Angry Sti330s wastegate solenoid problem

Well I was driving home from work last night on the motorway when my engine suddenly cut power while on boost and CEL came on. Cruise light and sport light flashing etc. I pulled over straight away.
The car didn't cut out completely but I turned it off to prevent damage.

once the AA had towed me off the motorway he plugged in the code reader and it came up with P2044 turbo wastegate solenoid a range/performance

So does this mean the solenoid has failed, wastegate has jammed open or shut and engine has gone into safe mode?
Sounds like a fairly straightforward fix. Anyone have experience of this?

Car is actually still under warranty and is back at dealer for them to fix but I'd just like to try and understand the problem better myself.

Re: Sti330s wastegate solenoid problem

dealership looked at car this morning and say it is overboosting. they are contacting subaru, and ecu may need reflashed.
car is completely standard (STi 330S)

does this seem right?

Re: Sti330s wastegate solenoid problem

cold temps can affect the ecu meaning it need a reset (had it on my series mcrea when temps went below -5), but the dealer should be able to just do a reset on it so not sure why they would need to speka to suabru uk :S

dealer doesnt seem to know what its doing from how you describe it.

any specialists with a rr you can get it checked out on once they say its fixed?

Re: Sti330s wastegate solenoid problem

yeah i am slightly confused by their response
presumably they have tested the solenoid and found it is ok.
and have now come to the conclusion that the ecu is not correctly allowing for the level of boost the car is generating, and are saying an altered map is required.

puzzling, as the 330S has been around for a number of years and if this was a genuine issue it should have been identified by now.

the car is under warranty so i need to leave it in their hands. but yes there is a good garage nearby i could get to check it afterwards.

Re: Sti330s wastegate solenoid problem

So yesterday the dealer called me to say Subaru replied to their email saying there are no known issues with that ecu map and the ecu must be faulty and that it wouldn't be covered under the warranty.
They told me they didn't check the solenoid as they are sure that's not the issue.

They now say they have found a bulletin that is specific to the 330S causing the P0244 error code and it IS an ecu issue.
They got back to Subaru again and Subaru now agree its the ecu and advised a reflash to a new map will be done. However the ecu is to be sent down to Subaru for the reflash and with the long weekend coming up it won't get back till next week.

They initially gave me a temporary car but have now taken it back off me so I'm car-less for the time being.

I really don't know what to make of it all.

Re: Sti330s wastegate solenoid problem

Got a call to say car is ready so I'm heading over to pick it up.
Apparently it has been test run and all checks out ok. I'll believe that when I drive it!

Re: Sti330s wastegate solenoid problem

Well, the car does appear to be running ok with the new map/ecu - although I'm hesitant to put the foot down. Been driving around in i-mode mostly, only tried s# for a minute and it does seem to still pull well.
So far so good. No CEL lights, idles smoothly, and no smoke from the exhaust.

Re: Sti330s wastegate solenoid problem

Re: Sti330s wastegate solenoid problem

Ok, so i've got a dyno run booked for the 18th @ Hypertech in Falkirk.

What sort of power should I expect to see on the dyno assuming the car is running ok.
STi 330S. Is it power at the flywheel?
