We replace the internal fan when we refurbish PEMs; the part number is 3108NL-04W-B30-P00.Oh by the way I forgot to ask... Does anybody know the references of the PEM internal fan? Is it worth replacing it with a new one as we're at it? After year of spinning it must be tired no ?

Unless they experience atomized aluminum or develop a precession from a bad bearing, then they are likely fine. It is a mechanical part that can wear over time, but a year is playing it too safe.
The one I got was: CT-R708S
They cut the strips for me: 167x32x1mm
Price Including shipping was 187Euro
Now its time for my upgrade of the PEM. Got 909 DCM HW: PhaseB Low Side Desat Fault. What I can understand from this thread is that I need new isolation in the PEM.
@hallvardr: where did you buy the stripes you used? Still working good?
Why not make the stripes larger? From images of DanielFriederich post #314 it looks like the problem was close to the edge of the stripe. It also looks that they could be a few mm larger without touching the screws or the tempsensor.
I am currently upgrading my 2010 roadster to the new battery and was told I need a $7900 PEM replacement due to heat problems over the years as described above. I had intermittent problems which I can document with emails and service checks while the car was still under warranty, having gotten an extended warranty (3 or 5 years, can't recall) negotiated in when I originally purchased the car. Has anyone had any success in getting Tesla to own up to their design flaw and replace these under warranty?
Who is taking care of the battery while it waits? Charging and driving it regularly?a Signature series one #57 that I can't import until 2024 (due to Tesla not making the couple parts for Canada compliance). So that one is stored in US.
That would be asking too much of the service center technicians who don't have the right equipment, parts, or training. That would be the job of remanufacturing, yet even they don't do that as far as I'm aware.I know the PEMs are all coming to the end of their life span but the Tesla service centres can clean them but they can't do the logical thing that would involve servicing them properly and replacing the wearing transitors, insulation, etc.
Get log files along the way too.I think I will be starting to collect data on this - collect the numbers of failures with time frames after service.
As I'm now reading, maybe a PEM Tesla cleaning might be the worst thing you can do. Based on both PEMs failing within a month or two of said service. .
Tesla did create a snow dam that goes around the cooling fans. It's simply three walls that surround the fans and provide protection from snow. It could be easier to get one of those and add filters to it. In fact, we have a machine shop that could recreate them too, and add slots, holes, and pem nuts for the filters.There are several solutions. I'll plug mine ... as it uses large area filter, to avoid limiting air flow
It can be done, and it makes servicing the PEM much easier. The only drawback would be getting access to the cooling duct for the PEM. You need to remove it from the underside of the PEM to blow it out from the inside, and in some case wipe down in the inside lining with a wet rag to pick up the dust/debris.is it possible to remove the rear luggage liner, lower under floor shield, and maybe (if necessary) the rear bumper (sorry fender) to access the PEM
How about the motor? Seems the SC reports needing to remove a bunch of leaves and such from both the PEM and motor at every yearly service.You can clean the PEM without disconnecting anything. With the car up in the air, you can remove the cooling hose and access both the inlet and outlet ports on the PEM. The cooling air just blows across the heat sinks on the bottom of the PEM, not the internal electronics, so you can get in there with a blow gun and not worry about damaging anything.
Yes, that's the same stuff we've been using for years.I presume the right version to use is "D5", correct?
