Evening all,
Forgive me for posting in this section with my Mk4 R32 (86k on the clock) troubles but this is where the cool kids hang out
In all seriousness I know there are a few members in this section who will most likely know the answer to the problem.
About 3 weeks ago I fitted a de-cat system to the R32 and as expected 40 miles later the engine light came on. It was booked in for an R-Tech map the following week so I wasn't worried about it and didn't even check the fault code as I knew it would be relating to the missing cats.
After my R-Tech map Niki coded out the rear lambda emission part and off I went.
About 300 miles later I hit a bump on the motorway and literally a second later I got a beep and the EML come on again.
I scanned the car and I had these codes: -
17584 - Bank1: O2 (Lambda) Correction Behind Catalyst
P1176 - 001 - Control Limit Reached - MIL ON
16538 - Oxygen (Lambda) Sensor B2 S1
P0154 - 008 - No Activity - Intermittent
I thought one of them would be a left over code related to the de-cat so I cleared them to see what (if any) came back.
Well approximately 300 miles later the EML has come on again and I only have this code now: -
1 Fault Found:
17584 - Bank1: O2 (Lambda) Correction Behind Catalyst
P1176 - 001 - Control Limit Reached - MIL ON
Looking it up on Ross-Tech wiki suggests the following: -
Possible Causes
Possible Solutions
Is my main option here to replace the lambda sensors?
Does anybody know what side/sensor bank 1 refers to?
Thanks in advance

Looking it up on Ross-Tech wiki suggests the following: -
Possible Causes
- Intake Air System leaking
- Oxygen Sensor(s) and/or Oxygen Sensor Control faulty
Possible Solutions
- Check Intake Air System for Leaks (False Air)
- Check Oxygen Sensor(s) and/or Oxygen Sensor Control (all of them!)
