October 22, 20187 yr Outback, 2008 diesel, complete with P0409 I've had the EGR valve out and couldn't find the carb cleaner. M'sahib recommended oven cleaner and you know what, there's a lovely smell that follows you around! Got tons of carbon out of the assembly but not all of it. I have no clue if it's working correctly but I do know what has to happen next. Take it out again and get the back off - tamper torq bolts and I didn't have the kit at the time. Dismantle and soak until it's like new. Squirt loads of carb cleaner down the J pipe and some into the inlet on the other side of the valve too. Q is, how do you test it to be working? As it's electric and not pneumatic, I imagine i'd have to put 12 volts across two terminals and the valve should open. But here's where I get lost. Any pointers? ta, David
