Yes! I have another knocking from under the car, thought I heard it the other day and today I really did hear it again its the same sort of sound that I had when the N/S Drop-Link needed replacing in November last year.
The O/S was also replaced last April for its MOT and I think the knocking sound is coming from the O/S area, so has it gone again or is it another part that needs replacing ?
I have never known a car that suffers from so many knocking sounds, not had it 2 years yet.
