Hi,

there is a conversation at the moment in german board(s).
The basic idea is to use the N249 wires, a TFSI diverter valve and an adaptor like 06F145751 to have a electric diverter valve without vacuum lines.
Its faster and better and bla....okay!

one guy is running this for year(s).
the ecu / driver behind N249 is capable to support the power of the tfsi/med9 diverter falve.
i had a look into LDUVST and couldnt find any downsides.

BUT i am not that familiar with the diagrams in the FR like you are

so the question is, are there any hidden hitch or is this working on me7.5?

regards

I would like to do this. In fact I'd be the guinea pig. What is the part number for the TFSI valve?

I would like to do this as well, probably should replace my stock dv anyhow.

Good FR information about the N249 can be found here.

I ordered the valve off ebay...... should be here in a few weeks.

http://www.ebay.ca/itm/281325968374?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

I'm now looking for a good price on the adaptor. I'll update when I find a reasonable source.

Is this a fake item?

The adaptor 06F145751 is around 63€ in germany... thats crazy.

Found one for a reasonable price, and shipping. Most all of the performance parts suppliers in the US want between $25-$50 to ship a small, lightweight parcel to Canada. These companies won't be getting my business. Get real on the shipping charges, or don't offer shipping to Canada.  Angry

For a shiny, brand new adapter Grin:

Can't wait to get this on the car. My logs are showing the effects of using manifold pressure to activate my stock diverter valve instead of ECU control via N249. I plan to use this new valve setup close to throttle valve inlet when I finally get around to installing my front mount IC. This way cooled air gets recirculated instead of hot. In the meantime, it's going in the stock TIP location. Will update with pictures when installed.

FWIW, if you need some stuff sent to Canadia, just LMK. Happy to accept/rebox/post it to you.

My next question is what current does the new diverter valve draw vs the stock n249. I'll have to measure resistance of the new valve coil when it arrives. If the new valve is very low impedance, I might rig up a relay.

A relay's gonna take days to respond compared to the ECU..

You reckon the "ON" time is fast and short enough that an impedance mismatch won't bother the driver circuit?
