i have a cracking like knock sound when pulling away in my A6, or letting off/applying power at low speed.
Seems to be coming from drivers side. Car is due MOT next month and I'd like to try sort it before then.

Any ideas where I should be looking?

how much did they cost to get done? I've booked it in for early MOT on Monday as I'm going on hols in it on good Friday so don't fancy any problems.

I just replaced my driver side its like wish bone arm, ball joint was gone, and i was getting bad knocking noise at driver side. Thats arm is near top off suspension, there is 2 there. I would recomend to check them properly! They about 30£ each, tops...

Just checked through my paperwork. Sorry, it was the front lower arms I had changed. There are 4 bits in there, upper and lower front and rear. You can get cheap ones, but I went for an OE equivalent. My mot was £45, bits for service and the 2 lower front arms were £209, and £80 labour - so mot, service and the 2 arms cost me £334 - but as I said, there are cheap arms and there are expensive arms. I know someone who changed all 4, and the following year 1 failed the mot

As above, do not buy cheaper ones. Lemforder or genuine Audi...

Well, it's been for MOT today and has passed. It did get an advisory on slight play in upper control arms so suspect that is where the problem may lie!
It's also due a pair of front tyres (which are being delivered today) so think I may just get the wheels off, have a good look around it myself and order the bits to do at my leisure.
I'll have to look out for a guide!

I've also got a pair of rear lower arms to do on my B6 A4 at some point.
