i have recently received a "urgent safety recall-recall code JVA" for my P Ion on the basis that "water could enter the brake vacuum Pump causing it to corrode. If left there is a risk of losing the braking assistance ........" This is being replaced free of charge by the RAC at my convenience.
Yep, I got one of those letters too, despite letting Peugeot know a few months ago that I sold the car.
Too late for me - my vacuum pump already failed before the recall and had to be replaced at my own expense.
By the way, replacing the pump is not a long term fix - there was already a recall in 2015 for the same issue and they're doing a recall again 5 years later. Mine was already replaced in the 2015 recall and failed in less than 5 years!
The fundamental problem is that the vacuum pump is sitting beside the right rear wheel totally exposed to salty road spray. The only thing that would stop this happening again in the future would be an undertray and a partition between the engine bay and the rear wheels to protect the components in the engine bay like the vacuum pump to the constant road spray.
Mitsi were negligent not to fit an undertray under the rear motor compartment. The brake pipes in the engine bay area of mine were severely corroded too for the same reason.
