P2181 Code 2 weeks after turbo install?

[tomahawk297]

So today I got a CEL and smelled something through the air conditioning that smelled like coolant. Went to Oreillys and came up with the code P2181 which has something to do with coolant, I just installed a rebuilt turbo two weeks ago and did a coolant flush so I'm not sure what would be the most likely cause of my problem. Any knowledge and advice is much appreciated! Thanks.

I was dealing with that for a while on my B6. It could be the coolant temp sensor in the back of the block (green sensor), or the faulty t-stat. Mine was a faulty t-stat. Code went away once I replaced the thermostat. Hope this helps.

I'll probably just order the thermostat and CTS and replace them in hopes that it's one or the other.
