Question about 2003 Volkswagen Golf

Open Question

Check Engine Light Blinking

I have a 2003 VW Golf and a few months ago, the same thing happened. The mechanic said it was running on only 2 or 3 cylinders because one a spark plug needed to be replaced. I had a full tune up (spark plugs, wires, filters, etc.) and a month later, it happened again. This time, the car had been sitting for a few days and the weather had been cold, rainy and then warm and cold again. It didn't happen again until today, during a snow storm. I put some dry gas in it and it seems to be fine. The check engine light has been on for quite a while (o2 sensor needs to be replaced), but this shaking/engine light blinking problem has happened at least 1x a month, but only for the last 3 months.

    This happened to me yesterday... light started blinking and motor weak... but I needed to get somewhere ... light eventually stayed lit and persists... weather had been cold/snowy then unusually warm... lots of water snow melted on car + rain. 


    Today is cold/ice...light still on when cold-started....will try fuel, oil/fluid change, I like the spark plug idea!

SOURCE: 2003 VW Golf - O2 Sensor?

Honestly it is not very expensive to replace, but it is not extremely important. What it does is measure the oxygen/fuel level coming out of the engine. This tells the computer that the engine is either using the right air/fuel mixture or allows the computer to change the mixture slightly to allow the car to run properly. You could pull the sensor out and clean the terminal as it usually has alot of carbon build up due to its location, but this is normally a temporary fix. I hope this helps you with your problem.

SOURCE: 2003 VW golf o2 sensor?

Yes, it could be something else, other than the converter, such as a faulty o2 sensor. Take your VW to Autozone or Advance auto, and ask them to a do a scan, to see what they come up with ( think it's free).

It is tough to tell without looking at the engine, but I would recommend checking your spark plugs. If you hear a chugging, at least you know that your fuel pump is working. The gas sounds like it is not being ignited properly. Hope this helps!

What color is the smoke? White smoke is oil burning, black is fuel. There are a dozen things that could cause the symptoms you describe. Faulty fuel pump, dirty injectors, ignition system fault, cracked cylinder head, bad fuel, faulty engine sensor (MAP, OXY) etc. Really need to find a mechanic who can look at it in person.

Hi. Please check the spark plugs, if worn this can happen. Also if the injectors are leaking into the cylinders. This i have seen only once in many years on the 2003 GTI.

Engine Maintainance light on


This could most likely be one of 2 things, 1. if it is your maintainance light, it is probably one of your sensors, possibly the mass air filter sensor, oil pressure sensor, and 2. If it is a diesel engine and its the glow plug light, you would need to replace your glow plug relay because it telling you that the glow plugs are still on when the engine is running, which you should take care of asap before you have to replace the glow plugs themselves.

My golf tdi estate


Well, there are some hundreds reasons why the engine can stop. Common ones are:
Dirty fuel filters, problems with electronic distribution, spark plugs to be changed, broken fuel pump, battery contact not in place, blown head gasket, rarely also a problem with anti-theft alarm motor lock can cause same thing.
Generally, if the car motor stopped immediately, with no additional symptoms is likely a problem with distribution ( no spark).
If you have experience in servicing your car you should start from checking if there is spark, and if petrol is being pumped regularly.
Best thing to do is always having it checked by a mechanic.
