I have searched thru the threads, and seem to go in circles. Here is the car, the symptoms and would appreciate any direction on accurate diagnosis:
2005 Jetta TDI (new Jetta) bought new in 2005 for high school aged son who drove it for 12 years
Bought back from him last year with electrical issues as follows:
1. battery won't stay charged; dies overnight-had to be jumped to start
2. now, it will not crank when turning key and cannot move shifter out of Park (I removed the starter solenoid wire and jumped it with trigger switch and it does turnover/crank, just does not start; also, while turning key, electrical dash does come on and the amber icon of a steering wheel is what remains on along with a bulb showing out (but don't see a bulb burned out?)
3. a/c has not worked for awhile (may be unrelated) but radio does come on
4. drivers door has at least 1 wire that is severed
5. when I remove the positive side of battery terminal, there is a good deal of sparking both on removal and on placing it back on the battery (assuming this means I have a ground short somewhere but don't have a clue where to start with this)..
Prior to the full blown inability to start from the key switch, I could jump it with a battery booster and it ran great (has the rivet failure looming in the dry clutch which needs to be replaced but is unrelated to electrical issue). The sounds from under the hood when you turn key on (assuming an electrical fuel pump) sounds now do not come on.
My questions:
a. does this sound like a 109 Relay failure?
b. does this sound like a key switch failure?
c. does this sound like a ECU failure? (where is the ECU on these models?)
I've worked on old cars, carburetor inboard v-8 gas boat engines, my sailboat's inboard Perkins diesel engine and am of decent mechanical capability but I am not good with electrical issues... need help as wife wants to junk it, I want to make it a daily driver!
Thanks,
