	How to identify if wideband equipped from software side? « on: January 18, 2016, 01:22:08 AM »

Hi,

friend of mine bought a TT 8n with AUM engine. Car has two O2s which usually means front O2 is wideband.
Thats where this question came to my mind.

So as a rule of thumb if i only have the software available: If read O2 in Eskonf = Wideband Huh

Is this true and/or are there better ways to identify how many O2s a car has?

Two o2s doesn't mean one is wideband.

However, to identify how many from the binary:

CWKONLS

Code word in % PROKON :
Sensors present upstream of the catalyst --->
Bank1: B lsv by Bit 0 = 1
Bank2: B lsv2 by Bit 4 = 16
(gives 17 as the sum)

Sensors present downstream of the catalyst -->
Bank1: B lsh by bit 1 = 2
Bank2: B lsh2 by bit 5 = 32
(gives 34 as the sum)
For all 4 installed seensors: CWKONLS = 51

00110011

NA/NA B2R/B2F NA/NA B1R/B1F
00 11 00 11

00000001=Just Bank1 front (4cyl)------>CWKONLS=1 no rear
00010001=Bank 1 and 2 front (v6/v8)--->CWKONLS=17 no rear

One for the more knowledgeable to confirm but is CATR only enabled on wideband cars? (Cars with a real egt sensor) Or do wideband cars exist without an egt sensor too?

032HN and derivated is a good example for wideband without egt probe i think

There is a 512kb 1.8t beetle binary.
The 12v vr6 is also 512kb and wideband.
