I am having endless problems with my 2008 Cross Polo's electrics and turbo
The lastest my mechanic says is that my ECU is gone and needs to be remapped, but upon further research, it seems a lot of people online say it might just be the wiring and earthing of the ECU.
These are the problems I'm facing
- The engine loses power and judders when accelerating. The fault normally goes away if the ignition is turned off and the engine is cooled down before restarting. The diagnostic says there is a communication error between the ECU and turbo. The wastegate has been adjusted.
- The ABS light is on, the diagnostic says it is not getting power from both wheels sensors (l/r) but a few different mechanics say there's nothing wrong with both sensors or their wiring and could be an issue with the ABS pump or control unit.
- The speedometer isn't working
I haven't had my battery tested, but it wasn't replaced too long ago.
Would appreciate anyone's help here. This has a few auto electricians and mechanics stumped.
