E89 Roof problems - code A69D - CTM - where to start?

[BigCL]

Hi guys - my broken orange three wheeler is fighting me all the way. Roof still not fully closed and windows are down. Red roof light flashing away. After spending £££ on a Carly adapter and their full licence I have finally uncovered the code A69D which some websites say means "CTM: Valve 1 for rear-end module". Carly also mentioned Valve V3 and V4.... Any thoughts on how to start diagnosing this please guys?

Carly is pitiful at actually explaining what the codes mean, so my advice may well be not to waste your money.

 

[BigCL]

Guys... can no one help me with my A69D code please? Helllllpppp

Yes, I can. - you as well.

Where are you from? It's neither to find in your profile nor (AFAIK) in any of your messages.

Important for every Z4 owner:
Red roof light flashing is NOT a fault indicator!!!!
It's only an indicater, that the roof is neither open nor closed. That's it, nothing more. Just anywhere in the middle between open and close, but never ever a fault indicator.


Your fault code states the following:

The fourth solenoid of the hydraulic pump is
- missing (as there is an elder pump mounted from before March 2012)
- is not connected
- the complete car is from before April 2012, but a newer CTM got mounted

There are some incompatibilities possible, which can be solved.

Unfortunately Carly is the most worse tool regarding roof isssues. It can't help. I've discussed this already last year directly in their office in Munich. But nothing has changed since. More and more gimmicks, but less substantially improvements in the last year.

Maybe the foxwell scanner NT530 might be a better option for semi-professionals.

hi - I’m in Coventry UK. Car is 2014 and has the 4 valve pump. The car has not been modified. Where did you find that code explanation?
Thanks for your reply.

Car is E89

Hi Chris,
ok, wasn't clear for me if you are from UK or from the states.

Where did you find that code explanation?

You will find explanations for error codes on this website:

BMW Fault Code Lookup - BMWFaultCodes

As multiple results may apear, have a look at the ctm_89 code in the ECU column. Or sth. "E89" similiar, if it's not for the CTM.

Well, check the label on the hydro block of the hydrolic pump. It containts the production date on it:
"BW0A10090261" states year 10, week 09, pump number 0261 in this week

Have a similiar look at the CTM:

Produced in week 21 of 2009

If both components have a similiar age, that should be fine and there might be a problem either with the wiring between the CTM and the 4th solenoid, or the 4th solenoid got damaged in any way.

Solenoid can be tested by just putting +12V on it. No risk.

It would be ok to "power up" by using a "Snap-On" power Probe (or similar) as they have circuit protection Robbi?

[BigCL]

I'll check these things tomorrow - many thanks for your replies.

The problem is, that these solenoids may hung after some months/years without any usage. Putting them on 12V let's say 10 to 20 times these solenoids will "wake up".

So I am assuming the 4th solenoid is the one sitting on its own (on the opposite side to the three) and it has a "metal" cover? When I take a closer look at it, is it clear where I should be putting the +12v? It was pouring with rain today so I was lazy and didn't check it. I will tomorrow !

Thank you again!

Correct. As these solenoids work like a simple relay, it doesn't matter which pin you put on 12V. Keep care on avoiding a short between +12V and ground in this area!

That is why it would be good to use a Power Probe, if you apply power to the wrong place it "trips" and you have to reset it.

Done this many times, mainly to ”wake up” lazy AC compressors when they get stuck.
if the car has been sat a while this is probably what the solenoid needs,if you can run The engine though and give it a 14v kick up it’s arse, you may have better luck with it.

 

[BigCL]

Does anyone have the part number for the 4th solenoid please?

 

[RobbiZ4]

Sure that it doesn't work anymore?

All 4 are of the same type. When I replace any, I also replace all 3 different (!) o-rings to avoid any leakage by in most cases 10 year old o-rings.

But at first, I would swap it with one of the other 3 solenoids. Same as with spark plugs.
If the fault code changes to another number, replace this 4th solenoid. If it stays on position 4, it's the loom between pump and the CTM or at least any of the 2 plugs on both sides of the loom.

 

[RobbiZ4]

Does anyone have the part number for the 4th solenoid please?

Not available from BMW in the E89 parts catalogue. But...

 

[BigCL]

but...? Also, do you have apart number for the O rings - that is a good idea to change them if I'm moving them around.

Thanks Robbi

Hey Mr. @BigCL, any update?
