2004 3.2 TT: TCM problem..?

[joeamo]

Recently purchase a 2004 Audi TT 3.2 with 57,000 miles Fell in love instantly, car amazing, smooth butter like shifts with the DSG trans...took it to a local independent shop (no local Audi dealer) to have the dsg fluid and filter changed as paperwork didnt verify that the service previously done. Two days after back, went to leave work, key turns everything on, but no crank of engine, and "service" indicated on dash, came back next am and key in everything fine, starts runs great, shifts great, two miles down road, trans goes into what seems like false neutral, pull over no reverse or other gears engage, turned of ignition and again no crank and service light, scanner shows 1 logged code, U0101 lost comm with TCM......get it towed to independent shop...next day start runs and drives fine, then out of blue does it again at shop, no crank and u0101 Also should mention on two occassions key in ignition tumbler rotated freely with no action, rotated around abit then key and switch worked properly... so dead in water at independent shop, not knowing if ignition switch can play into the u0101 or if im looking at a Mechatronic Unit or ? Any help appreciated

sounds like an ignition switch problem. The switch feeds power to alot of system individually. So it may be cutting power for not only the starter but the TCM intermittently.
