Thank you very much for your response. Please accept my apologies for my delayed response. It was due to several unprecedented factors. Anyway I wanted to acknowledge your help. Thank you.

Hi All, i am new to the forum and websit so please be gentle. please accept my apologies if this has been asked before but As I said I am new to the site and a new Audi owner so I am unfamiliar with your protocols i recently purchased an Audi A6 Avant which is a 57 plate. It was registered Jan 2008 so it could be a C5 model. After approximately a month of ownership the MMI screen packed in. After tangling with Audi uk Customer Services they agreed to a diagnostic check (FOC). I knew what the initial fault was, a broken rear windscreen washer pipe. The carnage amongst the electrics because of the water escape was ridiculous. Who in the right mind would route a water pipe where the escape of water could destroy what is essentially the central nervous system is beyond me. Anyway I digress. Audi Cardif diagnosed that the DSP J525 unit was not functioning. Further diagnostics to follow after this unit has been replaced. They wanted to charge me £1350 to sort it out. Naturally I challenged the cost with Audi UK because in my view it was a design fault. This was to no avail. Hhuuurrrrmmmppphhh! i am reasonably technically minded so I would like to replace the DSP J525 unit and the Washer pip myself. My questions are as follows: 1. Where can I purchase a DSP J525 unit without going through Audi or are there alternative options for sourcing said item? 2. The rear windscreen washer pipe seems to be a bog standard pipe. Is anyone aware of the specification of the pipe so I can buy it by the meter? 3. Any help and advice will be gratefully received. Thank you in advance. Bison
