• Check maximum value in row
one (lower window).

Tip
No engine restarts necessary!
If maximum value is less than 70%, DMTL is OK, replace the Purge Valve.
If maximum value is greater than 70%, DMTL is not OK and needs to be replaced.
If maximum value is close to 70%, rerun the test 2 more times to get a more accurate reading.

Note:
If percentage value is in question, please contact the Volkswagen Technician Helpline for further instructions.

Note:
When replacing the DMTL, ONLY replace the pump and not the whole assembly. Claims with DMTL
assemblies will be subject to warranty review and potential debit.
