Detailed Description
URO 03H103202A is an engine crankcase breather hose for the emission control and crankcase ventilation system. It is a molded replacement hose made from PA12, a material selected for resistance to splitting and cracking caused by engine heat and oil vapor. By replacing a damaged breather hose, the crankcase ventilation path can return to normal operation, helping maintain proper hydrocarbon emissions control.
This part cross-references Gates EMH224 for the same application. It is a direct-fit option for 2010 Audi Q7, 2007-2009 Audi Q7, 2008 Volkswagen Touareg, 2007 Volkswagen Touareg, and 2006-2007 Volkswagen Passat. The part number 03H103202A is also referenced as 03H 103 202A and URO-014793.
What It Helps Fix
- Cracked or split crankcase breather hose
- Oil vapor leaks in the ventilation line
- Breather system flow loss from hose deterioration
- Emission control issues related to failed crankcase ventilation
- Fitment problems caused by an incorrect replacement hose
Installation Notes
Verify the hose routing and connector style before installation. This hose is molded and includes one quick-connect fitting, so alignment with the valve cover connection and adjacent breather points should match the original layout. For best results, inspect nearby ventilation components for heat damage, oil saturation, or brittle plastic before completing the repair.
Quality Assurance
URO backs this replacement hose with a 24 Month Unlimited Mileage Warranty. The PA12 construction and molded design are intended to match OE-style fitment and withstand the conditions common in crankcase ventilation service.
