This is what it says on the failure notice - '006 - Offside inner (sill panel at rear) Suspension component mounting prescribed area is excessively corroded [2.4.A.2]
The other things it faled on were - basically no water in the washers (my fault I know), Horn does not function; Hazard warning lamps not flashing in phase, with ignition on; Hazard warning lamps not flashing in phase, with ignition off.
******* great.
I just would rather pay someone from here then a garage tbf.
