All,

I know this has been discussed a couple of times elsewhere, but the threads appear to be a mixture of TFSI and TSI related comments. So, for clarity, I thought I would start a new thread relating to failure of the diverter valve on my MY11 / 60 plate vRS TSI. (On about 30k miles).

06F 145 710 G: This is the failed valve which has the split diaphram as in the photo attached. (Apologies for the poor phone quality).

06H 145 710 D: This is the new valve that's been fitted and is the updated spring / piston type many of you will be familiar with.

So, for those not familiar, the background here is that the car wasn't pulling as smoothly for quite some time, and then seemed to loose boost pressure. VCDS showed up the following:

000665 - Boost Pressure Regulation: Control Range Not Reached

P0299 - 000 - - - Intermittent

When I looked on here and other wise places on the web things mostly pointed towards the TFSI engine having the diaphram type DV. However, with thanks to the notes from Rob_e it sounded like the earlier TSI engines may have been fitted with this too. So, I can confirm the car is running back to normal, smiles are back on my face and here's another added to the list of TSI engines with a DV that apparently should've been updated already...

Part was about 55 pounds and was in stock at TPS... I chose this route vs. warranty for speed and simplicity.

Mines is on its way from TPS should be here tomorrow as i too have a funny feeling it has split in my car, isnt as smooth as it was and whistles quite badly.

£37.97+vat hopefully fitted over the weekend i too chose to buy my own instead of a warranty claim.

I'm going back to G from D lol. I Have seen graphs where the diaphragm version holds boost better, they also make less noise with the intake fitted.

I'll try it anyway

Is your car remapped?
