From reading on here there are a few posts that say this is down to the turbo actuator arms getting gummed and sticking a bit so when you first start it flashes up with engine system fault error and goes off!

You can free them off and oil them so this goes away. There are some write ups aswell if you search turbo actuator but no visual guides.

Bumping this thread, as it certainly helped me. Had this issue last week. Fault came up a couple of times but when my mechanic used a code reader, there was nothing obvious.

New battery fitted, then having read this particular thread a check on the hoses. Sure enough, one had split. Replaced and all good. Other then while he had it she was treated to an oil and filter change so my bill wasn't as small as it could have been.
