TPMS question
I've recently installed C6 18-19 wheels with new Schrader #28006 sensors on my 00 C5 and I'm having issues getting them to function.
After reading multiple posts with a lot of great info I'm still having no luck.
FYI the original wheels/sensors worked fine prior to this conversion.
I'm wondering if the past owner had switched the system over to a newer style and this could be the issue. The car had no FOBs when I purchased it so I got one on eBay and it programmed fine.
Is there a chance that this system could have been upgraded since the FOB works fine, or do I just need to get a larger magnet and try again?
All help and thoughts appreciated.
Thanks for the info as the magnet I had was just too weak. I was nervous because as a courtesy the dealer tried to calibrate them when I was in for an oil change recently so I thought there may be something more significantly wrong but evidently not.
