fault codes 12555, 04688

[Lee Riddlesden]

Hi, does anyone know what may have caused these codes (12555, 04688) on my Leon FR TFSI 2.0 07 reg. I have a diagnostic tool, but it couldn't give me any explaination for them. Had a look online, 12555 could be to do with fuel pressure regulation. No engine management light is shown on the dash board, which makes me think it may have something to do with the re-map.
Any help would be great cheers

Any problems with the car?

12555 is low pressure fueling issue - ie; fueling before it reaches the high pressure fuel pump, so this could be in-tank fuel pump issues or fuel filter, changed it recently?

04688 P1250 is Fuel level too low. may or may not be related to the above.

could your remap be too much for your fuel pump, is it standard?

 

[DanGB]

Intank fuel pump is usually good for around 400hp.

 

[GrahamFR]

I stand corrected, sorry not petrol so don't really know, but don't you need to change the fuel pump at stage 2+?

 

[DanGB]

Yes, stage 2+ is the High pressure fuel pump, which the standard one should be fine for a stage 1.
The particular codes are relating to the low pressure side.

 

[Lee Riddlesden]

No problems at all with the car. I ran out of petrol a couple of days ago. I bet this may have triggered it. What do u think? Fuel pump is standard.

 

[DanGB]

Well yes, that's exactly what triggered both. Clear them Case closed.

Nice one !!!! Cheers lads

Does fault code 12600 relate to this as well. Not sure if it was there already or if its just come up today

 

[DanGB]

Could be the intake manifold flap runner motor needs replacing, its a common fault on these.
