I had the same problem and it turned out to be a missing bolt that fixed the wing to the car.

I'm pretty sure i should have a 3bar filter/regulator on my car. I also found a good website showing part numbers for various parts and the below link seems to confirm my thoughts. http://www.vehiclepartsdatabase.com/vehicles/allprivateroadvehicles/volkswagen/polo/12/awy/19720/fuelfilters/alcofilter...

I have a rich mixture fault at times although the car runs fine and emissions are spot on.

Thats the reason for my question because i am thinking that the higher fuel pressure may be causing my issues.

Thanks for that.

The reg is AO55YBV.

From everything i can find online i believe it should be a 3bar filter/regulator but it would be great to have confirmation.

Hi
I have a 2005 1.2 Polo engine code BMD .
Can anyone tell me the correct fuel filter that i need as i believe it should be a fuel filter with a built in 3bar regulator.
It has a fuel filter fitted that has 4bar stamped on it.
Some confirmation of the correct one would be great.

Yes they are , they have both been replaced and made no difference.

The long term fuel trim is always a negative figure , like -15%.
The short term fuel trim seems ok alternating between positive and negative.

My son has a 2005 VW Polo 1.2 engine code BMD. It brings up P0172 rich mixture fault code after a few days and puts the engine light on. It still runs lovely with no misfire or loss of power. I have fitted another cylinder head with new ex valves and guides as no3 cylinder valve guide was worn badly...
