Hi guys,

So I have a JCW working fine with the racechip ultimate, for 2K miles, roughly.

I just saw a check engine light coming, after a stall I think (It's a manual).

The code is P12a4.

I feel the car is less powerful than before.

I thought I could remove it with my OBD wifi and iphone app (dashcommand and four stroke).

Turns out, I can't.

What do you think?

Do you know to what this code is linked?

Only solution = Dealer?

Any experience from someone with this code?

Thanks a lot.

 

I had that code before and was due to a fault pressure sensor. I believe it is fairly common on the F56. I would just remove the Racechip and if you still have a warranty Mini should replace it no issue.

 

For removing the code, I use OBD Fusion and my wifi dongle

 

Reseat the Racechip connectors.

 

what does that mean?

disconnect / reconnect?

 

 

Call or email RaceChip before spending $$ at the dealer.

See if you can get a parts shop like Autozone to clear your code for free.
I found out an old plugin hardware scanner seems to clear codes easier than phone apps.
