indie Posted May 14, 2017 Report Share Posted May 14, 2017 Hello gang! OK so having some bother with my GTI This weekend, almost completely out of the blue, it started cutting out. Embarrassingly there was a really nice red (modified) Lupo coming up just behind me near junction 29 on the M25 - anti clockwise. Would have given a wave, but unfortunately ended up dealing this none sense! Overall my Loop is in pretty good nick. It's on 126k, but they are mostly motorway miles and it gets regularly serviced. What struck me as strange is that after a half hour on the hard shoulder it suddenly fired back up. Unfortunately my return journey was plagued with this issue, so it's not a one off. TBH I didn't enjoy driving it back, but had little choice on a Sunday. Following each cut out the starter turns it over fine, but the engine shudders and doesn't actually fire. I'd say there was something horribly wrong, but eventually it will start and run perfectly for tens of miles. I did 60 miles home today from my destination and it did this twice. I haven't run a diagnostic on it yet and have one of those cheap cables from eBay, but it's a bit of a faff. Would a basic hand held diagnostic work to dump any fault codes? (EML is not on BTW) A couple of years back it had a new fuel pump, so I'm guessing it's not a weak pump. Recently it had a new alternator and the batter seems perfectly fine. Other than that anything I should check? A blocked fuel filter seems possible because it cut out at the end of my street before parking, as if low fuel flow is causing the issue. I was simply tootling along in 6th when it cut the other times. Coil-pack, cam/crank sensors are all originals, so also possible. I'm a bit stumped really.

Rich Posted May 14, 2017 Report Share Posted May 14, 2017 I once had a golf mk3, kept cutting put and wouldn't restart for ten minutes at a time, that was the crank sensor, later I found out that once the oil reached a certain temp it was giving crappy readings.

indie Posted May 14, 2017 Author Report Share Posted May 14, 2017 Thanks for the reply. I guess it could be the crank sensor. Any idea of the location of this? My engine management light is on, which makes me think this is going to be a bugger to sort out. In the case of oil giving crappy readings, is that related somehow? On my old car the crank sensor was on the gearbox housing. Pretty sure it used to count the teeth on the flywheel as they went past. Quote Link to comment Share on other sites More sharing options...
indie Posted May 14, 2017 Author Report Share Posted May 14, 2017 Just ran VCDS lite on it. P0171 & P0321 were logged. What do you reckon? Reads like the crank sensor. I can't get much more info 1) because my cable came from eBay 2) I need a license. Quote Link to comment Share on other sites More sharing options...
Rich Posted May 15, 2017 Report Share Posted May 15, 2017 eBay cables aren't great but okay if you're not reading measuring blocks etc. sounds crankish, it is just on the front of these. if you're near me I have a working spare you may borrow.

indie Posted May 15, 2017 Author Report Share Posted May 15, 2017 Thanks for the offer Rich, thats very kind. Sadly I'm way down in Kent these days, so it'll be a bit far to pop round. Might give the crank sensor a go - they're probably not expensive. Front of the block? Read a few things about after market parts being total rubbish. You reckon its a VW/TPS job?

Rich Posted May 15, 2017 Report Share Posted May 15, 2017 vw don't make them and euro car parts will be liable to give you a seimens brand one which is what VW use. Quote Link to comment Share on other sites More sharing options...
indie Posted May 15, 2017 Author Report Share Posted May 15, 2017 Sweet thanks, I'll give it a whirl - not ready to give it up just yet. Daft sod fired up the moment the recovery truck arrived. The dude and his mate were like, ha thats bloody awesome - never seen one in real life. Should have sold him a cheap GTI. Quote Link to comment Share on other sites More sharing options...
Rich Posted May 15, 2017 Report Share Posted May 15, 2017 I'll buy a cheap gti. standard crank if it only stops working till it cools down. Quote Link to comment Share on other sites More sharing options...
indie Posted May 15, 2017 Author Report Share Posted May 15, 2017 (edited) haha. Yap, that's exactly the issue I'm having - cut's out, starts maybe a half hour later when it has cooled down a bit. Goes like stink until the next episode. ECP down may way reckon they have a Facet brand sensor. I expect that'll do the job - 45 squid.

indie Posted May 15, 2017 Author Report Share Posted May 15, 2017 I'm not happy about the supermarket culture that seems to be gathering. Used to work in a bike shop when I was a student. Folks would come in, get sized up, ride the bike and f*ck off to order it online Quote Link to comment Share on other sites More sharing options...

indie Posted May 15, 2017 Author Report Share Posted May 15, 2017 haha yeah, but that's different PS. Where is the bloody sensor? We're talking like down the front of the block somewhere? Cambelt or gearbox end? Quote Link to comment Share on other sites More sharing options...
Rich Posted May 15, 2017 Report Share Posted May 15, 2017 gearbox end, easy to spot. 5mm Allen key. Quote Link to comment Share on other sites More sharing options...
indie Posted May 15, 2017 Author Report Share Posted May 15, 2017 Thanks man. I'm guessing jack it up and feel around the back of the bell housing? Couldn't see it from the top like. One of my only grumbles with the Loop is the lack of Haynes book. I bought some stupid download a while ago, but it was a massive pain to use.

Rich Posted May 16, 2017 Report Share Posted May 16, 2017 I'm wrong, it is on the back and looks a pig to get at. fortunately I have an engine on the floor I can look at. Quote Link to comment Share on other sites More sharing options...
