Hello to you all for having this great forum!

I've read quite a bit of this problem and so far I've changed the IMF to a new one, but the problem still persists. Hard shudder at shutdown and also a kind of "rough"(very sensitive throttle response. I think it's the EGR you hear opening/closing) at 1400-2000rpm at low gears during the first 5 minutes after starting.

When looking at the flap with ignition or engine on/off, I should see it move, right? It doesn't. However, with a voltmeter I've found it to be power on 2 of the pins in the connector. As far as I've understood, the remaining 2 pins are for the sensors? Are there any way to check these?

Also, I have not yet cleaned the EGR valve. Could a clogged EGR result in this behaviour?

I guess the next step is to check the wiring. I read one post stating there might be a bad connection underneath the air filter box. The wires looks fine from the outside- should I open their black cover? Any places that are more likely to have damage than others, and do anyone have a diagram for where the wires go?

All the fuses looks alright and the coolant fans works good in VCDS - however the flap motor does not make a sound with the output test in the VCDS software.

Thank you for reading!
