Ska Posted February 16, 2005 Report Share Posted February 16, 2005 Late last night the A8 broke down about 30 yards from a petrol station. I thought it may have been the lack of fuel...it was but because the fuel pump had given up and died. No response as I tried turning over the engine. The rescue guy put a direct live feed to it and no joy he also tried some easy start in the air inlet and the engine would start then cut out after a couple of seconds. Am i right in saying that the sender unit and fuel pump are the same unit in the tank on the drivers side? How much should this thing cost to repair? The 8 is with the stealer right now so they'll come into work with an extra A8 on the forecourt. Should I hope to get a loan car for something like this?

Ska Posted February 16, 2005 Author Report Share Posted February 16, 2005 OH Sh1t!!! The fuel pump on this thing costs over £500!!! ... ... Link to comment Share on other sites More sharing options...
cruiser647 Posted February 16, 2005 Report Share Posted February 16, 2005 Presumabley, not a case of the fuel tank running dry on one side? And the balancer pump is nadged? Link to comment Share on other sites More sharing options...
Ska Posted February 16, 2005 Author Report Share Posted February 16, 2005 I was low on fuel (about 10miles worth left)and trying to make to the petrol station; can you elaborate cruiser? I've only just found out that the A8 has a left and right tank, if it this balancer pump is that a different part to the main pump or does that do everything?

Botang Posted February 16, 2005 Report Share Posted February 16, 2005 It may be a bit obvious but there isnt a fuel cutoff switch on these, like they use in accidents. Maybe that needs resetting. Moral of the story dont run that low on fuel, it doesnt do any car much good. Link to comment Share on other sites More sharing options...
Ska Posted February 16, 2005 Author Report Share Posted February 16, 2005 If there isnt one on the 8 then why does it need reseting? I've learnt the lesson the hard way Link to comment Share on other sites More sharing options...
charlie61 Posted February 16, 2005 Report Share Posted February 16, 2005 The previous owner of my 8 had a fuel pump fitted by audi, total was £768 but this included a tow in as well Link to comment Share on other sites More sharing options...
matt5791 Posted February 16, 2005 Report Share Posted February 16, 2005 Fuel pump must be something available from other sources other than Audi - What it its location like, ie is it labour intensive to fit? Matt Link to comment Share on other sites More sharing options...
Botang Posted February 16, 2005 Report Share Posted February 16, 2005 Sorry ska, thats what happens when you dont proof read I dont know if the A8 has a fuel cut off switch or not, I was thinking out loud. If the chap gave the pump direct power and earth it looks like it may well be knackered. Link to comment Share on other sites More sharing options...
A8_Tony Posted February 16, 2005 Report Share Posted February 16, 2005 That's the only thing with these beauties. When they go wrong they cost you your first born to fix!!! Link to comment Share on other sites More sharing options...
Ska Posted February 17, 2005 Author Report Share Posted February 17, 2005 Its definatley the main pump. Question ive got for you guys is; is the feature about changing the seal on the sender unit on the tank in Audipages; is the sender unit and fuel pump the same unit if so how do you remove it? Also is the part number for a 1996 4.2q fuel pump the same as a 1997 ACK 2.8 sport? Parklands are chrging £811.31 Link to comment Share on other sites More sharing options...
cruiser647 Posted February 17, 2005 Report Share Posted February 17, 2005 Not sure on the part numbers, but will try to check it out tonight on ETKA. However, I think the 2 models mentioned have different shape fuel tanks (the 4.2 is a Quattro model, so the tank sits differently) Will get back to you on that. Oh, forgot to add - What a bunch of thieving ba5tards! Tell them to go stick it where the sun don't shine! Find an independent bod - a fuel sender should be the same sort of thing as a fuel sender in a Vauxhall/Ford or whatever - I would have thought!

PaulW Posted February 17, 2005 Report Share Posted February 17, 2005 The pump is a venturi system that is somewhat more complicated than a stanadrd pump, and I believe it comes with the whole plastic assembly surrrounding it. Make sure you get somebody who has a repair manual do the work because if they don't hook it up correctly, it will go dry at 1/3 tank. This is because the tank has two saddle tanks and it's common that they don't hook the far side one back up correctly and then it can't suck off it once the level goes low....there are actually two level sensors, one for each side if I remember and it averages it. Here's the internals.....this was for Luiz's twin turbo project, so the extra pump is shown, but it is mounted in this thing, which is part of what you get from Audi, BTW, it's about $900 here in the states.

Ska Posted February 21, 2005 Author Report Share Posted February 21, 2005 Paid £76 for Audi to diagnose the fuel pump problem: they said the fuel pump is knackered all connections etc were fine. This morning Dean at Allaudi phoned me up and told me that he'd removed the pump from my A8 and it was working fine?!? I've asked him to put the pump in from the 4.2 they're breaking and put my one in a box which I'll show the STEALER later on. Hope it starts after this...

Ska Posted February 21, 2005 Author Report Share Posted February 21, 2005 I'm not sure... hoping its tomorrow but Allaudi told me that the car isn't starting even with the pump from the 4.2 they had. So they are gonna look further into the problem. I may be clutching at straws but could the fuel filter be blocked? Who are the nearest Stealers to allaudi, Bristol? May just have to take it to them if Allaudi cant resolve it. Link to comment Share on other sites More sharing options...
