The headlight cluster on an A2 are almost impossible to access the usual way - from the inside. I have managed to change both near and off side headlight bulbs but trying to renew the nearside front signalling bulb has defeated me. My local AUDI garage cannot advise me how to do it on health and safety grounds!!!!! apparantly danger of electrocution!!- but they would change it for me for the sum of £25.00 +VAT Grateful for any ideas.
