Chrisblob 3 Report post Posted August 20, 2018 Hi all, my E60 540i is losing about 200-250mL of coolant a week - no obvious blue coloured puddles on the ground, and I haven't seen any build up of leaked coolant anywhere under the hood although its hard to see if anything is on the drip tray or in some crevices. Am waiting to hear if the mechanical warranty will cover diagnosis and repair. Can anyone recommend a coolant specialist in Christchurch that doesn't mind working on BMW's? Regards, Chris W, Christchurch. Quote Share this post Link to post Share on other sites

Regards, Chris W, Christchurch. You want a BMW specialist, someone intimately acquainted with the N62. It's a complex motor, and needs all the right gear for re-timing valvetronic if the heads need to come off. Hopefully it's not your coolant transfer tube (becoming a recognised issue with the N62). MBI should cover. Here's a hint. http://www.bimmerzone.com/product/PRT-AGA-PIPE-N62.html Best of luck. Let us know how you get on. Quote Share this post Link to post Share on other sites
