BMW Service Reset Tools & Fault Code Readers for BMW 3 Series E90 (2006-2011)

Clear BMW chassis

Please ensure your correct model is selected

Fault Code Readers and Diagnostic Scanners put the power of the dealership in your hands. The Check Engine or Service Engine Soon light means something! It's alerting you to a potential problem and a fault code has been stored in the car's internal diagnostic system. You can take the car to the dealer and have the code pulled for you (for a one-time fee) or you can buy one of these code readers and check the trouble code yourself (and any other code that may come up in the future). These diagnostic tools pay for themselves. They are a must for the DIYer or any mechanic. These tools can read and reset trouble codes and reset your maintenance interval settings. A separate tool can also be used to reset the SRS system (separate from the engine diagnostic system). Peake Reset Tools come with a booklet containing instructions and a list of codes.

For newer cars we also sell multi-function scan tools, gauges, and programmers. Reading and resetting Diagnostic Trouble Codes (DTC) are some of the many functions that these handheld and dash-mounted accessories perform. These are the next generation of 'smart' programmers capable of loading new versions of engine software, recording and playback of data, and timing meters.

The Cobb Tuning AccessPort is a flashing tool that installs performance software through the OBD port on your car. No other software is as easy to use and install! If you can program a TV remote, you're over-qualified to install this software. Just plug the AccessPort into the OBDII port under the dash, bring up the AccessPort onscreen menu, select from a variety of engine maps for your desired performance and install. It's that easy. The software is from COBB Tuning - one of the most accomplished software tuners in the business. The Cobb software replaces the conservative factory settings with different maps to make more power.

The AccessPort maintains the sophisticated control logic, refined engine response and excellent driveability of the stock BMW computer while providing impressive power gains and improved performance. Pre-loaded on the AccessPort are engine maps for 91 or 93 octane fuel, and a valet mode, with the capacity to hold up to 100 other tuning files! The AccessPort also saves your stock tune for you to revert back to factory settings at any time. It also has the the ability to download additional maps so that you can run various upgrades with the correct software tune. Additional tunes are available direct from Cobb through their AccessPort manager program (available for PC or OSX). Cobb also provides tech support.

In addition to the performance improvements, the AccessPort includes a variety of other useful tools -
+ performance measurements
+ data logging - up to 10 hours
+ fault code/DTC reading and clearing
+ check/verify performance modifications - measures 0-60 and � mile times and can measure approximate HP

The AccessPort can display boost pressure, oil temperature, pedal position, load, individual cylinder timing, and other engine data channels with the Live Data feature.

The Cobb Tuning AccessPort is a flashing tool that installs performance software through the OBD port on your car. No other software is as easy to use and install! If you can program a TV remote, you're over-qualified to install this software. Just plug the AccessPort into the OBDII port under the dash, bring up the AccessPort onscreen menu, select from a variety of engine maps for your desired performance and install. It's that easy. The software is from COBB Tuning - one of the most accomplished software tuners in the business. The Cobb software replaces the conservative factory settings with different maps to make more power. But it's more than just a way of loading performance software... The AccessPort also functions as a data logger and fault code reader . It's a multi-function tool that you will never get tired of picking up and checking out.

Data
Since it plugs into the car's OBD communication port it has unparalleled access to a stream of engine data. It reads and displays throttle position, boost, ignition advance, wastegate duty cycle, mass air flow, intake air temperature, air/fuel ratio, calculated load, and much more. You can also record data for later analysis - up to 10 hours of running data! It also works as a timing meter for 0-60, 1/8 mile, 60' acceleration, 330' acceleration, and 1,000' acceleration time. You can plug the AccessPort into a PC or Mac and view all of this saved data in their program. This information is invaluable for evaluating engine performance and performance modifications.

Diagnostics
With access to the OBD port, the Cobb tuner can also read and reset Diagnostic Trouble Codes (DTCs). This saves you a trip to the dealer or local shop simply to have a fault code interpreted. Now you can pull these codes and get an answer to the problem right away! The code number and a brief description of the code is given so you won't even have to search for it online. Reset the code and you're on your way (unless the code comes back...).

Power
The AccessPort comes pre-loaded with 4 tuning files - Stage 0 (stock), Stage 1 Sport (91 octane), Stage 1 Aggressive (93 octane), and a Valet file. Additional files are available from the Cobb website for things such as an intake and larger intercooler. It can hold up to 100 different tuning files! It also saves your stock original file so you can revert back to stock at any time. The AccessPort maintains the sophisticated control logic, refined engine response and excellent driveability of the stock BMW computer while providing impressive power gains and improved performance. Cobb engineers are constantly revising and tuning their files to extract the most horsepower with the least effect on reliability and drivability. Updated files and new maps for additional modifications are available direct from Cobb.
