The thing to remember is don't force them. Andy's technique and use of no more than 25Nm is spot on.
I had 1 of 3 on my FL1 SE that absolutely refused to turn, so I didn't risk breaking it off.
I would expect nothing less!
It's my old F1, that is now with my daughter, that I'm more concerned about. Strange how it still finds it's way back here when it has a problem :rolleyes:π
If you need to replace the FL2 glow plugs, they are only tightened to 8Nm, so come out easily.
FL1 plugs are often tightened like they are spark plugs, which is completely unnecessary.
How to do the bonnet latch part is is well described in various threads. To actually unlock the doors you needs to access the diagnostic lines & have decent diagnostics.
@mowoh as I said in reply to your PM, I would need to see picture of you...
Had to remove 4 x glowplugs from my TD4 2005 recently.
None moved and I know, from a bench test of a broken one, that they snap at 30 ftlb.
I didn't want to break them so trawled for techniques that might work. This one looked reasonable and it...
