I suspect the throttle body has lost its basic settings for some reason,ive only known of that happening a few times tho,but that is the symptoms of a throotle unit,plug in a scanner check the codes and reset the throttle body in basic settings

SOURCE: vw passat 1.8t battery problem?

Hi

Either your battery has just given up the ghost,........ Is it the original, and now 10 yrs old ?
Or your Alternator is not charging enough, to replenish what is used.

Have battery tested first, if OK, then the alternator belt tension, and alternator for correct output charging rate.

If all these shows no faults, your starter is then suspect.

Good Luck !

A FixYa would be nice thanks !....John.

SOURCE: my vw 2000 1.8t passat has trouble idling. Anyone?

It "might" be your throttle position sensor, look for some electronic's going into your or near your throttle body and clean them with disc brake cleaner, something that won't leave a film on it.
This was the problem with my chevy, I know it not the same car but it's worth a try, cheaper that replacing it.

Check the spark plug for that cylinder, the wire and coil. Also check for any vacuum leaks around that cylinder. See my "How To" on finding a vacuum leak.

SOURCE: 1999 VW Passat 1.8 turbo Code #3 cylinder misfire.

Coils and plugs are not the only things that can cause misfires. Misfires can be caused by vacuum leaks, low compression, faulty fuel injectors, clogged EGR ports (on vehicles with individual ports for each cylinder), blown head gaskets, burned valves...you can spend a LOT of money on parts by just going in and replacing things without diagnosing WHY the cylinder is misfiring.

First guess is that your battery is worn out, a new one will probably do the trick

replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.

99 VW Passat with rough idel


Unfortunately when you disconnected the battery, the ECU (engine control module) forgot the basic settings to run the car. That throttle body code is one of the symptoms. Try your ac if you are in a warm place, the compressor won't kick on, another symptom. I went through this twice already, once because I was putting in a stereo, the other time the battery went dead. Take it to a good VW dealer, call them first to make sure they can do it. I went to one and they said that this was not possible blah blah blah and wanted to install a new throttle body for 750 just in parts! Of course I went to a different dealer. It is a crime. So, call and find out if they can reload the basic settings. I don't know how you will get there if your car is auto, because it will probably stall at every light. Luckily mine is a manual and I could get through it.
Here is a link to explain further.
Print it out and bring it with you, it's helpful for the mechanics.

Make sure you tell them, reload the settings and clear the codes before you do anything else because the symptoms point to mechanical problems, however it is the computer that is fouling the system.
Good Luck.
