2002 V70 XC AWD Poor running, rookie, Denver thread

Also, I just received the TCV which I bought from ebay for 10 bucks and I will put it in my car tomorrow. I hope it takes care of some of the problem. Will update it here as well.

So, the mechanic changed the thermostat, changed the crank and the cam shaft sensor to an OEM one but he is still not able to fix the problem. The problem is reduced engine performance message that keeps coming out after 10-20 miles o driving. He told me straight away that he is not able to diagnose the problem and it will take him some serious time to digging under the hood to find out the root source of the problem since he has already looked into all the usual suspects and fixing them did not solve the problem.
I brought the car back from him over the weekend to drive it and see what he is talking about. The reduced engine performance message comes out after 10-20 miles of driving and also the CHECK ENGINE LIGHT came back. I did not feel any major issue with the driving performance but at this point I am really nervous about driving this car long distance since no one knows where exactly the source of the problem lies.
I went to autozone and scanned the computer with their OBD II scanner which gave me P0014 code. It says 'THE BANK 1 EXHAUST CAMSHAFT POSITION TIMING WAS ADVANCED BEYOND LIMITS FOR A PREDETERMINED PERIOD OF TIME'. I find this strange because, as I mentioned in the previous comments in this post, the mechanic changed the VVT solenoid in front of me because the old one had silicon gunk all over and two rubber gaskets instead of one which he suspected was the cause for the problem. So my question is why is this code coming up when the VVT has been changed?

Did mechanic use a new VVT solenoid?

The VVT cam could be gummed up and not working right too. Those aren't cheap.

He used an used one but showed it to me. It was pretty clean and used a new rubber gasket as well. The one in the car initially was gummed up and nasty.

ETM is a major point of failure for this model year.

Why would you say this and give false info?
ETM problems are 99-2001 PERIOD
The ONLY 2002s with ETM problems are NON turbos and just a few early cars, no XCs

I suggest YOU re-read the ETM site

That usually means the hub that it feeds is gummed up, too. Unless you know a used part came off a no code runner, you are also gambling here. I think I would go new parts on this.

Engine is probably mis-timed and will continue to give that code until a competent Volvo-familiar mechanic can re-time the camshaft timing for you.

Mechanics are not dishonest any more than anyone else, it just doesn't pay to stay expert on cars that are 2x typical life use. That's the anomaly of the Volvo and their owners.

I'll give the mechanic kudos for telling you up front it's a lot of hours to diagnose a difficult fault.

Mike is right as usual, I bet the VVT. Hubs are mistimed

The mechanic suspected that the VVT hub was mistimed and used that special tool to time it. He showed the special volvo tool and did adjust it to make sure it's correctly placed. So I'm guessing that's what you mean by VVT timing?
That was done the same day he changed all the other parts like the camshaft sensor and the crank sensor etc but the reduced engine performance still shows up.
The funny thing is that I don't experience any change in cars performance even when the reduced engine performance is on. No limp mode or anything of that sort. If you remember, when I started this post, I said the car went to limp mode but after he changed the thermostat, crank sensor and all that the limp mode is gone but the reduced engine performance is still there.

I guess it's called the VVT camshaft fixture tool. He used that but it wasn't the problem.
