E-Box replacement on 2020 Taycan

[FrancoMarquis]

Hi all,
My first post here, however I have been lurking around quite a bit and I wish to thank all the contributors to this site.

Here is my story: I am in Canada and I am a happy camper with my 2020 Taycan 4S. My goal was to keep it for a long time, given the miserable depreciation of the car. I really like the car. I keep charging it home to 80%, etc basically good habits helping to maintain a healthy battery, etc.

A happy camper, until... I had a red screen of death event. I could not resuscitate it using the lock/walk away trick. So to the dealer it went, on a flatbed.

They had a vey difficult time to diagnose the thing because many computers were also downed. So the fix Porsche Canada determined was to replace the E-Box. They did, and I recuperated my car 3 weeks later. All is good except...

When I questioned my dealer about the WNQ8 recall campaign, they told me that: "it is not applicable because my VIN is not specified in that campaign". Yeah sure, the eBox was replaced yesterday... how can it be ?

This is a circular argument I think, because the bulletin says: 1- car applicability is Y1A/Y1B, 2- They admit to a workshop manual error, 3- they specifically target vehicles that had only the e-box replaced, and, 4- the result of this action can be consequential damage to the HVB over its service life (Porsche had publicized it to be at least 15 years and 300,000 km).

The recommended action specified in the bulletin is to replace the whole battery, which Porsche Canada failed to comply with.

Now, given the dealer's response and Porsche Canada decision, I am at odds as to where to escalate this issue.

Can someone who relate to this can shed some light to this issue ? I would greatly appreciate.

You can have a lawyer contacxt them and have them confirm why the repair was not performed as per porsche's own service bulleting WNQ8.

At that point you have it in writing, and if anything does happent o the battery, you can tell them that they did not follow the procedure.

What's an E-Box?

 

[Tooney]

The TSB for WNQ8 specifically states that it applies only to the affected vehicles, listed in the service campaign. An internet posting from PCNA to dealers stated that WNQ8 only applied to 9 US vehicles.

The TSB also states

The E-box is part of the high-voltage battery scope. The E-box and high-voltage battery must only be replaced together.​

The question is whether the statement about e-box and HV battery must be only replaced together applied only to the 9 US vehicles in the WNQ8 campaign (which could have had the work done for specific problems unrelated to your car's situation) or it applies to more than those vehicles.

I know that since WNQ8 was issued, other forum members have reported that their cars have had the e-box replaced.

I'd send the TSB and the service paperwork to Porche Canada and ask them for definitive clarification for your car.

Good luck.

Thanks, good point. I would also add that the admission of the error in the workshop manual further muddies the scope. It certainly opens the way to a wider target audience.
