Help: Code P10D9 Very hard start.

Scantrell · 06-03-2019, 03:34 PM

Well I thought my issues where solved seems like these cars are nothing but problems.
Checked all connections everything is right. Car won't start now. I installed the hpfp 2 days ago it worked fine until this morning it wouldn't start after trying about 15 times I finally got it to stay running but was idling very rough. Itll start back up when car is still hot but once it cools down it's hard to start. Getting code P10D9 while driving car is barley making power almost like limp mode.

I was looking around the hpfp and I noticed the round drum piece with the lip around it came off the hpfp. I put it back into the pump maybe that's what's causing this there was also alot of oil around it.

(I plan to swap the fuel pressure sensor tomorrow) if anyone else has had something like this happen please help.

hooked up to MHD these are my codes
DME Active Codes
-2BEE- High Fuel Pressure, Plausibly, Cold Start: Pressure to low.
-2E0F- valvetronic system: deactivated , adjustment fault to frequent.

DME Shadow Codes
-2BDE - Fuel High Pressure During Fuel Injection Release: Pressure to low

From what im seeing this could be your fuel regulator. Reason why "Pressure is too low" upon start up. If youve already checked the HPFP/Sensor. its time to check under the seats my man.

Well installed a new regulator and It did nothing same exact issue. New lpfp comes tomorrow and another high pressure sensor(maybe the first new one was faulty) if that doesn't fix it I honestly don't know what to do. Maybe put the orginal hpfp back on and see if that fixes it

Then continue to tackle around the fuel system. Check your LPFP next. try to start with low cost before HPFP replacement, IMO it is definitely fuel related

I agree I think it is definitely fuel related. I have a feeling its something going on with the electrical side of things. When I swapped the new sensor from BMW on It I got a code(2BDA) that said I had a short to earth. I have another sensor coming today a long with a new lpfp. I'm hoping it's not the hpfp I just bought it. It was used with only 30k miles. It worked for 2 days perfectly then these problems occurred and I've talked to the guy already and he said he wouldn't refund me if it was the hpfp that failed after 2 days.

Sounds like he sold you some bullshet, That's one reason why i don't like buying used fueling parts. If paid with PayPal try to disputing the payment. Keep us updated, i hope replacing the hpfp isn't the case but i would consider it after accessing all other fueling components.

2BDA - Rail pressure sensor, electrical: Short circuit to ground

He told me he can't warranty a used part that worked fine when he sold it. I think a hpfp with 30k miles should last more then 2 days(if that is what's causing the issue) he then went on to say that I could have installed it wrong and maybe damaged it. I've been working on cars my whole life and I also had a certified mechanic working on it with me so I highly doubt its something I did wrong. A hpfp install is pretty straightforward I don't see how it could be done wrong.
I honestly hope he didn't he's been on the e90post a while so I trusted him. But I did buy through PayPal with goods and services so maybe I can dispute if it does come down to it.

Any idea's on what would cause the 2BDA code? This was the only code I received when I swapped the new sensor from BMW in. Still had same issues just a different code.

Check Fuel Rail Sensor for dirt/damage, Follow wires down and see if there's any heat damage or not a good ground connection.

Post a log here of the mhd logging will all parameters available and just log attempting to start. Idl like to review that log.

I have to use jb4 to log but sure I should be able to get a log when I get home from work.

Scantrell · 06-11-2019, 06:33 PM

New lpfp still same problems. The jb4 log isn't showing anything for the high pressure side. Maybe I'm doing something wrong I dont know but I'll post the log

It was the used hpfp that went bad.(the user checkered sold it to me) I put my old one back on and car runs. I had it on my car for 2 days and the guy refused to give me a refund. Hpfp with aparently only 30k miles fails after installed for 2 days. This guys full of shi

I mean 30k miles and he said it was replaced under the recall so I was updated? sounds pretty good to me. I usually have trust for people on this forum so I figure it'd be good. I was definitely wrong.

Scantrell · 06-17-2019, 09:55 AM

PayPal is forcing him to refund me after I return it. I'd recommend not doing any buisness with the user checkered

lwgrenier · 06-20-2019, 12:10 PM

30k is like half the life of the pump... not sure if FCP still has them but buy one from them with the lifetime warranty.
