nayr Posted August 10, 2010 Report Share Posted August 10, 2010 Last night something caught on a speedbump underneathe the car then about 10 minutes later the car cut out at traffic lights.All the electrics worked but the car wouldnt turn over!Im guessing ive ran too low and ****ed something to do with the alternator wiring/earthing points?Are these easy to fix by myself or not?Any help is appreciated!

northwick Posted August 10, 2010 Report Share Posted August 10, 2010 You still got fuel? i.e. have you knocked a fuel line and have now run out because its all over the road? Quote Link to comment Share on other sites More sharing options...

Pete Posted August 10, 2010 Report Share Posted August 10, 2010 Have a good check underneath mate if you haven't done so already, if its gone with a biiiiiig bang then the lupo may have like an inertia switch as a safety feature which basically thinks that if you've had a big bang or possibly even rolled it, it cuts all fuel and igntion sources to stop the car blowing up essentially. With the igntion on can you hear your fuel pump running?? Thats usually a good indication, if it is then it may just be summat simple.

nayr Posted August 10, 2010 Author Report Share Posted August 10, 2010 fuels fine, cleaned out throttle body,checked all connections plugs and fuses but still wont turn over Possible alternator death? Quote Link to comment Share on other sites More sharing options...
Pete Posted August 10, 2010 Report Share Posted August 10, 2010 Its more likely to be a starter fault mate I'd say if its not cranking at all, check your battery voltage out tho. It seems abit weird for the battery to go flat so quick. Quote Link to comment Share on other sites More sharing options...
treblet Posted August 10, 2010 Report Share Posted August 10, 2010 The car wouldn't cut out if your alternator had gone, it would just stop charging your battery.And if all the electrics still work I'd suggest your battery is still okay.Have you checked the wiring which goes round the bottom of the sump and runs close to the O/S drive shaft?

Silver! Posted August 10, 2010 Report Share Posted August 10, 2010 The car wouldn't cut out if your alternator had gone, it would just stop charging your battery.Sorry Jamie, but wait 'til Claire's alternator goes and you may change your mind on that. My GTI started and ran for about 10mins before all hell broke loose with the electrics\dash lights and then the engine cut out.I was convinced it was worse than the alternator 'cause I thought similar to yourself.

treblet Posted August 10, 2010 Report Share Posted August 10, 2010 Her's has gone already Ray!All that happened is the car wouldn't start, no dramatics at all.Generally speaking the engine should continue to run on without the altenator, mind you judging by the way VW wired the Lupo anything could happen if you lose the altenator!!

Silver! Posted August 10, 2010 Report Share Posted August 10, 2010 The next day mine started from a battery with just enough jiuce to turn it over ran fine and then coughed and died 15min's later.Although still expensive, I was happy when it was just the alternator.

Bigfoot Posted August 11, 2010 Report Share Posted August 11, 2010 The alternator belt still there? A stray shoe broke mine into alot of little bits not too long ago and the car wasn't too chuffed with there being no charge going to the battery.Easiest way to check if your belt is still in tact is that there will be no power steering as it is driven off the same belt.But try jump start the car first with jump leads Quote Link to comment Share on other sites More sharing options...
nayr Posted August 11, 2010 Author Report Share Posted August 11, 2010 Had a mechanic look at it today and he's told me its the crankshaft sensor which he's going to replace.He said this might make a fault that will need clearing.Can I clear a fault myself by disconnecting the battery or anything?Cheers.

mat.m. Posted August 14, 2010 Report Share Posted August 14, 2010 (edited) Finding a nice engine will be the hardest part.When was the belt last changed? Edited August 14, 2010 by mat.m. Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted August 14, 2010 Report Share Posted August 14, 2010 If you take the front off, an engine change to the same engine code is pretty easy tbh. Just unplug it all, disconnect exhaust, driveshafts and gear cables and it will come straight out of the front.Hope you can find one soon!John Quote Link to comment Share on other sites More sharing options...
