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.

Refer to Figure

-- Replace gaskets on fuel return line banjo bolts and tighten to 25 Nm.

Fuel System, Bleeding and Performing a Leak Test:

-- After installing, let the engine run at a moderate speed for a few minutes and then stop it.

NOTE:

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

-- Check Diagnostic Trouble Code (DTC) memory and erase, if necessary.

-- 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 an adaptation after replacing the high pressure pump and / or the Fuel Pressure Regulator Valve -N276-. Use a Vehicle Diagnostic Tester.

-- 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.
