P0244 error code

[markswlondon]

Feel sick as a dog.... 4 times back to dealer. At first the code was p0299 (low turbo boost). The last time they looked at it they replaced the turbo... I get it back tonight and all is good for 80 minutes... Then I get limp mode again. New code now reads p0244 ( turbo solenoid performance)..
I'm at the end of my teather!!

Thanks... I've had a couple of beers and calmed down a bit... Only a bit !

I am considering and probably will ask for my money back tomorrow. They've had ample time to rectify. It might be something small but I am worried this list of problems could continue for months ( most worryingly, after any warranty period).

Thank you again for your comments and feedback. I must say, everyone on here have been great in offering ideas and comments.
