Hi everyone,

Just after some advice really. I've been told that I need a new CCU for my 2007 Freelander as it has a really odd electrical fault. The indicators and wipers turn themselves on (making it VERY difficult and dangerous to drive). The garage have told me that the problem lies with the CCU (or is it BCU?). Anyway, they've said it needs replacing and apparently they're £800 + fitting.

Does that cost sound about right? Are they ripping me off? If they are, what should I do?

Any help is much appreciated!
 
can you not get a universal one that programes itself, my lads car needed one about 300 pounds but fitted a universal one about 70 pounds on his, i think they are on ebay.

Aren't the CCU's coded to the engine's ECU? At least on F1. So the engine is imobilised if the CCU hasn't got the matching code.

Yes, I've heard that but I know that you can have them reprogrammed and that would be cheap considering the alternative of buying a new one...

It's a freelander two I think...

Oh dear!

Does it have a badge on the back something like this....

A 2007 should be a FL2. It will have a BCM. These don't go wrong very often. But I believe they can get wet from leaks in the body somewhere. If it's got corrosion, then a replacement is the best action to take. A BCM for any car won't be cheap, especially something complex like a FL2. From memory some suffer bad connections at the multi-plugs too.
I would try to see if it's just in need of a plug re-seat or a software re-flash before it needs replacing. The wiper problem rings a bell, but can't think why at the moment.

There are freelander BCM's on eBay for relatively cheap. How do you work out if they're compatible?

I think you'll find that's for an F1 - at least googling the part number shows it to be for an F1. Heaps of F1s in breakers and parts are cheap. Not so many F2s.

FYI as you said above, be careful about swapping out individual computers as they may be coded to others on the car and replacements won't work. See post #9 on this thread...

This has intrigued me and I've done a bit of digging.

The only conclusive thing I can find is that I hope my old F1 will last till I die - cos I don't want a car controlled with dozens of ropey computers like an F2 or probably anything released in the 2000's!

Reports of F2s doing random s**t appear to be quite common. A high proportion of them initially blame the very expensive BCM or CJB but usually it is something else and completely unrelated to the faults being experienced. So if it was me, I would not spend £800 for the part even if it was a guy in a LR dealership in his LR overalls talking like he really understands the problem. I don't know what I'd do - because as you say, you can't have the indicators coming on when you don't want them to! Its a difficult situation.

Have a read through this thread, the problems, the garages suggestions and the actual solution in the last post (together with the other experiences in the thread)...

Pretty difficult to avoid ECUs now GG. My D3 had 11 of them. All linked by the CAN bus. With this many ECUs in one vehicle, the ability of the diagnostic device used needs to be extensive.

The OP needs to get any software updates done in all modules, before replacing anything.

I agree Nodge.

I was a bit wrong in my description, because it sounds like the actual main computers are quite reliable - but its all the bits that they monitor can throw one or more of the networks out - I think the CJB on F2 has 3 different networks going to it. Once the networks start getting unreliable then strange stuff happens and the diagnostics can not work out what is causing the errors on the networks.

There was a post on that Freel2 thread that amazed me...

There is a main connection for both CAN buses on the base of the right A pillar. If you remove the carpet on the base of the right A pillar you will see the three connectors there. Check them.

So the network connections in the footwell are "protected" by carpet!

The old carpet protection system is used. I've heard about that:p.
At least in the D3, the CJB is behind the glove box, well above the foot well. The D3 can also suffer water ingress to the CJB contacts, which is annoying.

I would get fault codes read from the BCM as a first port of call

The wiper and indicator switch is on a LIN bus to the CJB and can be checked best with an oscilloscope but a multimeter can give a rough idea if it’s working

Does cruise control work and all switches on light switch?

The BCM contains the key data and config file so can’t be swapped from car to car - new is the only option

Haven't tried cruise control yet but I'll check this afternoon! A friend of mine that works at JLR reckons BCM's can be reprogrammed....
 
Found this video on YouTube earlier which appears to show the same problem. Perhaps the garage are trying to cash in by having me buy a new CCU / BCM when it could just be the wiper stalk!



Thoughts?

The BCM and other modules need to be flashed to the latest software version as I suggested in post 9 and 14. ;)
