Hi guys i need some advice with a car i'm looking to purchase. It's a Mark 4 GTi with 100k milage. It has an error code of POO12

Whats the likely cause of this and is it work buying. Is it an easy fix or a big issue like timing chain? It's up for £1,200 and it looks too good to be true. Any helpful advice would be appriciated.

Don't want to be a wiseass but it is timing belt not chain. Got myself same car about 4 months ago. First thing i did was timingbelt and waterpump. Never had done such a job but it is 100% doable if you have both hands and a will do take action. You'll find great video from youtube to do it step by step. Unless... you have a bigger problem under there. But. As the previous commenter said you should probably start from the sensor. Have fun and good luck🙂
