I have a 2007 Subaru Liberty Wagon which is in perfect condition. Now am told it has the same problem! Just before I was about to sell it, or trade it in on a new car!
The Engine light remains on(amber colour) and the Cruise Control light flashes. Very annoying since I use the Cruise control a lot and now it's disabled! Subaru quoted me $3,993 to replace the secondary pump and the valves! I was shocked! Took it somewhere else and was quoted $6,000! Called a couple of independent Subaru Specialists wreckers and they quoted me around $1,100 for parts plus labour. Not sure what that brings it up to. One said 3.5K
Now I can't sell it and have decided to just trade it in for about half of what I was hoping to sell it for! If I spend money on the pumps, valves, timing belt and new brakes it will probably end up costing about and estimated $5,000! I was told this is a common issue with this model of Subaru and if you search on Google there are many with the same issue! If it isn't their loose petrol cap!
The FAULT CODE IS P1410 SEC AIR VAVLVE OPEN/SIEZED. The car drives perfectly fine at the moment. I don't know if the were just bullshitting to me because I said I wanted to sell it, or it's a genuine problem! They offered me $3,000 for the car, which is immaculate.
Does anyone know if it gets worse if not repaired? The fuel consumption is the same! Can you clear the FAULT CODE somehow?
