R56 base model (MY 2009) 50,000 miles.

No matter how hard i pushed the gas pedal, it has NO throttle response at all when I start my car in the morning. it is just idle normal. I need to restart the engine and it will behave normal again. It happened to me quite a lot of times at traffic light as well :(

Any solution for me to try to fix?

Thank you.

There are two potentiometers in the throttle pedal that provide 0 to 5 bolts signals to the ECU. On power up the ECU looks at the voltage of both. If one or the other falls outside the expected range or the difference between the two is too great it can trigger a plausibility error. Since the ECU feels it can't trust the input from the throttle pedal it ignores it for your safety. I'd say it's time for a shop visit and probably a new pedal.

 

Can you check the error codes stored in the engine? It would be useful to help troubleshoot...

 

Looking at 0:32 shows two seaters...is your car a convertible? if not, then the speedometer isnt programmed right. as alexs3d2 said, get the codes out for us. how did all this happen?

 

update...

Last week I swapped a good throttle pedal from my friend's r56 (same model), however the problem still persist.

After the swap test, I installed back the good throttle pedal to my friend car... my friend's car had same symptom of "no response to gas pedal" ONE time only. After that, everything is good.

Visited workshop today and after scan... pop up fault code 2BE4 DME internal fault... the workshop ask me to replace ECU???

Please help.

 

Can you also swap his throttle body or buy one to test?

If your mechanic has a regar scanner, it may shown wrong codes. My scanner did the same with my countryman. I used .another scanner and even live data to pin point the issue.

How did you do the paddle swap?

Where are you located?

 

Paddle sensor swap is easy job.

That mechanic used genuine BMW scanner and get the code "2BE4 - DME internal fault". I scanned with my Launch easy-diag 2.0 (BMW software loaded), it shown the same code.

I cannot find any info about 2BE4 in google.

 

Searching 2BE4 in ISTA returns three hits.
DME Internal fault.
Pressure sensor before throttle valve.
Low fuel pressure, operating range: Pressure too high.

If your friends R56 has the same part number MAP sensor on the charge pipe on the passengers side I'd try swapping them, clearing the code and see what happens. If no change I'd try replacing the fuel pressure sensor on the fuel rail. Those sensors are cheap compared to a DME.

 

Before you change any parts and spend a crap load of money in the shop have the ecu reprogrammed and updated. If you have a good relationship with a mini dealer they will probably do it for free. Otherwise I think it’s about $200 to have it done.

 

Any resolution to this? I have the same exact problem. It idles around 1k and the accelerator pedal does not work. I also get the DME internal fault. It's intermittent, it happens occasionally.

I did take it to the dealers and recommended reprogramming the DME to try that. We did it and had no issues for about 3 months, but now it's happening again.

Any insights?

 

accelerator pedal sensor?

 

i hooked in a Fox well scanner and looking at the live position sensors for the pedal, both of them are reading. But the acceleration pedal % was 0. It didn’t change. When i don’t have the problem, I am able to see the acceleration pedal.

from everything that I have read, I am assuming that it must be some kind of electrical harness issue, since it’s intermittent. I would think if it’s truest a DME hardware fault it would happen all the time.

i think I am planning on sending the DME to ECU PRO to have it tested to see if there are faults so not. This will help me isolated whether or not it’s truest the DME.

 

Any update on your issue?
I have the exact same problem on my 2007 Mini Cooper R56
DME Internal Fault 2BE4
No throttle pedal response with half engine logo on the dash, turn the ignition off and on, pedal starts to work with still logo on.
I checked/swapped the relays in the fuse box, nothing.

 

I'm not sure if this is relevant, but try re-setting the throttle synchronization.
Gas pedal to the floor & hold it there
Key in, ignition on (engine not running) for a good 30 seconds
Ignition off & key out
Foot off gas pedal

 

I ended getting a refurbished DME. No issues with the DME fault or throttle response anymore.

the shop where I bought the DME looked into mine and diagnosed the problem with being the power supplies which they claimed could not be repaired due to the complexity/risk.

 

Do you need to do any learning or adaptation procedure when you install another DME?
Because I know Mini and BMW is so sensitive about replacing DME, ECU or KEYS you need to program them.
Or the company just cloned your DME into the refurbished one?

 

They just directly cloned the device. I had some issues at first with some fault codes popping up that didn’t before the swap, so we had to go back and forth. The codes had to do something with an auto transmission, but my car was a manual. Ultimately I think it was their setup, but it finally worked without an codes and have had no issues since.

 

Hi guys, I connected my computer to the car and I checked it with ISTA+ diagnostics software. It gives the same error DME Internal Fault 2BE4.

When I start the car first time, the half engine logo appears on the small dash behind the steering, no engine light on the big dash at the right side.
The idle goes up and down 200-300 rpm. No throttle response on the pedal. But as soon as I turn the car off and start it again, pedal is ok, nothing wrong mechanical with the car.
After that I can stop and start the car no problem until some time passes. I checked all the related fuses in the fuse box. Attached are the screenshots from ISTA.
Any recommendations? Or this is a DME related issue and do I send my DME to ECU Pro guys to let them repair?

 

The gas pedal is directly connected to the ECU but with ecu internal fault, i fear that the ecu is just bad. I can marry another ecu to your immobilizer if you want to explore that option. PM me for details.

 

Did anyone find a fix that does NOT include a new DME?
