Mk5 gti & mk2 leon lpfp the same? Fuel issues!!!
« on: July 15, 2021, 09:31:01 pm »
Hi everyone,
I'm currently driving a mk2 leon cupra as I sold my edition 30.

Due a remap at r-tech next weekend, ive been waiting over 3 months for the slot but getting  error code 012555 - p310b- 002 - fuel pressure outside specification.

I have changed the filter and the thrust sensor next to the hpfp so presuming its the lower pressure fuel pump....(fingers crossed!?)

If anyone has any other ideas?

After lots of forum searching I've found a couple but they are for the mk5gti...but does that mean it would fit the seat?

Thanks in advance!

only way to know for sure is to do some live logging with vcds to look at your fuel pressure values throughout the full rev range.
Without traction power is nothing!

Okay thats a really good point!
Mechanic did crimp the fuel pipe slightly then released it again and then the pressure went up which would make you think the pump is capable!?
Thanks
