I am trying to find a diagnostic scanner for the 99 Arnage software. I have tried the BMW version 1.4 which was used for the E38 series BMW but this has limited functionality. Can anyone recommend a scanner that can access all functions, engine, abs, ride, airbag?

I doubt that any non-dedicated product will access the ride related data. But there should be a number that can easily do all of the OBD-II standard codes along with ABS and SRS (airbag).

I have an acquaintance who has a 1999 Seraph, and I'll check with him to see if he found something that can do at least OBD, ABS, and SRS in their entirety.

Hi. It's possible that you only have OBD1 on your car? Not sure what the rules are for non-UK. In the UK, it looks like they did OBD2 and then slipped back during the engine change from the BMW unit. I have the 89th Red Label built but it has engine number 1 fitted. It's OBD1 and only the Bentley scanner will work - fortunately the local specialist is very happy to help if and when random things seem to go wrong!

Does it work on the 2000 model year ?
Gleaned from the wiring diagrams this list shows what is physically connected on the car (Arnage and Seraph) to the obd plug on the left and what is physically connected on a cheap chinese Vag scanner on the right. Pre 2003 are not obviously responsive to the later Vagcom scanners except for emissions ( engine). So to clear an airbag warning would require pin 7 (iso 9141) to be connected to pin 3. I use a break out box for ease of use. That is because the cheap scanners do not have a multiplexor (fancy name for electronic switch) built in. Pin 15 wakeup L line is not used on the Arnage or Seraph range. It should be clear that pins 1,2,6,8,10,15 are of no interest to us. Looking at the factory software scanner coding for pre 2003 cars a lot of stuff mentioning BMW keeps popping up. I have not had the time to follow this up further. Mine is a 2000 Red Label.

Hello Tusabes,
I have found so far that the 2000 responds to ISO 9141, KWP2000, KWP1281 protocols. The 1999 is OBD11 then they revert to OBD1 and then post 2003 back to OBD11. I have not used the BMW scanners but I have noted that the ones covering earlier cars use ISO9141 which is promising. On the engine OBD1 correctly reports a lot less than OBD11.
Using the original airbag example, if the BMW scanner outputs ISO9141 to scanner pin 3 when the software says "check the airbag" then dealing with the airbag should be automatic. Or it may be that like the VAG5054a pin 3 is not connected on the scanner so that the physical connection has to be made to a pin outputting ISO9141 ( pin 7). I used the Vag5054a because the chinese copy came with V19 Bentley software. I have the BMW V2.20 software as I intend one day to have a root through it. Pretty well all manufacturers push the latest scanner which is of no use on 22 year old cars.

Yes the wiring checklist above shows airbag on pin 3 from 2000-2009. The only reason it does not mention pre 2000 cars is that I could not be bothered checking the wiring diagram. I can use a £5 scanner to reset the airbag by joining pin3 to pin7 and issuing the clear dtc command. The 2005 should be even more willing to respond to any VW scanners as by then they had the Bosch engine ECU(OBD11) and (I believe) they had not yet gone to full CAN. The 2000-2003 used the Zytek 5 ECU (no relationship to the Ford Zetec) engine ecu.
If you open your scanner you can soon see if pin3 in the scanner is physically connected or just connect 3 and 7 externally for the check.

I have noticed, and it may be worth the mention, that the airbag warning is often triggered when you place eg a heavy coat or a laptop on the passenger seat. The lack of weight seems to confuse the ecu as possibly a child or baby is in the seat but definitely not an adult.

My car is 99. To be clear, are you referring to the circular connector next to the ECU in the engine compartment? Can any damage be done to the ECU by connecting these pins together?

Sorry for the delay. We are the largest quarantine centre for Ukrainian Refugee pets and we are busy!
No that is not the OBD socket. By law all OBD sockets must be reachable while seated in the car. It is the 16 pin socket just below the knee roll. You can get plenty of pictures of what an OBD socket looks like online. Data lines are safe to cross connect but absolutely do not inject pins 1, 16 (12V power) into a data line. Much less risk but don't do it is inject pins 4,5 (Power negative earth) into a data line.
