A4 B7 2.0TFSI boost problem.
Discussion
After recently having the car serviced with Audi (who were aware of the car being remapped) the OH and I have noticed that the car seems to be down on power. There is a lack of "oomph" when I put the pedal down, however the car seems fine in all other respects.
Naturally I assumed the map had been wiped during the service, but can't see how a diagnostic check would do so.
Ideally i'd like to see if the map is still on the car, however the garage who mapped it are looking to charge £50-60 to tell me if it's still on or not. My other thought is to check the diverter valve (prone to failure), however i'm looking to the PH audience to suggest any other options I need to consider?
Anybody else experienced similar problems, if so how was it rectified?
Thanks in advance.

Was your map a Revo? If it was and the dealer disconnected the battery, bye bye remap. You need a Revo SPS switch to get it back again, or a trip to your nearest Revo dealer.
I doubt the diverter valve would just suddenly go whilst in their care, but if you do replace it, go with the Go Faster Bits DV+. All of the VAG ones are junk. The DV+ is a complete redesign but retains the factory solenoid for reliability and convenience.
You can easily tell if the dealer wrote over your map if you have access to VCDS (aka VAG-COM).
You need to connect to the engine module, go into "Advanced ID" and check the flash count. Normally it would be 1 if it's had a remap, if it says 2 or more, your map is gone.

Many thanks for the responses guys! I am having the car looked at on Friday to see if the map is there (fingers crossed!) and then atleast that way I can start narrowing down the problem.
The remap is a superchips one, can't fault it, had it for over 10k miles now. Hoping that the problem boils down to a faulty part with a reputation for failing!
Again, thanks for the positive responses.
