Annual Inspection Checklist:
1. Inspect operation of all parts of the car electrically including lights
2. Evacuate and recharge the A/C refrigerant
3. Check chassis/tires/brakes
4. Remove PEM and clean air cooled heat sinks
5. Test motor and cable integrity
6. Update firmware level
7. Reset service indicator
8. Apply all outstanding bulletin/campaigns
9. Charge Battery
10. Clean car
Some Service FAQs:
Q: Why do you check the HVAC charge? No other OEM’s recommend regular A/C service?
A: True, other OEMs recommend HVAC service as needed, but not as part of regular scheduled service. On Tesla Roadsters, we rely on HVAC to cool the battery during charge. If the HVAC is undercharged or not functioning properly, it may cause charging issues. It is important to know the system is properly functioning properly so charging is not affected.
Q: Why do we remove the PEM during service?
A: The PEM is air cooled and the heat sinks used for cooling are on the underside. To access these, we must remove the PEM and turn it upside down. At this point we check the motor and cable too. A high level of current is passed through the motor cable. If any degradation exists, the cable may breakdown over time and cause the car to not drive. It is possible through testing to mitigate this .
Q: Why does the brake fluid need changing every two years regardless of mileage?
A: Brake fluid is hydroscopic, which means it absorbs water. Over time the brake fluid will accumulate moisture. When the brakes are operated they generate high temps in the brake fluid. If moisture exists, it may cause the water to boil and steam and cause an air pocket in the fluid line. The result may be a spongy pedal or brake problem.
In a nut shell, you can drive this vehicle 15,000 + miles a year for less than $1,200 ($0.03 mile x 15,000 = $450 + $599 annual service)... less than what it costs to fuel most sports cars on a yearly basis!
Hope this helps...
