1. Manufacturer's Corporate Name: Volvo Cars of North America, LLC
2. Description of efect Component Name: PCV OH Trap Diaphragm and Crankcase Ventilation Hose The oil trap diaphragm regulates crankcase pressure and mediates the flow of crankcase vapors into the engine air intake system. The crankcase ventilation hose provides a return path to the t'n, system, via the crankcase PCV oil trap, for vapor from under the valve cover. The oil trap diaphragm membrane (certain MY04-08 vehicles) and crankcase ventilation hose (certain MY05-08 vehicles) materials may degrade and crack after long-term exposure to the crankcase environment. 3.

3 of 4 Volvo Cars of North America, LLC - EDIR No. 07007D01C 2009-02-035. Description of Failure Impact

No impact on drivability. The Check Engine (MIL) light may illuminate with DTC ECM-250A (P0171) (N/A engines) or 262A (P0171) and/or 261 A (P1171) (MY04 Turbo engine) or 21CC (P2187) and/or 21AC (P2177) (MY05-> Turbo engines) (long-term fuel trim) and there may be unexpected noise coming from the engine.

6. Available Emissions Data For model year 2004 there is no impact on evaporative emissions. For affected MY05-08 vehicles certified to PZEV standards, worst case scenario crankcase emissions, with 100% disconnected crankcase ventilation hose, were 532 mg/test in a 2-day test. These results exceed CARB allowable 2-day test levels [0.35 g/test (cert + low & high mileage in-use test)].
For affected MY05-08 vehicles certified to LEV II standards, worst case scenario crankcase emissions, with 100% disconnected crankcase ventilation hose, were 68 mg/text in a 2d test. These results do not exceed GARB allowable 2-day test levels for model year 2006 and earlier [1.14 g/test (cert + low & high mileage in-use test, including phase-in factor of 1.75)]
Volvo considered and tested a disconnected crankcase ventilation hose as worst-case, 100% crack (leakage). Technical material analysis confirms there is variation, but average cracks (leakage) are between 30 and 50% at time of diagnosis and repair. This lower percentage reduces the PCV evaporative emission contribution to a correspondingly smaller figure.

7. Anticipated Manufacturer Follow-up For affected MY05-08 vehicles certified to PZEV standards, Volvo voluntarily decided to perform Voluntary Emission Recall 202to upgrade the concerned cars with an improved oil trap and crankcase ventilation hose. Beginning on November 6, Volvo began mailing customers to inform them of their eligibility under this emission recall program. Volvo has marked all eligible vehicles in the warranty system.
For affected MY04-08 vehicles certified to LEV II standards, Volvo has voluntarily decided to offer Extended Warranty 205to extend the vehicle emission warranty to 10 years or 120,000 miles, whichever comes first, to provide, at no cost to the customer, based upon valid customer complaint, an improved oil trap and crankcase ventilation hose. Covered customers who have already paid to have their cars repaired due to this condition within the extended warranty period may be eligible for a refund.
Volvo will conduct a mailing to inform customers of their eligibility under this extended warranty program and mark vehicles in the warranty system to indicate eligibility.
