2005 touareg water in oil not head gasket; getting coollant error n=messages - fill it, only to get messages again about 4km later with coolant gone

possibly the head gasket or a cracked block/ new motor try to take care when removing head so u can look at the gasket for damage

depends on the cost, oil seal if you can replace it ,it will sort your problem .but you have a158000miles on cooler already .if cooler is not too expensive i would change it completely

Can not be water pump, because that has a vent hole to the outside, and does not at all allow access to crankcase or cylinders. Oil cooler is also unlikely because oil is under more pressure than the water, and it would not get into the cylinder.
Water in the cylinder means up high.
That means head gasket or cracked head.
You can tell with a leak down test.
You borrow the gauge from a place like Autozone, and replace the water reservoir cap with it. Over pump it, about 30 psi. And watch for leaks. If same cylinder keeps filling, then you know where the bad gasket or head crack is. Diesels often crack heads. Not hard to do, but new head is not cheap. Probably $500 for part, $400 labor.

Cracked head or bad headgasket

Leaking head gasket. If a V6, replace both head gaskets.
Oil is seeping past gasket and getting into the coolant port holes.

There is a few things that could course your car to be over heating

• Air In Cooling System
• Coolant Leak
• Water Pump Failure
• Head Gasket Failure

These are some of the common problems as your car is reasonable new i would't think the head gasket has gone it is more then likely what you say that the water pump is broke probably the impaler has broken off. To bleed the system you need to get it up to running temperature and remove the bleed screws in the cooling system starting from the highest one working down then back up. If you find it is hard to bleed and no coolant is being pushed out it is more then likely that the water pump has gone. To test if the head gasket has gone take off the oil cap and look for a mayo type gunk around it if there is then this means that water is getting into the oil system meaning the head gasket has gone another test is to use a spacial liquid that test for exhaust gases in the coolant system.

u have a blown head gasket here and a cylinder that is full of coolant, this locks the engine up.

Yes you could have a faulty oil cooler.But The oil in the coolent has nothing to do with the camshaft.There just trying to make a fast buck from you.Tell them just to change the oil cooler and nothing else.

hello your intake gasket is most likely leaking internally into your engine.pretty common problem.the plastic and silicon gaskets get weak over time.

I hate to tell you this but its possible...

You have a leak. Look around on the driveway and try to determine if you have an external leak as opposed to an internal leak. If you see no coolant on the ground, suspect a blown head gasket. Do not continue to drive this car in this condition. If it does indeed have a blown head gasket, serious engine damage will occur.

Check your exhaust for white smoke. Chances are good you have a blown head gasket and coolant is leaking into the engines combustion chambers and is essentially burning off. Also check your oil, if it looks like caf mocha, this will confirm coolant is leaking into the oil via the blown head gasket
