The 'Check Engine' light on our Linea came ON the other day . The service center guys had no clue , and after a lot of hit and trial the issue was solved when they drained some engine oil . The problem has started again . Could anyone tell me the reason for this . The blue and me system also stopped working some time back , for which they were demanding over Rs.12000 . Also suggest some service centers in Delhi if you could . Thanks !
