Most liked posts in thread: Reading Fault Codes

If you get a Check Engine Light (CEL) then a sensor is detecting something wrong and generating a code.

To read the code, you need a scanner, or you can go to a local AutoZone who will read the code for free. They hook up the scanner to a port under the driver's side of the dash, and that scanner reads the fault and displays the code.

The code probably won't tell you much by itself, and you'll need to refer to a list to find out what it means. There is a list of the codes on this site, and books like the Bently Service Manual for your car will also have a list of codes.

 

A Peake Research code reader (plugs into OBD port...the same place the state guys plug into at annual emissions time) coupled with a Bentley manual to tell you what the codes mean has served all my needs for the past decade maintaining my 2004 Mini Cooper.

I would suggest anyone with a Mini Cooper who intends to maintain it themselves needs these two essential items.

 

Hello to you, I am new to the site and new to owning an R53 Mini Cooper S. Before I bought it, I test drove it and scanned it with a standard diagnostic scanner and it came up with no DTC codes. However, I noticed when the car got warmed up, it would hard shift from 1st to second gear and hard shift down from 2nd to 1st gear.

I reset the ECU and that didn't help so I decided to invest in a more thorough scanner and purchased an Autel Maxidiag Elite MD802. After doing an all systems scan with the Maxidiag it came up with a fault code: 3330 NOT PRESENT EGS Shift Respone S1. I've search the many different threads an couldn't find anything relating to this code. I'm wondering if it's a sensor or something that can be reprogramed
