    I was 10 minutes into a 250 mile trip. Slowdown 1-4 comes on for 20sec and car goes into limp mode. Light goes off. Stays in limp mode for another minute. Resumes running perfectly and continues for entire trip. What the hell was that?!! Never had a cel or any problems whatsoever for the 2 1/2 years since purchase. Do I need to be concerned?

    Thanks for your help. Love the forum! Learned a lot.

    Hi,
    I got this SDL and limp mode on the 1-4 bank. After a while, the bank came back again. This happened more and more often, till I replaced the thermocouple and CAT ECU. After a month, same thing happened on the 5-8 bank…..It’s a 5 minutes job to fix.

    On a 48 you can pull the plug on the sdecu and delete it and its effects as long as you know the sdecu issue is a ghost. Otherwise you could have a real problem.

    Thanks all. If it happens again I'll check the cat temp and if ok disconnect.
