Tightening Specifications

WARNING: This page is about a different car, the 2016 Audi Q5, 2015 Audi Q5, and 2014 Audi Q5. However, it is still accessible from the selected car via links, so may be relevant.

Pay attention to tightening sequence and tightening specification, refer to Figure.

Fuel System, Bleeding and Performing a Leak Test

After installing the Fuel Pressure Sensor -G247-, let the engine run for a few minutes to bleed the fuel system and then switch the engine off.

NOTE:

The high pressure connections must "not" be opened; the fuel system bleeds itself.

-- Check the Diagnostic Trouble Code (DTC) memory.

-- Switch off ignition.

-- Carefully check the entire fuel system for leaks.

If there are leaks even though the correct tightening specification was used, replace the affected component.

-- Perform a road test where the accelerator pedal is pressed all the way down at least one time. Then check the high pressure area again for leaks.

NOTE:

If there is still air in the fuel system, the engine may switch to emergency mode during the road test. Turn off the engine and erase the DTC memory. Then continue the road test.

-- Check the DTC memory after the road test.
