The reason why I don't think the
Ibiza needs one is because when you are driving up your drive or in the car park your not going to be driving on boost. Therefore the oil will move out and the turbo will cool down.
I think they may interfer with the locking system or throw a code for the immobilizer but can't remember and am not 100% sure.
Also...how many of you would walk away from your car with the engine running, regardless of if the doors were locked or not. I know I wouldn't and if I'm going to stand there I might as well be in the car sat down and comfy
Don't get me wrong...I think these products are brilliant...I just can't see the justification in spending £££ for a good one when I can do the same thing by sitting in the car for a couple of extra minutes and spend the money on something else
That's my 2pence worth anyway
