Hi Kendo01,

You really need this on a diagnostics machine or vagcom, although I have come across similar before, although not to the extent of the engine dying, & this was down to the infamous brake pedal position switch.

What sounds like is happening is the esp etc is getting 1 signal & the engine another. It is also the brake pedal position switch which stops you over-revving it in neutral or with your foot on the brake, (in this case the revs should come down when you touch the brake, bit of a ****** for left foot braking though<S>).
I would probably say it's only that, but you really meed it diagnosing to confirm.

Hope this helps, & although it seems severe, it's probably a £10 sensor/switch at worse.

It could be the crankshaft sensor.
