Hi everyone,i just bought a used B6 A4 with problems,wish i did more research first.It's 2002 1.8T FWD tiptronic{guess that means CVT,could be wrong}Ok,here we go.The car hard starts then shuts off.I was told before the car was parked for about a year it was smoking badly and might be the turbo went bad.now i looked at the fuel pump and it has some gunky build up on it. This gas has been in there for over a year i suppose. Their are no engine lights on in the car and it passes the systems test.I checked for codes and got the following, p0722; p1793; p1857; p1775;p1757. I called an audi dealership and spoke to a tech that works there and he told me those codes point to a bad TCM.I live in the caribbean and a new TCM here is $14000+ excluding labour. Then i gots to buy a new turbo,new fuel pump etc. Can i swap out this motor for another 1.8T motor and gearbox.i can get from the UK where they are right hand drive.If i do change this engine and transmission,would i also have to change the instrument cluster key etc? or what would you all suggest?Please help as i really need some further info from knowledgable ppl. Thanks.

 

p0722- output speed sensor circuit no signal
p1793- output speed sensor 2 circuit no signal
p1857- load signal error message from engine control
p1775- hydraulic pressure sensor 1 adaptation at limit
p1757- don't know this one.
