Free repair for all A2s....

There is a design fault with the front doors of the Audi A2.
Being aluminium, the design of the driver and front passenger doors are light, but also slightly weak. The aperture for the front doors are large, not so much in length but in height. Much larger than the rear doors. Yet all four doors have the same number of hinges of the same design. The aluminium around the front hinges therefore suffer from larger amounts of stress (and the driver door; use too) and can result in cracking around the top hinge housing and hinge plate (but not the plate itself). As a result of this very common fault, Audi have created a new design for the bottom hinge and a fix for the top hinge surround.

The cost? Completely free. Audi UK have informed all Audi main dealers in the UK to be aware of this and if asked, to do the repair at an Audi approved aluminium specialist.
Now, some dealerships will plead ignorance to this. Swear it doesn't exist or worse, say your A2 is too old and you've missed the boat. Ask for the boss, if (s)he doesn't acknowledge this either, ask for his/her business card and say you are going to contact Audi UK.

Audi UK com down hard on dealerships that don't comply with their exacting standard requirements for not only work but also customer service.

So stand your ground, be brave in the knowledge that you are in the right. All A2s are covered.
This is as close to a product recall as you can get without actually going about recalling all A2s.

There will be images to follow to show what to look for.
(Even if you are not sure, the dealership should look for free. Al they have to do is open the front doors and feel around the front hinge. They and you don't need to take off the doors to look)
