indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 (edited) haha, yep just been out to have a look... spent some time looking at the front of the gearbox scratching me head Seems like its an M6 bolt head and faces sort of down on rear/top section of the box. Contrary to the pictures I've seen of the part, it looks like the wiring loom reaches out and plugs into the sensor, not a sensor with a loom included ... if you know what I mean? Didn't have time to remove it yet. Lot's of sh*t in the way. Have you got a picture of yours by any chance? Doesn't help my VIN doesn't appear to work on various sites for finding the part.

indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 haha um, I can't make it out from that pic. The thing I'm talking about can be just about seen when you're standing looking down at the top of the box. Quote Link to comment Share on other sites More sharing options...
cj1 Posted May 16, 2017 Report Share Posted May 16, 2017 15 hours ago, indie said: 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. at the back. May be easier with starter off too.

indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 Thanks for helping. In this link I think there is a picture of a 6 speed box off the car. The part that I think we're talking about it directly below the throttle, or above where the drive shafts would normally go. Feels like a 6mm allen, but lots of linkage/clutch cable/hydraulic none sense in the way. I could have sworn the starter is at the front on mine... https://www.clubpolo.co.uk/forums/topic/328392-lupo-gti-block-and-gearbox-in-mk2/?page=2 Quote Link to comment Share on other sites More sharing options...
Rich Posted May 16, 2017 Report Share Posted May 16, 2017 the starter is at the front, the crank sensor is at the back, you can see the plastic plug cover at the back. Quote Link to comment Share on other sites More sharing options...
Rich Posted May 16, 2017 Report Share Posted May 16, 2017 I've shown the cup so you get perspective. I would remove the inlet manifold to do this, but you could use a mirror if you're clever and have skinny arms. Quote Link to comment Share on other sites More sharing options...
indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 hehe thanks Rich. The cheeky lovely persons - why did they put it there. haha. What I like best about repairing my car in the street... a bit of public engine shagging. Tenner says I take 90% of the f*cking thing apart to get in there :-) PS. I had a 106 gti before this... nothing can be as bad as that! Quote Link to comment Share on other sites More sharing options...
Rich Posted May 16, 2017 Report Share Posted May 16, 2017 there's going to be some fun had there. I wouldn't mind that as a job though. Quote Link to comment Share on other sites More sharing options...
indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 Oh my f*cking word... That was horrific. I can't see anybody getting that out without removing things. If you've done it before you might if the car was on a ramp, but I think you'd need a mirror. Inlet off. Fuel rail. Throttle body. Only then did I realise you meant this little sucker... It was behind a rubber bung, which I could feel with my hands, but couldn't really make out. On the plus no corrosion thanks to the rubber thing. For anybody else that reads this the sensor appears to hold the bolt captive, so a little less worry once it's loose.. not exactly likely to drop back inside the gearbox (they at least thought that through). I need a stiff drink and to order a new sensor. Quote Link to comment Share on other sites More sharing options...
indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 Now to choose a brand for the sensor. I can have Facet, Bosch, Delphi, Vemo or Metzger. All vary massively in price. lol Quote Link to comment Share on other sites More sharing options...
Rich Posted May 16, 2017 Report Share Posted May 16, 2017 Bosch? Quote Link to comment Share on other sites More sharing options...
indie Posted May 16, 2017 Author Report Share Posted May 16, 2017 Yeah man, I agree. Really *don't* want to take this apart again in a hurry. Quote Link to comment Share on other sites More sharing options...
indie Posted May 20, 2017 Author Report Share Posted May 20, 2017 (edited) Bit of an update. Changed the sensor, but then it wouldn't start! Put back the old one, but same situation.. turns but won't start. Got power, spark and fuel. All checked. Not a fuse. Alternator was new 6 months back. Battery is ok, checked with a multi meter. Had a cuppa, scratched my head and it finally fires up with the spare key, now it's fine on both keys! Any idea guys? Would this be anything to do with the ignition switch? I've heard they can go a bit weird and cause cutting out and starting issues. Edited May 20, 2017 by indie Quote Link to comment Share on other sites More sharing options...
indie Posted May 20, 2017 Author Report Share Posted May 20, 2017 (edited) Nope. Cut out after 9 miles. Hmmm. Still throwing this up... Edited May 20, 2017 by indie Quote Link to comment Share on other sites More sharing options...

Mattymdm Posted May 21, 2017 Report Share Posted May 21, 2017 Which make sensor did you buy? Logged the same fault i can see P0321. If you've fit a sensor you'll have to go down checking the wiring route Quote Link to comment Share on other sites More sharing options...
indie Posted May 21, 2017 Author Report Share Posted May 21, 2017 Well against my and everybody else's guidance I ended up with a Facet unit. I didn't know this until I went to collect. TPS in my area didn't have one for a couple of days. ECP said Bosch, but when I turned up it was Facet... I didn't have the energy to argue. Sensor seems to function the same as the other though. There is no visible damage to the loom. I read the G28 error code can mean many things, not always caused by the crank sensor itself being faulty... At this point I'm considering a trip to VW. I'd say somebody familiar with interpreting the live data is needed. Car has new ignition leads, alternator, new fuel pump (well two years ago). I kinda expect the coil pack or fuel pump (again). My 106 gti use to do an almost indentical thing - cut out and refuse to start. That was a dicky pump, which was really hard to pin point because most of the time it was fine. So yup, either a trip to VW, or it's scrap. Lol. Quote Link to comment Share on other sites More sharing options...
Mattymdm Posted May 21, 2017 Report Share Posted May 21, 2017 The loom may look OK but you could still have a wiring issue. Or the Engine ECU can no longer read the signal from the G28. Don't loose hope though it can be fixed. Had a 106 Gti myself. Such a nightmare car aswell the lupo is in a different league. Quote Link to comment Share on other sites More sharing options...
indie Posted May 21, 2017 Author Report Share Posted May 21, 2017 Yeah the 106 had like two engines, three gearboxes and a beam rebuild. Handling was better and I think the JP4 conversion made it quicker, but I much prefer my loop. The maddening thing about the issue is that it'll do 20-30 miles fine, then die and refuse to start for an hour, or so. It really seems temperature related. I guess the loom could be damaged and it only causes an issue every so often. I think it'll be a nightmare to trace though. Quote Link to comment Share on other sites More sharing options...
Rich Posted May 21, 2017 Report Share Posted May 21, 2017 pin to pin, multimeter on continuity. no connection, add a magic wire external to the loom. I can post you my spare if you want to give it a go? Quote Link to comment Share on other sites More sharing options...
Rich Posted May 21, 2017 Report Share Posted May 21, 2017 can't trust Ecp not to give you one for a 1.4 either. We need lupogtiboy to tell us if they are specific. Quote Link to comment Share on other sites More sharing options...

indie Posted May 22, 2017 Author Report Share Posted May 22, 2017 Thanks Rich, appreciate the offer. I admitted defeat and have booked it in at VW. The main dealer in my area is pretty good in my area. They've had the car in for various bits in the past. I will post back! Quote Link to comment Share on other sites More sharing options...
