Peake Research Tool

[JasonMHorn]

Has anyone ever used the Peake Research Scan Tool for their E39? If so, how do you like it? I have one for my E36 and I really like it. So I was thinking about buying the adapter so that I can use it on my 2002 M5. Thoughts?

Rather than buy an adapter, I bought a male ended OBD-2 cable with loose wire ends off amazon for about $8 and then cut the female round 20 pin connecter out of a car at the local pick a part. A little bit of soldering and I have an adapter for less than $15 that works great. The peake tool itself works well on the E39, I was able to scan codes and reset service and check lights. So for minimal expense you get a lot more diagnosing and clearing ability than a plain OBD2 code reader. DIYs are plentiful for building a cable also.

Build or buy: that's the conundrum. Time is money. He may not wish to run around looking for parts and then fabricating a kludge.

Any chance you have a link to the cable that you purchased and a diagram for the wires that were soldiered together?

I don’t mind a little bit of work as long as it works and I can save money to put into the car.

Ok so I was a dollar off. I figured it was easier to cut a female round pin out of a junkyard car than to try buying the part from the dealer then have to pin and wire it. I used the links Shogun posted to build a cable. Here’s the link to the OBD plug I bought from amazon.

Obviously this will require a multimeter to find the specific wires and pins you want to join, and a solder gun. I also did this because I could prime the OBD plug and build a cable faster than I could get one delivered to my doorstep.
