Before opening the injec‐ tion system high-pressure system, the fuel pressure must be reduced to residual pressure ⇒ Rep. gr. 24 ; Injection system; reducing fuel pressure . Note This function does not have to be available for all motor code let‐ ters. ♦ After the pressure has been reduced to residual pressure (ap‐ prox. 0.7 MPa = 7 bar), the connection point must be opened »immediately«. To do this place a clean cloth around the con‐ nection point. Leaking fuel creates a fire hazard. Fuel pump is activated by switching on ignition and via driver door contact switch. For reasons of safety, the power supply to the fuel pump must be interrupted ⇒ page 4 . Disconnect the voltage supply to the fuel pump • Only disconnect the battery when the ignition is switched off ⇒ Electrical system ; Rep. gr. 27 ; Battery; Disconnecting and connecting battery . ♦ By disconnecting the battery ⇒ Electrical system; Rep. gr. 27 ; Battery; Disconnecting and connecting battery . ♦ By removing the fuse for the control unit for the fuel pump - J538- ⇒ Current flow diagrams, Electrical fault finding and Fitting locations. ♦ By disconnecting the connector from the flange of the fuel pump.

S. 2.2 Safety precautions when working on ve‐ hicles with start-stop system Risk of injury as a result of automatic engine start in vehicles with start/stop system. In vehicles with the start/stop system activated (identifiable by an indication in the dash panel insert) the engine can start automat‐ ically if required. – Ensure that the start-stop system is deactivated when carrying out work on the vehicle (switch ignition off, if required switch ignition on again). 2.3 Safety precautions during road tests in which testing and measuring equipment is used Risk of accident from distraction Using testers and measuring instruments during driving operation causes distraction. There is a risk of injury if testers and measuring instruments are not secured adequately. Increased risk of injury from unsecured testers and measuring instruments must be prevented. Measuring instruments can turn into dangerous projectiles on air‐ bag activation. Testers and measuring instruments must always be secured on the rear seat using a seat belt and operated by a 2nd person from there.

Use lint- free cloths. ♦ Carefully cover or close opened components if the repair is not completed immediately. ♦ Only install clean parts: remove spare parts from their wrap‐ ping immediately before fitting. Do not use any parts which have been stored unwrapped. ♦ When the system is opened: do no use compressed air. Do not move the vehicle. ♦ Ensure that no fuel runs onto the fuel hoses. If happens, clean the hoses immediately. ♦ Protect electrical plug connections from dirt and moisture and only connect them when dry.

S. 4 Repair instructions ⇒ “4.1 General repair instructions”, page 7 ⇒ “4.2 Contact corrosion”, page 7 ⇒ “4.3 Cable routing and securing”, page 7 4.1 General repair instructions When removing and installing the parts from a partly filled fuel tank, pay attention to the following: • The fuel tank must not be more than 3 /4 full. If necessary, ex‐ tract fuel from the fuel tank ⇒ “1.3 Drain the fuel tank”, page 64 . • The extraction hose of an exhaust extraction system which is switched on, must be positioned close to the assembly open‐ ing of the fuel tank in order to extract the released fuel vapours, even before the work is commenced. If no exhaust extraction system is available, a radial fan (motor not in air flow of fan) with a delivery volume of more than 15 m 3 / h must be used. 4.2 Contact corrosion The use of unsuitable connection elements (screws, nuts, wash‐ ers, etc.) can cause contact corrosion. This is why only connection elements with a special surface coat‐ ings are fitted. Therefore, the rubber or plastic parts and the adhesives are made from electrically non-conductive materials. If there is a question mark about the suitability of parts, generally use new parts ⇒ ETKA - Electronic Catalogue of Original Parts . 4.3 Cable routing and securing Install lines of all kinds so that the original routing can be restored. To rule out mix ups and ensure the original fitting position, mark the lines before disassembly. Make photos or sketches where necessary. To avoid damage to lines, ensure sufficient clearance from all moving or hot components. Insulation or heat shield mats must be installed again in their original position.
