Hi guys I drive an a6 c5 2.5 TDI 150BHP (afb) 1999 avant multirtronic/auto.
Yesterday I installed a psi tuning box folloing the instructions provided, then took her out for a test drive.
After less than 2 miles into the drive, my coil/engine light started to flash, i tried to get her back to by house and whilst turning a corner I lost all power/power steering etc.
I pulled to the side of the road and tried to re-start her and she would only crank :-(
Then I removed the tuning box and wiring and tried again, still just cranking....
Has anyone heard of this before ????
Does any one know what the problem could be ???
During the brief test drive I could tell the box alwas working well, until this happened.
