best diverter valve for r-tech stage 1 remap?

[markos]

i had the dv changed when i got my stage 1 remap done at r-tech, i think it was just the latest stock part from VW. just wondered if there were any decent upgraded diverter valves out there? and would it make much of a difference between that and the stock VW part?

if r-tech fitted it then stick with it

Most likely a G revision which is normally adequate.

Many advocate the G revision which has a rubber diaphragm which is supposed to be less prone to splitting and creating a leak than older versions. Guess what, I split a G revision so went back to the D revision which doesn't have a rubber diaphragm. Rolling road results haven't highlighted much of a difference (different days though) and it didn't throw a P0299 code either when scanned despite being split.

GFB do a DV+ product, have a read of this thread: http://www.mk5golfgti.co.uk/forum/index.php/topic,70779.150.html

Rev G is cheap and does the job. You just need to treat them as a consumable part (like tyres, brakes or the cambelt) and assume it will probably split at some point and need replacing

fair enough... they certainly know their stuff! i'll stick with what i've got for now (until it splits!)

I run the GFB DV+, which feels great and should last a lifetime. Other options include a Forge unit but these require servicing I believe.

Stick with OEM parts unless you're thinking of serious power. The stock parts are more than up to the job of stage 2+.
