CC-ID 271 convertible top vehicle speed
- Thread starter Amg01
- Start date
I've had it but didn't know anything about it until after it had been cleared by the dealer.
Its a 2009 35i dealer had the car to repaint both roof panels (small areas of paint bubbles on corners done under 12 year corrosion warranty) and some waranty work) Car was with dealers for about 2 weeks whilst waiting for a new fuel pump. On return roof didn't work properly, no problems before it went in. Dealer technician came to my house and manageed to get the roof to close properly and took it into dealers. He returned car next day saying the fault was due to the car being driven at overspeed. He had info on this on his phone with date and time - which was during the period that dealer had the car. I didn;t ask him what had been done to clear the fault and I was not charged anything Could have been that the code was just cleared but may have involved some sort of reset process. The roof failed in 2 different ways- once with the boot lid in a nearly vertical position and secondly with boot lid hinge about 1" above the plastic panel to the rear of the seats.
Before taking the car away he did operate the roof on opening it with the boot lid nearly vertical he pushed it tio ensure it had made the maximum travel. From memory it than seemed to lock down properly -cant remember him doing any thing else.
I did have further problems again shortly afterward s- roof was up so I took it into dealers again they replaced both the salmon relays- old ones were originals dated 2009( . No problems since so maybe best action would be to check and see how old yours are and replace then with genuine BMW ones and see if it helps. Only about £30 for pair and an easy diy job

I had this a few years ago when I also had roof not latched warning come up on the iDrive screen, constant bongs for miles 
I thought it was related to the switch mounted in the rubber above the windscreen on the right hand side. BMW Part 54377192950 - Convertible Top Latch Base Sensor.
I could hear the motor latching and unlatching, plus no amount of pushing on the roof would budge the roof panel, confirming in my mind that the panel was latched fine.
I probably did the wrong thing and committed a cardinal sin, but I sprayed a small amount of WD40 on the sensor switch and exercised it manually. Not had it happen again since that :driving:
Cheers!

IT IS "driven too fast while not latched", nothing else. Might have happened ages ago and doesn't matter at all. Only base for new rumours.flybobbie said:
And please, once again, no WD40 anywhere in the roof's construction!

That autobulbs URL is a great resouce

Duly noted Robbie, I was young(er) and naive when it happened :-|
My only excuse is that this happened early in my Z4 ownership and I hadn't picked up the wealth of knowledge shared by you on the topic. I have since noted and apply all of the top guidance given for Z4 roof maintenance. That was my one and only transgression... honest! :lol:
Cheers!

If you have a garage I would open the roof and lubricate the latches on the leading edge above the windscreen. You might well find that simply opening it and closing it will reset everything. No reason it should go defective if its not been used, maybe a hard bump has knocked a latch back a few mm..
Use white lithium grease in a spray, shake well

The question was regarding the following fault code:
CC-ID 271 Convertible Top, Vehicle Speed
It means, that the speed of the car was higher as the speed limit configured in the CTM, the roof control unit.
This limit is depending of the age of a Z4 E89 as well as of the inidividual coding status. Standard limit in the first years was 6 km/h, not more. Later models got higher limits up to 30 km/h as well as 50Km/h as of about 2012.
ID 271 does not indicate more than the simple fact, that the driven speed was higher than the configured CTM limit while the roof was not completely latched. That is not an issue, nothing is broken or needs any grease.
There is nothing to reset, there can't be anything resetted at all. It is only the documentation in the list of fault codes, that this limit has been exceeded.

The limit can easily be increased, e.g. with Carly. But...B21 said:
There is a special situation in which problems with the roof shells can arise when opening while driving. That was the reason why the hydraulic pump got an additional solenoid in 2012 (the 4th one), an extended hydraulic harness as well as an improved CTM, that is not compatible with the elder Z4. With these improvements, the speed limit was raised up to 50 km/h.
Without these improvements a low risk remains. I would not recommend to change this limit on a higher value than 30 Km/h.
Yes, indeed, that is correct. But this limit initially was set to 6 km/h, which never ever could damage anything.flybobbie said:
This limit can already be exceeded if you release the brake at a traffic light when opening / closing the roof on a Z4 with automatic transmission and start rolling.
RobbiZ4 said:Yes, of course.B21 said:30 kph works for me thnx better than 5-6 kph :driving:
But don't expect mph! I'm only aware of 6, 30 and 50 Km/h. Don't know, if there are translated units available in the UK versions of the CTM.
Yes it’s kmph…or the hex code in the CTM is 1E
