Fixing VW Golf/Seat Leon MK4 ASR Light Intermittent - Comes On After 10 minutes driving

A common problem on the VW Golf Mk4 is the ASR light coming on after around 10 minutes driving. This happens because the ASR system is looking for a load signal from the alternator and when it isn't detected it times out which happens after around 10 minutes. If you turn the engine off and back on again the light will go out again and come on after another 10 minutes but how do you fix the ASR/ESP light so it doesn't come on long term?

The fix is a straightforward repair to the cable that runs from the alternator across the gearbox to rejoin the ends that have broken. It's easily visible but you may need to replace the plug as the wires can be quite embedded inside it.

VW Golf MK4 ESP/ASR Light Fault Warning after 10 minutes

A common fault on the VW Golf MK4 is that the ASR or ESP Light can show a fault and display warning light on the dashboard after driving for about 10 minutes. This is normally due to a wiring fault. The ASR/ESP module is waiting for a signal for the alternator load and if this isn't found after 10 minutes then the system shows a fault and error code on the dashboard light.

The most common place for the wiring to break is just above the gearbox where there is a connector with 4 wires coming from the alternator and disappearing under the battery tray.
