That's a rather disappointing list of failures considering you went to the trouble of getting Marlin to prepare the car and present it for IVA.
I can kind of understand the brake bias issue as this always seems to be a subject of debate with VOSA as to what is, and what isn't accepted, but the other things are basic IVA (and the same as SVA) requirements that Marlin should have spotted and picked up in their own pre-checks.
I wonder who's paying for the retest??
