my gti has been cutting out again this week i had this problem in sept time and changed crank sensor and relays 30 and 167.this morning bought a coil fitted this with no change what so ever.wednesday nite checked coil by putting spark plug in lead when engine was cold/cool it would spark but when teperature gauge is around half way line this is when it cuts out and no spark is coming from coil cleaned the thottlebodie out with carb cleaner and toothbrush still no change what so ever.itwill idle for around 10mins ish on drive then cut out and when driving it gets to that half way line and get to junction or roundabout go to slow down and thats it cuts out wont start again till it cools down.any ideas would be great
cheers

Hmmmm I had this problem with my ady golf and sorted it by changing the temp sensor as this control's the gauge and ecu...... cost about a tenner..
not sure about no spark tho.
-
which temperature sensor and where to is it please
cheers 4 your help
-
it's the one that work's the gauge and also send's a signal to the ecu....If i remember correct it's at the front of the engine (and it just pushes into a pipe at the top)and blue coloured with 4 wire's to it..If you can't find it i will try and take a picture tommorrow of mine and show you???

update my missus went to get me fuel pump relay and ecu relay from vw just got back from work to find that the idiots had given her fuel pump relay and temp sensor instead.so i put relay in and thought give the sensor a go b4 i take it back 2moro. idled for 15mins then cut out again at 64 degrees on computer.wont re-start one thing i noticed was no.30 relay was very warm but all other relays were cold
-
Relay 30 is the ecu relay...sound's guilty to me
It's also worth checking this post http://www.golfgtiforum.co.uk/index.php?topic=2080.220 (http://www.golfgtiforum.co.uk/index.php?topic=2080.220) and I've just added a few common problem's these engine's have

Here's the common mk3 dying problem's
1 dirty throttle body
2 faulty ecu relay no 30
3 faulty fuel pump relay no167
4 hall sender
5 Crank angle sensor/engine speed sensor
6 ecu temp sensor
7 coil pack
Could be a good time for a fault code reading and see what pop's up...you can but the reader's on ebay for about £35

I know this sounds obvious, check for holes in the breathers etc - specially that dam rubber piece of crap,
the spark problem is a puddler...
pain in the ass, fred flintstone had the right idea, cut some feet holes and run

tried starting it last nite no go battery started to die so put spare 1 on charge over nite.just went changed batterys over still no go checked spark from the coil and nothing at all. i am no mechanic so any ideas why/or what could be shutting coil down.its a new coil less than week old
any help would be great
-
been looking at car again today swapped and changed coil/batterys still no go.no spark coming from coil checked plugs doesnt look like petrol coming through either plugs dry.could there be a problem with alarm/immobiser its a meta cat 1 m999t i think that shuts off fuel pump and coil as part of security
