Some of you chaps have retrofitted cruise contol into your A3s. Do you know what I need to order? ETKA lists the stalk as 8P0 953 513 D 9B9 - "switch for turn signal, main and dipped beam, flasher switch for lights, parking light, cruise control system" - and 8P0 953 512 A 6PS - "trim, lower part for models with cruise control system". There is obviously some VAGCOM coding required too, but is there anything else? I fitted cruise control into my brother's GTI last week and when I was ordering the bits from VAGParts they had to check his chassis number to see if his steering wheel ECU was compatible. Does the same apply to the A3? Do you know what the cost of those parts was? I have to install it into a friend's A3 so I want to make sure I have all the info before agreeing to do it.
