Can the new B7 Passat 125TDI be tuned

[cru22z]

As the title say.
I was told the new B7 Passat is anti-tune therefor can't be flashed using handheld tune. Can you beg to differ

[kamold]

Most likely yes, it cannot be flashed direct via the ODBII port.
Requires a 'bench' flash.
So you need to actually visit a tuner, you can't order something like a Bluefin (as far as I am aware at this time.)

Can't do it with a hand held. We have done them with the Oettinger upgrade, no problems whatsoever.

Yep, just to chime in, I can confirm that these are a bench tune only. ECU needs to be removed, disassembled, tune flashed directly to the PCB, reassembled and refit to the car. It's not hard to do (for someone that knows what they are doing), and the gains on these things make it well worthwhile.

Would the bench tune void warranty?

Ok so much did the whole tune cost?
Also what are the warranty like? Would vw detect the tune during service?

Like all modifications to a vehicle (including wheels, window tint, bluetooth kits, towbars etc) it could possible effect part of your manufacturers warranty. Bench tuning is no different to port flashing in regards to warranty, both times you are modifying the code inside your ECU.

VW may be able to detect at service - yes. Cost - send an email to info@oettinger.com.au with your details. Warranty? Like all registered & insured tuners on these forums, they will cover some form of warranty. Oettinger have their own:
