Problem with launch control

[T77OMY]

My launch control doesn't work every time?

I believe it should explain the workings of you launch control in the owners manual.

However what you'll probably find is; launch control can be very stressful on the engine, gearbox and drive train.

Audi program in safety features to prevent damage to the car. You will find launch control will not work unless certain criteria is met.

If the engine/gearbox is too hot it will not launch until it's had time too cool down.

If the engine hasn't warmed up to operating temperature it likely will not launch either.

A lot of people don't realise frequent abuse of Launch Control can damage your engine. Same way a lot of people don't know you need to warm up a car, especially a turbo charged car, before you can safely put it through it's paces. You'll find most modern cars have these fail safes and it'll prevent you having very expensive bills further down the line. It should also state in your owners manual that launch control subjects your car to heavy stresses and can increase wear and if improperly used cause damage.

Edit: Some rumours also suggest there is a limit on how many times you can use launch control. If you go over the limit your warranty is no longer valid or launch control will stop working permanently. They say about 200 uses apparently.

Unless your in a race I don't see the point of using launch control with the increased wear and risk of damage.
