coolant flush.
 

My local Dealership sent me a message " scheduled maintenance required "
that pertains to the coolant system being flushed.
They recommend this service at 90,000 km. ( or four years ) so my four years is now up but I only have 43,000 km. on my 8.
Has any other owners had their 8 in for this service ? and do you think that it is really neccesary with only 43k. on my car.

Thanks,
Buteman.

Should be done every other year in my opinion. Easy to do yourself, even I managed it :)

I flush my cooling system twice every year but that's overkill :)
After 4 years i would do that regardless of the mileage though.
