craiggolfmkII Posted March 28, 2004 Report Share Posted March 28, 2004 I have a 1990 Golf GTi 8v engine code PB. Just recently it has been cutting out whilst driving normally. The power just goes away and no lights on the dash. When the clutch is depressed the rev's fall off and the ignition light's come on and the cars coasts to a stop. <font color="blue"> </font> <font color="blue"> </font> The car fails to start straight away but if after 30-60 seconds passes the car starts fine and runs ok for between 1 and 2 hours. This fault has happened 4 times always on long journeys and at different speeds. It has gone as long as 2.5 hours without happening and as little as 50 minutes before showing up again. I haves changed the distributor cap, rotor arm, spark plug's and coil but no joy??? Been to VW and they don't know.... Can anyone please help Link to comment Share on other sites More sharing options...
ARKI Posted March 29, 2004 Report Share Posted March 29, 2004 ive seen this fault on a lot of golfs, and i think you will find if you change the ecu relay ( black with a 53 on it)to a new relay from vw that is white, 53. your problems will be over, the fault is that when the relay is in use it cant dissapate the heat and open circuts. then cools enough to opp and the car goes again.hence the color change of the relay. good luck..

craiggolfmkII Posted March 29, 2004 Author Report Share Posted March 29, 2004 Thanks ARKI. Cannot find the relay you are talking about, have searched the manufacturers book and cannot find it??? I have two white relays with 53 on them in my fuse box, pulled them both with the engine running and no joy??? Please help more... Link to comment Share on other sites More sharing options...
twc Posted March 29, 2004 Report Share Posted March 29, 2004 Hi, I had a similar problem with my 87' gti ages ago, It was a dodgey connection to the fuel pump. Link to comment Share on other sites More sharing options...
shao_khan Posted March 30, 2004 Report Share Posted March 30, 2004 I had this on a car when the earth strap had broken from the engine to the body work - would cut out and then be fine. Link to comment Share on other sites More sharing options...
craiggolfmkII Posted March 31, 2004 Author Report Share Posted March 31, 2004 Thanks twc, checked all the connections to the fuel pump and ignition systems... Still the same. Anyone else any ideas??? Also redone the earth connection's when the coil was changed... Thanks anyway... Link to comment Share on other sites More sharing options...
Tobes49 Posted April 18, 2004 Report Share Posted April 18, 2004 Have you changed the amp unit for the igniton system?? It sits on top of the ecu under the skuttle pannel. Otherwise when it stop you must test to see if you losing your spark or fuel. that will help narrow it down. Link to comment Share on other sites More sharing options...
craiggolfmkII Posted April 19, 2004 Author Report Share Posted April 19, 2004 Is that the one with the multipin connector called the 'ignition switch' sat on top of the silver heatsink type thing???? Have cheched the voltages to it but not changed it, have you heard of them going before ??? Link to comment Share on other sites More sharing options...
Tobes49 Posted April 20, 2004 Report Share Posted April 20, 2004 Thats the part, With the big silver heat sink. They can go wrong when they get hot and as soon as they call down start up again. Quite common. Normally called ignition amp or module. (cause the ignition switch is in the car) Link to comment Share on other sites More sharing options...
BURTON Posted April 29, 2004 Report Share Posted April 29, 2004 Does she run ok when driving etc? Is it only when you have been driving and come to a stop?? Link to comment Share on other sites More sharing options...
craiggolfmkII Posted April 30, 2004 Author Report Share Posted April 30, 2004 Thanks Tobes will try to get hold of one of those and try it... She cuts out anything from 45 minutes to 2.5 hours of driving, just complete loss of power with no indications or lights until you drop the clutch and then the ignition lights come on. Then just pull over wait 30 seconds and off she goes again, can be quite scary when your driving down a country lane at 60 with my little girl in the back... not nice at all with nowhere to pull over...

phulla Posted May 6, 2004 Report Share Posted May 6, 2004 I have a 1997 Mk3 8v and i am having the same trouble. I have had heard of others having the same problem, i have put some of the common problems on my website, http://ajmerphull.com/vw/vw.html I have changed the Engine Management Relay (#30 on mine) which is located in slot 3, top row of the fuse box. Costs about £10 from dealer. I have also been advised to change the fuel relay (~£20 from dealer), which i have purchased, but not changed yet, cuz i wanted to make sure it wasn't #30. I have checked the ignition switch, it doesn't seem to be faulty. I suppose i will change the relay as a matter of course. My cousins Mk3 1.8i also suffered with similar problem and he found the coil to be knackered, which he changed with a second hand part (£40) and it has solved the problem, £100+ from dealer.
