Lambda errors
 

While doing a scan tonight to reset teh airbag light I found these little buggers ,I had reset them a little while ago but they have came back ,Any ideas why both of them are showing issues ?

VCDS-Lite Version: Release 1.0
Control Module Part Number: 4D0 907 551 M
Component and/or Version: 2.8L V6/5V MOTR AT D02
Software Coding: 04153
Work Shop Code: WSC 00681

2 Faults Found:

16538 - Oxygen (Lambda) Sensor B2 S1: No Activity
P0154 - 35-10 - - - Intermittent

16518 - Oxygen (Lambda) Sensor B1 S1: No Activity
P0134 - 35-10 - - - Intermittent

Do a log on lambda voltages. It is most likely duff lambdas or running too lean.

Can anyone tell me the part numbers for those ones and where they would be located ?

Here is a list of options from Vagcat for a facelift car. I'm not sure how accurate this is.
Hopefully the Librarian will be along shortly with the correct part no. (35 just refers to the picture label, its not a part of the number)

(35) 078906265M
lambda probe / (in front of catalyst)
/ 6 cylinder

(35) 077906265J
lambda probe / (in front of catalyst)
/ 8 cylinder

(35) 06A906262BF
lambda probe / (in front of catalyst)
cylinders 1-3 cylinders 7-9 / 12-cylinder

(35) 07C906262G
lambda probe / (in front of catalyst)
cylinders 4-6 cylinder 10-12 / 12-cylinder

(35) 078906265R
lambda probe / (behind catalyst)
left / 6 cylinder

(35) 077906265AA
lambda probe / (behind catalyst)
left / 8 cylinder: AKB,AKC,ARU, AUW

(35) 078906265Q
lambda probe / (behind catalyst)
right / 6 cylinder

(35) 077906265T
lambda probe / (behind catalyst)
right / 8 cylinder: AKB,AKC,ARU, AUW

(35) 077906265H
lambda probe / (behind catalyst)
left/right / 8 cylinder: AVP,AYS,BCS

(35) 07C906262F
lambda probe / (behind catalyst)
cylinders 1-3 cylinders 7-9 / 12-cylinder

(35) 07C906262E
lambda probe / (behind catalyst)
cylinders 4-6 cylinder 10-12 / 12-cylinder

Sorry I should have said earlier ,mine is a PF 2.8 1998.
Are the codes different ?

Here is a list covering the following engines:
engine control unit / 'MPI' / 6 cylinder:
control unit for cruise control system / lambda probe / anti-knock sensor / * only order electronic * * components for immobilizer,* * including details of veh- * * icle chassis number, for * * items which can be fitted * * immediately by dealerships *
/ AAH,AEJ,ACK, ALG,AFB,AKN

(41) 078906265A
lambda probe
/ AAH,AEJ

(41) 030906265BH
lambda probe
/ ACK,ALG
