P38Aaron 0 Posted June 21, 2004 Hello, new to all this, Got a Corrado VR6 some months ago had huge misfire at high-ish revs 3500rpm went into VW and diagnosed as speed sensor pickup, few months later same sort of thing speed sensor sender caused but damaged front engine mount, both quite expensive jobs. car back now no misfire all good! but...now car is ticking over very low 300rpm or so, occasionally as i pull up to traffic lights sometimes stalls out. also when in slow moving traffic car stalls a few times then the revs start to search all over the place and is generally a pig to drive, am not wanting to put it back to VW as is getting expensive and I would like to learn something about my engine. Have read in previous mailings about ISV. How would i find this and do what to it? would this have any part in my poor little C not feeling too well? Also is there anyway of picking the revs up? Thanks for your time Aaron Quote Share this post Link to post Share on other sites
vr6storm 0 Posted June 21, 2004 best get someone to hook it up to VAG-COM as by the sounds of it you've got a duff sensor somewhere........if you don't know anyone near you with VAG-COM then you'll have to bite the bullet and get it in a garage so equipped or back to VW Quote Share this post Link to post Share on other sites
dr_mat 0 Posted June 21, 2004 I'd be surprised if it'll maintain 300rpm without stalling.. Stalling is a common feature of the VR6 engine, it's a result of the ECU being over-frugal with fuelling is the speculation at the moment. It has been known to be fixed by: o) engine speed sensor replacement (they *did* torque the new one to the correct settings, didn't they??) o) injector problems o) fuel pump o) MAF problems o) ISV problems o) fuse/relay (dunno which one) o) any one of a dozen other, non-related things!! If it didn't stall before the engine speed sensor and now it DOES they should double check the mounting of the sensor (it has to be installed a certain way). Also, when removing/refitting the front engine mount, there's a load of cables to the front bank's knock sensor that have to be cleanly reconnected (not to mention a row of temperature sensors that have to be reconnected). Any of these cables badly damaged or just plain not reconnected will cause unknown problems with the engine's running. Quote Share this post Link to post Share on other sites

dr_mat 0 Posted June 21, 2004 I would suggest you find a local VW specialist, I can't imagine how badly VW are NOT interested in looking after your Corrado. They just don't see cars this old any more, and they have little or no experience of working on them either. Sure they have the manuals, but so do local specialists, and then they have actual experience of working on older VWs too. Not to mention the fact that they are going to charge you about 50% of the VW hourly... There must be some folks on here that can point you to some specialists around the cambridge/essex area? (BTW - while you have warranty on the work that's already been done by VW maybe it *is* worth going back to them, but ONLY if they're working on this as warranty, not if it's new work..)
