Carson.simon Posted March 12, 2017 Share Posted March 12, 2017 Hi. Got a small issue with my a3. Eml light came on again after getting system lean bank 1 before. Checking all the hoses for splits etc and this one just breaks off in my hand... There is some oil residue around the area where its been broken aswell...looking to find out what it actuly does...im guessing it could be the cause of my issues...

Trevor Posted March 15, 2017 Share Posted March 15, 2017 Hi Simon Yep, that looks like it could be the cause. It is a oil breather hose which will go into the inlet somewhere along the line to be burnt in combustion. Once fixed/replaced, that should sort the error Cheers Trevor 1 Quote Link to comment Share on other sites More sharing options...
