Professional Parts Sweden is the manufacturer- as you correctly pointed out in a post earlier in this thread:
“That's an aftermarket replacement part and quality of most of those are suspect.”

FINALLY solved this problem. I took the car to a Volvo specialist shop where they took a look at it with VIDA. Confirmed to be an intermittent problem with the exhaust VVT caused by a bad VVT hub, bad solenoid or wiring fault. They couldn’t narrow it down any further. So I ordered a new hub and ...

My 88 745 wagon has a very annoying rattle coming from the back end whenever I drive over any slightly bumpy pavement. With the vehicle weight and off the wheels I have smacked, wiggled and twisted everything including the suspension bushings, but everything is tight. But if I thump the bottom of ...

Thank you for that, Abscate. Looks like a trip to the Volvo dealer next week. Its a 3 hour drive from me but so be it. I've spent enough time on this already! Will post the results then. Just want this fixed so I can sell both vehicles and buy a used V70.

Well, no joy yet on solving this problem. My next plan is to dump some Seafoam in and then change the oil & filter. The oil passages to the solenoid my be gummed up. Also I discovered my code reader (don't know a lot about how they work) has a “Freeze Frame” function which takes a snapshot of engine ...

First, A BIG THANK YOU is due to all the forum users that contribute to this knowledge base. I have learned tons of stuff enabling me to do almost all the work on my two cars myself, saving probably thousands.
Back to my problem: I just finished dismantling things yet again to try and determine ...

Haha...there's a “Volvo only” junkyard 200km from me...NYC's about 4800 km...

How did you determine that the used one is working correctly?

I tested it with a 12v battery before and after installation.

Hell no! First off, that would be treating the symptoms not fixing the cause. Second off, changing the position of the cam will not change its response time...

Ok, I ...

Been away for a couple of months and just attempted to solve this P0027 code problem. Installed a working used solenoid but the code persists. The shop where I buy parts has gone out of business but I talked to their mechanic who suggested loosening the timing belt and moving the exhaust cam one ...

Thanks for the replies. The code had been popping up occasionally over the last 8 months or so. Took the solenoid off a couple of times, tested and cleaned it. But over the last month each time I reset the code it came back within 10 km or so. I recently changed the oil filter and used Quaker State ...
