New to me 2008 C5 X7 2.0 HDI VTR+
Fault code: 98D3
I gather this suggests a short circuit to +ve.
(Use of the word 'coherence' suggests to me a mistranslation from French? What should it be?)
So, where to look?
Could this be a defective sensor elsewhere? (I've replaced the rear right sensor).
Could the fault be in the loom? If so is there a common point of failure?
Could the relevant ECU (next to spare wheel) be at fault?
I'd be grateful for some pointers.
