Hello.

Okay, here's a really silly question.

What can I do if my car won't start?
Okay, I just mean letting the starter motor turn the engine over.

Because I need to remove the air from the oil supply line to the turbocharger before I can run the new turbocharger with the engine.

Is there a fuse or plug that can be removed?
If so, where??

And if possible, without any strange error codes appearing in the error memory again?

Passat 3BG, 1.9 PD AVF, 2001.

Hi there,

Remove the famous Relais 109. Then it won't start, and the control unit won't be able to store anything either.

hi,
Does a PM motor still have the 109 relay?
I don't think so.
I see only one way to disconnect the connector from the PD elements and then clear the error memory.
greetings

Hi,

According to the documents I've gathered so far for my new PD-Polo, at least the relay 109 is still present (I'm still waiting for the car...).

You can start the engine normally and then let it run for about 30 seconds at idle.

You've already filled the oil reservoir with oil, which is enough until the oil pressure builds up!

They don't break that easily!

Regards,

Manuel.
