V6 TDIs - some limited to 2500rpm in neutral

['WG']

Apparently, some V6 TDIs are limited to 2500rpm in neutral.

I've heard of two examples so far, an A5 3.0TDI "auto" (MYreg unknown) and an A6 2.7TDI Avant multitronic, MY09reg.

Does anyone know whether this is a standard factory setup? If so, which models and MYreg's are covered?

If not factory set, then presumably it's been done somehow via aftermarket software, such as VCDS.
If so, exactly how is this done and again on which models and MYreg's is this possible?

Perhaps it's just the multitronics, ie non-quattro FWDs?

It is on my C7 but no idea if it was on my C6.

Factory set on my A6 2.7TDI Avant multitronic, MY09reg

Scott K - I know little about the BiTDIs, is yours a V6 Quattro? Presumably, unchipped?

royclark - "Factory set" -- that's interesting.

There must be a common denominator, I hope it can be found...

press and hold the esp button to turn off both esp and asr. now you can rev it all the way. you cant rev above 2500 to save you trashing the tramsmission by revving it flat out then slipping it into gear for a fast start.

[Scott K]

Yes, all the 3.0 are V6 and all the higher powered cars are quattros on the C7. Mine is standard as well-still under warranty! I only found out about it when someone mentioned it on the forum, so tried it a couple of weeks ago.

Scott K - great, so now we know it's not just multitronics.

I wonder if it's related to vintage? For example MY09 V6 TDIs onwards?

My MY55 definitely isn't restricted ...

My 2008 3.0 was, my 2009 A3 1.9 is, my 2015 A4 is.

My 2008 3.0 was, my 2009 A3 1.9 is, my 2015 A4 is.

So, it would not appear to be a Euro V compliance.

We'll probably never know why some do and some don't.
