Random problems could relate to possible EGR sticking. I'd remove and clean EGR as the next step.

Have you cleaned (or replaced) the EGR valve yet. I mentioned this as a possibility at the end of August.
This link is possibly useful reading:- https://www.obd-codes.com/p2001
P2001 is a generic code but one of the causes can be the EGR valve sticking. The EGR is a bit of a pain to get to towards the rear of the engine. I'd try that first as it meets some of your reported diagnostic effects.

Now it looks as if you are getting somewhere. My post of August 4th did suggest that you check air hoses. I hope this will cure the problems.

on the spare parts sites 25183170 says it is not compatible with Captiva 2.2 diesel awd 135 Kw
Then I'm confused because I believe this is a widely used component on the Cruze and Orlando as well as Captiva.

Thanks Lurchy, you were very kind, but I can't open the link
No problem opening the link here in the UK. Maybe you have some setting(s) blocking it.

Read this post by Forum Member Scouse Mafia dated November 2014 under topic caption P200A OBDII Fault Code

"

Seen this code many times before? It's not just for a Chevrolet, but many other brands.

P200A is temperature too high in combustion air, this screws around with the swirl actuators, EGR and MAF, if EGR cannot control by warming up intake air, MAF gets confused.

Firstly, remove and clean EGR, also while off, clean what you can of the EGR port of the manifold. Do not disturb the solenoid of the EGR..
Second, disconnect the MAF and check the internal thermocouple has not split, this equals failure. If this is replaced, only buy Bosch. To check your MAF if ok or not, without removing, disconnect and go for a drive, note you will get the MiL lamp lighting up, but will reset once reconnected via EOBD2.

All of the above should be covered under warranty. If not EGR clean should be done every 3 years and quite easy to do as a novice / beginner. MAF even easier. Worst case is that the manifold is gunked up, which is a manifold off job, but you would be having DPF issues as well if that was gunked up. "
