lambda sensors

[ettore]

Hello!

After removing engine my RS6 have problems with transmission.

My RS6 have these faults:
16515 Oxygen (Lambda) Sensor B1 S1: Signal too Low
16534 O2 Sensor Circ.,Bank2-Sensor1 Malfunction

Do I need to replace lambda sensors or is it possible to make Check engine light eliminator or something else?

I dont want to remove engine from my RS6 one more time.

Sorry to hear the bad news.

If you read the list...you would know that there are a few items that must be replaced when the engine is out of the car.

02 Sensors
EGT Sensors
Timing belt+waterpump

Are just a few.

Having said that, you can replace the 02 Sensors without pulling the engine if you have good mechanics. Have them try

timing belt & waterpump replaced
what is EGT sensors?

Exhaust Gas Temp sensors

Another hard one to get at with the engine in the car. Book says you have to pull the engine to change 100 dollar sensor.

I replaced lambda sensors, but my RS6 have the same problem and faults:
16515 Oxygen (Lambda) Sensor B1 S1: Signal too Low
16534 O2 Sensor Circ.,Bank2-Sensor1 Malfunction

These faults appeared after engine removing from my RS6.

Any ideas?

Pinched the wiring harness somewhere?

Hey DHall1, let me know if you can find them for that price. I've only seen them for around $250~$300 each.

Clarify,

I have no idea what each sensor costs. My guess is that a egt sensor should be around 100.

If its really 5,000 then I stand corrected

if you get these codes, you do need to change both sensors. go onto ECStuning and order the O2 sensors or go to your dealership to get them . I recommend ECS.

the faulty O2 sensor will kill your gas mileage and make your car run like shit

I replaced 02 sensors last week

I see. then it's very weird you still have the codes. how does the car drive and how is the fule mileage?

when engine is cold transmission twitch but I can switch gears with tiptronic
when engine ir warm transmission twitch and goes to safety mode
