Greetings from Peake Research!

So many of you already own our tools, and a bunch of you may have just received them during the holiday season. Thanks so much for choosing our products. To help you get the most out of your purchase, we've prepared some basic thoughts and tips on how to approach the results your Peake Tool provides.

Unlike generic (OBDII) readers, you Peake Tool reads the exact same fault codes that a dealer or technician sees. These 'factory' codes are what BMW intended to be used for pinpoint analysis and repair.

It's important to recognize that the codes are merely the first step in proper diagnosis. Most factory code definitions include very detailed information, and may even name a specific component or sensor. This does not necessarily mean that that part has gone bad. For example, the sensor in question may be ACCURATELY reporting a problem within the system it monitors. Save yourself some time and money by resisting the urge to blindly replace parts just because a fault code mentions them. Put on your detective's cap and start gathering more information.

Here are a few suggestions on how to handle your next code encounter:

1. Record, Reset, and Retry: Your Peake tool may be revealing old codes that aren't currently an issue. Jot them down, clear them, and see what returns after driving normally – these codes indicate the problems you should be concerned with.

2. Signs and Symptoms: Notice anything unusual lately? Things like hard starts, poor acceleration, and decreased fuel economy are all real-world clues that may help make sense of the problem being reported by the fault codes.

3. Look, Listen, & Feel. Open your hood and look closely. See anything unusual - leaking fluids, cracked hoses, disconnected wires, etc? Pay close attention to components the code(s) may have mentioned by name. Start it up and listen – hear any whistling, ticking, clunking?

Armed with the Peake code(s) plus all that you've observed, you're now ready to make some educated decisions. It's always wise to start simple. (fixing the obvious issues you encountered in your examination won't hurt either...) Depending on your level of experience, the solution may be obvious, or a total mystery. Hit the web, open a service manual, or consult with other forum members to figure out what comes next. If the answer is still not clear, spend your money on professional service before you start the ever-popular cycle of trial-and-error parts replacement.

It's easy to see a quick return on your Peake Tool investment, provided you keep a level head throughout the diagnostic and repair process. Hopefully, these suggestions will serve you well the next time an engine warning pops up.

Thanks so much for reading this, and for your continued support.

Ken

Sorry for the stupid question, but how do you know which tables to use to interpret the codes after they are pulled?

Example: Is an "08" code a "misfire w/ low fuel" (table 0b) or "air mass sensor" (table 15)?

When u plug in the tool and run it, the first number that pops up will be the one that tells you which table to use. Then the following numbers are the codes that it is reading off your car.
