battery replacement problems
 

I have just replaced a dead battery in my 4cyl. 99 Passat , the check
engine light is on, and the car idles rough and of course I can't
drive it like that! I guess the memory has been erased! and I kind of
need it back.
Thanks

battery replacement problems '99 Passat 1.8t?
 

Lost its mind huh? ;-)

When you installed the battery did you turn the ign on and wait a couple of
minutes before starting the engine?
This might have performed a Throttle Body Alignment.
If you have a tool like the ross-tech.com one then

At least you need to know why the engine check light is on. ;-)

"Warm the engine up. Disconnect the battery for 10 minutes. Re-connect the
battery. Switch on the ignition for 15 seconds without starting the engine.
Then start the engine and leave it ticking over without using the throttle
for 5 minutes. Test drive it using various throttle openings for 15
minutes"

Anyone got a Bentley manual for this 99 Passat? Surely the procedure
for replacing a vehicle battery and getting all of the electronic
modules re-synched and initialized would be covered in that manual?
