Hi Team new to this and looking to run tests on my car which is a 2001 Audi AWP and the proto call KW1281 What to be able to reset throttle body and check fuel pump and injectors
what do I run with VCDS

I found this in a pervious post hope that we can do the above
Since that ECU uses the oldest of the VAG diagnostic protocols (KW1281), it only supports Sequential output tests. That means there's a sequence of tests programmed in the ECU and all VCDS (or any other scan tool) can do is to request the ECU to start that sequence, and once started, request the next test in the sequence. The ECU will send back a numeric code with each step in the sequence that VCDS will interpret to tell you what output is currently activated. There's no way to tell from a distance to know whether a particular output (such as the drivers side radiator fan) is part of that sequence. Note also that ECUs will often refuse to run the output test sequence more than once in a single key cycle.

As for label files and readiness scripts, I would imagine that an existing one can be adapted. I'll ask @Dana to take a look.

The ECU appears to be complete off-line in that scan...?

-Uwe-

PS: Please do not use the [Print] function in VCDS to post data here. The formatting it produces is intended for a sheet-fed printer, but it's much harder to read here than the native text that VCDS produces. That native text can be had using the [Copy] button in VCDS, or by opening any of the .txt files in your Logs or Scans sub-folder with Notepad and then copying the data to paste here.

Hi Sorry I posted the wrong scan, as this one the fuse #10 was blown, so it did not read the ECU. I will run another scan which is reading the ECU my bad. Will also do the above for the report see below did that work

Are you familiar with the blue bar at the top of the page? There is a video that should apply for your Throttle Adaptation.

As to the Fuel pump and injector test, such tests are usually incorporated into the Output Tests of the Engine Control Module. Have you had a look there?

Have you purchased documentation to service your car? That too is linked in that blue bar at the top of the page in the "How To" drop down.

Last, on the Ross-Tech website, if you do a search in the search box, I'm sure it will return a lot of information for your TT.

Hi Uwe / Bruce
Thank you for the update
I understood that the ECU with KW1281 did not give a lot of selection
I am not able to do Selective Output test which would have been great

Just wanted to make sure I was not missing anything :-)


Also can you update the thread as I HBD at the time so its not right

2001 Audi TT 150 HP AWP KW1281 Proto Testing Fuel pump, injectors and throttle body reset​

Thank you and have a great week
