2006 e60 525i Auxiliary Water Pump

Hi. Sorry if this has been asked before.

I have a 2006 525i with 51500 miles on the clock. The other day driving home the fan was constantly on and the amber engine over heat warning came up, and then the red warning.

Later in evening when cooked down I checked coolant level and it was at minimum so topped up, but just after starting car fan comes on again. So I take the car to be plugged in and check error codes. The auxiliary water pump comes up as having spped deviation and also switching off.

Car is now at a garage and will be seen today.

Should I ask them to just check and change the pump?

Would you suggest changing thermostat too or anything else while there (timing belt?)

I'm in Birmingham, do you suggest I source the part myself? Also where can I get it.

Thanks in advance.
Thanks for any suggestions

The first step in diagnosing a problem is to scan the engine computer (DME) and the automatic transmission computer (EGS) for codes. Thats the only way to troubleshoot a problem in a modern car. You say youre in Birmingham. Is that Alabama or England. If its Alabama go to www.bimrs.org to find a reputable indie shop that specializes in bimmers.

The car is at the garage today and will see how much this is going to cost. The part is costly so I'm sure will be about 500.

That's for pump, thermostat and replacement bolts. You can get pumps on the cheap but when it comes to the cooling system it's just not worth skimping.

I didn't get the thermostat changed when got the pump changed, and notice that after driving about 9 miles with outside temp about 9c the coolant temperature went up to 109c and no fan on. Is this normal?
Or should I go back and get a new thermostat?

Actually after driving it does go down. So is ok. Fingers crossed.

109*C is way too high, especially since the efan didnt come on. Did the efan come on before the work? What brand is the new water pump?
