Hi all. Tried a search but to no avail.

Tried to remove the under trays today on my 2013 L320 to change the turbo drain pipe to the shorter one.

And that's as far as we got... Tried...

Not one bolt under there would budge, even with a breaker bar. Seems to me that the bolts have not been off for 10 years...

Any secrets out there to get them off, feels like they will either round over or snap, either way I think every one is going to have to be drilled out.

happy to take advice

someone must have had them off to change the oil ....or not
heat from a propane torch may shift them Always listen to old people or when they die you will live on in ignorance.

Tried heat...

Oil comes out the top with a vacuum pump for oil change,

Have you tried soaking them in penetrating oil for a couple of day's, then use a good six sided socket and impact wrench. Buy a tin of copper slip as well when they go back.

Thanks Col, that's my next approach....

Eh up

Good luck - I had the same issue if you look at my threads - turned into a saga 🤬😂

For what it’s worth it ultimately worked out quicker for me to grind off , drill out and retap.

I was there for days trying to get the little front piece off - funny now but not then🤬

I replaced all mine with stainless bolts and copper ease to boot.

Hope you get em shifted there a real PIA for what should be a simple job

Ah yes now you say it, I remember your thread...
