Strange TPMS issue
I currently own a 2008 w204 C300 Sport
I have checked and adjusted all air pressures.
The Yellow tpms light flashing during startups, turns solid after a minute or so. The dash information displays 0 messages, however once a week the RED TPMS disabled warning will come up. I will RESET values, however Yellow TPMS indicator stays on. I've tried this reset procedure many times.
I have a Snap-On Apollo D8 Scan Tool & Snap-On TPMS4
The Apollo was showing me a code D165 " Communication with tire pressure sensor 4 has a malfunction" also the data is showing the Right Rear sensor was not active, -58 deg temp, 0 pressure readings.
-I went ahead and changed out the Right Rear sensor to an aftermarket oe replacement sensor. Cleared the TPMS codes with scanner, drove 10 miles, TPMS Light back on. Still no reading from RIGHT REAR. Then checked TPMS4 tool, ALL sensors are picked up by TPMS4.
-I then swapped RIGHT REAR & RIGHT FRONT wheels, cleared code, drove 10 miles... Light back on, & still NO READING from RIGHT REAR.
I feel it might be a transmitter issue, however having it only affect one wheel, I feel is strange.
I've searched for similar problems online, if this post is redundant, I will delete it if necessary.
Thanks in advance.




Everything is pointing back at the module... check connector for any corrosion issue.
