So kept smelling a toxic burning plastic smell and thought it was some of the brittle plastic clip holders that break last time I changed the vacuum pump seal, but lo and behold it was the turbo cooling lines on top!

Symptoms also include seeing some green crud around the fittings and obvious dripping.

BMW Wants about 400$ for all the lines but it seems like the only parts that leak are between the rubber hose and the metal line. Can you say "new hose clamp" ??

So i did that but after a time leaks again. So it seems the hoses them self break down and you just need to change them. The whole job will cost you less than 20$.

One of the pics below you will see how the hoses can really start to crack and break down.

Need to get some lower profile screw type hose clamps for the "T" connection.

Sorry the first pic is the completed job. I attached it wrong on my phone.

Did the same thing on three of the hose ends. It's a shame that these are failing so quickly, but the replacement/repair is pretty straightforward.

Thanks for posting.

Nice DIY.. i had the burning smell too. BMW of NWA couldn't reproduce the smell lol. Baron BMW in KC knew what it was in 15 seconds of popping off the engine cover.. in the parking lot.
