Hello guys,

I just brought my 04 x5 4.4 with 33,000km for oil change. The dealer calls me back that they suggest my car needs to have a coolant flush, and a fuel injector flush. are these neccessary? is coolant flush for every 4 years? How about fuel injector flush? what does that do? how often?

The above 2 jobs cost around $350.

Please help..

Thanks
