Dusty roads

[wycolo]

I live 1.5 miles up a dusty road. I note with interest the pair of squirrel-cage motors visible thru the rear grille. Complete lack of dust or debis filtering on these bad boys. Aaarggh!! It would seem they are blasting road dust directly into the air manifold, should they happen to turn on whilst travelling on gravel "improved roads".

Should we not install some sort of filter over the openings?? Recently during charging, one or both of these came on. Did not sould good, like out of balance or dry bearings. Roadster 2.0 #764 ~3500 miles.

TIA,
Bill

Fans do come on during charging when temps are too high; that's a good thing. With the original fans on my 2.5 this sounded like 2 hairdryers going at once, now with the upgraded fans it sounds more like a Dyson vacuum cleaner.

not having heard a dyson myself (instead having a very quiet miehle vacuum) can you tell me which of those (2 hairdryers or a dyson vacuum) is louder?

Dyson.

Bill I live on a dirt road in the summer and my Roadster gets a film of dust on it every day. If it rains it's got a coat of mud. When they replaced my fans they emptied at least 1/4" of dirt from on top of the pan in the rear of the car. It was that bad. You have the old style fans and they will replace those for you if you live in a humid climate. In your case they will fail from dust, not moisture. If your car is still under warranty then you should mention the loud sound they are making. The new fan has a shroud all around it, sealed on the bottom to the pan which helps keep a lot of dust and snow out of there. Those fans run pretty much the whole time you're driving.

Thanks for he clear description of the new fans. I live in humid (winter) and dusty (summer) spot, and got the new fans a few months ago under warranty. They are loud, but only hear them after I park. I understand the other reason for the change was snow ingress.

Roadster owner Eberhard reported problems, even with the new fans. Anything the tires stir up inside the wheel wells found its way into his PEM, charging unit, and motor, limiting charging current and impacting performance. He had his Roadster serviced one month ahead of schedule. A lot of dirt was removed from the innards, plus some tubing installed so he can blow-clean the PEM with a tire filler line as found at every gas station.

I never hear my car when charging because that happens at night. After driving the car usually makes a quiet hum. But one day when it was hot after a long-ish drive, I parked in the garage, and the noise was LOUD. I presume I was hearing the fans running full blast, where normally I'm just hearing the circulating pump.

I understand the need for the cooling system and would not have it otherwise, but the very loud noise it makes when hot is one of the minor annoyances of the car. I dislike loud noise, and the louder the worse. I like silence.

Did not know of this.

Are there other language forums as well?
