Thanks for posting, I'll add it to my to do list.
Would it be possible to access by removing a wheel arch liner ? |

yes for the front plug
however here is one which is sandwiched between the inter-cooler and the pump itself this is difficult with the **** guard off i would say even more so with just the wheel arch removed |

Mine has had a new pump fitted - under warranty so no idea of cost but don't think it was a huge job.

damtom85,
i see it was summer when you changed your pump, don't suppose you noticed if the blowers got warm? mine are all but stone cold, only just noticed as the weather has turned, and the only error thrown is the same pump error as yours. makes sence, i think, but don't want to waste £100 on a pump if it's not the fault cheers Albert

Hi.
car gets warmer much much quicker than before, I bought used one for £40. audi fits them in A8, A7, A6, A5, A4 so it is easy to find them. PS. I changed mine 2 weeks ago not in summer. I knew what was the issue but didn't have time to do it. however now weather turned cold I needed to change it. Done it in 20 minutes, difference is huge.
