fla 9 Posted April 9, 2007 Old thread here BUT, i'm having just this problem right now and VAG COM is not throwing anything up at all. MPG used to be 31-34 on a good run at 70-85 mph. But this last weekend we did a 400 mile round trip 90% motorway driving and no traffic and the best i got was 27.5 and it just refused to go any higher despite dropping to 60 in places. Any suggestions? Quote Share this post Link to post Share on other sites

fla 9 Posted April 11, 2007 How can you test the lambda directly, with a multimeter perhaps? Quote Share this post Link to post Share on other sites
latestarter2 0 Posted April 12, 2007 Yeah the down pipe flexi-hose is a common one... you know when it's gone when you get exhaust/petrol smells first thing in the morning which goes when hot as the joint expands. £120 from VW is as bad as I thought (mine's gone by the way), but it's still not cheap :( aah..that might explain why I'm get a very strong fuel smell when starting up in the morning!! My fuel consumption isnt bad tho 30-32 on a long run and about 28 round town. Would the split pipe affect the starting when the engine is hot too?

latestarter2 0 Posted April 12, 2007 cant this be repaired rather than replaced with cloth tape or exhaust repair stuff?

antonio_b12 0 Posted April 17, 2007 After cleaning my lamba probe with brake cleaner... i've been getting an average of 32-37mpg on the old motorways, 5th gear 2-3000 revs... worth a try cleaning before getting an new lamba... Quote Share this post Link to post Share on other sites
fla 9 Posted April 17, 2007 good call antonio_b12, will try that and see what happens. VAG COM doesnt tell me anything at the moment. Quote Share this post Link to post Share on other sites
