LAUNCHX431 PRO5 Diagnostic Scanner with SmartLink C V2.0, J2534 Reprogramming Tool with ECU Coding, Topology Mapping, 60+ Reset Services, Intelligent Diagnostics, Guided Functions, 2-Year Free Update

I purchased this automotive tool to use on a 1991 BMW M5, one of those few almost-antique cars that are appreciating. This model year of 1,623 imports is the last year that BMW's M-racing division hand assembled the engine and race-developed components that turn a stock BMW 5 series into an M5. At 3.6 liters, the engine produces nearly 100 brake horsepower per liter. That is Ferrari-type territory. Co-developed with Bosch, its digital engine management electronics (yes, this is early 1990s...) play a key role in this feat. I'm looking at over $20,000 should I mess up the electronics. Fortunately, my past work experience at a BMW dealer resulted in the knowledge of the correct tool to "talk to" the electronics. Peake Research offers two reset tools designed specifically for BMWs of various model years oil service lights only and this one.You can buy the Peake tools direct at full retail plus shipping. The same tool rebranded with a popular BMW parts distributor's name is available at full retail and free shipping for orders exceeding $150. Amazon delivers the Peake labeled and warrantied tool with a small discount and free shipping to its Prime customers.I ordered it from Amazon on Labor Day. It arrived Thursday exactly as predicted. Within two minutes, I had just recovered $90 not spent for a BMW oil service / service indicator reset. One more use and I've passed the breakeven point!But wait! It gets even better. This R5/FCX-3 also reads fault codes. A dealer or aftermarket shop may charge you $150 or so to scan the codes and provide you with a repair order. Unfortunately, I've encountered smaller urban-area shops that are less than honest or simply inept at diagnosis. Now I'll know exactly what is needed. Armed with that knowledge, I can assess the quality of a potential repair shop if I cannot do the work myself, very likely on this complicated car.For the older BMWs, there is yet another benefit to having your own code reader / reset tool. The sensitive electronics operate from very slight electrical currents. Older cars often develop shorts or corroded connections that result is false readings. The read fault code points to the area for you to look. You may find a loose wire or defective sensor easily replaced. Or you can simply erase the fault code and see if it returns. Tip, you can disconnect the battery negative terminal for a few minutes to accomplish this. You will need to know how to reset the clock and radio codes.If you can drop your oil and replace an oil filter, you can do this too, in minutes!Peake Research R5/FCX 3 BMW Scan/Error Reset Tool 87-00

I tryed contact after sales for the smart box 3.0 after buying this but never sent me the link or anything so I can’t use the smart box on my laptop to programs vehicle with it

Product design and size is very handy , diagnostic speed and connection time with Bluetooth is excellent, done most of the functions we need in repair work every day

A must have tool for BMW enthusiasts. Worth the extra cost to get this model as opposed to the model that just resets inspections and the air bag light. The extra adapter cable that is available (which I already had) allows use on both older and newer BMW models. Casing of the tool is plastic (would have liked it to be a bit more durable, but not a big deal) and the carrying/storage case makes for easy storage in glove box, trunk or tool chest. The book of codes that comes with it is pretty good overall, and further internet research can save you big bucks on repairs, especially if you DIY or bring the car to the dealer knowing what to expect. Highly recommend.

I have had this scanner for a month now and I am very happy with it. I have worked on several different vehicles with it and I am amazed at what all you can do with this tool. It has saved me so much time and money. The capability of this scanner is so vast. It took me a little while to learn it but it wasn’t hard to figure out. I would highly recommend this scanner to anyone.

This product was somewhat difficult to master but it did eventually give me codes. There were not enough instructions on how to reset the oil light and check engine light and the instructions were a little vague. It did arrive quickly and I have no complaints about the shipping. It did diagnose a bad catalytic converter which is a tough thing to diagnose without a sophisticated electronic vehicle monitoring system like the one in my BMW. I suppose for the price compared to a Snap-on code reader, it's a pretty good deal. I was expecting more however and I'm not completely satisfied. I'm hoping my point of view will change after I use it a few more times.

Don't buy this scanner, it's useless. They never answer to complain!

I've had the pro 5 and the pro 4 elite, amazing tools to own.
