Turbo coolant lines

mserafim · 02-23-2021, 01:33 PM

Hi all,
So my 2018 G11 750xi is having the usual problem - Turbo coolant lines are leaking, for now only one of them - you can see the videos attached ...

The dealer is asking around 2500$ to fix.
Now my question - considering that this seems to be an "usual" problem on most of the N63 engines ... is there any official recall for this issue ???

Mine is 2018 so I have the N63TU2.
Thank you

2500 from a dealership isn't a bad deal for that issue. I haven't seen a recall on it unfortunately even though the fix is to replace the rubber pipes with metal. Seems like they know they screwed up and found a solution yet we have to pay up for it

There was an SIB for 2016 and 2017, but looks similar to your 2018.

Looks like just the rubber hoses can be replaced, about $20 in parts for new hoses and clamps. The labor doesn't look bad at all.

I've heard there is a new design with metal braided hoses. I don't know anything other than that, but that would definitely be much more labor to replace.

Thank you - to me the SIB for 16-17 should apply actually to all N63's considering that if you just do a google search you will find aloooooot of people posting this issue.
Also it is only for the G12 ... that's really non-sense !

What I will do I'll send an email to BMW directly in Germany to see if someone is answering.
Will keep you updated on what type of hoses they will install ...

Let us know how it goes. Would be nice to get a refund for that repair if they do actually acknowledge the problem

I have line 2 for the return coolant line leaking pretty bad ATM. Filled up last night with coolant and this afternoon when I pulled out there was a pull of coolant on floor. Based off some pictures, (not sure what engine code), I've seen.. is it really that difficult to replace the coolant lines? I have a 2016 750ix G11 with n63tu2. Given i filled almost the whole reservoir the evening before I'm worried it's more then just line 2. And how does that SIB thing work?

Does anyone know the size of the hoses?
