Gilly,
They did indicate to me that they did have the vehicle for a service about 14 months ago but could not tell me whether it was for an A or B service. The mileage - counter must have been there all along and they did not notice it till the check light came on and thought it was related. I am ignorant to it as I have my S430 (And older now sold S500) serviced very retentive.

Thanks again so much for the info and so quick.

Deon.
