Found a coolant leak

Post by JPC-BMW » Wed Jan 18, 2017 6:32 pm

Coolant warning light came on the wife's F20 116i today so had a look for the leak.

Fairly certain I've found it on a metal pipe which attaches to the right hand side of the engine at that point.

It is situated just under the front part of the turbo, where they air intake goes into the turbo.

Hard to describe!

It looks like it has a nut or some form of threaded end to it, so my question is how do I go about accessing it to either remove / replace or try tightening it up? Is it going to require me taking the turbo out, or can it be done with a bit of patience and the correct angle?

Or should I not even bother attempting it and take it to a mechanic?

I haven't had a chance to look at it further yet as it appears to be a very small leak.

From looking at the diagram it seems there is a rubber washer which is probably the thing which has failed howeve cannot be sure without looking at it. It's been way too cold to fiddle about under the bonnet!

I may see if I can get access to it and check it isn't just a case of tightening it up slightly if I can reach with a spanner without having to take the turbo off!

However I feel that is unlikely to be a fix, so will likely pop it into a garage to be done.

I think i may have fixed this leak just by making sure the pipe is pushed all the way onto to connector at the engine end easy enought to do if you remove to intake pipe for a little room to move then undo the pipe clip on the rubber end and push the pipe onto its connector fully hope this helps :D

I think I have this very same issue. Slow coolant loss and I can see fresh this area is slightly wet after a journey. And there's dried red coolant all around it. I take it I just need to clean it up and push the connector in? No twisting?

It's the metal pipe below going into the top right hand corner of the engine. Underneath the turbo.
