Fuel filter may be clogged, replace. Fuel pump may be failing, replace. Never let your vehicle "run out of gas" as all the residue collected in the bottom of the gas tank, will migrate through the system and create problems.

I have an audi 97 a4 6 sylander and i had to change the metal pipe wich transfer water from reservor to termostat housing do i need to bleed the system after fix and soo wher is the bleeding valve thanks...


you dont have to bleed the water it automatically takes out the air when it runs and the thermostat valve opens check the level again after a run of 5 miles or when the temp is in the middle

remember not to check when the engine is hot

1997 a4 se overheating.i have changed the thermostat and car is still overheating.cold air is coming from the blower.car drives perfectly otherwise.fan is not coming on.how would i diagnose the problem


Alot of time you have to bleed the cooling system after changing a thermostat it gets an air pocket in it look for a bleeder valve near or on the thermastat housing if so bleed it to get the air out.check the radiator and make sure its full because if you filled it up after changing the thermastat once the thermastat opened after the engine ran awhile well the cooling system needs refilled.

How do i change front brake hose on my 98 audi a4? where is it located?


Its located on the brake caliper and goes up to the brake line,To change just remove the high pressure fitting from both ends [very basic job]Fit the new pipe ,but now you have a new pipe but full of air!.To bleed out the new pipe just open the bleed screw [looks like a grease nipple on the top of the brake caliper]and connect a small piece of hose [must be a tight fit on the bleed screw]with the bleed screw loose and the hose fitted just fit the other end in to a container of brakefluid and press the brake slowly up and down till all the bubbles are gone{dont forget to top up your reservoir before you bleed it!!]as if the reservoir runs dry you will need a special bleeder to bleed the brakes [it requires 2 bar or 30 psi pressure to bleed out the system after the reservoir goes dry]

Looking for procedure to properly bleed an audi A4 1.8T quattro cooling system as no sign of a proper bleed point on any of the heater/cooling hoses/pipework, car overheated today & blew out some...


You didn't say what year the car is or what other diagnostics you've done lately...My guess is the radiator core is plugged...If you want to tackle it yourself, buy a Chiltons repair manual at AutoZone or NAPA stores ($25). I suspect you'll have to order the manual.
Good Luck

1997 audi A4 heater blowing cold air


You probably have a leak in your oil cooler. This is causing the oil to bleed into your cooling system causing the "thick brown liquid". This in turn will also cause your engine to over-heat since the cooling system is contaminated.
