Ok, newbie here. My 2011 335d is fully out of CPO warranty (57k miles) and time to start doing my own work.

I've been reading and reading and watching videos. I have a couple of glow plug codes for #2 and #5. #2 was first, #5 was a few weeks later. I've successfully removed intake (first time of many I'm sure) and I have 6 new plugs and a new module on the way. I'm going to guess the module is going bad since two plugs in short succession but I figured I would just replace everything since I have it apart.

My question is this... My engine is cold since I'm taking my time on this job (DC Summer so 80+ degrees) and the #2 plug came out with fairly little effort. THEN I started reading about the horror of snapping these plugs or bitching up the threads and how it should be done with a hot engine. Well, I can't run my motor at the moment since it's disassembled.

Any advice on how to proceed? I've tried the others and they are not coming out as easy so I've stopped. I don't have a meat fist and always err on the side of caution with potentially seized things. Can I heat the block somehow or freeze the plug to help?

Or should I just replace module and put it back together and see if the codes go away and then try later with a hot engine?

Also, what is the consensus on using anti-seize on the glow plug threads?

Thanks much!
