What would cause a combination of P0304 and P2293 OBD codes on a 2007 Passat 2.0T?


P0204 is miss fire detected on #4 cylinder.

Below is TSB from VW on your problem...a common one.


Technical Product Literature Transaction No.: 2015153/1
MIL ON, DTC P0087, P1093 or P2293 Stored in ECM Fault Memory Release date: Jun 29, 2007
Condition
15 07 04 June 29, 2007 2015153
MIL ON, DTC P0087, P1093 or P2293 Stored in ECM Fault Memory
MIL ON with the following DTCs may be stored in ECM fault memory:
DTC Description
P0087 Fuel Rail / System Pressure - Too Low
P1093 Fuel Trim 2, Bank 1 Malfunction
P2293 Fuel Pressure Regulator 2 Performance

Technical Background
Excessive wear of intake camshaft lobe that drives the high pressure fuel pump. The wear limits maximum pump piston lift, causing fuel rail pressure fluctuations.
The wear on the camshaft lobe can also lead to wear on the base of the high pressure fuel pump cam follower.
Production Solution
Increase surface hardening of camshaft lobe for the high pressure fuel pump
Improved intake camshafts have Part No. 06F109101B.
Service

• Remove the high pressure fuel pump and visually inspect:
1. Base surface of the cam follower -6- in contact with the camshaft lobe.
2. Tip of the high pressure fuel pump plunger.
3. High pressure fuel pump camshaft lobe.

If the base of the cam shaft follower looks like -C- or -D-, no excessive wear is present.
Cam follower and camshaft should not be replaced.
If the cam follower base surface is excessively worn so that its surface is concave -B- or missing -A-, inspect the intake cam shaft lobe for wear.

If the high pressure fuel pump camshaft lobe shows excessive wear, replace the intake camshaft with Part No. 06F109101B and the cam follower with Part No. 06D109309C, see Group 15 Engine - Cylinder head, Valvetrain in ElsaWeb.

Inspect the tip of the high pressure fuel pump plunger for excessive wear.
If excessive wear is found the high pressure pump must also be replaced, see Group 20 Fuel supply in ElsaWeb.
Tip:
High pressure fuel pump plunger damage is only possible if the cam follower base has a hole in it and the plunger tip has come in direct contact with the camshaft lobe.
If no excessive wear can be found in the high pressure fuel pump cam follower or intake camshaft lobe, or if the damage is found in camshafts with part number 06F 109 101 B, create a Technical Assistance Contact Ticket under the Concern Type Engine and Engine Electronics in ElsaWeb.
Attach the complete diagnostic log to the contact, and call the VW Technical Assistance Center for further assistance.

Diagnostic Test code (DTC) P0191 has a generic description which reads "Fuel Rail Pressure (FRP)Sensor Circuit Performance"

This code sets when the Powertrain Control Module (PCM) is monitoring the fuel rail pressure sensor signal under certain driving conditions. The FRP sensor varies return voltage to the PCM to indicate the fuel pressure at the fuel rail on the engine. DTC P0191 sets when the voltage received from the FRP is above or below the expected "range" or "threshold".

The possible causes of this code are:

> High fuel pressure
> Low fuel pressure
> Damaged Fuel Rail Pressure Sensor (FRP)
> Excessive resistance in FRP circuits.
> Low or no fuel

With all of that said, I would recommend that if you have more than 30,000 miles on your current fuel filter, I would try that FIRST. Replace the filter and clear the code. If the code returns, then diagnostics will need to be performed to find the actual cause.

Hello,

A code P1092 for your vehicle says the fuel trims are trying to add fuel and the limit has been reached and this throws this code. More specifically Pre-Catalyst Fuel Trim Too Rich Bank 2. A rich condition could be caused by several things. You could have a faulty fuel pressure regulator, a leaking fuel injector or a clogged air filter. I would check the air filter to see if it needs replaced and have the code reset. If it comes back on then you will have to go to a technician and have them pull the actual BMW fault code with their scanner.
Regards, Tony

P1093: Fuel pressure low during power enhancement

Check the oil and see if it smells like diesel. Sounds like an injector stuck open.
The LB7 trucks have injector warranty extended to 200k, so I would think about calling the dealer.

DTC P1093
Fuel Rail Pressure Low During Power Enrichment



The engine control module (ECM) uses the fuel rail pressure (FRP) sensor to determine fuel pressure to the fuel injectors. This is then compared to the calculated target fuel pressure as determined by the ECM. The ECM adjusts the FRP by modulating the duty cycle of the control driver of the fuel pressure regulator. Injector pulse duration is determined by the measured rail pressure and the target injection fuel into each cylinder. If a sensor circuit malfunction is detected, or the commanded fuel injection pump flow is not within the proper range for a given engine load and speed, DTCs will be set.

DTC U1000 and U1255 Circuit Description Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the identification number of the module which sent the message for State of Health monitoring. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. When a module does not associate an identification number with at least one critical parameter within about five seconds of beginning serial data communication, DTC U1000 or U1255 is set. When more than one critical parameter does not have an identification number associated with it, the DTC will only be reported once. The class 2 serial data line on this vehicle is a ring/star configuration. The following modules communicate on the class 2 serial data line:
• The body control module (BCM) • The digital radio reciever • The driver door module (DDM) • The electronic brake control module (EBCM) • The front passenger door module (FPDM) • The HVAC control module • The inflatable restraint sensing and diagnostic module (SDM) • The instrument panel cluster (IPC) • The memory seat module (MSM) • The powertrain control module (PCM) • The radio • The radio amplifier • The rear seat audio (RSA) controller • The rear seat entertainment (RSE) assembly w/U42 • The rear wheel steering control module • The remote playback device-CD player w/U1S • The transfer case shift control module • The transmission control module (TCM) w/Allison transmission • The theft deterrent control module • The vehicle communication interface module (VCIM) w/UE1
