In another thread, concerning OBD ports, it was suggested that some problems were caused by a partial failure of the ignition switch. Perhaps my X might have the same problem (amongst the growing list of things gone wrong lately).
Since I have had the X, I've had occasional problems with my Foxwell not being able to read all modules when scanning, the key having to be flipped and reinserted before it would crank, and the EWS losing track of my only key...all of which may point to an intermittent problem with the ignition switch.
Since mid-October, when my X died (fuel pump), and I have had the additional problems (as listed in the preceding paragraph), I have ordered a valet key, which should be able to crank the X and not get "lost" by the EWS, assuming that it is recognized by the EWS (does the new valet key need to be programmed into memory?? I have not read anything concerning that). The valet key has arrived at the dealership, but I'm really ill and haven't been able to get there, yet, to pickup the key, so maybe it's time to rethink my future steps to fix my X.
1) does the valet key need programming into memory? can my Foxwell NT510 do that?
2) if the valet key has the same intermittent problem as the OEM diamond key, then is the ring antenna suspect, or could it be the ignition switch failing?
3) once the above 2 have been solved, and the valet key works, then I'm cutting the diamond key open, and will resolder the board, replace the battery, and transfer the guts to a key shell I already have (blade is pre-cut), and hopefully it will work like new
4) if new and refurbished keys are working, antenna ring and/or ignition switch have been replaced (or not), and the X cranks every time, again, then
5) pull the new $160 Hella fuel pump, insert the cheaper (but free to me) $70 fuel pump, and see if the X can take sharp corners and curves without fuel starvation.
Like I stated in my previous post, this process may take awhile, and perhaps take months, so unfortunately, my X5 has become a true "project car".
If my present cold? doesn't kill me, I might be working on it again next week.
Wish me luck.
