Do not care about an older BMW

<p>I took my BMW 2.8 e36 to be serviced by Fors****s - on the invoice they charged me for 2 x 1L BMW coolant after asking for the cooling system to be flushed per the service light inspection. The back of the empty BMW coolant bottles state to mix equal parts of the coolant and water. I looked at my car’s manual after getting the car back and the engine coolant capacity is stated as 10.5 litters ? Fors****s Tygervalley - BMW Dealership then only replaced 4 x litters of mixed coolant and water if you look at their invoice OR they only put 2 x litres of coolant in the engine with 8.5 of water. Why will Fors****s only flush the cooling system and replace 2 x coolant units and not 5.25 L as per the manufacturer specification ? I have all the invoices to prove the charges where they also state a engine coolant flush was done. This dealership is either cutting corners by mixing less coolant with more water that will result in damage and colrosion to my car's cooling system in the long run or they only replaced the coolant in the radiator and not the engine block as well – either way not the level of s**** you expect from a BMW ‎approved dealership and does not leave a longstanding BMW customer who is trying to look after his older BMW with "Sheer Driving Pleasure" </p>
