What the hazard is
In the worst case scenario, the engine may not stop running when it is switched off and may continue to run until the engine breaks down.
What to do
Contact your authorised Volvo dealer to have the engine control module (ECM) software inspected and the engine oil adjusted if necessary.
Defect
The engine oil level may be above the maximum level marking. If the engine oil level is above maximum it may lead to increased engine speed.
