Most BMW 550, 650, 750 i engines<\/strong> did or will develop a common coolant leak<\/em> which perhaps resembles a funny slightly stinky smell in the cabin, in turn could escalate to an electrical burning smell over time.<\/p>\n

The burning electrical smell could be your alternator being damaged by coolant leaking into it.<\/p>\n

Always check inspect the turbocharger cooling lines passing right above the alternator or you will be replacing the lines – hoses and plus the alternator as well, at the same time.<\/p>\n

This is not an easy job, due to the dual turbo arrangement in the middle of the engine block V configuration<\/strong>.<\/p>\n

Performing a pressure test after repairs is essential due to system complexity.\u00a0 Both after run electrical pumps should be also tested to prevent turbo charger premature early failure.<\/p>\n

There are additional lines under the alternator which should be also inspected with a fiber optic camera to ensure system reliability and performance in the long term.<\/p>\n

A picture is worth a thousand words they say, judge it by yourself.<\/p>\n
