Does anyone have any other suggestions for what I could watch

Disconnect the return hose from the fuel injection pump to the diesel filter and check if a visible stream of diesel fuel is coming out when the engine is cranked.

If not: Check fuel lines.

Have you checked with VAG Com to see if the WFS (Vehicle Speed Fluctuation System) is active? Do you have the original speedometer installed? Or is the immobilizer deactivated in the engine control unit?

Best regards.

Tom.

Hello,

Okay, I disconnected the return fuel line and diesel is coming out.

How can I check with VAG-COM whether the WFS (Warm Function Start) is active?
It should normally no longer be active.

..but because the exhaust manifold is not attached, it should start after a longer cranking period.
It smells strongly of diesel, but it doesn't actually do that.

Hello,

It could be because the particulate filter (DPF) isn't actually regenerating, and the diesel fuel is just being circulated within the system.

So, as Matthias already mentioned, let's check the wiring of the PDE (Power Distribution Element) (power supply, connection cables at the MSG swapped, causing the PDE to close the bypass at the wrong time?).

Best regards, Jochen.

Hello,

Today, I (or we) got the ARL running.
I'm almost afraid to write about what it was related to .

The inlet hose and the return hose were reversed.

The wiring was correct after all.
I just need to figure out why the gas pedal isn't working.

"Nevertheless, thank you very much for all the tips."


Best regards, Franz.

Yes, yes: if attention wanes, the "devil is in the details" will mercilessly strike.

Still, it was nice of you to tell us what the cause was.
