I tried fitting a set of bosch hids to my mums a3 yesterday.
Basically to cut a long story short, they brought up the headlamp error message on the dash and now the wipers dont work
I asked the seller of the hids if they would be ok with a 54 audi a3 and they told me that they would be fine.
Im gonna talk to audi about the wipers tomorrow and get my money back for the hids.
Can anyone suggest some hids that they have and know to work fine with the audi ecu?
