Another fault on my V10-
work done: replaced both batteries, changed front air-springs (both sides).
After the car came back from the mechanic, drove fine the first day; did not drive for two days. On the third day, pre-start voltage was 12.7V and the "Fault Running Gear" returned.
While driving, sudden loss of power, connected vag-com, both turbo controllers were showing fault 18360 and 18361 (at addresses 1 and 11). Cleared faults, ran fine but after some time, faults returned. Three times. Came home, parked.
Note: mechanic said he removed the *front* battery first. Told him he should have done the rear but he showed me relevant info in ELSA which said to remove rear first.
Detailed inspection reveals
1. Mechanic (at dealership no less!) managed to remove front right air-spring without taking out wiper arms. As a result:
2. ECU was sitting very lose (one rubber holder on left side missing) and all the wiring was also sitting lose (not in it's clips, the big sockets were lose too).
3. Some other fault codes, many are "normal"--i.e. due to known issues like the door handle buttons being faulty and rear parking aid sensor wiring knocked out (due to reversing in a lamp post), no TV tuner but some are suspicious. Copy-paste of the fault codes below (sorry for not posting auto-scan as still using third-party cable with registered Ross-Tech VCDS-Lite).

Other information which might help:
1. With old batteries, if the voltage dipped below 12.5, turbocharger control module #2 fault (at address line 11) would come but once cleared, would not return if battery didn't dip below 12.5, and certainly not while driving.
2. The chances of control modules being faulty are slim as they worked fine before and always both suddenly fail.
3. I was suspecting lose connection in ECU as it's all lying lose under the plenum cover but only right-hand side (master) ECU is like this, so the fault should only come for controller #1, not #2 as well simultaneously.
4. Air suspension "Control Position Not Learnt" fault went away after changing batteries and struts and calibrating but came back on third day (didn't drive for two days). I didn't calibrate with VCDS but raised to max and lowered to min levels and drove for a while, fault didn't go away. Makes me think of a lose battery/ electric supply connection than anything else as suspension works fine and raises and lowers perfectly.
5. The terminal 30 warnings (and the fact mechanic removed front battery first) makes me suspicious also.
Will ask him to fix all the silly ECU stuff he's done and also check all fuses and connections (esp. battery connection under the seat and associated fuses, relays, etc.). Also will ask him to grease the turbo link rods and check them with the car running.
Any suggestion: both (educated) guesses and personal experience would me much appreciated.
