Hey guys hope all is well!!

Where can we get hpfp's? Are there upgraded ones we can install or is oem better? Got a feeling my hpfp is on its way out.

If you supply pumps please pm me a price and lead times



Thanks in advance! :blowheart:

As far as I know these are agents only locally.

I brought one in from the UK recently, fitted yesterday. Will update my thread soon.

What symptoms are you having? Fault codes?

Morning gents.

My codes are SHADOW CODES - 2BDE fuel high pressure enabling on injection(pressure to low)

2bfo (all in German)

I used the mhd app to check the fault codes

That code does not tell much. You will have to log the Hpfp. Find a mech with a good diagnostic tool to log the the pump.

What symptoms is the car throwing?
Ps...i edited my post. I forgot you N55 without a lpfp sensor. So logging the hpfp will be important.

theres a company that has brought out hpfp for the n55 cars tuningtechfs/xdi
to my knowledge this is the only company on the market offering a hpfp upgrade

TTFS/XDI -35 HPFP Upgrade For N55
TTFS N55 Dual HPFP Factory Upgrade

but they between 2000-5000 dollars depending on which one you want they very expensive

The car takes a bit of time to start some mornings and the power is surging on wot, feels like it pulls timing then corrects again. Some days the car pulls like a demon then other days feels flat. Also a delay on the throttle car is a dct.

I will see if I can get a log done.

Hi, that figure seems plenty for that boost but how does your air fuel ratio look at that reading? The xdi pump upgrade is for the newer style hpfp, I think till 2012 135i had the n54 style pump. Old style

New style

The old style flows a bit more than new style btw.
