2001 Volvo S40 ProblemsRight Front Engine Mount May Wear and Cause Vibration at Idle
The right front engine mount wears out prematurely, causing engine vibration at idle.
The fuel pressure regulator can leak and cause a hard start condition, without any faults recorded in the engine computer.
The turbocharger return pipe seal may develop an oil leak. The leak can begin very small, but will eventually progress into a large leak. Our technicians recommend having this repaired at first signs of leakage.
2001 Volvo S40 QuestionsI have a new radiator in my 2001 S40. How much trans. fluid to add at dip stick? (1 answer)

We're reading code P0237 on our Volvo. We replace the boost sensor and reset the check engine light. Light hasn't come back but the code is still popping up. Can't pass the emissions check with the code. Any ideas on what to check next?
