Title: Engine 'shutting down' after 15 minutes
Post by: john87 on October 23, 2015, 08:35:29 am
Yesterday was the first time I'd drove my R32 after two weeks, and it started and drove as per usual.

On the road home, I pulled away from some traffic lights when suddenly all the gauges dropped to zero and I lost all power. I pulled over, and tried to restart, however no lights appeared on the dashboard, as if the battery was dead.. however the stereo and headlights stayed on as normal  :confused:

After a walk round the car, I tried again and it started as if nothing had happened!

The same situation occurred again today after approximately the same amount of time. After a quick google, I found a post relating to a faulty ignition relay.

Has anyone else had a similar issue? I'm going to Vagcom it tonight to see if it's raised any codes.

Same happened to me in my R32 although the instrument cluster was cutting out and flashing on and off. Was traced to a faulty main relay in the fuse box in the engine bay. There was a revised part released some time ago.

That's exactly what is was  :happy2: ignition main circuit relay.. ended up calling the AA out after the car cut out 5 times within 10 minutes. Guy was an Edition 30 owner and knew his way round a Golf  :drinking:

so the VW dealer has found the fault on mine, apparently its the terminal 15 supply relay 433?

That sounds about right, can't remember exactly what relay it was but it controlled part of the ignition circuit and began with 4**

there are 2 relays in the engine bay fuse box, both are to do with the main ignition circuit it was one of those, no issues since the fault was repaired, but £80 odd for the diagnostics and the part, to be fair they had the car for a week and ran it about 10 times so they weren't to harsh with the charges!
