Well I went to the garage, and the outcome was...
- Mechanic took it for a test drive and heard the knocks so brought it back to the garage
- It was then put on the ramp and they had a look, his reasoning (for now) is that as it has the bigger wheels and the stiffer suspension, the bushings are still pretty tight and it could be them that are knocking.
- But he has said give it 500-1000 more miles (I have done 800ish so far) and if it hasn't stopped take it back and they will take it apart and see whats going on.
- He noticed the squeak on the door and apparently its a common problem that the door seal rubber is very 'dry' so when the doors are closed and the car is moving about they squeak together, causing that infuriating noise!! So he had some 'door seal grease' which he put on and after a mile or 2 of it being worked in, gone!! Amazing!!
Garage is W.B.Cowan just outside of Edinburgh, couldn't fault their service through ordering -> delivery -> this.
Just have to wait another 1000 miles and we'll see if anything comes of it. Keep us updated it you are getting bits replaced.
