Volkswagen golf mk4 1.4 16v engine - danger of freezing in cold weather

Hi, I recently got a "new" (well, built about September 2001, model year 2002) VW Golf mk4 1.4 16v with AXP engine and have now learned that due to some construction errors there is a significant danger of engine damage in seriously cold weather (say, about -8 degrees C or below). The cause seems to be condensed water in the oil separator which is freezing and blocking the oil circuit until the oil gets ejected via the oil gauge tube, in the worst case leaving the engine to run dry. The tube leading to the oil separator already has been upgraded with a heating element provided by Volkswagen as "level one solution", but this does not seem to be enough (there are several reports of engine failures due to freezing despite the heating element which seems to not be situated in a perfect position - heating only the tube and not the separator itself which can freeze as well). VW offers another upgrade with "PCV" (part no. 036 198 999 D), however according to one of their mechanics, it is not compatible with my engine (air filter), although the motor identification code indicates compatibility. Is there anything else I can do? I intend to schedule the annual technical service intervals to the beginning of winter in order to have the oil changed (and thus hopefully condensed water removed). However I do not own a garage, have to drive short distances frequently (meaning more condensed water) and it does get below -10 degrees C in winter here quite often, especially at night which seems to me to make starting the engine early in the morning quite a risk. Any help would be greatly appreciated. Thanks in advance!

SOURCE: 2002 volkswagen golf gti has a leak in the passerger foot well

hi from uk a common problem with leaks into foot wells are as rain runs down w/screen and inti the bulkhead area below w/screen accesable with bonnet open ? this water runs to either side to a drain hole and onto road via a rubber hose attached to these drains the bottom of hoses are flat so as to let water flow out but not inwards ok so far ?? now leaves and dust etc are sometimes carried to these drains resulting in eventual clogging at bottom and top of hoses so water collects in pools eventually finding its way into car ? take a look at these and ensure hoses are clear ??

SOURCE: vw golf 2001. coolant system not working

Your most probable cause for this is because your water valve needs replacement or repairing. Not all cars have a water valve that brings the heated coolant into the heater core unit.

Essentially, the heated coolant is brought from the engine block directly, into a mini radiator that has a fan to blow heated air into your vehicles cabin.

If that valve were clogged, or the switch itself to open up the water valve that blocks the coolant from going into the heater core unit, then you wont be able to get heat from the vents.

ALSO, another reason why your car might also be overheating as well, is you need to check your coolant levels as well to make sure it is fully filled up, if it is, then your thermostat might also need replacement.

good luck with your problem.

Based on what you are saying I think the fuel pump would be suspect, these pumps stick and cause a no start in cold weather.

I bought volkswagen golf 2 year 1987 i cant identifty the cars model weather its gli gti or some thing and the car is now consuming a lot of fuel the local mechanic told me that the couse for the fuel...

It the temperature sensor is faulty the ECM will think that the engine is constantly cold so it will keep the fuel to air ratio high constantly = the fuel consumption will be high. Your mechanic is probably right, and replacing the sensor is a relatively cheap job - less than 50€.
BTW to identify your exact model just look on it's ID badge, it's inside the engine bay .

Hi, engine on my golf is starting always on the second time? what can be the problem? thanks

this is not uncommon in any car, it just means that the car is getting older. it can be fixed by replacing the battery (if battery is old) or by reconditioning the starter, although it would not seem to be the proplem on such a new car

Smoke when cold weather or when accelerating

i would not worry too much about it as diesel cars do let out black sulphur when accelerating it might need a good run at a faster speed to clear it out if it is driven around town a lot at lower speeds
