Yes it can.

The E60s power system is designed to use large amounts of current and is fairly particular about the system voltage. If everything is working properly, normal system voltages can...

I'm pretty sure the 30g-f relay was introduced with the junction box in models beginning in 2006 (unfortunately after the 545i). Given that the E60 was introduced in Europe in 2003 they probably...

Hey HF,

Your voltage regulator is going bad. When mine failed my voltage would go as high as 17V on start up and sag as log as 11V after warm up but was random.

Don't forget to stir the gears first before pulling the plug. I forgot during my last drain and fill and was scratching my head as to why more fluid came out than went back in, and then remembered.

I wouldn't worry about that. Tell the dealer you have free towing (they won't know whether you do or not).

I would also strongly suggest you change the trans fluid...

I think it was 5/16" copper tube. But take one of the flexible rubber ends with you to the hardware store and test the fit.

If it is only a long crank on a cold engine start you could tell them to try reprogramming the car, but my guess is that they will be putting in another HPFP. Tell them to check the tank pump too.
