Hot Test

Yesterday was the first hot day of summer. I had the car parked in full sun for four hours, and the gauge registered 40C (104F).

On touching the handles the keyless entry did not work, on the drivers or rear passenger door. The key fob worked so I was on my way. The Keyless operation functioned perfectly afterwards.

Other than that, I was pleased with the relative cool in the car after 30 seconds with the a/c operating. I feared the Palladium would get hotter than the old Iridium, but no. Perhaps the grey seats were not as bad as the black in the 164.

The touch mode works only within 24 hours after locking the doors. For longer periods, you need to pull the handle for unlocking and open the door. I discovered that the W166 Keyless-Go is temperamental when locking the car under cold temperature, around and below the freezing point. It works only 50% of the time. No problem to unlock. Never had this problem with other MB models. Dealer could not trace a fault code on the computer.

A gaggle of MB's
Hey mate - do a search for a approved installer of the 3M crystalline (clear) window tint to cut down that heat even more - here in the US I have had several very-very happy customers including one who even had his windscreen done...

Fabbrisd1,
I do already have a tint on the side windows, and that may contribute to why the closed car was not that hot inside. But the clear film on the windscreen does have me intrigued, I presume being clear it is legal.

I had the IR reflecting glass on the W164 and was annoyed to find it is no longer available.

I was only parked for 4 hours so that would not be a problem.

So I checked the manual and failed to find any reference to 24 hours, but I did find your body acts as an aeriel.

Then it dawned on me... In those four hours, I had been undergoing nuclear scan tests and I was probably emitting enough radiation to disturb the signal. As time passed so did the radiation, so the Keyless worked again.

Maybe some radiograrher or electronics expert can confirm or destroy this theory.
