Oh, not to mention, in Europe, gasoline prices are absurd. So a turbo always wins, when someone compares say, 3yr lease costs. Even if the turbo car costs a.leg and an arm more. The big N/A is a gas guzzler and makes for a poor gas economy, even in FSI. (Mine plows through 98RON E5% at around 12litres/100km or 19.6mpg.) and we think 4 litres/100km or less, or 58.8mpg+ is the good number…
Edit, mostly highway driving, it gets slightly, not awfully, worse in town.
Do you really manage 12l/100km?
Best I’ve got was 17,4l/100km RON98.
Mostly I get between 19 and 22 l/100km.
The car runs and performs just fine, has had 10 new injectors a year ago.
Does this mean I’m due a carbon clean?
@dzow when was the last time you had a carbon clean…
What maintenance did you do at the time of the injectors. What was the carbon situation like when you did the injectors. That will all tell you if you need to do anything.
This injector change was with the Previous owner.
I have a bill from a Bosch specialist where the car was because it was running rough. They then switched injector 8 and all the spark plugs after troubleshooting everything. A few days after this bill I have a second bill for the 9 other injectors (last owner had a company with a truck repair of its own therefore there are 2 bills).
The first bill isn’t totally clear since they ‘cleaned’ the engine but it doesn’t say what method.
That’s why I’m considering a walnut blasting but I wanted some advice first because they charge me 800€ here to do it and the only reason is the consumption that seems high.
Other then that no codes whatsoever.
Sorry, as forum newbie, I was not allowed to reply straight away. In my case consumption depends heavily on driving. I was hypermiling and actually got it momentarily under 11.4, but it went back up to around 12 after a few “spirited” passes. Around town it gets worse, even when trying to be decent.
My average for about 5000km is around 16,5L/100km, over half of it is highway driving (quite heavy on the gas pedal mostly)
Can aftermarket suspension options be discussed in more detail?
2008 Audi S6, second owner, 95,000
Took the chance and so far has payed off, alough I did notice there was some oil drops
I took the plastic cover off and it looks like it is starting from the front, any ideas
Oil leaks are a very real thing with the 5.2 if the maintenance isn’t up to date.
Generally the two major sources of oil are from the valve covers and then from the oil filter housing O rings. when the O rings leak the oil goes into the motor valley and then come out the drain holes in the front of the block
I can search later when I have time and help shown more documentation… Feel free to make a standalone thead on this and your introduction. There are many pictures and members who have all had this as a normal thing.
My belly pan looked like that. It was the figure 8 and sandwich flat gasket under the oil filter housing filling up the space under the IM full of oil. Dripping down the front
Spacers for the intake manifold. Man I know there are zero mods for our S6 c6 . So I started fabricating things. AL Spacers I got the idea from jhm.
There are tons of mods for the S6
There is a 2.75 exhaust
ECU tune
TCU tune
LW crank pulley
Intake spacers
LW rotors
I chose the v10 so I wouldnt have an endless list of mods to do to it. Get in and go
I have a question, wondering if any other C6 owners experience what I am.
Under hard acceleration near WOT my car will consistently lose power momentarily around 4500-5000rpm. I have wondered if the manifold is not functioning as it should?
Also, sporadically under the same throttle input the car will surge and accelerate for a brief moment(seemingly not matching how much throttle I am applying). Fuel pumps?
Any thoughts would be appreciated.
I would always start with are you getting any stored codes.
The pause in power in that range could be the intake as thats when the flaps activate for the TQ change over. But also people see fuel related or 02 related issues.
You can always log the fuel side to see. Is this something repeatable over and over.
Thank you for the response!
Yes it a consistent thing I have noticed since I bought the car.
I am waiting for a VCDS from Ross-Tech, would that be sufficient to look into any fuel pressure or IM codes? I would to scan the car and get a baseline.
The car runs great than this though and its the only V10 S6 in here, beautiful car and the low end torque is in the big block territory!
Thanks for your help and I will send a message when I get a scan done.
Cheers
Has anyone replaced the hose 07L103217B? Mine is broken where it connects to the intake so am replacing.
When I blow thru the MAF side I confirmed the check valve is working.
Being it was broken at the intake hose connection, I can assume the measured air thru the maf “may” have not helped the cold start misfires
I replaced this with the OEM part last winter - pretty much replaced all components of the PCV that I could reach at that point. Hope this solves your issues with the IM leaking!
