Rear Coil Springs (MOT Issue)

Just had my car in for it's second MOT, it failed the first time round on the offside rear coil spring "Offiside Rear Coil Spring Mounting Insecure (5.3.1 (a) (i)".

Bearing in mind i'm on Eibach lowering springs, i found out that the damper that was installed on my car on that one corner was not the same as the others, and appeared longer than the rest, thus when the car is jacked up the spring was very loose.

Went out and bought a matching Bilstein lowered damper, fitted and just had it MOT'd again today, failed for the exact same thing.

I tested it before i lowered the car back on the ground and it the spring was marginally loose, but nothing that i haven't seen before and certainly much better than previously. It re-seats perfectly fine and has zero way of getting out of the mounting points.

Am i missing something? I've got both the rubber/plastic pieces at each end of the spring, surely there is no physical mounting to the car? I can't see any difference from the other side.

The garage haven't called me yet, but i can see it's failed when i check the reg. When they call i'm going to ask them to show me in person the issue, and i've printed off a snippet of the MOT regulations saying it should only fail if the spring fails to re-locate correctly when lowered.
 
Maybe no help to you, but back in my old Capri days we would drill small holes in the spring cups and wire-lock them into place.
Sounds a bit drastic and may not get through the more stringent MOTs now.

Surely just ask the tester what’s wrong and how you should go about rectifying it

I did that, they said they weren't sure what the issue was just one side was slightly looser than the other side. Helpful! Although i guess it was just an MOT not a fault finding excersize.

Anyway 5mins jacked up at home and i can see the very top of the spring has broken, barely visible with the top rubber pad. I guess because the shock was incorrect that the spring was doing all the work and hence snapped.

Issue sorted, new springs on the way!
 
Good stuff! Always worth jacking up the car pre mot and having a right good feel about the top and bottom of the springs for any bits that have sheared off
