Thanks Thanks very much for the reply. How much they charge in US for replacing the boards in US? They are charging 10K here in HK. It seems very expensive for just swapping some of the boards....

I have a 2011 Roadster and I am going to upgrade 3.0 battery. Tesla asked me to replace the PEM with the 3.0 battery upgrade. My PEM is working fine. Do anyone know that whether it is just recommendation, or it is a must for replacing the PEM in order to support 3.0 batter? Another...

I planned my 3.0 battery replacement and it should be the second gen 3.0 (that Tesla claimed that it addressed the 3.0 gen 1(pre 2021), power/range dropping issue. Anyone here did the 3.0 gen 2 (post 2021) upgrade? Do you encountered any issues? What is the difference compared to gen1? Any...

Hi Rotarypower, After doing the improvements you mentioned, how does it affect the PEM temp?

Are these two pumps are Tesla specific parts that can only provided by Tesla or it is from other brand that we can buy in other places (like the Bosch pump in roadster 1.5)? if yes, what are the brand and part number for these two pumps?

Thanks !

Anyone here know whether the coolant pump for roadster 2.5 is also using the same part for roadster 1.5?

Anyone here have DIY experience for roadster coolant change? I am planning to DIY (as the waiting time at the service Center here is long and they don’t have experienced people). Appreciated if someone can share your experience here. Thanks!!!

Hi Gregd, Thanks for the reply. I did not think of the maintenance that you mentioned. Maybe adding a connector at the fan side is better. Thanks again! Nicky

Hi gregd, Thanks for the replied. Are you talking about the wiring diagram shown below? I am planning to rebuild the wire similar to what you've have done, but I am planning to do it differently. As the motor is 10 years old now, I am planning to buy a new one (image attached). I am...

Hi ML, Thanks for the reply!!! There are four pin from the PEM fan socket: Pin1. rd/bk--motor fan + Pin2. rd/yl--pem fan + Pin3. br/rd--motor fan - Pin4. br/yl--pem fan - There are only two wire (one positive and one negative) come out from the fan. Should I connect the fan positive wire...

Thanks for the reply! I am also thinking of passing the connectors between the PEM and the fan. there are four pins coming out from the PEM and two wire are connecting to the fan Any one here in the group did that and can share some experience?

Have you done the fan replacement yet? is it the right part? Any issue? I am planning to replace my fan too

Jason: I had OVMS on my first roadster (was sold) and not yet install OVMS on my second roadster, so I can not monitor the battery temp. I will do the tricks you suggested for battery cooling cycle. Thanks for the advice. You day time running light really looks gorgeous, it really stand...

Mark: Thanks a lot for the information. It really help me to understand the balancing cycle. ML: I only use the car around 2 times (usually driving short distance during weekend) and I charge it roughly every 10 days. I am also avoid having additional charging cycles, as I worry about having...
