Question about 2000 Audi A6

1 Answer

So my Audi A6 2.7T was going well after I bled the cooling system. I drove for 1000kms without any problems. Then I noticed that when you stop the car, switch off the ignition, wait a minute and turn the ignition on the temp gauge rises from 90 degrees to 100 degrees. I start the car and the temperature drops. Is this normal? The second issue is that in the mornings only, while I am driving the temperature reading fluctuates between 70 degrees and 90 degrees. Is this normal? My heater also comes on when it feels like it, then the car overheats. No this is not normal... Please Help. Tx

    I also noticed thatin the mornings the car starts hard (3rd swing) and has a slight splutter. What is the cause of that?

    In the mornings the Audi starts hard (3rd swing) with a slight splutter. Can this also be a part of the same overheating problem?

Hi! It's not normal definitely. This things are cause by a coolant leak somewhere. You will have to observe the hose if there are mists coming out. A tiny hole can cause a lot of stress on the engine and will definitely overheat. We are facing some coolant leakage and worn hose problem that definitely needs replacement. Hope this helps and have a good one!

    I have had it pressure tested, and they cannot pick up any leaks. I am thinking of a radiator/cooling system specialist to clean and flush out the system as well. Will that help?

    Yes you may try that.... The radiator could be clogged causing the fluid to circulate slowly which may cause heating too.

The best test for this is a cooling system pressure test. You need to have that done. The other thing to check are the freeze plugs.

Sounds as if the electric fan on the radiator isn't coming on. Most radiator shops also work with A/C systems and may be more qualified to do the work. However, any good "normal" repair shop should also be able to diagnose the problem. Try not to drive it very far and keep close watch on the engine temperature. An overheat can do extensive (expensive) engine damage. If you have a fill cap on the radiator, fill it there (when cooled down) filling the recovery bottle may not be sufficient to get coolant into the engine.

Sounds like low automatic transmission fluid. Have you checked the fluid level. Have you noticed it leaving spots where it's parked?
We used to have an Audi A4 wagon and the transmission was always reliable for us. We always kept it well serviced. Audi's (like all high performance cars) need very regular service and attention to be kept going well.

My car keeps running hot. I am having to add fluid often. I do add antifreeze. There does not seem to be a leak. Do you think it might be the water pump or the cooling fan? I drove 50 miles today with...


By your description, there would be no way you get 50 miles without a rad fan working or water pump problem, when you said you've put the heat in and the cars temp went up that means you have an air bubble in the system which was not properly bled.

1996 audi a4 aircon problem


You have a leak most likely, and these are typically hard to spot without test equipment. Take it back to your technician and ask him to recharge the system and perform a dye test to locate the leak. Could be as simple as a bad o-ring in a fitting, or as complicated as a seal in the compressor.

My 2002 BMW 330i is still running hot have not checked the head gasket, but could it be a gasket problem if the oil is clean and there is not smoke from rear? They bled the coolant system; they drove it...


Do you have oil in the coolant tank? Is your coolant greyish in color? If so then your headgasket is in deed blown. If you do not see a leak, and you are sure that the air is bled out, then the engine is burning your coolant and it is going out the exhaust. When bleeding the cooling system it helps to raise the front end of the car higher than the back end, any air in the system will make it overheat. Hope this helps, let me know

Brakes locking up


Similar problem on a Toyota truck. Turned out to be a combination of items.

Bad valve in the master cylinder.

Contaminated brake fluid.

Basically the heat in the rotors was boiling the brake fluid cause it to expand and lock up the brakes.

Not sure if the fluid contamination was caused by the master cylinder or the other way around. (it is the whole chicken or the egg argument.

My recommendation is start at the right rear wheel. Drain the fluid until it is at the bottom of the reservoir. refill with new fluid. Bleed the entire system. working your way around the truck from longest run to shortest. (Distance from master to the wheel)

Take your time and don't rush the job. After you have flushed and bled the system, go for a check ride. If the condition continues, you likely have the defective seal in the master cylinder.

Good luck, let me know if you need any other info.
