As part of an ongoing investigation of performance of this forum, I have temporarily disabled the indexing of new posts in the forum search system.

To determine whether this has improved forum performance, please reply here if you have an undue delay (more than 10 seconds) when making a post.

I will revert the forum back to normal configuration...

Disruption to Parts Service

Hi everyone,
I've got a 2010 Dispatch and need the cruise control activating. I was hoping someone on the forum could do it for me in exchange for beer/wine :wink:
I would buy lexia but it seems that this is the only function I can't perform with the Snap-on versus Pro.

When the software queries the state of this particular input pin on the microprocessor, it doesn't know if it is pulled to VCC (high) or to Ground (low). Using a 'pull up' or 'pull down' resistor will ensure it is in one state or the other and uses a low amount of current.

On the board, the 10k resistor is a 'Pull Up' type.

What are these options?

Hello

I've got a 2011 B7 C4 and a Diagbox. I've been looking for something and came across these two options.
First one, what is an electrical key? It's set to 'mechanical' from factory.

Second, what is this option regarding ventilation? It's set on 'yes' by factory, but I don't understand what it does.

Thanks :)

But it works minutes after shutting of the engine. It's good if you're parking for a few minutes, but even then, it just blows in the hot air from the outside.

If there are any fault codes associated with the emissions or engine, the Engine ECU probably will not allow it. This is so it can protect the engine and its components.
