Ford transit particulate problems

Image
So this week was the turn of a 72 plate transit. This time it was a particulate after sensor fault. Faulty unit! I hear you cry...that's what one of my colleagues thought when he fitted the replacement. But the fault stubbornly wouldn't go away. So the job comes to me. I test it and see I am getting CAN signals and some power. 5V to be exact. But wait, these are 12V sensors? What's going on? This stumped me. I'll admit. But not for long. I soon figured out that something was stealing power,but where? I turned to Halfords workshop. Initially, I was getting nowhere. Finally I found a fuse. Armed with this and a multimeter I could start testing.  Power to the fuse - check  Fuse not blown - check Power on the wiring after the fuse...mostly.  Following the wire through the harness was the tricky bit. Eventually I found exactly where it went. Which connectors it travelled through, and where I need to look.  So after all this. The sensor and controller was good The fuse was...

Skoda diff issues

Image
 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.
