Audi S3 8P 2007 BHZ engine Hi everyone. Time has come to replace the low pressure fuel pump. OEM part number is 1K0919051AS, however I can't find a part with this number. All car parts websites indicate that 1K0919051DE is the latest revision, so I went ahead and ordered a VDO OEM one. The car...

Anyone?

Flip the bulb around and insert it into the socket. If that doesnt work, clear the codes in cent. elect module.

Hi all! What's the latest revision part number of the thrust sensor for the low pressure side of the hpfp? Which part manifacturer is the OE supplier? All I could find is the following part number - 06E906051K, however Bosch doesn't seem to make this part, only previous revisions ending with B...

I thought stage 2 would request more in terms of fuel and boost than stage 1+? How much boost does stage 1, 2 and 2+ require? What about rail pressures between all stages? Thanks for the link, hopefully I'll see some improvement after replacing this hose. That's the proper way of doing...

AFAIK the HPFP should keep up until stage 2, anything more than that would require an upgrade. In my case, it gives up completely as soon as more boost is requested. LPFP seems to be performing adequete throughout the rev range, without pressure drops. Duty cycle at idle is around 45-48% so it...

Hi everyone! Got a bit of a problem with my S3 8P BHZ. On stock software, the car is running great, however when stage 1 is applied, HPFP starts to struggle hard and rail pressure drops massively. Mods wise, car has a 3" downpipe with middle section, RAMAIR intake and red top coils. Fuel filter...
