    W737 Recall

    Has anyone gotten this notice?

    Got a notice late last week (Thursday, June 26) about a recall called "W737." As I was having some cooling system problems (loss of some fluid), I took it in. According to my service receipt, the W737 campaign was to "deactivate speed setting 1 of the Engine Compartment Blower. The design of the speed control mechanism of the engine compartment blower can cause a thermal overload of the supply line if the engine-compartment blower is sluggish or blocked in speed setting 1. What the service folks did was to reprogram the DME control unit by reading out and erasing the fault in the memory.

    If you're losing coolant it's most likely your lousy cap.

    Re: W737 Recall

    The dealer checked the cap and said it was okay, but I have a spare just in case. The W737 recall was for some coding that turned the fan on and off at certain points, and it needed to be reset. I thought that might have been the reason for the loss of coolant. I had also noticed that while the water temperature was okay (at 175 degrees Fahrenheit or about 79.5 degrees Celsius) the oil temperature was pushing up towards 225 degrees F, and the highest it gets with most of my driving is around 210-215.

    I wonder if there is a problem with the thermostat, but I guess they would have checked that when they checked the cooling system.

    I had mine done in May. It was an issue with the blower fan I was told.....Anyway I got another new "fan"
