My figures off the dash per tank are showing less than before the update, but so is @Chris90 who hasn't had it done. Mines in for a MOT (indy)end of the month then I'll be popping into main dealers once the weathers changed(hopefully), so I can rule out the cold weather as the possible effect.Had the update done on my A5 2.0TDI around 3 weeks ago and whilst the drive and power feels the same it's definetly doing less MPG. Used to get 480 to 520 to a tank and it now seems to have dropped to around 410 to 430. Done around 1000 miles of my usual commuting and am only managing 38mpg if I drive 'careful' where as before I didn't even think about it and would always get over 40. Going to give the dealer a call tomorrow, but I'm not holding my breath....
Graph looks identical to the ones in the A5 thread where the guy had it done.
Sorry, but its all about the delta gains, the values that were shown in Gaz's post would have a HUGE effect on how the car felt to drive udner 2600rpm. People always get strung up on peak figures. The case is totally wrong, they are only good for down the pub and doesnt reflect on real world performance of the car.
Audi clever in how they market it as says no loss in power or torque.....theres not if you look at the peak figures where the car would be sold on, however, the dyno plots ive seen, show a completely different story.
Get it on a rolling road, iff after the update the power of the car is less than it was contact Audi Uk on Facebook.

But that only provides a meaningful comparison if the car was measured on the same rolling road before the update.Compare it to before and after the update

I think the update reduced bhp, so if it's put on a rolling road before and after you can blame Audi and make them put the car back to original or give you compensation

Peak BHP means nothing.....unless you want to go brag to your mates down to pub with how high of a number you make.
The key factor to how a car drives is the volume/area of a dyno plot under the power curve. The greater it is, the faster the car, You could have 200bhp at 3000rpm, but then have nothing afterwards, or a car that makes 200bhp at 3000rpm and holds it to the redline. One will be greatly faster than the other.
Knowing how to read a dyno plot is half the battle
Torque , everyday usable torque .
Sure VAG did a better job with remapping some models but there's a whole bunch of disappointed customers with noisier , loss of drivability doing less mpg .
It was too quickly rolled out and they effectively experimented with customers cars , the egr quickly failed and they won't put the original file back on .
People are kicking themselves when they found out it was unnecessary because the recall is voluntary .
It's exellerated failure / wear of an already useless item with the emissions update .
My Golf hasn't had the update and the EGR failed last year at about 40K. My indie says he's done loads, a used car dealer he knows now replaces the EGRs on all of his 2.0tdi VAG stock before sale because he is sick of customers complaining about this fault.
My sister's 2.0tdi A3 cab went into limp yesterday, also with suspected EGR failure, bought used about a year, not sure if it's had the update.
Tell her get it blanked off and remapped

No need for data , VAG actually run out of egr's because of unpresidented demand stranding repairs at the dealers .
How easy a job is that mate?
