… I will change them back to OEM.
-
Custom 3" to 2.5" catback exhaust (noticeable bump in power!)
-
Custom S6 mats from https://www.autostyle.co.uk. The front mats are really nice, but the rear mats don’t seem to line up perfectly. Would still recommend as the quality is excellent.
What I have coming up:
-
Ceramic coating and renewing the awful chrome delete tapes and a bunch of other minor detailing
-
Fixing the threads in the intake manifold (currenty they’re busted and the manifold is epoxied in place)
-
Installing a set of new flaps in the intake from https://excase3d.ru/catalog/kollektor-vpusknoj-audi-s8-vkladyshi-vihrevyh-zaslonok/ Currently the intake is gutted. There were all kinds of problems getting these into Finland since mail doesn’t currently run between Russia and Finland. I had to have these mailed to a friend in another country, then the idiot got thrown into prison right when the package was already being shipped, and they had to send me a new set to another friend, who thankfully came through and I now have the flaps ready to be installed.
-
JHM Intake spacers
-
JHM Lightweight crank pulley
-
JHM Lightweight brake rotors (I already have the rear ones on order
What I plan on:
- Lighter wheels from Japan Racing (they weigh 2.5kg or 5.5lbs less than my current ones per wheel).
What I dream of:
-
Custom exhaust headers (this is gonna be super expensive to have done if I end up doing it – can’t gut the cats due to emissions)
-
Forced induction. I thought about VPS Verstärkt’s supercharger system, but read on here that it’s shit so I scrapped that idea. Turbocharging would be super difficult and expensive. Maybe an electric turbo at some point such as TorqAmp, which is meant to actually work unlike most of them…
Oh, the car is truly magnificient already by the way ! Everything works, it drives well etc. Really happy with it 
Mikä meininki?
