DTC code 8194; what does it mean?

[mccrj]

The engine management light came on yesterday morning after I started my car A4 Avant 2.0 TDI 170 quatrro S-line Special Edition.

I plugged in my Celtic Tuning eMotion unit to check if any DTC fault codes were present. It showed up a single fault code of 8194.

The ECU has been remapped (FastRoad 207bhp) using the aforemention Celtic Tuning unit.

Does anyone out there know what DTC 8194 means?

It is not a VAG, HEX or a P code so it is meaningless to me, it must be a machine specific code and would need converting into hex, VAG or P

[mccrj]

Thanks for the response.

Do you mean HEX as in hexadecimal?
If you do then 8194 is 2002 in hex, if not then please pardon my ignorance!

[Crasher]

Yes but a hex code of 2002 does not come up either, for example VAG code 17965 would be 462D. I imagine 8194 is a code specific to your code reader and I don’t know what it is, sorry.

The 8194 code is to do with a blocked DPF as confirmed by the dealer this morning

The code is also mentioned by patrickhorton in the Cleaning a blocked DPF thread.

I found it by searching for 008194 rather than 8194.

[Crasher]

That is a good code, I tried it as 08194 but I never thought to try 008194.

[mccrj]

Other codes that also showed up were 001137 and 009299.
You wouldn't happen to know their meaning would you?

you should look on ross tech wiki
but those codes relate to the dpf

Spot on!
Thanks very much.
