condensation in diesel

[petesta]

Hi reader

I have got my first Berlingo 1.9 diesel van that i believe is MK1 2001 (year)
and among st its problems is a light on the warning dash that i am told is fixed by replacing a filter (cost about £11)
and it is said that the cause is condensation in the fuel
also i am experiencing an intermittent bleep in the cabin and dont know if the two are connected .
If you can advise me , would be grateful

Hi & welcome.Change the fuel filter first & go from there.It wouldn't hurt to run some injector cleaner through it.
