About a week and a half ago I took out my egr valve and throttle body for a cleaning because I had a check engine code. I put everything back together, only to realize my coolant hose running from my turbo to the egr vavle (if I'm not mistaken) tore. So I got some hose from autozone to replace it. Everything was running fine, but now almost eveyday I have to fill up my reservoir. The weird thing is I don't see any severe leaking. I also places cardboard under to see if I was leaking, and it was bone dry. I sometimes get a burning coolant smell. Could the turbo be doing it or in the engine or something? Someone told me air might be in the system. Is that possible? Please help
