Lucky the Mk5 version is BLG then and not CAVD

FYI, my N75 failed again, I was able to pick it straight away however again it showed no error code on my Ross-Tech cable nor my mechanic's software. He explained however that the valve suffers a mechanical failure internally and whilst operating properly electrically they fail to carry out their intended function.
Once it was replaced it was all back to normal. As mentioned earlier in this thread I had previously changed to the piston type diverter valve and this was still operating as normal. The mech also confirmed that the N75 has a new revision number from last year onwards (previous part # was a 2006 designation) so VW have obviously identified that there's a problem and upgraded the part.

How long did your last N75 last?

I am assuming that when mine was replaced in September last year, it was done with the revised part. If it fails again, I may switch to the Forge Motorsport unit.

Mine was previously replaced in Jan 2012 so wouldn't have been the revised part.

What was the outcome? I have exactly the same problem with a 2.5 diesel TDI engine.
