Hi - I have a 2007 1.6L Petrol 1 series and it has wire connectors in the boot near the battery but I don't know what they are meant to connect to. Are they just spare or is there a part missing?

The car currently not starting but we think it is a BCM fault but just wanted to know what the cables in the boot are meant for.

Any help would be greatly appreciated be gratefully appreciated as we can't read the fault codes as we think the BCM is faulty and the car won't idle properly but there might be some other issue.

 

Regards Andrew

Morning Andrew

Welcome to the Forum

looks like your missing a module rear camera or PDC could be a Towing Module

Not sure about BCM (I assume this is Body Control Module?) BMW 1.4.0 or ISTA/INPA should/normally show Greyed out Modules as not communicating allowing indentification of Failed units

The Footwell Control Module was a common issue on several models and a simple change whether you go new or recycled it will cause a Tamper Dot by the mileage, so your new unit will need to be registered to your chassis and the mileage matched to your car. Junction Box Electroncs is the next biggy mainly due to where it is situated. 

Dont forget check or better still change the Fuel Pump Relay one of the common faults

Also disconnect the modules check the connectors for signs of corrosion on pins give every thing a clean and spray of electrical contact cleaner and put it back. I have fixed several this way.

Good Luck

Hi Dave - Thank you got the excellent advice and information. Could you tell me where the main fuse box is (never had a BMW before)?

We have a friend coming over to scan the car on Thursday so hopefully sort out the issues or at least know what to fix first.

Thanks once again - Kind regards Andrew

From Memory you have a Fuse box under the Bonnet, the main one behind the Glove box and one in the boot

You should find a fuse layout folded in one of the boxes 

Fingers crossed it's a simple fix (Fuel Pump Relay) 

Good Hunting

Dave

Thank you. Do you know if there is a red cable missing as I have seen it on other 1 series?

Morning Andrew

The attached drawing is from www.realoem.com it seems to show you are infact missing a connection (item 6)

Dave

Looking at the drawing it connects between the power lead right connection in your Photo and the main power distribution on top of the battery arrowed in your photo
