Skoda diff issues

 We had a lovely Skoda Kodiaq come in complaining that they had lots of lights on the dash. I was given this to have a look. When he plugged it in there was over 40 faults stored! Most of these were communications faults and low voltage faults. After some investigation it was found that the main fault was in the Haldex control module. Initial inspection of the system didn't reveal any obvious damage. On closer inspection of the haldex control module we discovered that the seal had failed and that water had gotten into the module. This had caused a cascade failure across all the other systems connected to it. We replaced the module and adapted it to the vehicle. While we were there we carried out a haldex system service. Cleaned out the filter and replaced the oil and seals. Test drive to confirm fix and handed back to customer.
