Hi, As mentioned I will now asked the other part that was added to my 89 740GL. This is a little black gadget that was installed closed to the tank where you fill up the antifreeze.
I didn't ask him waht it was until I looked on the invoice and it kinda looks like he wrote down "Radio Resistor"..
My mechanic told me to test it out after I told him my car stalled on the highway... He installed this thing before replacing my Fuel Pump Relay just a few days ago since my car stalled again (about 3 months after this radio resistor was installed).
Anyone heard of this device/part before?
Thanks!
