re: internal control module error

[brent 3045]

just checked my fault codes through vagcom and got these fault codes

awd

00526- brake light switch implausible signal

65535- internal control module error

are these connected in any way? and could the brake light switch be causing the ecu memory error?

just looked under the rear n/s next to the driveshaft and there is no earth cable for the haldex system. anyone with a diagram or pictures to show me where to rewire it from and to?
no cable hanging down anywhere neither
