Fan / water sensor

[Dave 2 dogs]

Hi all , been a while .
Just not been as enthusiastic with the car this year for personal reasons.
I’m after some help please…
The water fan is coming on , and going off, intermittent ,
Even from cold start , which kind of points towards the coolant sensor, I know there are 2 …. One at the top which is the temperature sensor, and then the fan sensor. It’s this I’m struggling with, looked at a couple of videos, and it shows it on the bottom radiator hose in the video. But it’s not there on mine. Anyone know where else this might be please?
It’s a 35.i 2013 e89
Thanks in advance

Have you read the error codes…this behaviour is sometimes associated with failing water pump..

[Dave 2 dogs]

Hi B21
Just borrowed a code reader , I’ll be using it this afternoon, I’ll let you know how it pans out
Thanks for the info and the water pump
Hope it’s all good your end

Put the code reader on the car and it came up with these

Pump is around £320 from Indy sources…need to do thermostat at the same time around £80…probably 4-5 hours labour..

I’d imagine at BMW it’s over a grand..probably closer to £1,500…

Replaced both pump and thermostat as stated .
Got out for 2 quid short of £1k
Thought I’d let you know .

Jeez! How much of that is labour?

[matsmith749]

It's a big job - book says 6 hours for water pump on it's own.

I'm assuming this was an indy, so likely £500 - £600 of that bill was labour.

Always feels like a spanking, but I guess they gotta eat & premises / tools / ramps don't pay for themselves.

Mine went at 55k

Mate and I did the job

It’s not easy

We took a weekend working slowly at it

Wish I’d taken it to my Indy

My guy did it in 3 hours. The pump was indeed over £500 though

I’m happy with the price , you mentioned the cost of the pump , plus the thermostat, and plus vat . I think it was reasonable to be fair. Like you said. They gotta eat
If I’d booked it with BMW they would have probably said a month or something wait time. Plus much more money. It’s another tick box for things that go wrong on these. Along with the roof fail which I did last year. So less to worry about, and more to enjoy, plus a bit of incentive for the potential buyer when/if I sell
