2001 Volkswagen Golf Questions & Answers
2004 VW Golf, smelling fumes. The fumes come from
I emphasize with you on this problem. If you are smelling fumes you are inhaling car "exhaust" which is extremely dangerous as you know. I have a 1999 Passat that had a "fume" issue that baffled me for over a year. Your description of the conditions that you smell the fumes may not be complete enough for me to definitively say what your problem is but I will tell you what I experienced and discovered on my car. I only smelled the fumes when my heat or AC was on and the car was NOT moving forward. Also, if the AC recirculate button was on I didn't smell the problem as bad. So, what I found was that the car's emission control piping was leaking the exhaust fumes that bypass the pistons and go into the crankcase. These fumes are normally piped back into the intake manifold to be re-burned to reduce emissions. With a completed disintegrated rubber emissions pipe coming off the engine block, the fumes entered into the engine compartment which is sealed from the interior of the car. So, how did the fumes get in my car? Well, when waiting at a red light and with the heat or AC on (no recirculate) the fumes would fill the engine compartment and overflow out the wheel wells and wrap over the hood to the intake vents (near the wiper blades) of the car's interior air system. If the recirculate button is pressed with the AC on, the car's interior air (no exterior air) is recirculated inside the car to cool it faster and I didn't smell the fumes as bad. Also on windy days the fumes didn't get a chance to wrap over the hood and get into the intake vents. Because of the unique conditions that had to occur in order to smell or not smell the fumes it was a difficult problem to solve. By the way, the disintegrated rubber pipe was almost impossible to see and there is no real reference material to read that describes the location and depiction of the emissions plumbing. I hope this helps you!
How do I reset my
You probably need to do a throttle body relearn procedure. I'm pretty sure that requires a scan tools
The turbo on my golf 1.9 tdi does not kick in on 4th gear
One of the thin vacuum pipes must be torn and the minute you go into higher/full boost the ECU doesn't get the requested pressure from the turbo and to protect the tubo from overboosting it puts the car into limp mode, The limp mode only resets when you switch the car off and back on again.
Trace all the thin 6mm vacuum pipes and you will find your leak.
Hi I have a Golf MK4 1.6 16v S and have noticed
"smoke"?? you sure it's smoke & not water vapour/condensation?
the gunk in the oil cap tells you nothing really, you can check the coolant reservoir for contamination.
so, to sum up, i don't think you have a problem.
All the dash display lights suddenly went out
Modern CAN-bus electronics can do some very strange things when the battery voltage is very low and your description of events matches almost exactly with those experienced by a friend shortly before he needed to replace his car battery.
My own experience tells me some stereos should not be fitted to some cars or a discharged battery will result (unless the wiring is suitably modified). It is important to read the instructions - carefully!
I strongly suggest you have your battery and charging system tested and the stereo removed until it is discovered to be compatible...
