Coolant question

[Bayerische]

I left my car into a BMW main dealer recently for a coolant change.

The previous time the coolant had been changed was at a specialist. I noted the the coolant that he put in the car was a pink colour.

When I got the car back from the BMW main dealer and looked under the bonnet, I was expecting to see the familiar blue BMW coolant, as I know BMW OEM coolant is blue in colour. I was surprised to see that the coolant in the expansion tank was still pink in colour.

I left two cars in with them that day, the other car had blue coolant in the expansion tank and when I got the car back it was blue.

Am I missing something here? Do BMW use a pink coloured coolant?, As I have a suspician that they did not change anything and charged me a fortune for doing absolutely nothing.

Yes it needed changing and I was charged for it. The car went in for a coolant change and an oil change.

I just spoke to the dealer.

BMW's use OEM blue coolant.
Mini's use OEM pink coolant.

I think when the mechanic was working on my car he saw it had pink coolant in it and decided to fill it up with the pink stuff. He should have used the blue stuff.

BMW are fairly adamant that you only use their blue coolant in their cars as it is phosphate free. I am sure the pink stuff wont hurt the car. It is more dangerous to mix different coolant types.
