Question

Answer
Simon,
Sound as though the flame trap (breather system) is blocked. Get the car to a Volvo shop so they can fix it before the front and rear seals start to leak. Lamda light could mean that service is needed to the Oxygen sensor system. In the U.S. they have done away with all the Lamda lights, so check with your local Volvo shop for needed. service.
