Hi, bought my Civic 1.7 CDTI 7th Generation 04 a few weeks ago. Been getting nearly 80mpg out of it on the motorway. However an inside light was left on which killed the battery, it would not recharge properly and created a tapping noise when the ignition turned to just electrics. Now we have just fitted a new battery, works great but still there is a fast tpping noise coming from the right hand side area near the battery. Anyone know what it is?
