    Heat exchanger m54 automatic

    Looks like I have a small leak of coolant coming from where the radiator pipes connect to this, has any one any experience with these, Google isn't giving me any info, don't want to have to fork out on a replacement if possible, cheers, Nigel

    Make 100% sure it isn't the expansion bottle above it before going off for repair that might not do anything. They're notorious on the e46 M54 for leaking and would drip right down on that area where the pipes connect.

    Yeah cheers Owen I did kinda hope that might be it but I'm nearly sure it's coming from where the radiator pipe connects to it, I'm planning on replacing the expansion tank shortly but budget is a bit tight so would love to be able to fix the leak asap wherever it's coming from before anything else
