Hey folks,

on sunday night my poor Octy VRS suffered its first problem in my ownership and now im mega confused!

i took the better half out for our anniversary and left her to go to her night shift and drove home (35mile trip) the car drove fine and boosted as per usual until.......7miles from home i felt what id describe as a "miss" then coming off of a roundabout the car felt exactly like it did premap.

we have put the car on our diag machines at work and no faults can be found? except......in the measured value section the car is asking for 0.3bar and its actually getting 1.1bar at idle?!

we have changed the MAP sensor or boost thrust sensor to some people and i have tried a new MAF sensor and still the exact same performance from the car and the diag machine

has anyone else got any ideas or thoughts on what this might be as we are now scratching our heads?

Split diverter valve?

Are they bad for going?

best to uprate it

It's a well known problem with the tfsi once remapped. A revised version of this part was used from around about the time the tsi engine and the facelift octy came out.

The newer D type are plungers and do not split . Well Awesome told me they had never seen one "Go"

Your Revo agent should have recommended that this part be replaced before or soon after going to stage 1.

well guys.....

good news! the new diverter fixed it the old one had a split in the orange seal and it was actually slightly cracked! the car now actually seems to respond a bit better as well!

replaced it with a standard audi one for just now but end of month ill buy a Forge item

Appreciate all the help gents!

No need for the forge DV, the D revision is more than capable for the job

Yes as Harry says the new one is fine, when mine went I was going to have a forge one, they said we could sell you one but a waste of money they are no better, just look bling!
