I noticed a small LHM leak from the near side rear suspension ram bellows today.
On investigation, it seems that the metal brace under the ram was bent.
I am 99% sure that was not the case before the MOT test.
Not able to see the car while being tested I think the tester must use this area to jack up the rear of the car.

To remove the bend in the metal bracing plate, I used a metal angle with a bolt and washer that just goes through the existing hole, and tightened the nut, till the plate was straight again.

May be a good idea to check this area after your MOT test, as this has happened twice now.
