I mean the Turbosmart and the GFB items operated the same (while the GFB DV+ was working) as there's not much to it, they are both operated by the car ECU and both make a better seal than the OEM.

As the diverter valve requires quite a lot of removing the bash plate cover, a front sway bar and removing a coolant pipe from the water pump resulting in a full coolant flush, ideally a car lift, you'd want the better lasting product in it the first time so you aren't throwing money down the drain trying to access the diverter valve to repair/replace it.

Once you have access to the diverter valve, the major difference is the Turbosmart product used 3 bolts that fit into the turbo perfectly, and it came with the right plug that connects to the BMW wiring.
The DV+ is a similar procedure, except you then pull apart the plastic OEM diverter valve, modify it, then put it back on to the turbo.
Even if the DV+ part doesn't fail, the plastic OEM diverter valve is still just that, plastic and WILL eventually fail again.

My advice is just to get the Turbosmart product installed from the beginning and have the OEM diverter valve sitting in the garage as a spare until it's time to put the car back to stock to sell the car. And then sell the Turbosmart product or take it with you on to your next car.

The Turbosmart product is made of billet aluminum. It even just feels like a well-enginered part.

I don't want to start and argument, but I think what you're saying is a little unfair...

To start with, your complaint with the GFB DV+ is the first I've heard of, and similarly this is also the first time I've heard of the Turbosmart alternative.

You suggest that to replace the diverter valve requires "[removing the] front sway bar and removing a coolant pipe from the water pump resulting in a full coolant flush", but this is simply untrue. There are several videos and forum posts that show this is not necessary. It is necessary to remove the stiffening plate, and though not necessary, unbolting the water pump but not disconnecting any pipes helps with access.

The DV+ itself re-uses the solenoid portion of the factory diverter valve, which itself has no moving parts. Everything else, including all moving parts, are replaced with machined metal parts. Three replacement screws are supplied and they too fit into the turbo perfectly. It also has the same plug because the solenoid is factory... therefore it just plugs in.

I don't want to suggest that fitting the DV+ is easy; it's a royal pain, but that's not the fault of the product, and I wonder if your mechanic did something wrong when installing the DV+ which caused it to fail.

The Turbosmart option is probably great, and since I've not seen it or installed it myself I'm not qualified to comment, but I feel that you're unfairly bashing the DV+ product... no-one else seems to have had anything but praise for it... myself included.
