012555 - Low Pressure Fuel regulation
« on: May 23, 2010, 11:53:00 pm »
I drive a seat leon FR but it has the same BWA engine in the golf t with the KO3 turbo, and its on stage2+ upgrades (autotech HPFP).

I been out for a drive today on the mountain routes and going at a quick pace alot of bends etc ...after driving for about 100miles+ the car started to choke/cough but no engine light on the dash anyways i stopped for a bit and let the engine cool off (temp was okay on the dash). after about 30min break we drove off again I was a bit worried so I took it easy but it never happened again so far..after the event I went back home and did a auto scan using vagcom and came up with a fault hope you guys can help with this.

You should also check your cam follower should the problem not lie with the low pressure fuel sensor.
Without traction power is nothing!

Cam follower was replaced recently along with HPFP Internals not had any issues until today however after a break (30mins, Left the car on idle then switched off) the car seems alright now but this is the error I recieved after doing the auto check with vagcom.
