@ajp558 - who took his lamps out and sealed them himself when he had the same problem - sent me this video, which although it talks about modding the lights actually goes through the process for removing them:Any idea how easy it is to remove the unit and check for water ingress - ie invert it to see if water flows inside?
Tesla dismiss the fault with nothing other than looking at a photo which, imho, based upon the above is invalid. We had a couple of recent service visits of which condensation was on the list. Even though it had been previously agreed by a visual inspection at a previous SC visit, it was dismissed this time because they wanted more fresh photos. If it was a 10 minute job to remove and inspect the unit, I would have thought that this was better for Tesla to do instead of merely dismissing out of hand.
The following video shows how to get access - dead simple, but not how to remove. nb, the fault being fixed was down to a third party Tesla contracted bodyshop, not Tesla themselves.
Jump to 2:30 in the video to begin with.
It doesn't look particularly difficult, looks to be a couple of nuts at the back and a large black nut on top that the boot rests on. Jump to 6:21 in the video to see where he actually removes it. From the looks of it you pull it away from the rear of the car.
I've had a followup text from Tesla asking me to confirm my address, phone number and whether there is access to the drive. I suspect this is probably automated and at some time between now and 08/05 I'll get an actual person who will tell me that it's "within spec" and to go away. If that happens, I'm definitely going to pull them out and try sealing them myself. I do not believe that the "natural venting" excuse is valid, since everyone seems to experience this phenomenon differently, and not at all in some cases.
