LincolnLupo Posted March 31, 2005 Report Share Posted March 31, 2005 I'm not exactly an expert when it comes to engine related stuff but I need someone to confirm if there is only one cat for the Lupo Sport? :oops: Volkswagen Lincoln say they changed the cat for me when they did some work on the car just after I bought it (about 10 months ago) and it's only done about 3000 miles since.I took it for a MOT a couple of days ago and the emissions are over what it should be so they think the cat's gone.Just want to make sure the one that's failed is the one they changed.

Tigz™ Posted March 31, 2005 Report Share Posted March 31, 2005 You have your main CAT and your `Pre-CAT`.I wouldnt think a faulty `pre-CAT` could cause your problems, so if it was me Id be knocking on the door of VW. Quote Link to comment Share on other sites More sharing options...
Red Lup Gti Posted March 31, 2005 Report Share Posted March 31, 2005 Might be a tps sensor (throttle posision sensor) or a air flow sensor mate!! Get it on vag.com! Quote Link to comment Share on other sites More sharing options...
LincolnLupo Posted March 31, 2005 Author Report Share Posted March 31, 2005 Is that likely??I'll get the results up when I get home but it was massively over.From memory I think the CO value could be a max of 0.3 and I was getting about 7.2 (both runs)the other reading was over as well.I only just had the car on vag.com yesterday (ABS warning light - n/s/f abs speed sensor gone). Would they have only looked at the brakes within vag.com or would they have seen other faults pop up? Would have expected them to tell me if they'd seen anything else wrong??

paulbin Posted March 31, 2005 Report Share Posted March 31, 2005 sounds like its stuck on choke, as ross said air flow sensor. Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted March 31, 2005 Report Share Posted March 31, 2005 But wouldnt that have shown up on the Laptop yesterday? Quote Link to comment Share on other sites More sharing options...
paulbin Posted March 31, 2005 Report Share Posted March 31, 2005 Vag is split up into different sections i think, so u have to choose wot u want to view Quote Link to comment Share on other sites More sharing options...
LincolnLupo Posted March 31, 2005 Author Report Share Posted March 31, 2005 OK here's the results given...Fast Idle testengine speed 2611rpmco level 7.19% (max 0.30)hc level 259ppm (max 200)lamba 0.81 (min 0.97 max 1.03)Fast idle test 2engine speed 2586rpmco level 7.17%hc level 281ppmlamba 0.80Natural idle test 839rpm (min 790 max 940)co level 5.99 (max 0.50)Overall FAILDoes this still sound like a sensor problem??Can't afford to keep wasting my money on vag.com diagnostic charges. The ABS sensor problem's going to set me back £140 already.I'm trying to sell the car and this is all dead money. Quote Link to comment Share on other sites More sharing options...
Red Lup Gti Posted March 31, 2005 Report Share Posted March 31, 2005 yep, put money on it being a sensor problem mate!! 5.99!!!! bloomin' hell Quote Link to comment Share on other sites More sharing options...
LincolnLupo Posted March 31, 2005 Author Report Share Posted March 31, 2005 loldon't care if it's £5.99more bothered about cr@p from VW when they say "hmmmm well it's difficult to get to... how about we charge you 3 hours of labour and an hour diagnostic charge" or something equally stupidIs this cheap and easy to replace then?The MOT place I took it to (local AA approved centre) seemed to think the lamba sensor had gone (see test results) and quoted about £90 for itSeem reasonable or are they trying to screw me more than usual?Just want to get rid of this one now and get the gti (hopefullty on sat) Quote Link to comment Share on other sites More sharing options...
Adam Posted March 31, 2005 Report Share Posted March 31, 2005 i think he means the level is 5.99 where as the max is only 0.50, so its quite a way over. if you have only done 3000 miles and it is quite a bit over the maximum i would have thought its probably a sensor. i had a sensor go on mine and it had only done 3500 miles. It was causing the choke to work at the wrong times and this was overfuelling. Quote Link to comment Share on other sites More sharing options...
LincolnLupo Posted April 1, 2005 Author Report Share Posted April 1, 2005 lolthat's what happens when you read info while talking to parents, all kinds of misunderstandings arrise!yep, I wasn't overly impressed either with that idle figure and yes it does seem to use a bit more fuel than it should.do you know if your overfuelling problem produced similar results?how long did it take vw to fix? am I looking at a hefty bill or a manageable one?I'd appreciate experiences / details from anyone who's had similar problems.

Adam Posted April 1, 2005 Report Share Posted April 1, 2005 Is there an orange light on, on your dash? with "CHECK" wrote underneath it? As this was the first reason why i wanted to take it to them as mine was on from day 1 after i bought it (3.5k miles) my car then started to become very jolty in the mornings and they told me this was because the auto choke came out straight away as the sensors were saying the car was warm already, this caused the overfuelling. im not sure about my emissions as i never seen a print out for it. there is a pic somewhere on the forum of the graph they gave me after they sorted it. it shows there were two damaged sensors, one in the manifold and one in the cat. just get them to plug it into there computers and check for sensor problems.it took me two visits two VW, the first time i think they just reset the sensors etc on the car not thinking properly, this did remove the light from the dash, but only for 30 miles or so. The second time i left it with them for 2days and they changed the sensors on the car (the broken ones) and checked the engine/exhaust for any niggles and did about 80 odd miles on my car to make sure it didnt come back on. since then the light has stayed off, my fuel consumption is round about average i think (`220-250` miles to the tank) and ive done about 4k miles and everything is fine (touch wood!)As for the cost, im not sure as i had all mine done under warranty, hopefully yours still is under warranty.Sorry to babble on, but i hope that gives you a better indication of what happened to mine.
