You can click on the VW symbol to get VW unique codes.
Unfortunately, it doesn't give much information on the problem, except:
P1256 Engine Coolant Temperature Sensor Open/Short To Positive
So it could be a bad temperature sensor, or a wiring problem?

    It's a bad temperature sensor. Order a new "Green Top" sensor from or an alike source.

run the fault codes to find out why the VSA light is on and get the codes for the misfire

I've been told theirs 9 eng. coils in my 2000 ford Exped. I've only owned for 2 yrs. When you get a tune-up do they replace all the coils at once.

should not replace any coils unless the fault codes reports a misfire or associated problem
Here is a news flash for you
EFI cars have a tune up done every second it is running as the ECM keeps the engine at optimum performance
You only need to pay it attention when the codes report a fault
You don't even have to replace the plugs if it is running all right

PO 171 and PO 300 CODE GMC ENVOY

the sensor to replace is the HO2S sensor which is different to an O2 sensor. (has a different function)
code p0300 is random/multiple misfires
as misfires are from the electrical components you did not pay attention to items like low fuel pressure and faulty injectors which also cause random misfires.

Saab code p1256

That code generally refers to a problem with the engine coolant temp sensor not giving the expected temperature to the computer within a specific amount of time if I remember correctly. I could be wrong but I think if you replace the thermostat the car will warm up faster and once you erase the code it shouldn't come back. Not a bad idea to replace that part anyway as part of regular maintenance and it could save your engine's life. Cheap part ($10-$15 bucks) and fairly easy to install on most vehicles. Might not be a bad idea to install a new temp sensor while you're at it, they do fail and are not very expensive either.

P0118 code

Make sure you didn't accidentally unplug the ECT sensor or damage the wires. If visual inspection checks out ok clear the code and verify it comes back. If it does probably need a new sensor and or thermostat, pay attention to your temperature gauge. If it acts erratic or definitively different then normal, most likely need a thermostat. I usually just replace both and be done with it.

I have a 2005 Dodge Ram 1500 5.7 hemi. I have to replace the EGR since erasing codes numerous times has not helped. Do I need the PCM flashed after replacement? Thanks

Hello! No, not at all...After you change the EGR, disconnect the + battery terminal for 3-5 minutes...Reconnect...And if the EGR was the cause of the fault the code will clear...Make sure you have the stereo code...If not, connect a regular 9 volt battery to a cigar lighter plug (pay attention to polarity)...Plug it into the cigar lighter socket before you disconnect the battery...It will maintain power to the stereo...Guru...Saailer

I have a 1995 dodge neon that has the service engine light on and I do not know what to check or replace.i do not have a maintenance manual and cannot find one for free.

hers what you do. grab a pen and a piece of paper. go out to the car and turn the ignition on, off, on, off, on. the engine light will begin a series of blinks. you have to count the blinks. all of the codes are double digit so you will need to pay attention. it will blink however many times for the first number pausing briefly between the will pause longer between numbers then blink again for the second number again pausing briefly between blinks for instance. say the car has a code 55 which it will. it will blink 5 times pausing briefly between pauses then there will be a longer pausethen it will blink 5 more times pausing briefly between numbers. jot these numbers down paying close attention to ensure accuracy and if you reply to me with the codes i will tell you what they are. you can check the codes however many times you need to
