Hi, how l fix the code on my vw golf 96 the code is po341 ?

The code po341 is camshaft position sensor is faulty, you will need to replace the sensor locate behind cam gear. I would pick up Haynes auto repair book for 20 bucks, it will give you instruction on camshaft tear down and it has pictures, great tools to have if you planing to do your own work, its not easy tasks and on top of that its time consuming. the part will cost ya 47 bucks.

Dude on a 96 jetta you dont have a camshaft sensor the code is generic in most cases that its your knock sensor or O2 sensor to solve your problem it happened to me... some poeple will also tell you about a hall sender or refrance sender there both one its inside your distributor, but its not gonna be the answer to your delama.
