Intermittent issues - coil light.

Hey all,

We've recently purchased a 2018 T6 and seem to have a couple of weird issues that we're struggling to get to the bottom of.

We've had a couple of codes, some of which pop up more often than the others. The most common one is P0402 EGR Excessive flow Detected. EGR was replaced 9 months ago. The other faults are listed below.

P0236 - Turbocharger/supercharger Boost Sensor "A" Circuit.
P2279 - Intake Air System Leak.
P13D6 - Glow plug 3 pressure sensor.
P0402 - EGR Excessive Flow Detected.

The faults appear anywhere between 0-3 miles and sometimes don't come back on once the van is up to temperature and we've turned it off and on again. We've also notice a weird rattle and whoosing noises at around 1500rpm before the coil light comes back on but again, it's intermittent.

The vans been back to garage once and they replaced the MAF but it's a backstreet sales only outfit and I fear they don't really know what they're doing.

Any advice would be much appreciated.
