New here so hopw I am in the right p;ace.
Had to change a duff chip in my speedo and all worked well bc I downloaded the data first and reloaded the new chip
All worked well until the car just packed up completely when I tried to start it one day. The Immo kicked in and was difficult to resolve.
Now finally worked out a way to get it going but need to stop it from keep on happening. when it happens the speedo goes all the way around the clock as do the fuel and temp and the signs are all on the dash
to solve it I have to disconnect eh battery and short the terminals together and hold for 30 seconds. That clears it and the car then starts. However I then have to plug in VSDS and clear all faults and get the power steering back for example but as soon as it happens again I loose it all again.
Any ideas on how to stop this from reoccurring?
Any suggestions appreciated
