2004 1.4d Oil Filter Light with Battery light.

[Big Tank]

Both lights came on together last night, alternator bearing sounds noisy. I have put Battery on charge overnight and will take it down to my mechanic tommorrow. Anybody else had both lights together ? Car has done 122,000 miles. Fuel filter changed 2 years ago.

If Battery voltage is low you can get spurious signals...Suggest you sort out alternator/battery first.

I am assuming you mean the fuel filter light and not the oil filter light as per your title. 

 

The combination of the two lights (oil filter and Battery light) means you have an electrical issue somewhere in your system. Most likely your alternator is dying and need changing, measure the output voltage and it will tell you where the problem is.

Change the alternator, if you havn't already, its not fun when a bearing collapses on an alternator and seizes. Makes a nasty racket and destroys the belt
