Hi all,
I bought last week a 9n 2003 Polo 1.4 75HP BBY. I want to change the fuil filter, but I don’t know that which one should I buy, because there are 3 BAR and 4 BAR too. What is the difference between 3 and 4 bar? Which one should I buy?

I have the same model, 2002. I changed the fuel filter last summer and as I recall it is 3bar for the BBY engine. You also need to check that the filter has the correct pipe fittings for return etc. Best thing is to look under the rear of the vehicle just in front the rear offside wheel and confirm. When you come to replace the filter make sure you release the pressure and take safety precautions. Be careful not to damage the plastic pipe fittings when removing them. Check for correct fitting and leaks after.
