i have a mini cooper s 2007 with 90k miles 6 speed manual and jcw tunning kit

the car was parked for about 5 days and it took me about 2 trys to start the car early in the morning so i drive about 20 miles and out no where the cart went off so i have to pull l off and never start again (towed to home)

a mechanic with a scanner came home and He test the fuel pump, spark plugs, coils, battery and everything is ok the only thing he sees on the computer is the following codes: D904 “car access system: K-CAN line fault CAS/EWS and A0b5 which is speed sensor according to him so he told me we need to test the car key before anything else but I will have to tow the car to his place and pay him about $150 so that is about $400 just to test the key

Is there anything else I can do? Or maybe buy a brand new key from dealership (I only have 1)

 

Sounds like your mechanic tried to diagnose the car over the phone and thinks its the key. I would advise finding a MINI specialist and taking the car to them and just having it diagnosed. We get people call us all the time wanting their car diagnosed over the phone and with all the variables you can't know until you see it. And keys rarely go bad so that would be far from my first guess even with an EWS fault.

 

Where in NJ are you?

Other than pulling codes, what else did you try doing?

Do you have a sunroof? Checked for water leaks?

Did you check relays and fuses?

 

thank you for your help! Im located in Bayonne, nj

I did check fuses/relays under the hood and passenger side all good y also check battery voltage, hpfp, and they all good

i had a sunroof leak a month before this happen (passenger side) and i fixed and dry matts and car was find running ok till now

wondering if there is a way to check the key?

 

Checking the key isn't something I would know. However, since the car is locking/unlocking and cranking, it makes that hard to diagnose. Also, there is no code that is leading to EWS - Key alignment.
Since the fuse box got water in it a while back, is it possible this time is the same?

I might be going to Patterson over the weekend with the wife, I might be able to swing by if your close to that area.

 

That will be great! But i think is far (50min on car)

the mats are dry so i dont think that is the case the on code code are this

 

after a few days of research and find out that i can do a extensive read of my ECU with INPA I installed and find the below error codes. does eny abody know whats causing th

e K_CAN LOW error? D904

 

Was there ever a fix for this error?
