audis are nice - the problem you will face in Pakistan is repairing them, I was contacted via PW for helping out some workshop in Lahore which were replacing the turbos on some LHD Audi A6 they had in the shop.
When I asked for video or pictures, they showed me a horror story, the shops mechanics (all 5 plus helper) took 2 days to extract the engine from the car leaving the transmission in palce. and took apart literally everything in disconecting it. That is the wrong way to service an Audi.
The correct way was to put it into service position aka remove whole front of car (nose clip) raise on lift, shove cart under it, lower car on cart, unbolt subframe, exhaust downpipes, HVAC connections (A/C) power steering lines, electric harnesses and lift body - the whole shabbang including the suspension and driveline then is there for you to work on. It takes approximately 5 hours for such work for 1 person instead of 6x16 hours (6 peeople times 2x8 hour days).
