Hi

I own a VW Passat B6, 4motion, 2006 and I was told by friend that my ECU could be updated to a higher SW. Although he didn't seem to be able tell me what that gives. Updated SW would be according to his words from 9674 to 9970.

Could anyone tell me what would be the outcome of it? I asked local VW dealer and they said they only upgrade if there is a problem with car. I don't have a problem. But I guess it would give something, because there would not be an upgrade just for fun. Oh, and just to have newer SW is also a good thing, just like with program and VCDS versions! :)

You cannot update with VCDS your ECU. You need VAS or any interface capable to do that. Because your car is not Euro5 compliant, you cannot update with pass-thru device.

Is the latest software always better?? I have updated my Iphone a few times and it definitely worked alot better running the older software.

I personally think that most software updates just loosen the parameters to allow for unforeseen wear.
For example, a few years ago certain V6 mercs were wearing the sprockets away on the balance shaft. Mercedes released a software update to try and fix the issue. I assume this update allowed the camshafts to be further out of time than was allowed for in the original calibration.

Im sure I have also read a Vauxhall TSB stating that they purposely reduced fueling at low revs (low end torque) in 1 of their software updates (1.9cdti). I will dig out the TSB if your interested.

I say dont fix it unless its broken, you may make it worse.

Someone may prove me wrong but this is how I see it.

You should be able flash older software versions using ODIS engineering.
