Your regional distributor might have a loaner dongle available, perhaps inquire with your nearest service center?  ( see https://dealerlocator.flyrotax.com/ ) 

Nearest one is about a 9 hour drive. I found a repair center I will try to call tomorrow that is only a 3-4 hour drive. 

Wow, nine hours drive is harsh!   

FedEx overnight would be way cheaper. (Typically you call with your credit card, pay the owner a deposit up-front on the loaner dongle, and they settle the shipping costs when you return it...)

Got lucky and found a guy 30 minutes away with one, isn't a gentleman on the Rotax site I just got lucky! The gentleman has no idea if it's a level 1 or level 2, I'm guessing once I pick it up from him tomorrow that it may have some writing on it alluding to which it is? 

Is there a good place I can go online to get a copy of the user manual / guide for it?

Thanks!

On this website, Rotax owners.com, there is available a video demonstrating how to use the BUDS program with a dongle. Be aware that the video was made using the old version of BUDS, You must first install the BUDS  program on a suitable computer. It is available from flyrotax.com. However you will be downloading the latest BUDS version and parts of it will present different screens than the video. But the start up procedure is about the same for both versions. The best screen to see issues with the engine is the health screen. Once on that screen the engine can be started and sometimes a fault will show up, giving a basic idea of the problem, But the best procedure is to extract the files and get them to a Rotax certified technician who has access to the BUDS reader program.

Wanted to update everyone as I am still having issues. I sent my logs out and received this reply

"I took a look at the logs and saw the spark plug boot event.  No problem as that should be fixed.  I see an ETPU synchronization error there as well.  This is usually related to the ECU or Crankshaft Position Sensors.  Take a hard look at the CPS wiring near cylinder 4 to make sure it’s not burned or chaffed.  If you run the engine again can you get another flashing light?"

I was told to have my mechanic cut the corroded part of the spark plug wire going into the one boot. He refused to do so. I ended up having to spend $1,100 to get new wires installed! A $233 part and a lot of labor.

I took the plane home from the airport I serviced it at and had no light occur during 45 minutes of flying. Today I went out to make a 2hr XC trip at night and about 40 minutes into my flight I had the Lane A light turn back on and the ROTAX Land Aircraft Immediately warning pop on. At this time I had no loss in power or did I feel anything different at all. I made a diversion to a different airport and landed. Started the plane and did a run up and noticed a 100RPM jump when doing my lane check. The lights cleared so I decided to proceed forward, by the time I taxied to the end of the runway the light came back on with the warning to land the airplane. Given that I had no engine issues I decided to take off and return home. 

I'm a little frustrated as now I've had to ferry the plane to another airport to have this worked on 4 different times with no luck. Does anyone have any other ideas that I can look into?

Thanks so much everyone!

This is an ECU controlled engine and reading the ECU Files is the way to find out what the issue is.

As you have already experienced, the beauty of the engine is that many failures have absolutely no effect on how the engine makes power.

Most everything has a backup that keeps it going despite any failures.

The key is to NOT ignore the Warning Lamps just because the engine is running Just Fine!

You have had additional warnings that may very well be the same issues you have already seen.

You will need to download the log files again.

You can view the log files yourself by clicking the Logs tab.

If you cleared the logs the last time you were in there, only the most recent faults will be showing.

What were your findings concerning the Crank Position Sensors? (Again there are 2.)
