– Connect fuel system tester - KLI 9210- to vehicle battery.
– Remove rear right wheel housing liner.
– Clamp off hose between fuel system diagnostic pump - V144-

⇒ Item 8 (page 213)

and air filter

⇒ Item 7 (page 213)

to

-arrow-.

– Set valve -D- to “Test”.
– Observe pressure gauge -C- and flow meter -E-. When the

throughput quantity decreases and the pressure increases to

10 in. H2O (25 mbar), the fuel system is filled.

– Once pressure has stabilised, set valve -D- to “Hold”.
• After 5 minutes the pressure must remain at or above 8 in.

H2O (20 mbar).

– If the pressure no longer drops, renew fuel system diagnostic

pump - V144- .

If the pressure is not held for at least 5 minutes or does not build

up, localise leak as follows:
– Fill fuel system with smoke, set valve -D- again to “Test” for

this.

– While fuel system is being filled, press button -I- for smoke

generator for approx. one minute.

The fuel system is now pressurised and filled with smoke.
– Check whether smoke escapes from any fuel system line or

hose. Also check fuel tank cap.

Note

♦

Light up the components and hoses with a strong floodlight. In

the floodlight, smoke is more visible.

♦

For leak detection in accessible areas, also use ultrasonic de‐

tector or commercially available leak detecting spray.

♦

Depending on how long the fault finding takes, it may be nec‐

essary to press the smoke generator button from time to time.

This ensures that sufficient smoke is present in the fuel sys‐

tem.

♦

To inspect flanges for fuel pump and fuel filter, open assembly

opening in vehicle interior.

– Renew leaking hoses or components.
After completing work, perform guided function “Checking fuel

tank breather system for leaks” using ⇒ Vehicle diagnostic tester.
