julesm 0 Posted May 17, 2004 Report Share Posted May 17, 2004 Finally got my car on VAG-COM at VW to try and find my stalling problem. The fault displays , has anyone come across this fault reading on VAG-COM before ????? I have been advised to get rid of the induction kit and go back to the standard box. Failing that it could well be back to the MAF as I have cleaned the thottle body, ISV and checked for vacuum leaks as advised. Can anyone suggest where I can pick up a MAF that would be cheaper than VW. I aslo spoke to a geezer called Ben (I think) at Inters on the Saturday at the club stand with a similar problem - hope this might help him and if he catches this thread, have you got any where with this f*****g stalling lark ?jules &| Link to post Share on other sites
julesm 0 Posted May 17, 2004 Author Report Share Posted May 17, 2004 S*** forgor to include the VAG-COM Fault (o2 sensor exceeding limit)jules Link to post Share on other sites
mightyvr6 0 Posted May 17, 2004 Report Share Posted May 17, 2004 Could be running too rich if the o2 is knackered. Cheapest maf is an exchange one from a bosch dealer £150+vat. Better than £350 from the dealer. Link to post Share on other sites

jcorallo 0 Posted May 18, 2004 Report Share Posted May 18, 2004 obd1 or obd2?also, you need to post the exact numbers and words that vag-com put on screen to be able to start to daignose the problem.oh - and I'm Jules! Link to post Share on other sites
jcorallo 0 Posted May 18, 2004 Report Share Posted May 18, 2004 If its obd1, go to the measurement blocks section in vag-com and go up until you get to the fuel trim data. Post up what values it has for the idle, part throttle and full throttle adaptation. Dont forget the exact fault code message also...!Jules Link to post Share on other sites
julesm 0 Posted May 18, 2004 Author Report Share Posted May 18, 2004 Its an OB1 and word for word the printout on my sales document said"checked for stalling, checked all connection to sensors and checked engine electrics with 5051, reset all fault codes (5 in total) rosd tested, only one fault still in the memory (o2 sensoe exceeding limit)"I'm glad to see you got yours sorted Ben, I wish mine had been cured so simply !!!! I forgot to clean that little box, I think its the silencer, was it easy to do ? Standard air box is going in next week anyway so I'll take it from there I suppose once its been on VAG-COM again.jules Link to post Share on other sites

FishWick 21 Posted May 19, 2004 Report Share Posted May 19, 2004 You might have an air leak upstream of the 02 sensor. Have a listen to the engine around the back and see if you can hear any exhaust blowing noises.You can check the O2 sensor with a high impedance multimeter. On the rear engine mount there is two connectors. The longer of the two is the 02 plug. Prod the meter's red lead into the white wire and rest the meter's black lead on the engine somewhere for ground. You need to do this when the engine is hot as the 02 sensor doesn't work until the pre-heater has done it's job, that usually takes 2 minutes. Don't burn your arms on the exhaust downpipe What you're looking for is a rapidly fluctuating voltage. The meter won't be able to keep up with the changes but ignore that, just look for an average high and low values of 0.1 to 0.8V. If the reading sits solid at 0.45V. The 02 probe is dead. £70 thank you very much, plus fitting.K[ Edited Wed May 19 2004, 08:25PM ] Link to post Share on other sites
VRmonster 1 Posted May 19, 2004 Report Share Posted May 19, 2004 hey, thanks for that kev, i noticed mine has an airy kinda noise near the downpipe. ill have to check its not blowing. Link to post Share on other sites
FishWick 21 Posted May 19, 2004 Report Share Posted May 19, 2004 Yeah do check that out as the ECU will think the engine is running lean and over compensate with the fuelling. Good excuse to put a cat-bypas on whilst you're down there ! Link to post Share on other sites
julesm 0 Posted May 19, 2004 Author Report Share Posted May 19, 2004 Do you think VW will carry out the test Kev has suggested if I print out the details, as they are fitting the standard air box for me next week? I haven't really used VW too much and know some places don't like to be given advice !! Plus I have very little faith on garages in gereral anyway !jules Link to post Share on other sites
