Hey guys. I have a 2018 C4 Cactus. During the recent heatwave, the touchscreen suddenly stopped working. I have checked fuses and had a diagnostic check done - nothing noticeable. I have disconnected the battery for sixty minutes and also removed the touchscreen unit for sixty minutes. The next step is to buy a secondhand unit and replace it myself. However, will it automatically work with my car or is it VIN specific? Would it need to be coded?
My local Citroen garage has quoted me almost £1000 for a new replacement and installation. I'd like to avoid this!
