Hi all , just joined need some help with my 09 C220 , been losing coolant for a couple of months but as I thought it would get worse , took it to my indie he says he thinks it’s the oil cooler , but has no interest in doing it as he’s moving abroad and said it’s a bad job labour intensive , wondering if anyone has had this fault and if it’s possible to diy any thoughts or direction to any videos would be great
Cheers David
