This is a 2002 Audi A4 1.8T Auto.

While fixing the vacuum hoses I broke several other things (vacuum T's, other houses, the orange housing for the oil measurement tool, coil plugs, etc) everything was very sensitive in this engine, like if the whole car had overheated and all the plastics in the engine bay got burnt.

Using this B5 Diagram I will mark the items that were replaced today. After these items were replaced this car ran like the first day that came out of the dealer, however, when I stepped on it and it felt like one piston stopped working and the check engine light came on. One of the things that broke was the orange plastic that houses the oil measurement tool; I tried putting my finger on it but the car still idled very badly.



The idle was very rough, I pulled the coil closer to the front of the car and it made no difference (bad coil or plug?). I turned off the car and switched coils (to check if the coil was the problem) , I started pulling coils again to check the rest of the cylinders until the car died and now it will not start again.

What did I do wrong? I normally pull the coil or plug to check for faulty coils or spark plugs -- was I supposed to check in a different way?

[Things that are still broken]

* Orange plastic that houses the oil measurement tool, broke very close to the engine block
* Two plugs that go to the spark plug coils also broke, the plastic broke inside where the female connectors go.

 

Sounds like you have a bad coil, you need to check your codes. The dipstick tube is no big deal, they break all the time and wont hurt anything. Go to a vw dealer and they are like 5 bucks. Just be careful to not get any of the broken plastic down in the tube.

I dont know what to tell you about the coil connectors. Do they seem to still be making connection? That could be the problem, but start by checking the codes.

Are you sure you should be working on your own car? You have to be more careful!

 

I tried to be careful with the car but for some reason things were just breaking with a soft touch or a bit of movement.

The coil plugs seem to be making a good connection, however, I still cannot understand why the car would not start any more.


Tomorrow I will check the plugs.

 

One time, i had a coil or 2 break and it caused some of the wiring to melt, so the car wouldnt start. Had to be towed 2 hours to dallas that time.

 

Jesus, where exaclty did they melt?

 

Not sure, the dealer fixed it.

 

I fixed it. Three out of the four coils were bad.

Thanks for your help shane.

 

Glad you got it fixed. Try leaving your engine cover off, i have a theory that leaving it off helps the coils stay cooler, which makes them last longer.
