I havnt received my letter yet, and I think I know why. Just booked in for my first service due on 6 October.
First available date to have the recall done at the same time was well into November
The dealer said
its 'because it takes all day' .
But booking just a service without the recall was no problem with a choice of dates and times in early October.
I have decided to delay the recall for a while and just gone for the service as I dont want my travel plans for November disrupted.
The dealer said "No problem, its not a safety recall". Not sure I totally agree , but I have not noticed any problem and I have never relied on it completely. And as some have pointed out I have managed many years without it, including 1 year when I assumed I had it when sometimes I might not have. So a few weeks delay is no great biggie.
