13 31 ... Notes on fuel pressure check (reference pressure: environment)

Feature of this version with ambient pressure

The connection for the vacuum hose of the fuel pressure regulator is located between the throttle and the air cleaner or on the air cleaner.

Test precondition

The correct fuel pressure regulator is fitted.

1. Using the EPC, check whether the fuel pressure regulator suitable for the car is fitted: Connect test adapter.

Description of operation

The control function of the fuel pressure regulator must be guaranteed under all operating conditions. The fuel pump must always be able to generate a higher fuel pressure than the pressure regulated by the pressure regulator.

The injection rate is adjusted by means of the injection time; the injection time is controlled by the DME.

Description of operation: fuel return line

When the engine is at a standstill and the ignition key is in position 0, the fuel return line after the pressure regulator is at zero pressure.

Description of operation: pressure retaining function

The pressure regulator closes when the engine is at a standstill and the ignition key is in position 0. The fuel pressure in the delivery line is retained over an extended period. A non-return valve closes in the fuel pump. These measures help to retain the fuel pressure in the fuel system. Extended starting times are thus avoided.

Complaint: drive characteristic faults, lack of power

1. Run engine at idle speed and measure fuel pressure.

If the measured value is less than the nominal value - 0.2 bar

1. Line cross-sections in fuel feed are constricted or fuel filter is clogged, or
2. Fuel pump voltage supply is not O.K.: e.g. as a result of high contact resistance (corrosion) in plug connection between wiring harness and fuel pump.

If the measured value is greater than the nominal value + 0.2 bar

1. Turn off engine stop and then observe measured value.
2. If measured value drops to nominal value, then line cross-sections in fuel return are constricted or clogged.
3. Check the fuel lines for kinks.

If no kinks are visible

1. Replace return lines

If measured value remains too high, then pressure regulator is in all probability faulty.

1. Have a cleaning cloth ready and catch and dispose of escaping fuel.
2. Replace the return line but not the pressure regulator.

Complaint: starting problems

1. Run engine briefly at idle speed and switch off.
2. Note down measured value while engine is stopped.
3. Read off measured value again after approx. 20 to 30 minutes while engine is stopped.

Special tool 13 3 010 (hose clamp) is required for the following test.

If the measured value has dropped by more than 0.5 bar

1. Start engine and wait briefly for a stable pressure increase.
2. Switch off the engine and immediately pinch off the delivery line just before the pressure gauge with the special tool 13 3 010 .
3. Note down measured value
4. Read off measured value again after approx. 20 to 30 minutes while engine is stopped

If the measured value has now dropped by less than 0.5 bar, the following faults can be present

1. Fault in delivery lines
2. Fault in in-tank delivery hose
3. Faulty pressure-holding non-return valve in fuel pump

Check components. Replace faulty components.

If the measured value has dropped by more than 0.5 bar again

1. Replace pressure regulator

Note. All the fuel hoses and hose clips which were detached within the framework of the checks must be replaced. Interrogate fault memory of DME control unit. Check stored fault messages. Rectify faults. Now clear the fault memory.

13 54 010 Performing throttle valve basic setting (S65)

Necessary preliminary tasks

2. Switch off ignition.
3. Remove intake air manifold. . See «11 61 050 REMOVING AND INSTALLING AIR INTAKE MANIFOLD (S65)»(/bmw/m3/e90-2007-2013/remont/mechanical/#engine-repair-e9293__11-61-050-removing-and-installing) .

Scheme 13

Checking throttle valve basic setting

Gap between stop screw (1) and actuator (2) of throttle valve must be less than 0.05 mm.

To check gap, use a feeler gauge with a thickness of 0.05 mm.

Checking gap

1. Pull pull rod of throttle valve actuator in opening direction of throttle valves.
2. Slide feeler gauge (3) between stop screw (1) and actuator (2) of throttle valve.
3. Return throttle valves slowly to stops.

Scheme 14

When correctly adjusted, feeler gauge will jam between stop screw (1) and actuator (2) of throttle valve.

Perform check on each throttle valve assembly.

Performing throttle valve basic setting

A basic setting must be performed if the gap is larger than 0.05 mm at one or more throttle valve assemblies.

Note. To perform correct throttle valve setting, it is necessary to slacken all the screw connections (3) of the actuating lever (2) with the actuating shaft (1). (Replace nuts). However, if increased play is ascertained, the corresponding cylinder bank must be reset. Do not slacken the screw connections of the actuating levers for the long pull rods. The long pull rods must not be disengaged from the actuating levers for the setting procedure.

Scheme 15

To slacken screw connection of actuating lever (1), grip screw (3) and release nut (2). (Replace nuts).

Release screw connections of actuating levers of throttle valve assemblies 1-4 and 5-8.

Scheme 16

Adjusting a throttle valve assembly

Move actuating lever (1) in direction of arrow, i.e. "close throttle valve", until actuator (2) of throttle valve rests without play on stop screw (3).

Scheme 17

Tighten down screw connection of actuating lever (1) again to actuating shaft. Observe the following instructions in so doing

1. Use nuts only once.
2. When pretightening screw connection (approx. 5 Nm), hold actuating lever (1) of throttle valve in direction of arrow at "close throttle valve".
3. Only turn nut and grip screw.
4. To screw down, use two open-end wrenches which are to be placed at right angles to actuating shaft. In this way, no lever action is exerted on the throttle valve mechanism; such torque would impair the quality of adjustment.
5. After pretightening actuating lever, actuate throttle valve several times at full load.

Note. If necessary, carry out adjustment with a second person.

Scheme 18

Adjusting throttle valve assemblies 1 - 4 and 5 - 8

The previously described procedure applies to adjusting/setting throttle valve assemblies 1 - 4 and 5 - 8.

Adjust throttle valve assemblies 1 - 4 and 5 - 8 in sequence.

After successfully completing throttle valve basic setting and checking, tighten down all screw connections of throttle valve levers to specified torque. See 13 54 1AZ in 13 54 THROTTLE VALVE ACTUATION (S65) .

Scheme 19

Note. After completing adjustment, it is necessary to check the throttle valve basic setting! If during the checking of one or more throttle valve assemblies excessively large or small play is ascertained, it will be necessary to perform the throttle valve basic setting again!

Note. Check stored fault messages. Then clear fault memory.
