Oxygen Sensor Replacement B3S1 2008 S6 v10

[Dreezzee]

This thread says B3 S1 can be changed in car.

Engine drop question

That is a great time to assess if you are going to pull the prone to fail cats out. Also check in the spark plug tubes to see if there is any standing oil. the cam ladder gasket can leak and when that happens that too is a motor out job. It’s a bit of work so if you can do it now that would be best. Also just a good time to check all of the gaskets from oil pan to valve covers as now is a much better time to get to these things.

Entirely depends on your budget and mechanical ability.

1. Oxygen sensors depending
   1a. Three of the O2s are unreachable with the engine still in the car. They are bank two (cylinders 4 and 5) sensors 1 and 2 along with bank four (cylinders 9 and 10) sensor 1.
   1b. Three of the O2s are annoying to replace with the engine still in the car but doable. They are bank 1 (cylinders 1-3) sensor 2, bank 3 (cylinders 6-8) sensor 2, and bank 4 (cylinders 9 and 10) sensor 2.
   1c. Two of the oxygen sensors are extremely easy to replace. They are bank 1 (cylinders 1-3) sensor 1 and bank 3 (cylinders 6-8) sensor 1.

Does anyone have a write up on bank 3, sensor 1?
I haven’t looked at on the lift …yet.

Thanks!

@Dreezzee

Does anyone have a write up on bank 3, sensor 1?

Well… I only have the German SSP376 for Audi 5.2l V10.
They only write about 2 banks. Left and right 5-cyl. banks. But if we can agree that bank 1 is cyl. 1-2-3, bank 2 is 4-5, bank 3 is 6-7-8 and bank 4 is 9-10 then it should be as follows…
Seen from inside the car looking out towards motor…
Left side is cyl. 6-10 where 6-7-8 goes into cat. #3 with O2 sensor 3 G285 bank 3 before cat. and O2 sensor 3 G287 bank 3 after cat. Cyl. 9-10 goes into cat. #4 with O2 sensor 4 G286 bank 4 before cat. and O2 sensor G288 bank 4 after cat.
Right side is cyl. 1-5 where 1-2-3 goes into cat. #1 with O2 sensor 2 G108 bank 1 before cat. and O2 sensor 2 G131 bank 1 after cat. Cyl 4-5 goes into cat. #2 with O2 sensor 1 GG39 bank 2 before cat. and O2 sensor 1 GG130 bank 2 after cat.

G39, G130, G286 - engine out.
G131, G287, G288 - difficult
G108, G285 - easy

Bank 3, sensor 1 is the G285… the easy one before cat. #3 (left most furthest back cat.)

I can print/patch and scan the images of the setup later if you want?

[Dreezzee]

I would agree that we are talking about G285.
I would love the print out.
you can email it to me if you’d like.
drewwattles@sbcglobal.net

thanks!

[kimenemark]

Sorry… got busy. I have sent an email.

Have a nice weekend

Regards Kim

[Dreezzee]

Got’em! thanks!

[Dreezzee]

This was a legit 10 minute job. I put the car on stands, removed a crossmember (4 bolts, 16mm socket) and then removed the 02 sensor (China Freight offset O2 socket).
New 02 in, crossmember bolted in and car on the ground. No more CEL.
Hopefully I can get it smogged this week…

[Douglassc6s6]

You mind posting that on her or sending me that as well?

[kimenemark]

Not sure if I’m allowed to post it here… I have scanned the SSP, printed the 2 pages, “spliced” them together, corrected a couple of textual errors and scanned the important parts… but nevertheless I guess Audi’s copyright still stands

I can however send it to you as well… mail?

[Dreezzee]

I emailed the pages you sent me.
