EGR/NO BOOST/VACUUM ISSUES 2007 Audi A3 TDI

[Jaques.s]

Hi Guys

Need some help with fault finding, had my car with 3 garages and no one knows what's the issue..

Egr vacuum pipe is on then the car smoke and have no boost...computer say insufficient air flow to EGR.

If I remove the vacuum pipe on the EGR Valve it's not smoking, the boost is there but then the car struggle to start..

I have replaced EGR Valve and the Black Vacuum box thing..

Any ideas ? I'm almost giving up here.

Are the vacuum pipes routed correctly? Also make sure the small vac pipe that's going to the airbox is not blocked or kinked.
