I was going g to change the glow plugs today, by however this proved tricky as they appear to have made it extremely difficult in doing. I'm assuming the plugs are on the front of the engine behind the big silver metal block, meaning you have to take half the engine apart and get to stupid hex bolts that are nigh on impossible to get to (without a special tool I'm guessing).

I have the 2.0L version. I'm hoping there is an easier way or I'm looking in the wrong place......
