Hi all,

I've recently purchase VCDS in an attempt to get to the bottom of my Transporter woes. I have a T6 150hp DSG, and I've had a whole host of engine related issues. Codes below.

P0236 - Turbocharger/supercharger Boost Sensor "A" Circuit.
P2279 - Intake Air System Leak.
P13D6 - Glow plug 3 pressure sensor.
P0401 - EGR flow insufficient detected.
P0402 - EGR Excessive Flow Detected.
P0101 - Mass or Volume Air Flow Circuit Range/Performance Problem

P2279 seems to be the most popular and my most recent full scan is below. Sometimes I get a couple of the above codes come on in tandem with P2279, especially P0402 - EGR Excessive flow. I took it to a local garage who said that they smoke tested and didn't find any leaks but didn't have the ability to delve any deeper. The did also say that the N75 boost control solenoid valve was very hot like it was trying to overcompensate for a boost issue. Swapping that with another sensor produced the same problem.

Based on this and the below scan, what would be my next steps? Many thanks.
