Should a car be ok after a turbo has been replaced?

[Astra123]

I recently bought an Astra Ecoflex 1.6CDTI with around 60K on the clock. After about a week, the engine light came on and the car was intermittently showing loss of power.

The garage I bought it from have arranged for the turbo to be replaced.

Should this sort out the problem or is this going to be a reoccurring problem?

If the turbo was the problem, then fixing it should fix the problem. If the problem isn't fixed, don't let them fob you off.

Not sure a new turbo if the answer here. If it was knackered it would be knackered, not occasionally knackered.

There's several things that could cause power loss from a blocked or worn EGR to a blocked DPF, failed MAP sensor, boost leaks, actuator issues or yes, possibly the turbo itself. You assume they've investigated the issue, traced it to the turbo and having confirmed it as faulty, are now replacing it and thus following replacement of a faulty part, it may be fine again or there my be underlying issues that require further investigation. To be honest there's no hard and fast answer here, it really comes down to how thorough and competent the garage is at a) reaching the correct diagnosis and b) carrying out the required remedial work to resolve the issue.

Impossible to diagnose without knowing the fault codes that are causing the EML to come on. Could be a multitude of things causing loss of power.

Agreed.
Their job is to fix the power loss problem.
I’d not worry too much about what the issue is / was. Leave that to them.

At this point you still have the option to reject the car. If it was me, with a car facing unknown but potentially serious engine problems, that's what I'd do.
