Thanks everyone. Try and answer all the questions.
I am down South on the Hampshire Berkshire border.
Thanks for the tips, will give the earth strap and wishbones a check, the lower wishbones have been replaced, as they are quite new, and I was happy to see the underside is in great condition, but will check the ball joint covers.
I replaced the front light bulbs with newer brighter bulbs, got new gas struts ordered for the back hatch (taking an age to come), replaced the fluids, brake, coolant and oils, got the aircon re-gassed (worked fine, but was last done 5 years ago), spare set of alloys to get refurbished, but first need to resolve the EGR issue which has cropped up.
I am getting an P0401 error. I gave the EGR a clean (new gaskets etc.) and an in-situ throttle body clean, but has not resolved the issue. Looks like I will need to remove and clean the throttle body properly.
I also need to resolve the microswitch on the drivers door and passenger door, which only work when they feel like cooperating, made more difficult now that Audi no longer stocks the door mechanism and few second hand choices too, as only Audi classic in Germany sell it new, but they will not sell to the UK due to VAT issues! I am hoping to get some help from Tom on the forum with this issue.
I am genuinely impressed with how the little car steers, and even though the power output is modest, it really feels quicker than it should.
