After filling tires when cold to the specified amounts, I have noticed that when monitoring the pressures the right side always jumps 2psi higher than the left. This happens when i refill, dealer refills. Is this a fault with the TPMS or has anyone else had issues like this. Please chime in and let me know. TIA.

1) Next time you notice this STOP and switch wheel/tire combo side to side. Then let us know if the issue travels to the other side.

2) You are not telling us if you turn one way more than the other way during your drive.

3) You are not telling us your direction of travel: E - W, W-E, etc.

4) Does this happen mostly after you get into your parked car.

This occurs with mixed driving of city and highway. With turning occuring to both left and right side equally if not more left. direction of travel also varies across the board. and this happens from cold start. first thing in the morning to stop and go ... throughout the day. didnt know if there is more resistance to the right side of the vehicle and that is why the pressures are increasing more on that side. and with switching tires from side to side then you would have an issue with tire direction would you not.??

Did you put on directional tires?

I would have to check the tires... They are the stock scorpions that came on the glk.

Interesting you mention this. I have noticed the same thing. I keep my tires at 35 in the front and 38 in the rear. The left side drops a few PSI every few months or so, while the right side of the car is totally fine.

Also, I just brought in my car for service and got a loaner GLK. The left rear was at 25! and left front was at 28, while the right side of the car was normal.

Weird!
