chrisw 0 Posted December 7, 2005 I ran out of petrol yesterday like a total idiot. No excuses, I was just completely daydreaming for about half and hour. Bad habit of mine. Once I left work to go somewhere and drove halfway home on autopilot before realising I should be going the other way. Anyway, now my Vr6 is running really rough. Idle problems & hesitant on the throttle. I am sure it sounds really rough as well, a bit raspy and boomy. I gather this is likely to be a fuel system problem. I have got a new filter which I will try later and some Redex, not sure about that stuff though. Failing that am I looking at the fuel pump? Any easy tests to try to isolate the problem? Seems like the rubbish in the bottom of your fuel tank theory must be correct. I've run out loads of times before in other cars (see above) and never had a problem, none quite as old as my rado though. Cheers Chris Quote Share this post Link to post Share on other sites

VR6 0 Posted December 7, 2005 I'm sure I remember reading something about it being very unlikely that it's down to 'rubbish' in the bottom of the tank .... forget why though.... Quote Share this post Link to post Share on other sites
Supercharged 2 Posted December 7, 2005 May have got some grit in the accumulator but chances are the new filter will sort it... Quote Share this post Link to post Share on other sites
dazzyvr6 0 Posted December 7, 2005 well the fuel is filtered at the refinery and at the petrol station,and the fact that the corrado petrol tank is plastic,so you shouldnt get any crud in your tank Quote Share this post Link to post Share on other sites
dr_mat 0 Posted December 7, 2005 Swap the filter anyway ... You may also have sucked some air up into the fuel lines, so you may just have to wait for that to blow out the system before it sorts itself out. Quote Share this post Link to post Share on other sites
Supercharged 2 Posted December 7, 2005 dazzyvr6, I know what your saying but there is still a huge amount of crud that makes it's way thru - next time you change your fuel filer try hacksawing it open - you'll be changing it at least once a year from that point on!!

Yandards 0 Posted December 8, 2005 It's actually a combination of fuel and water that causes the grief. Ahem, All cars will collect a certain amount of water in the fuel tank due to condensation etc. At the fuel/water layer a bacteria called Gladis (cladosporium resinae) and others thrive because they digest the hydrocarbons in the fuel. After a hearty meal they do what all organisms do - they take a great big crapola; this results in the 'crud' in your fuel tank. It is possible to add chemicals to the fuel to prevent this but it is ususally not 'environmentally sound' and would certainly make the fuel from the pumps very toxic to the general public. So the solution for car users is to fit a filter and get it changed every once in a while. Thats where the 'sludge' comes from and not the cut of the fuel in the tanks at the service station. Anyone still breathing? :wink: Quote Share this post Link to post Share on other sites

bristolbaron 11 Posted December 8, 2005 I had my fuel filter changed last month at gwerks. darren mentioned that the fuel filter was original.. i thought he just meant it was a VW one, but he meant it was original! with 13 years worth of very thick very black Gladis sh!te in it! it seems to run a whole lot better now btw!

Walesy 0 Posted December 8, 2005 Yeah, they are supposed to be a lifetime part, but I changed mine as soon as I bought each raddo as when I changed the first one (( 86k mile 8v )) I cut the old one open and the shcitt in there was unbelievable. For the sake of a few quid I can't see why VAG call it a " lifetime part " Quote Share this post Link to post Share on other sites
DEL VR6 0 Posted December 8, 2005 my first thought when i read the post was to change the fuel filter, and after reading what the others have said, it is still to change the fuel filter. Quote Share this post Link to post Share on other sites

chrisw 0 Posted December 8, 2005 I've given the car a good shakedown today (30 miles+) and it is much better w/ a new filter but still a little rough on idle. It was perfect before. I had problems when I first got the car but after a good service I haven't had a stall (that was the car's fault!) for 6 months or so. Any tests that can be done on the accumulator other than replacing it? If the fuel pump is quiet can this be assumed to be okay? Chris Quote Share this post Link to post Share on other sites
