135i n55 hpfp

[Smashes6863]

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?

Yes start with reading the codes:thumbs:

 

[Smashes6863]

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

 

[Twinz]

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.

Hey gents so an update on the car eventually bought the logging module from mhd hpfp runs 2800psi rail pressure @17psi boost @wot

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.
