The recently acquired ‘03 Vogue TD6 (145k miles) has been nothing but trouble-free joyful motoring (not) :mrgreen:
Backdrop/preamble:
Started out with an array of HDC/ABS related warning lights. Purchased the RSW scanner tool and resat the various of codes across most ECUs. It seemed most were trivial and likely attributable to voltage drop and/or the battery going bad (i.e. repeated disconnecting, jumping, charging, etc). I replaced the battery with a (provisional) 50Ah (small) battery and the car functioned like it should (free of any warning lights) for a couple of weeks.
Then the key remote stopped working, and about a week later the main battery suddenly was drained overnight (down to 5-6V). Upon charging the battery (while connected), a relay (?) started going frantic from inside the “E-box”. Disconnecting/reconnecting the battery solved this.
With the battery freshly charged (12.5V), the car now won’t start/crank. Tried a different battery as well as jumper leads from running vehicle (charging @ 13-14V) to no avail.
Both keys turn fine through all ignition positions, but there is no cranking action or click from starter relay/solenoid (nor that electric jerking sound from insufficient voltage or bad ground). Column lock disengages and all other power functions seem to work.
I have two sets of (fairly worn) keys, both work/turn in the door and ignition. One key (the least worn) have had working remote central locking, until recently. Checked battery condition in both remotes and voltage checked out fine (done within the 2 minute (?) window necessary to avoid resyncing). I guess there should not be any causality between central lock and ignition/immobilizer, as I understand the immobilizer transponder works independently from the central locking system and its battery? There are no codes stored on the immobilizer ECU.
Also, having attempted the resyncing procedure for the keys (dozens of times), all I get is ten flashes from the remote’s red LED. No confirmation from door locks. No information in display other than acknowledging11 the key when inserted (‘key in ignition lock’).
Checked all fuses (glove box and quarter panel) and tried to “wiggle” the shifter (i.e. back and forth between D, N and P) while attempting to crank in order to test neutral safety switch. Also tried pulling/reconnecting fuse #18.
Any advice is highly appreciated!
