Question on codes after 850 me4.4 upgrade

[hausmeister]

Hi

I have upgraded my 1995 850 t5-r with an me4.4 ecu from ARD. I opened a topic some time back about adding obd2 port (which escalated because people obviously can't read).
Anyway, I got around to installing the OBD2 Port and was able to read the codes.
(proof of concept: http://imgur.com/NoEmrNU )

Now, here is my question: some of these seem to be because it expects sensors that simply are not there in the older 850. Can you help me figure out if these need looking after or if this is simply a problem from me4.3 -> me 4.4 conversion?

The original ECU did not have any codes set.

444 Accelleration sensor signal (The trans was replaced and the speedo sensor is spliced into abs. could be the cause?)
335 MIL-Request TCM link failure
442 Baro sensor signal (I guess not there on 850?)
447 control valve airpump
621 Tank pressure sensor
251 AMB Temp sensor signal
522 Rear HO2S heating (ARD told me they removed the rear O2 sensor from the ecu... )
153 Rear HO2S signal

I think most of these are not "valid".. (like baro and rear O2)
Seems to fit the list on http://m44.wikia.com/wiki/Category:M4.4 ... rror_Codes

Ah sorry. I was getting cloudflare errors, but it seems it did indeed post... If a mod could delete the other duplicates I would be grateful.

444, 442, 522 and 153 are just routine variables in the tune, ARD failed to disable them. Surprisingly shoddy and they can easily fix it, but it requires a re-flash (or a properly flashed ECU sent to Austria). The others may be too, but I am not familiar with them.

I checkd against the wiki and these are the only 2 I can't match:

447 control valve airpump
621 Tank pressure sensor

@ARD
I agree. It still works fine and is a huge improvement, but they had all the information and should have disabled these checks. I am slightly disappointed, but not a huge issue. Maybe If I need a retune I will ask them to fix that also.
