...... when a Roadster's ESS fails, its not the whole pack its usually a brick or a sheet that's gone bad. I've heard of $4000 for a repair and giving a new sheet with labor, so that's not bad. When Tesla does honor a warranty, they replace the pack with a refurbished pack.
....... I too love to learn why things fail, enjoy making them better, and personally find it rewarding when everything works out and runs as good or better than new.
Like you, I like to try and learn about, and to fix my own stuff. I'd dearly love to see the workshop manual/construction details for the ESS, so that I could replace a bad brick, or ultimately replace all the cells/bricks for better ones in the future.
My worry is that recently Tesla seem to be so reluctant to either fix batteries, replace cells, OR release any technical info on how to do this [Ref Kevin Sharpe's experience in the UK . It appears that there are few/no spare ESS or sheets (or Bricks/cells) at Tesla to repair failing ESS's. Kevin has been unlucky (inspite of paying $22K for UK extended warrantee !) in that his ESS has developed a problem just when Tesla cant help... resulting in his car off the road for weeks ! and no loaner. This, IMHO, is not really in the spirit of Tesla's aim: " ...... envisioned as 'the world's best service and warranty program.' )
Whilst I can understand that keeping 'historic' roadsters on the road does not add much to the share price, and that the 400 mile pack is still vapourware - wouldn't it be good if Tesla installed even prototype 400 mile packs on any Roadsters with failing ESS's, between now and when the new 400 mile ESS's are actually available ? ..... Getting both goodwill AND real world testing in one move.
I hear such praise for Tesla and their service on this thread, especially from US owners, BUT, any one of us Roadster owners could be in the same situation next week if one of our bricks goes down, or we get an ESS related problem .. leading to our car being off the road for weeks with little hope of getting a swift repair.
