Sounds like failed valve body the only fix is to replace entire valve body not a one part replace. valve body is in transmission on bottom of just inside of pan.

Your vehicle is in the limp home mode due to the transmission fault code. The computer will not allow it to shift. You need to take it to a shop unless you have experince with auto transmissions

Hi, vw experts, my engine light diagnosis was "turbo charger overboost" what might this mean? also, glow plug #4 cylinder circuit open. would this mean a faulty glow plug or faulty harness?...


First problem: "turbo charger overboost"
In your case the turbocharger is responsible for engine losing power.
The car goes in the "limp home" mode!!!
After scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this: Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECU (engine control unit) go in "limp mode" = engine protection software. As a result the "limp home" mode engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECU memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.


Second problem: "glow plug #4 cylinder circuit open"
Swap another glow plug in good condition by another cylinder, and see if the fault still occurs. If not, then this mean a faulty glow plug. If yes, then there is a bad harness.


Please do rate my response. Thanks!

P0440 code- EVAP control system malfunction any suggestions of what to replace to fix the code problem.


This should be an easy fix. It's the component that stores all the gas tank fumes in a carbon canister and after the car is started a solenoid controlled purge regulator cuts in and lets the gas fumes get sucked/burned in the intake.

On the top-back side of the throttle body there is a black hose around 1/4" diameter. Follow that guy over toward the passengers side of the engine bay and it should hook into a donut shaped piece just behind the air filter box (this is the solenoid-purge regulator valve).

Chances are this valve is stuck open or not coming on. When the car is warmed up and running if you touch this valve with your fingers you should feel it buzzing. If it is then it's working properly.

If this valve gets unplugged for some reason or is faulty then you will get the P0440 code.

With the sensor unplugged you can measure the resistance between its contacts. The valve should have some finite resistance and not open circuit. If it is open circuited or not buzzing then replace this valve. It shouldn't cost too much... under $20?

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.
