Diagnosis dongle

Hi.

Is there something that can always be plugged into the diagnostic connector, which receives power from it and can display certain information?

I would like to see an indicator showing whether the engine is currently in a regeneration cycle.

With software version 0420, I was still able to hear it and let it take a little tour around the city.
"You don't hear that with the 1184 anymore. But I don't like having to connect the laptop every time, or waiting for the DPF warning light."

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hello Martin,

I've already tested something similar for K-Line, but unfortunately, it wasn't very stable, which is why I'm not offering it at the moment.
Unfortunately, I'm not aware of anything similar for CAN at the moment. Is it still possible to access your car's engine control unit (ECU) via the K-line?

Best regards, Rainer.

According to my information, you can still access the engine with the K-line, and possibly also something else, I think it might be the transmission.
The rest will be communicated via CAN.

I haven't tried it yet with my homemade optical coupler device.
I'm not sure if I still have such an old version of VAGCOM.

But a K-Line item would be awesome.

It's no problem, Martin; you can build something like that yourself .

However, there's a problem because the solution you linked doesn't work on this vehicle. You won't get very far with KWP1281 when dealing with an EDC16 system...

"...although I would approach it differently. Why always have to attach something to it; wouldn't it also be possible to see retrospectively when it was regenerated?"

Okay, so it seems like KWP2000 is the way to go...

Best regards, Rainer.

Excavations...

I want to be able to let it finish its regeneration cycle during a trip, even if it has already started.
Due to my driving pattern (driving mostly in the city for days, but then also occasionally long distances), I still frequently experience overheating issues within the city.

Then I would like to give him his "fryer round."

A simple LED would be sufficient. Ideally, I'd like the DPF light to turn green when it's regenerating normally, but that would probably require "some" effort.

If you knew whether a CAN message contained specific information, you could build such a device using an Atmel AVR processor or something similar.
That wouldn't be an excessive amount of effort.
