So to me it would have made more sense to hold the cars back until some of them have had this fitted to see if it does cure the problem or not
Hi Les - Although both you and me would think this be the sensible thing to do, purely on the face of it.
I am afraid the cash flow of the dealers, would dictate a different approach.
A lot of dealers where expecting a big uplift on their through put of actual sales at the back end of 2021 and again at the start of 2022 ( Given the volume of orders they had already received ).
However, due to the unpredicted huge lack of availability of actual cars, their predicted income for this periods, has under achieved massively to target sales.
They did receive a life line when MG released the MG4 only a few months ago and promised delivery of around 2,000 cars before the end of 2021.
Reviews of the car have been very positive and this has also increased the demand for the car.
Some LONG suffering customers of the ZS EV ( Gen 2 ) have given up and either ditched their orders completely, or switched across to the MG4 as well.
Therefore, as soon as ANY new car ( sometimes unexpectedly ) arrives at the dealership, they want it into the workshop and out of the door ASAP - so they can receive some type of revenue.
They are VERY unlikely to have enough storage space, to accommodate storing all of the MG4's awaiting the modified breathers to be honest.
Stored cars don't pay the bills unfortunately.
It's really not in their interest to find problems on the PDI checks. if you get my meaning.
Get them delivered and THEN deal with each complaint, completely on a "one by one" basis.
Installing of the modified breathers will be dealt with on a similar premise I guess.
Adopting a similar mind set, that surrounded the ZS EV ( Gen 1 ).
Cars with know "buggy" software applied, that was causing huge range and power issues.
They dealt with this problem in the same way, purely on "one by one" scenario.
Customers who presented with the issues, had their cars updated, those who did not report any problems, never received the update or got contacted personally.
Hopefully getting picked up at the time of service - maybe ?.
I bit of a "Don't ask, Don't get" type of situation ?

I was actually told this fact by my local dealer.
