sapphire1616 Posted November 21, 2006 Report Share Posted November 21, 2006 Got a 2002 S8. Pulled into fuel station to fill up at the credit card pump. Jumped out and went to use and saw a notice that pump was faulty. Cursing etc. jumped back into the car and tried to start to move to another pump and the engine fired, ran for a couple of seconds, then stopped. Tried it 4/5 times and it did the same thing. So sat for 15 seconds with it switched off. It then fired up ok with no problems since. Did I just confuse the management system, or what? Link to comment Share on other sites More sharing options...
edo Posted November 21, 2006 Report Share Posted November 21, 2006 possibly some sort of flooding? Link to comment Share on other sites More sharing options...
Ska Posted November 21, 2006 Report Share Posted November 21, 2006 Its proly the immobilser black wire that needs sorting. Does the yellow immobiliser light flash when it you try to fire it up? Simple fix if it is Link to comment Share on other sites More sharing options...
sapphire1616 Posted November 21, 2006 Author Report Share Posted November 21, 2006 Thanks for the replies. I can't say I noticed the immobiliser light. Where is it? Shows how much notice I took of it eh!Just kept trying to start it until it did! Link to comment Share on other sites More sharing options...
Ska Posted November 21, 2006 Report Share Posted November 21, 2006 Its on the dash where the battery and oil pressure light is. Have you got your steering retract feature on? if so that doesn't help the wire gets snagged. All you have to do is clean up the wire and contact leading to the ignition barrel then put some more insulation on it by way heat shrink sleaving and your away Check this thread out from a while ago Link to comment Share on other sites More sharing options...
sapphire1616 Posted November 22, 2006 Author Report Share Posted November 22, 2006 Thanks for this Ska. Really helpful. I will check this out now. Link to comment Share on other sites More sharing options...
sapphire1616 Posted November 22, 2006 Author Report Share Posted November 22, 2006 Sorry. Being a bit useless in car departments now but how difficult is it to get the covers off to get at the black wire? Any advice, including choice of 'crow bar' to use most welcome!

Ska Posted November 22, 2006 Report Share Posted November 22, 2006 IIRC you have to remove the steering wheel to get access to the steering column screws . Not too difficult if I recall corectly just make sure you disconnect the battery before removing anything from the steering or you'll risk setting off the airbag. I'll dig out the work shop manual proceedure tonight if you want? Link to comment Share on other sites More sharing options...
sapphire1616 Posted November 23, 2006 Author Report Share Posted November 23, 2006 Thanks Ska but I think you have just found the limit of my capabilities. I do not fancy taking the steering wheel off whilst clenching my buttocks tightly. I will leave that to those more used to it. Thanks for your guidance though. I now know what I must get done.

sapphire1616 Posted November 30, 2006 Author Report Share Posted November 30, 2006 Sorry to keep going on about the problem but as yet I haven't had opportunity to get the black lead sorted. What I have now noticed is that when I start the car from cold it fires, then momentarily dips in revs and then picks up straight away to tick over as per normal. Does not do it when warm....all is fine then. Could this be related, or part of the same problem? Link to comment Share on other sites More sharing options...
Ska Posted November 30, 2006 Report Share Posted November 30, 2006 That might be a throttle body/ISV syptom. I normally clean those out with carb/injector cleaner as a matter of regular maintanence with lint free cloth. If it the Immobi then it switches the car off and the light may light up Link to comment Share on other sites More sharing options...
sapphire1616 Posted December 10, 2006 Author Report Share Posted December 10, 2006 Thanks for the info Ska. I am not familiar with the under bonnet area of the S8 so could you, or anyone else, advise as to how I get to said throttle body. and what is needed to be taken off to achieve a clean up. I have done it before on other vehicles but never ventured into the 'under engine cover' area of my S8. If there are any particular difficulties I may meet then to be prepared is helpful. Thanks.
