Mk5 General Area / Re: Mk5 GTi stage 1 fuel pressure problems

« Last post by Lassebongo on Yesterday at 01:25:53 pm »

ok so problem persists... ive swapped the seal to the pump and the g410 sensor because of the fault code which is now gone.
Car runs but at first cold start the car stalls after a few seconds, keeping at it until the engine is warmer(choke goes away) it stays on during idle. Barely drivable, just a tad to much on throttle it starts to stall, if i let go of the throttle it stays on but if i keep the throttle on it shuts off. Logs say stable pressure on idle but pressure drops to under 2 bar with a bit of throttle. Is the pump the wrong one ?
This one has a closed top with the filter covering the whole bottom, old one was an open top bucket.


It was marked with the part number 1K0919051DB when i bought it.

I also tested with my old pump relay module which showed very erratic swings on the low side pressure. The log posted is with the new relay.

Gentle bump - anyone any ideas? I'm not sure what other things I could check or try to diagnose.

Seems once the car has adjusted after being started then the difference in rail pressure only is 1-2bar from requested but when first started after a reset any throttle and it’s 45bar difference. Im reading this could be the pressure sensor, HPFP or maybe my replacement injector. Which is more likely?

Mk5 General Area / Anyone identify this bumper?

« Last post by Marticus on September 15, 2025, 11:38:39 pm »

Found it on Google, from an insta post but didn't see any info.

Looks a bit like the alpil one from Japan but slightly different.

Any ideas?

As long as it looks the same ---, as the lesser spec Golfs have the brake carrier integral to the hub where as the GTI has seperate carriers. Wheel bearings are different too.

VCDS Arrived. Getting misfires across all cylinders, mainly 3/4. Still P2293. Checking measuring blocks it seems my fuel rail pressure drops massively from 50 to 5 bar when I give the car any throttle. Could my replacement injector be the cause of this? Changing it again might be the best option I think.

Fitted the new Meyle low pressure fuel pump to my Edition 30.  Have only had 1 cold start since installing it as I've been away, but unfortunately it still spluttered into life (without priming it, to test new fuel pump)

Where there is a massive difference is the drive of the car since replacing the fuel pump - MPG is way up, I was struggling to get 29/30mpg despite driving sensibly for long periods and it had been like that for quite some time, I just put it down to being an older car, less economical etc etc.  It turns out this is not the case, and on the 2 drives I've had since replacing, I easily obtained around 34/35mpg for the whole journey, despite spirited driving and when trying to drive it frugally, obtained 39mpg!   On top of this, the car feels MUCH more urgent and nippy at lower rpms,  needing less throttle input to get it going, so maybe wasn't getting the fueling it needed.

Worth checking your low pressure fuel pump if you have bad MPG.  I'll do a couple more cold starts before admitting that I still have that issue, but at least it has been positive in other areas.
