DIAGNOSIS

1.  TRACTIVE PROBLEMS

Before a boost pressure curve is plotted, an
acceleration test must be performed.
For the acceleration test see Group 2 of the
workshop instructions, main group 1
“Diagnosis”.

Note:
Checking the boost pressure will in general only
make sense after the vehicle has covered at
least 20,000 km.

The test sheets are available through the DAF
organisation.
If no test sheet is available for the engine type in
question, you may compare the engine with a
different engine having the same specifications,
as long as the latter is in good condition.

To plot a boost pressure curve, see main group
“Inlet/exhaust system”.
