2002-vw-passatMy brother accidentally put steering fluid into the the part where the transmission fluids go. What do you suggest that he does?


Transmission Fluid Contamination

It would depend on how much and if the vehicle has been operated or not since this was done. If just a tiny amount of power steering fluid was added I wouldn’t worry to much about it. A tiny amount would be less than a 1/4 of a quart. The two fluids are not the same but that small of an amount shouldn’t make a difference. The automatic transmission holds only 3.2 quarts of fluid in it for this vehicle.

Now if 2 or 3 quarts of fluid where added and the vehicle was driven, then you may need to drain the system.

Automatic transmission fluids

Automatic transmission fluids can be broken down into two types, Dexron® III and Ford type F. These fluids are specific to the transmission using them. Don’t assume that all Ford vehicles use type F, they don’t!

  • Dexron® III, sometime referred to as multi-purpose ATF. This replaces the old Type A, Suffix A, was recommended by GM, Chrysler and AMC between 1956-1967. It also supercedes Dexron® and Dexron® II fluids. Ford vehicles 1977 and later with the C6 transmission or the Jatco transmission in the Granada and Monarch also use this fluid. Ford refers to this fluid as Mercon® , or transmissions where type H or CJ where recommended.
  • Type F fluid is recommended by Ford Motor Co. for most late model Fords and certain imports, and contains certain frictional compounds required for proper operation in these transmissions.

There is not much of a problem here, since the bottles are clearly marked to indicate the type of fluid. If you are in doubt, check your owner’s manual.

2007 VW TransporterMy T5 keeps over heating and blowing the coolant out of the header tank. When it overheats the fans in the car just blow cold air out even on the hottest temperature. When driving along there is some heat out the fans then it will get cold for a minute then get hot again. I had the head gasket done less than 12 months ago. Recently I have had a new coolant temp sensor, new thermostat and it has been in to the VW garage for the past week who cannot identify what the problem is! They have said it is maybe a blockage but not come up with where! Any help greatly appreciated.


From what you described it sounds like the coolant level is low or has air in the system. Of course if there is a leak internally or externally you will want to repair it right away. Keeping note as to how often the coolant level goes down is a good indicator of how big the leak is.

I have outlined some helpful diagnostics for an engine overheating situation.

2006 VW PoloRandom Loss of Throttle from Pedal

My car loses power while I have the gas pedal down . What happens is the engine will start to decelerate as though I’ve taken my foot off the gas but my foot hasn’t moved off of the accelerator. Then I have to release and step on it again to regain speed. VW Polo 2006 model 1.4. I have changed the petrol pump,did the service on the car and even changed the Accelerator pedal My car is a manual transmission. Lately I noticed that the breather hose has a small cut on the small soft pipe that joins the thick one and it has a little bit of oil spill on it. Can that be a problem, we did a diagnostic and there’s no error code on the car.


Yes that can be a big part of your problem. Any leak in the hose will cause an issue.

2011 VW JettaThis car is on the National emissions recall list. The other day, check engine light came on and I took it into VW dealer…ran a diagnostic and said I need a new Catalytic Converter. Can this be attributed to re-call for emissions ?


Yes it could, but not likely. A catalytic converter works or it doesn’t. The rear O2 Sensor reads the air/fuel burn and determines if the converter is doing its job or not. When it is not a check engine light is illuminated and the PCM stores a p0420 code.

Now since the VW manufacturer has cheated the electronics on the vehicle with programming it makes it possible. They could have changed the programming to reflect a different set of parameters to signal a converter failure. That being said, the manufacturer would have set the parameters in favor of the converter working better, not worse.

If YOUR vehicle has already undergone the recall reprogramming and repairs then NO. the Converter would not have anything else to do with it. Arguably, the converter would wear out earlier than expected due to more fuel being allowed to be burned throughout its life but I don’t think the courts are going to re-open the case.

If the vehicle has less than 100,000 miles on it the catalytic converter should be covered under manufacturer warranty. If it is over 100, 000 miles then it would not. As far as the re-call for emissions it depends on the recall notice for your specific year vehicle.

You can drive the car with a bad converter forever without any issue. The check engine light will stay on but no drivability issue will occur. The converter is required for emissions and only help air quality. It does not effect the vehicles ability to perform or not.

The good news is you can sell your car back to the VW dealer and receive a cash bonus on top of your trade in value. Or if you wish to keep it, repairs will be made to your vehicle. This is your choice as you can not get both.

VW Emissions Recall Settlement

As a result people who want to keep their cars, there will be a recall to bring the existing models up to regulations. The fix will likely be a software update for newer models. Pre-2015 cars are expected to need additional components installed—which may mean it takes longer to develop and deploy the solution.

2010 VW CCI keep getting a code to “replace Crankcase Regulating Valve, but when I look for info on it I keep finding PCV valve. Is this the same thing? or a different part


Same function. Same part. Different name. Same thing. IT is a crankcase PRESSURE regulating valve. This allows the crankcase to vent pressure so it runs smoother. PCV  stands for positive crankcase ventilation.

A faulty PCV valve will allow pressurized intake air back into the valve cover/crankcase. This pressurized air can blow out several openings. The oil filler cap, air filter and dipstick should be checked for evidence of oil blow out.

Crankcase Regulating Valve/ PCV Testing

  • With the engine OFF, remove the engine cover and locate the hose connecting the intake manifold to the crankcase. Disconnect the hose from the intake manifold side and clean off any residue with a cloth. Blow into the hose and if there is some resistance then the check valve is operating correctly. If there is no resistance, then the PCV valve should be replaced.
  • In addition, with the engine running, disconnect the hose from the valve cover. Plug the hose and check idle quality. If the idle quality improves, replace the PCV valve.
  • Furthermore with the engine running, remove the dipstick. If the idle quality improves, replace the PCV valve.
  • Finally Remove the cap from the oil filler hole on the valve cover. Place a stiff piece of paper over the opening. The paper should be sucked against the hole and within a couple of seconds if the PCV is operating properly.

2005 VW GolfI noticed this in my 2005 Golf GTI 1.8t. I was wondering if this could cause weird rev spiking and shifting issues. It basically had no power steering fluid. I replaced the pressure switch and added fluid, and so far it seems to be fine.

But curious of how a power steering issue can affect the engines rpm’s and therefore shift points.


When the power steering fluid level is full, the engine has to labor in order to turn the pump that creates pressure. When the fluid level is empty, the engine does not have to labor as hard. Air is easier to move than fluid. I am guessing there was a small amount of fluid and when the pump would go empty the engine would rev and the little amount of fluid would return and cause the rpm to lower. I have not tested this, just my opinion.

Hi my name is Amod and I have a golf 4 gti 2lt with management system. My question is every time I park my vehicle on an incline or decline it refuses to start but when its parked on a flat surface it start on the turn. Why is that? please help with this question.thanks


When it won’t start you will need to determine what is missing from keeping it running.

  1. Spark
  2. Fuel
  3. Fuel Injector Pulse
  4. All of the above

Once you have found what is missing you will need to narrow down a cause.
