Erratic Ignition

why not let them fix it?
warranty extends with not solved problems in warranty
at least here in USA the laws are clear, on that.
first off, never take a car that runs prefect to be fixed.
or with no DTCs present.

if wanting to be part of the solution get a scanner,
and scan the PCM full time and see all those errors.
DTCS at the fail time.

if not, you will never ever fix it.
cant fix , not broken, no ever.
you must catch it. see?

erratic ignition.
does that mean gross engine misfire.?
or the dash lights (ignition) goes dead.
Tachometer bouncing,(have one)
other gauges acting odd.
engine stalls?
too low idle speeds.

i can list 100 causes. I wont.
only tests work, ONLY.
get the tool and use it , ask if unsure to turn on a scan tool.

V70 windshield washers erratic

You have plugged hoses or nozzles. You can get a filter to put in line after you clear all the parts. You have some sort of particle floating around in the system causing the erratic failures.

Where can I find the electrical specs? the blinkers both stopped working. The hazard blinkers do work.

Any other strange electrical issues? Headlights, blower, wipers?
Its quite possibly the ignition switch. Just had to replace it on my daughter's 97 jetta. She had first the blinkers behaving erratically, then it was random electrical issues after that. At first we were sure it was in the combination switch, or the arms off the steering column that operate the blinkers, wipers etc. Unfortunately, that change didn't fix it. After a bit more research I learned the ignition switch on these creates these symptoms. Changing the switch wasn't very difficult with a diagram and a bit of experience and the part was only about 30.00.
Hope I've helped -Good luck!
