Golf 7 2014 1.6 tdi. How often (if so) should I change glow plugs. It's milage 180000km (not miles). they have never been changed according to the papers I have from the dealer. So it is worth to change or how often in 1.6 tdi 105 bhp they should be replaced? I don't have any manual so different sources give different infos.

There is no change interval...you just change when they go faulty & throw up the glow plug light permanently on the dash...

Personally, I'd change them....Let the engine cool & spray where the plugs meet the engine block with penetrating oil. Leave the car overnight. The get the engine hot & remove the plugs while the engine is hot.

You might have to spray them every evening for say 3 nights before you try to remove them...the reason for this is that the glow plugs can snap off in the engine block....so its best to get penetrating oil/fluid into the threads especially if the car is older & the plugs have never been done!
