The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

    Thank you for your advice. I got my Golf4 diagnosed and the problem was with my Coolant Sensor which did not give a good response with regards to the temperature. It has been fixed and the next step is to get the O2 Sensor changed. Any idea of how much it can cost?

    Clear the O2 code and drive it for awhile, the sensor was just indcating it was seeing a problem with fuel control/mixture, that is likely a resault of the coolant temp sensor problem.

  • ARTHE Damien Oct 30, 2012

    Thank you for the precious advice. Actually the car is running very good. If i understood you, the O2 sensor does not be changed right now.?

There is a part between the air intake manifold and the air box on your engine, it's usually black on a golf, will look like a 15cm tube around 80-90mm in diameter with a plugged wire leading into it, this is your MAF sensor or MASS AIR FLOW sensor and if dirty / faulty can cause an incorrect temp reading from the air intake and cause rough engine starting, this is a very common problem on mk4 golfs... the part is apparently cleanable, with isoprop alcohol, or I assume white spirit. the actual sensor needs to be removed from its housing for cleaning, and as always treat carefully... the part replacement, depending on where you go can be around $50 - $100 used or even new.... part number off the existing one on your car, try ebay as you can do well for price :) could be fouled spark plugs from rich fuel mix on bad airtemp sensor, could be a million things but the MAF sensor is one of the golden oldies I'd be checking first :) Goodluck, Chas

Where can you find the radiator cap in a volkswagon bora v5


Janet, top up your coolant in the coolant reservoir/expansion tank it is the rounded bottle closer to the shock tower.. Remove Blue or Black cap when engine cold and top up, run engine till warm and recheck after cool and top up again if necessary. Make sure to have leak repaired sooner then later to prevent future costly repair.
Check the attached links,instruction and guides, Good luck

What could be the cause of rough idle, smoke, engine cut off while driving in my vw golf mk4. All of a sudden it happened. I replaced the spark plugs, filter elements, and cleaned the throttle, to no...


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.

I'm having rough idle and smoke all of a sudden with my golf mk4 The oil warning lights up in dash. Oil level ok. Spark plugs not burning well. Replace spark plugs, changed oil filter, changed


Smoke is not a good sign. Running rough is not a good sign. Oil light not a good sign. You could have a combination of bad things, most likely expensive. Suggest professional help. Smoke can be bad rings or holed piston. Low oil pressure can be bad bearing or oil pump.

VW Golf Mk4 1.4 16v Oil Light Warning on Dash


Measure your oil at normal operating temp, without the engine running of course. This will give you a more accurate reading once the oil has circulated in the system.

The system works like this:
  • With the ignition on, the oil pressure indicator light on the dash should come on and flash. Once the engine is started, the light should go out and stay out as long as the engine is running.
  • If the oil pressure drops below approximately 0.3 bar or 5 psi when the engine is running below 2000 rpm, the light will flash.
  • If the oil pressure drops below approximately 1.8 bar or 27 psi when the engine is running above 2000 rpm for more than 3 seconds, the indicator light will flash and the buzzer will sound.
If either this two warnings occur:
  • The engine should be switched off immediately and the oil level should be checked.
