No. I have done it twice and one time it was about 90% full and other about half full.

Ainair came out and fixed it for me yesterday, car now drives like a dream after the new fuel pump, thanks, Ainair - top work.

Nice one

You going to bring one of your fleet to AITP next weekend?!

So was it just the pump incorrectly seated in the end or other related issues not helping?

I will let Ainair answer that one, I wasn't at home when he worked on the car, and as I've been busy I've had no real chance to speak to him.

Loving the instant non drive by wire throttle response, and the lovely naturally aspirated V8 power delivery, it's so smooth, and no matter how much you floor the throttle, it won't feel violent like an S8 might, I've always loved the PF D2 A8 4.2 power delivery/setup.

The owner still hasn't found the V5, and the V11 reminder he gave me is two years old... So can't tax it until that's sorted, so AITP is probably likely to be in the RS6, if I come at all as I am mega busy.

You might as well apply for a reg document yourself - it'll take a few weeks and you won't be able to tax it till after the reg document arrives anyway.

V5s tend to be lost for good unless they suddenly remember where they left it

Well fuel delivery unit definitely has been replaced before, there was a (stock) number painted on it, there was also unusual level of corrosion on pump terminals and filter mesh. So I would say that it has been in storage for a long time or in unsuitable environment which caused corrosion. My best guess would be that pump inside was corroded as well which caused it to work sometimes and not others and also introduced extra resistance and caused it to draw extra current blowing fuse. When I got to it it was open circuit, probably burned motor coil because of extra current flowing through it.


As far as taxing goes you can go to local DVLA office and tax it straight away as long as you have insurance and MOT. You will need to apply for new logbook at the same time and if you have not got green slip from old logbook it will cost you £21 extra. V5 or taxing is not a proof of ownership. V5 is for registered keeper, it does not prove ownership, if anybody is happy to take responsibility and pay tax DVLA does not have anything against it.

Have they relaxed it in recent years? I can recall it being a major pain in the bum when they introduced continuous registration and taxation when buying at auction as no reg doc basically meant parking the car up until the reg doc arrived back with you before you could then tax it

Good news it's sorted - did the pump etc get replaced again with a new one this time?
