Hello all and especially Brett,
While going to a 4th of July party the dreaded Check Engine light came
on in my 1993 XJ40. When I stopped and checked the code it was a FF37. I
reset it, and it did not come back. Now on a sunday afternoon drive to
the grocery store the Check Engine light comes on again. I check the
code and it is the FF37 again. I reset it and this time it comes back
immediately. I then checked my personal archives in the fault code
section and found 2 e-mails that Brett had posted concerning FF37 and
how it is an electrical fault with the EGR solenoid. I looked up the
price on the web and decided that before I spend $80 I better try
Brett’s recommended cure. Clean the dirty connection. It appeared clean
to me but I gave it Brett’s famous WD40 treatment. Clipped it back into
place, cleared the code then started the car. Viola!!! No more check
engine light. Problem apparently solved.
So Brett, if we ever cross paths, drinks are on me.
Thank-you,
Tom Souther
