Hi down there! I also have an MGTF built in 2002 and also have Knocking noise! You seem to have done all the checks I have done, apart from taking the drivers door apart. I THINK my noise is coming from inside the door, but sometimes sounds from further forward. There are some brilliant "How To" guides on the www.MG-ROVER.ORG site, I intend to follow their instructions for "Central locking mechanism replacement how to" guide to remove the door trim etc. to search for loose actuating arms between the inside door handle and lock.
I suspect that "OUR" problem is more suspension related however (bad news!) but as both vehicles have passed an MOT test or the Aussie equivalent and then some, by sound of things, hopefully nothing is just about to fall off!
Have you been able to look at the underside while the car is on a ramp/4-post lift? I had some concerns about brake efficiency, so paid my local garage to repeat a brake test and let me have a dekko. I will try to attach a picture:
I wish you good hunting and will keep a close watch on this thread!
Thanks for asking the question
Regards
John E
