Re: How do you clear the codes in a 1994 Jetta III GL...
Remove the battery terminal for about an hour, when you reconnect put key in and turn engine of a few times engine ecu should reset, but only if there are no actual faults. ( rate me thanks )

Many 1995 Buick Regals have the newer OBDII (On Board Diagnostic version 2) computer. To obtain fault "codes" saved by it, it requires connection to an OBDII scanner. If you have the older pre-OBDII (let's call it OBDI) you don't need a scanner. Read on..
Beginning in 1994, vehicles were transitioning from the older OBDI computer and by a 1996 - nearly all were OBDII. The nice thing about OBDI, was that with a simple paper clip, you could get the OBDI computer to display the code as flashes of the Check Engine light on the dash. No special scanner required. This was more of a benefit in the early years of OBDII - now you can drive to any Autozone (and many other auto parts store) and they will scan the OBDII computer for you at no cost. They can also tell you what the "code" actually means so that you will know why the indicator is on - and just maybe - even how to fix it, too.
If you've been told you have / you're sure you've got an OBDI computer, here's what to do: find the terminal jack - usually under the dash - below the steering wheel. The pinouts for 1995 GMC's are below. You're going to be connecting terminal "B" to "A" (the top RIGHT most two terminals). Check the video on the other side of this picture for full details.
Here's a Youtube video that shows how it's done on a Saturn. It's the same for your Buick Regal - with an OBDI terminal. It will NOT work for an OBDII terminal.
You should check for obvious leaks first, and then get the codes pulled, but you'll need to find someone with a OBDI scanner to read them. Get the code, and come back here-but make sure you are not leaking gas anywhere, don't want a fire.
the fuel filler flap unlocks with the central locking,if you have a problem with the pin not sliding to allow the flap to open,pull away the carpet from inside the boot by the flap and manually pull cable to release....
the vehicle module sees a problem and without a scanner to retrieve the proper codes, it will be hard to correctly diag your problem....best to have a dealer/shop check that first.... GL
1.) Don't do anything. Once the computer sees the engine run normally for a few cycles, it will automatically clear the code.
2.) Connect a scan tool to the OBDI port to clear the codes manually. Local auto parts stores will often perform scan tool diagnostics free of charge.
3.) If you want to remove the code quickly without any special tools, just disconnect the battery and leave it disconnected for a while. (How long varies for different cars, as some engine PCM's have capacitors that hold a charge for a short while after losing battery power.)
Sounds to me you blow by. Thats when either rings on the pistons are worn letting oil pass by or you have a scorned cylinder which also is letting oil get by. Should get a compression check done to make sure.
