check engine light is on then off then on every 200+ miles, fault code indicates Transmission Torque converter. this is common. the cost to fix is $2-3000 for a new torque converter or $7000+ for new transmsission + torque converter.
Regular check engine light when accelerating. For now, cross my fingers and reset the check engine lamp. RPM's slowly increasing in low gears, don't plan to repair the car when the torque converter finally fails.
i have a 2001 audi allroad with 180k miles. problem began when i started having problems backing up my "up-hill" drive way. later my check engine light illuminates. i took it in to my mechanic (the motorworks" in winston salem NC and he advises me that the torque converter has lost some fluid due to a small leak and it causes the light. the only repair he offers is a replacement. parts and labor quote was $3,375.00. that's alot of $ for repairs to a 9 year old car.
