Question about 2002 Mini Cooper
I had all kinds of error messages on a 2003 mini. And we changed out the battery. And thats when it started with the codes. I put on a brand new throttle body on and still got the same error codes. So I said to myself this is a computer problem. The battery is right next to the computer and the computer locks down by these plastic clips. So when I changed the battery it must have caught on one of those two wiring plugs that attaches to the computer and pulled it lose. So What I did was push the plug back down and it was fixed. In time these locking clips become brittle and break.

Throttle body issue,is the battery any good try cleaning it with crc spray it's a gray bottle sold at local auto parts store and I believe it's valve cleaner and throtle,try that does car accelerate might need to be reprogrammed but just clean it run it and erase codes

Not sure what your question is? I would charge up the battery with a good quality charger. Most are digital nowadays and usually have some diagnostics available. I mention this because if so you will want to diagnose the alternator as well as the battery performance. One or both might be out of commission. Failing that get the battery to a service center and they can determint if the battery is good. Also investigate the starter relay if both the other two check out good.

pull up the rear seat (the bit you sit on ) , it is held in place with pop fasteners , so just pull it up the way. underneath is a cord with a loop to pull to open the boot catch.

SOURCE: Mini Cooper P1689 code
P1689 - No communication between ECM & Injection Pump Module. This is why it's a hard start and the peddle isn't acting like it should. There's a problem where the (Computer) ECM, isn't making contact with the Injection Pump module. So the computer doesn't know what the pump is doing or sending. Could be a cut in the wires, corrosion, etc.. So many things it could be, fuel pressure is low.

SOURCE: I have a 2002 mini
This could be for several reasons. I believe that the mini cooper uses 2 02 sensors, so it's possible that you have a faulty second sensor.
Or you could have a broken or missing vacuum line or intake manifold leak.
The other possible causes are a bad engine temp sensor, when the temp sensor is malfunctioning the computer may increase or degrease the fuel supply, If you getting a decreased fuel supply on a cold engine then you would have a lean exhaust.I would suggest starting with the easy stuff first, you can use a can of carb cleaner to spray around the intake and on vacuum hoses to seem if the engine picks up and idle or decreases in idle. This will tell you if you have a vacuum leak on a hose of manifold.
IF you can find a leak then I would suggest locating the other 02 sensor and use a simulator on it also.
And lastly if this didn't fix it then a test of the coolant temp sensor and the engine temp sensor would be in order.
