Question about 2005 Volkswagen Touareg

I got a "Check Coolant" error message from my 2005

    Ok...I just checked my coolant and it's brown. I read my manual and it says that the coolant will turn brown if mixed with the wrong type of coolant. When my coolant light initially came on I puchased universal coolant and poured some in. Could I possibly just need to have my coolant system flushed? If oil were in my coolant, would it be black vs. a thick light brown? Is the dealership trying to work me?

It could be just a worn out seal or a worn out/deformed cooler. In the end the only way to know what needs to be replaced is to dismantle it and check the status of the cooler. If the cooler is OK then just put a new gasket.

    Yes, if you mix coolants they will react and the colour will change - this is why if you need to top it off you either use the exact same one or replace it whole. It turns a deep brown when the coolant is really dirty - it's way past its 2 year replacement time. If oil would get in it it would turn milky and it would leave an oily film if poured on a piece of carton - you can try that yourself.

Losing coolant


take it to a radiator shop and have the system pressure tested
if the pressure remains static at pressure start the engine and see if the pressure drops
if it does indicates a water pump seal when running
check the drain hole under the pump housing for stains and water marks
something the garage should have done

Volkswagen touareg burning oil


Why would you think that?

No vehicle uses much oil at all--for over four months
& several thousand miles between oil changes

You have potentially serious oil consumption issues
or leaks

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


water doesn't just evaporate it has to be leaking out somewhere, how do you know that the head gasket isn't blown ? it may be cracked or the engine block may be cracked or a seal is leaking,water doesn't disappear it has to be going somewhere, it might be a good idea to have the radiator pressure tested to find out just where the water is leaking from .....hope this helps.....cheers.

My 2005 C240 has ticking sound in motor, engine light has been coming on, spewing white smoke, & chew up gas - just under 158,000 miles - time for new motor?


:sewing machine" sounds are usually caused by low oil. It may be that you are using too light a viscosity oil. Try using a heavier oil. The white smoke is troublesome. This is usually cause by burning coolant! If in fact the smoke is blue you are burning oil,and this makes more sense. The valvce stem seals may be worn out. These squeegy oil from the valce stems to keep it out of the cylinder head. If they are worn the oil is allowed to enter the cylinder head and is burned, causing the oil level to drop, and results in the "ticking" noises. It also uses more gas becasue oil doesn't burn at the tempterature that gas does and slows the cumbustion rate requiring more gas to maintian RPM's.Hope this helps.
