Hello, hoping someone can help me.
I've got a 2013 i30 1.6 crdi done nearly 80k miles.
While driving everything is fine but after a few miles I lose all turbo boost
No errors on dash and engine sounds fine.
If I turn ignition off then back on I will get boost back like normal
But after a few miles will lose all turbo boost again.

I'm assuming it's something to do with the wastegate? But not sure how to
Diagnose or isolate the issue?
Any advice or help would be greatly appreciated.

Thanks.

Does the engine limit revs to 3000rpm?

If it does then the car is in limp home mode and needs to be connected to obd reader to see what causes it. Even if the check engine light is not on there can be fault codes which should be read.
