What does the recall concern, or what is its designation?
If the recall involves replacing the traction battery, you shouldn’t have it done, because they update the TBMU software first, and that’s when the trouble starts. This applies to both the old battery and the new replacement. Ultimately, it just results in you spending a huge amount of money.
Firstly, this primarily affects the DS7, C5 Aircross, and second-generation 5008. Secondly, it involves changes to the TBMU software that reduce the tolerance for voltage differences between traction battery cells; consequently, an old battery triggers an error quickly, while a new one does so somewhat later. See: costs, costs, costs.
Not at a DS Store, but rather at an independent workshop that is well-versed in this issue.
As the recalls are initiated by the manufacturer ( in your case DS) who then get DVLA to send out the notices, I’d trust the DS recall web site to be more accurate than DVLA.
If you have put your vin into the DS recall checker, and there is no recall showing, then personally I’d be happy with that.
