Coming off a roundabout earlier I noticed the car was down on power, albeit still running smoothly. Looking on VCDS I have the following:

- Is the '-002' on the P0299 significant? Does it signify which bank for example?
- Do I have seperate low boost errors on both ECUs or does the error in (presumably) ECU II copy across to ECU I?
- Related to the above, is there any physical link (i,e, a plenum) between the left and right turbos? If the two banks are entirely separate then a simultaneous loss of boost in both could only be something like the diverter valves? If there is a common intake plenum then it could be either side. Alternatively it might only be one bank but two messages.
Thanks!
