	Wideband on AWT engine « on: December 23, 2022, 01:13:23 AM »

hello
I am looking for information to switch to wideband on my AWT from 08/2000

ecu 4B0906018R
with vvt and DBW

I have sensor 1 in front: 058906265C
strange it is often sold as a rear sensor?? is it not the right one?
and P0030 heating control fault.

I read the topics with the addition of 2 wires on pin ecu 52/71 ... could we create a complete noob topic?
do I just have to add the 2 wires and change the connector?

what are all the changes to make?
which probe model should I order for wideband lsu4.9? 5 or 6 wire?

I do not have much modification to do I know that my ecu was mounted on a4 a6 2000+ with wideband

thank you

It's a lsu 4.2 not 4.9. also it will have 6 wires on the ECU side and 5 on the o2 sensor. The 6 wire is for the calibration resistor

I ordered connector 1J0973733, 6 pins LSU 4.2

is there a reference better than the others for the sensor? in bosch I saw 17014
there are all prices...

It literally does not matter, the cable length is the main difference. Get Bosch 17014 it will be fine too.

Thanks Blazius, I suspected it but I preferred to be sure. I'm thinking of cutting the wires from my old probe, making a harness and just adding the 2 wires to the ecu in ghetto mode to keep my stock connection.

pity lsu 4.9 apparently more reliable and precise. From what I read it is a story of CJ110 eprom for 4.2./ CJ125 4.2/4.9 but this greatly exceeds my noob skills.

I'm really too stupid I had to look at my job during the night !! I had taken a picture of the rear sensor! I am in original wideband 06B906265D
0258007090
lsu 4.2
P0030 so it no longer heats it coughs cold.
I ordered a bosch 17014 but hey it should be fine.

sorry for the useless subject. it can be deleted
