16 00 General Function Description For Fuel Supply Systems
Fuel supply systems, spark-ignition engines
Fuel system
The electric fuel pump in the fuel tank generates the pressure in the fuel system which is set by the pressure regulator to a specific level.
Tank venting system
The tank venting system is an enclosed system which is vented via a carbon canister. The carbon is incorporated in the carbon canister as granulate. The large surface of the carbon stores the fuel vapors which occur in the fuel tank. The carbon canister must be regenerated on a regular basis so as to be able to continue storing fuel vapors. Regeneration is performed by way of purging with fresh air via the intake manifold. This process is controlled by the engine control unit.
Fuel supply systems, diesel engines
Fuel system
The electric fuel pump in the fuel tank supplies the engine with fuel. Two types of high-pressure pump are used for cylinder injection.
- The distributor injection pump supplies each cylinder directly with fuel via the corresponding injection nozzle.
- The high-pressure pump for the common rail systems generates in the fuel rail the necessary pressure for all the injection nozzles.
In common rail systems, a further pump (inline pump, M57/gear pump, M67) is connected between the high - pressure pump and the electric fuel pump. This pump supports the fuel pump in the fuel tank in the event of a high fuel demand.
Tank venting system
Diesel fuel is non-volatile and therefore a carbon canister is not required. The fuel tank is vented directly to atmosphere.

| IMPORTANT | Observe country-specific safety regulations. Ensure adequate ventilation in the place of work! Connect the exhaust and extraction systems to the exhaust tailpipe. The electric fuel pump must not operate without fuel! After completing repairs but before starting the engine for the first time, fill the fuel tank with min. 5 l fuel through the fuel filler pipe. Do not damage non-return flap when pulling out extraction hose. |
Diesel vehicles
Before starting the engine for the first time, if the tank has been run dry or drawn off, fill with diesel fuel and turn on ignition for approx. 1 minute. The fuel circuit is thus filled and vented, which results in the engine firing more quickly.
Drawing off fuel
Start engine and allow to run.
The electric fuel pump runs.
In this way, the fuel is repumped through the suction jet pump from the left to the right side of the fuel tank.
Note. Fuel can be drawn out of left and right sides of tank through filler neck, leaving only a small residue. The residual quantity is drawn off through the service opening (on right/left).

16 00 102 Checking Fuel Tank And Tank Venting System For Leaks With Tank Leakage Diagnosis Module (DM-TL)
Note. An OBD fault is indicated by the "Check Engine" indicator lamp in the instrument cluster lighting up. This may indicate a leak in the tank venting system. Information on this is provided by the fault memory of the DME control unit.
- Read out fault memory of DME control unit and carry out a diagnosis in accordance with faults stored.
- A leak test with the DM-TL module is then carried out if: The components of the DM-TL module are O.K. A fault is stored in the DME fault memory (tank leak detected).
Adhere to following conditions in order to carry out a correct leak test
- Content of fuel tank < 90 %
- Reserve indicator lamp "off"
- Leave car in workshop for at least 2 hours so that fuel temperature comes into line with workshop temperature (ideal fuel temperature approx. 10...20 °C).
- Do not under any circumstances fill up car with fresh fuel (strong exhalation of fresh fuel).
- Check that fuel tank cap is correctly seated.
| WARNING | Check that fuel tank cap is correctly seated. |
Clear DME fault memory.
In the Diagnosis and Information System (DIS), go to the "Function and component selection" page.
Work through tank leakage diagnosis module. Leakage test is carried out.
If fault is recorded again in DME fault memory (tank leak detected), carry out leak test. See 16 00 510 Conducting Leak Test On Fuel Tank And Tank Ventilation System .
16 00 510 Conducting Leak Test On Fuel Tank And Tank Ventilation System
Note. The following procedure is only applicable to vehicles with the tank leak diagnosis module (DM-TL).
Select "Tank leak diagnosis module (DM-TL)" on Diagnosis and Information System (DIS).
- The leak diagnosis pump pressurizes the fuel tank and tank venting system for 30 secs.
- If pressure is required for more than 30 secs., reactivate the "Activate" button after 30 secs. in each case.
For vehicles without tank leak diagnosis module
Pressures fuel tank and tank venting system. See 16 00 100 Checking Fuel Tank And Tank Ventilation System For Leaks .
When leak-testing with a leak detector: follow manufacturer's operating instructions.
| IMPORTANT | On vehicles with tank leak diagnosis modules (DM-TL), do not work with external pressurization as the tank venting system will leak under this condition. Or use a suitable extractor system. On account of emerging fuel vapors, carry out all operations in well ventilated rooms. Observe country-specific accident prevention and occupational safety regulations. |
The leak test can be carried out with a leak detector. Possible causes may be
- Fuel tank cap leaking (check fuel cap pressure relief valve. See «16 11 130 Checking Filler Cap Pressure Relief Valve»(/bmw/x5/e70-2006-2010/remont/fuel-system/#fuel-supply-system-repair-n52-n62__16-11-130-checking-filler-cap) )
