Hi everyone,

I know I'm not the first to have a problem with the fuel pump, I've read a few postings from people who have the same issue. However, I think I might be the first to have this problem on an E93 and also it's a 325 (328 stateside) not a 335.

It's a week 10 build (5 March 07).

It has all happened pretty quickly. The car has been fine until this morning (Saturday) when I had some starting problems, i.e. press the button, engine turns over for 2 - 3 seconds before firing - exactly the same as this http://s131.photobucket.com/albums/p...t=MVI_0583.flv.

Got onto the dealer who said to bring it in straight away. On the way to the dealer (7 mile journey) has a sudden loss of power and the engine cut out twice!!. They put it on diagnostics and lo-and-behold a faulty high pressure pump was found.

My dealer was excellent, but BMW need to sort this problem out. I've only done 650 miles from new and I don't expect there to be problems on a £40,000 car. :mad:

The part is on order and should be here by Tuesday (fat chance!!)

totally different pump than the 335i... you should have no problem getting that pump by tuesday

I don't think that engine even uses a high pressure fuel pump since it doesn't have the direct injection?? The U.S. 328 doesn't anyway.

[E90Fleet]

European E93 325i should have the new DI engine

[E90Fleet]

Did they first try a software upgrade?

The last recent built car with fuel pump warnings was due to the software calibration error, and not the pump itself

SUBJECT
E90, E92 with N54 - Diagnosis for DME FC 29DC/2FBF


MODEL
E90, E92 with N54 produced 06/06 up to 12/01/06


SITUATION I
Customer may complain of the following:

"Vehicle looses power while driving"; or "Vehicle runs poorly";

Service Engine Soon light may be illuminated;

GT1/DIS diagnosis shows fault code 29DC (Cylinder injection cut-out, pressure too low in high pressure system), 2FBF (Fuel pressure on-release injection, pressure too low), also in conjunction with 29F1 (Fuel high pressure, plausibility) and 29F2 (Fuel high pressure, fuel pressure undershot).

In some cases, also misfire faults for various cylinders (e.g. FC 20D1, 29CF, 29D2, 29CE, 29D0, 29CC) are stored in MSD80.

Important:

If only fault codes 29F1/29F2 are stored in DME, refer to SI B12 16 06 (November 2006).

SITUATION II
Customer may complain of:

Excessive cranking time before engine starts (5-6 seconds) on cold start, or after hot soak,

In most cases GT1/DIS diagnosis shows fault code 29DC, and/or 2FBF.

CAUSE
Sensitivity of the high pressure injection pump (HHP) diagnostic software.

CORRECTION
On a customer complaint basis only, and when the listed above fault codes are stored in DME memory:

1. Check vehicle's integration level.

2. If the integration level is found to be "E089-06-09-540", or lower, then reprogram/recode complete vehicle using PROGMAN V24.02, or higher (target integration level "E089-06-12-510", or higher).

3. Test drive vehicle after programming to verify effectiveness of the repair.

In case, vehicle was already reprogrammed with V24.02 (to the integration E089-06-12-510) and fault codes 29DC, and/or 2FBF/29F1/29F2 are found to be stored in DME; or a high pressure injection pump faults are coming during back during test drive after V24.02 reprogramming then:

Perform all applicable DIS/GT1 test plans, mainly B1214_ DI6KHDR/NDR (high pressure fuel system, rail pressure sensor, volume control valve test), and B1612_ STR/SPG/VER (low pressure fuel system check). Test modules may be accessed using the path: Function selection; Drive; Motor Electronics; then High-pressure/Low-pressure fuel system; Test plan.

Make sure that a FASTA data is transmitted after completion of all appropriate test modules.

Replace the high pressure fuel pump, when prompted by the results of DIS/GT1 test plans. For the pump replacement procedure refer to RA 13 51 017 found in BMW TIS.

After replacement, clear adaptation values of the high pressure flow control valve in the DME. Refer to SI B12 16 06 for adaptation reset procedure.

Thanks very much for that , I'll pass it onto my SA on monday.

I think this forum rocks!!

That TSB is for N54... does he have an N54 ????

He should have a N53

But as i said, it may help, since they will have similar pumps.

If it doesnt work, he just has to wait for the pump to arrive
If it works, great

Sorry to hear of your problems, hope Snows sort it on tuesday, did they provide you with a loan car til then?

These things always seems to happen over the weekend, my E46 had several ignition coils go west, always over a weekend!!! - then they have to order the part on a monday for tuesday delivery!!

[MacAttack]

Does the 325 have the Siemens fuel pump as well? Sounds like it.

Hi Alan,

They gave me a 118D. It's all they had on short notice. At leat I got something I suppose.
