Well I've just joined the forum as my jetta 2.0 tdi 140 sport gave me a code for glow plug number 1.

My question is this.....probably silly but number one I'm guessing is the one on my left if I'm facing the engine?? Just like a petrol? I'm no mechanic either lol but the thread on here I spotted makes it look simple, just worried I might break the glow plug if its to tight.....
