2009 Audi S5 Manually Turning Engine Over

[jonmartinez223]

Vehicle Make/Model : 2009 Audi S5
Location: What state/country the car was driven primarily : Denver, Colorado
Mileage/Date in which CB was discovered : 67,0000
Oil used : Castrol Synthetic
Oil Change Interval : 5k Miles
Fuel Used : Sinclair / Costco / Conoco 93 Premium
How short/long are your trips on average : 5 Miles - 25 Miles

Noticed my car running poorly. No Engine codes or anything like that. Just purchased it at 60K miles and the previous owner has had it since 10k miles. He said he never really stepped on it. After noticing my car running a little sluggish, my brother and I decided to open it up and take a look at the Intake Valves. No surprise that they were in rough shape, and full of carbon. We followed a few DIY to open it up. At the current moment, we are a bit stuck because 5 Valves are closed but 3 stayed open. It is an Automatic Audi S5 and the Parking "hand break" was enabled prior to opening the car up. Does anyone have any ideas on how we can get the last 3 valves to fully close so we can continue cleaning them? Any help will be greatly appreciated

you need to clean the the open 5 and then turn the engine with this. itll open the 3 that were closed , and close the other ones that were open. it fits right in between the 8 bolts http://www.ebay.com/itm/Audi-Cranksh...739336&vxp=mtr then clean the last 3.
its easier to turn if you unplug ur spark plugs

Would I need to remove the whole front of the car like it shows in the picture? There is very little
Space between the radiator fans and the actual engine, so I'm not sure how I'm going to get the socket and ratchet down there. Thank you for the link to the socket, btw. Couldn't find it anywhere.

you should be able to squeeze a breaker bar in, if not from the top try going from under

I'd be impressed if you can do it without pulling the core support forward. I couldn't even fit my hand up in there. I just put the car in first and rocked it until the valves were closed.

quick update: we actually ended up putting everything back together. We cleaned 5 out of the 8 cylinders. Car turned on and idled great. We are digging back into the car later this week again to clean the other 3. And this time I will make sure to turn off the electronic parking brake and we will leave the car in drive to push it if we need to close any of the 3 valves that may remain open. Pictures and notes coming soon!

You're not going to be able to turn the engine over by pushing an automatic while in drive.

Would we forcefully need to use the turning socket tool in order to move the valves?

I'm not sure if there is an easier way to do it on these cars or not, but normally yes, you'd want to have a socket on the crank. You may be able to turn using an accessory pulley. Bumping with the starter might be an option too, but you'll be rolling the dice on where it stops and how it leaves the valves.

The reason I said you won't be able to do it by pushing it, is that since your car is an auto, your torque converter needs quite a bit of revolutions per minute in order to transfer back into the engine because it does it via fluid. I'm not sure you'd be able to push it fast enough.

I had someone else recommend starting the engine with a remote starter switch while the battery is connected. I believe you connect it to the solenoid. Here is the link :https://www.ecstuning.com/Audi-B8_S5...016/ES2840947/

That should do the trick, it just might take a few revolutions to get it to stop where you want it.
