Hi I have a 2012 1.6 green line Octavia. I was getting work done on the dpf and the guy had it hooked up to his computer and a fault came up with the fuel filter he said that the fuel filter meter head had been replaced with a 2.0 litre meter head and was causing it to go into limp mode at higher revs. Does anyone know what this is and where to get one 

Thanks

It's actually the fuel filter cover. It seems to be leaking and the mechanic reckoned it is the wrong cover on it.

I would see your dealer for a part number, might have to buy the whole filter from them

They collect water then rust and can become perforated and leak.
