vondally Posted June 7, 2014 Report Share Posted June 7, 2014 Hello first post but long time reader. I own a 02 1.4TDI, I bought it 25 months ago with 35,000 miles on it FSH, now 81,000 miles FSH due to 70 mile daily commute on A roads and Motorway. Having owned lots of Golf Gtis I have to say this is one of the best cars I have owned.....so the problem and this has occurred 6 times in 25 monthsdriving along approaching a roundabout or junction, decelerating and the engine cuts out...all power goes battery lights come on (probably all the others) and then I restart the engine it cranks over but does not catch, sounds like the engine is trying to start but seems no fuel is getting in judders and the after anything from20 seconds to a minute starts up and kicks into life.Taken it to garages and they have replaced fuel filters and found nothing wrong with it. Just had the fuel relay switch replaced after an internet search BUT the car has cut out again at a junction.So can anyone offer a solution?or aReputable Knowledgeable Garage NW England? Taken to two locals one after VW Franchise told me car was too old to look at! Both local ones are good but this seems to be a specialist incidentReally love the car but I am worried it will cut out on the motorway BUT to date it is only on deceleration at roundabouts and junctions.Also would a remap help?All Help thoughts and ideas welcome!

Dblock Posted June 7, 2014 Report Share Posted June 7, 2014 Have you changed that relay 109 or crank sensor? Before it cuts out does it do anything like become sluggish or make any noise? Also it's 100% not overheating is it? Quote Link to comment Share on other sites More sharing options...
vondally Posted June 7, 2014 Author Report Share Posted June 7, 2014 relay changedsluggish not really, power drops within 50 feet of roundabout, noise no100% not overheating new sensor fitted 6 months ago..............also no signs of overheatingthanks for ther eply Quote Link to comment Share on other sites More sharing options...
jon_273 Posted June 7, 2014 Report Share Posted June 7, 2014 It needs scanning with VCDS for fault codes really. One thing that springs to mind is that the crankshaft position sensor might be on it's way out - this is used by the ECU to tell it when to inject fuel, when it starts to fail it gives false information so the ECU tries to inject at the wrong time and the car won't run. If it's faulty you can just unplug it and still use the car as the ECU will use the signal from the crankshaft position sensor instead. Just means it will take longer to start.However this does not explain why it only happens when decelerating. Quote Link to comment Share on other sites More sharing options...
vondally Posted June 7, 2014 Author Report Share Posted June 7, 2014 thanks been scanned twice no faults.....apparently.So struggling with finding a cause Quote Link to comment Share on other sites More sharing options...
Skezza Posted June 7, 2014 Report Share Posted June 7, 2014 Stop solenoid perhaps? Quote Link to comment Share on other sites More sharing options...
jonny s Posted June 8, 2014 Report Share Posted June 8, 2014 possible crankshaft sensor?? does other struggle to fire ever? Quote Link to comment Share on other sites More sharing options...
Dblock Posted June 8, 2014 Report Share Posted June 8, 2014 I doubt it and it is highly unlikely that the asv is broken and the flap closes but then reopens after a bit? But I stick to my first guess and say crank sensor. Quote Link to comment Share on other sites More sharing options...
