hi guys retrofitted my mfsw today by changing the steering ecu and slipring with help from a few guides on here. it hasnt been coded for the multifunction controls to work yet, but i thought i could drive it around normally till i get it coded. however i have no power steering and both the steering wheel light is on and the esp light. can anyone help? could i have a faulty ecu as the one i bought is second hand? thank in advance!!!
