My R33 wont shut off straight Away after turning it off using the key.

[JohnOcampo]

My r33 doesnt shut off straight away after turning the key to off position. It runs for about 10.15 secs then shuts off. Seems  to be delayed. Any ideas why or how to fix it.

Verify that your spark plugs are not firing after key off first. If they are then you have some kind of wiring issue. If your spark plugs are not firing then your fuel injectors are leaking.

Has it always been like that? Does it have an alarm? It's an unusual time but may have a timer built into the alarm

[Duncan]

yes, it is most likely a turbo timer. If not in the alarm, back in the day they were pretty common as an extra box plugged into the back of the key switch's wiring. Take off the plastic under the steering column, trace back the large wires from the back of the key switch, and see if they lead to a small electronic box.

If so, they generally have 2 plugs (one male, one female) so you can just unplug both, move the box, and then just plug the remaining wires in the car back together to remove it.

Does the car turn off when you release the handbrake?

It should, if it doesn't whoever wired up the turbo timer and/or built in turbo timer in the alarm should be shot and have their hands cut off.

Also, turbo timers are gay.

Aaw, c'mon. Two points here. 1) Whilst I understand why the TT design includes the handbrake interlock, wiring it in is a complete pain in the arse, both in terms of actually wiring it in, and also in terms of having to pull on the handbrake before you turn off the key.

And 2)

I thought the whole point of a water cooled turbo was that it would keep the oil from coking?

Also not that difficult to just avoid getting into boost for the last minute or two of driving, sit there for 10-15 seconds idling before key off. Super simple and no need to screw up your harness with shoddy wiring.
