      <content:encoded><![CDATA[Hello all -<br />
<br />
sorry to admit, but first time I am posting sth here is actually a request for help / hints re. a problem I am facing.<br />
<br />
My roadster wont&#039; charge.<br />
<br />
I parked the car with very little mileage left (approx. 20 mi). Tried to charge it last night, but it simply wouldn&#039;t. When I open the charge port door, it is solid white, I plug in the connector to the wall outlet (230V, 13A) in my garage. The screen says &quot;preparing to charge&quot;, but nothing further happens. The screen properly reads...<br />

      <content:encoded><![CDATA[In every Tesla Roadster PEM we have serviced to date there is evidence of failing thermal insulating material between the IGBT Inverter Transistors and Aluminum Heat Sink.  Corrective action is PEM removal and disassembly, and replacement of the thermal insulating material with an upgrade, higher quality material more suitable for automotive wide temperature application. <br />

      <content:encoded><![CDATA[Hi all, I just purchased at 2010 2.5. It came with a soft top In decent condition. Does anybody wanted to sell a carbon fiber roof or a brilliant red roof. I’m guessing these are hard to find. Any aftermarket suggestions? <br />
<br />
Also have read varying suggestions on how to maintain battery life. I only drive in about 25 a week. So should I leave it plugged in? I have a 110 charger And currently gets about 173 miles predicted to charge.Thanks in advance]]></content:encoded>

I had returned from a short drive in the rain, and after toweling off my Roadster, plugged in to charge. Charging stopped soon after, for a short time; I wasn&#039;t in the garage, but it couldn&#039;t have been more than a minute when I heard the clunk of the HPWC resuming charging. Looking at the VDS under recent alerts showed  fault #1022. Not listed on the list of fault codes....<br />

      <content:encoded><![CDATA[After doing a lot of very slow charging to recover my battery pack, I now get the BSM: V_ess too low during precharge error. It happens when trying to charge and when trying to drive. The battery is good, lowest brick is 3.97V highest is 4.00V. Pack voltage is 395V. But in the service screen the PEM has only 254V. That sounds like a problem! I&#039;m thinking a resistance between the ESS and PEM?]]></content:encoded>

I checked the WiKi and could not find any details.  Occasionally when very wet and humid I would get the BSM: Isolation fault with the contactors closed (#286) and a short drive always cleared the error and allowed me to charge.  But this was different as the warning showed up after driving a while and while warm (88F) and humid (about 80%) it was not wet or raining....<br />

Roadster number 364 flashed me a low beam or dip light warning last week as I started it. I clicked it off without really looking at it (my bad). Since that time, my headlight behavior has changed dramatically. The headlights turn on when the ignition is turned on no matter what position the switch is in, and remain on for several minutes after I pull the key out, even after locking the car. They also turn on when the car is being charged. While driving, the highbeams are on in all...<br />

I took my car in and they told me that I needed to have the ESS coolant pump replaced. In the more detailed logs in debug mode, it says something to the effect that the coolant pump isn&#039;t drawing enough current.

However, to make this useful we need to make a tool. Either something standalone, or an extension to OVMS. The protocol used by the TPMS system over K-line is not complex, but it is...<br />
