Audi a4 2lt TDI 2005 vacuum pump leaks a lot of diesel what is the cause of the problem


Sounds like you have an internal vacuum pump leaking. There are some videos that show how to repair, but the life expectancy is short. Recommend replacement.

I have a 2004 audi a8l. Its overheating but fluid is fine. And both fans are working. What do i do? What is it ?


The fluid level and condition may be fine, but it will only cool the engine if it is recirculating properly. Is your radiator blocked? Check thermostat is opening at the right temperature. Water pump etc.

Audi A6 2001 quattro 2.8 mysterious over heating


Yes, replace the thermostat. Then you need to 'burp the coolant system'. Your car has all the hallmarks of air in the system, especially a heater that is cold. This is because there is no water in the heater matrix. This is why it overheats. The system must be full and with no air to circulate correctly through the radiator.

Burping involves the following steps.

Remove the lid to the reservoir, remove the radiator cap, fill the radiator to the top, turn heating on full blast, start engine and get to operating temperature, keep topping up. Squeezing the radiator hoses helps. The level will rise and then drop when the thermostat opens. Top up when bubbles stop and the level becomes constant. Put radiator cap on, top up the reservoir and put the cap on that.

My car is altima 2005.it is heating when drove more thane 100 k/h.Please could help me?


Hello, have you done a maintenance on the cooling system, radiator flush, thermostat replacement, hoses, water pump etc? Also, has anyone taken off the radiator shroud? believe it or not, the shroud plays a big roll in the cooling of the engine.

If its not the cooling system

Is there any oil in the radiator fluid, or water in the oil, the oil will almost look like coffee creamer. check for white/blue smoke coming from the tail pipe, if you can do a pressure test in the cylinders, it may be the head gasket then.

My Audi A4 2000 TDI year 2005 has run on two tanks of Bio fuel recently and it hasn't recovered... started stuttering. Fuel system has been flushed out, air flow mand air flow meter has been changed but...


Audi 1.9 TDI and 2.0 TDI engines with pump-nozzle injection system, (year 2005 included), don't have permission to run with Bio fuel !!!
First you must replace fuel filter, interflow a quality Diesel additive (for 60 liters Diesel fuel dosage) fill up tank with Diesel fuel and run at least 300 km on highway at 3000-3500 rpm in 4-th gear.
I recommend you Foerch Diesel Reiniger System additive! I use this additive from 3 years ago and is certified on Audi TDI engines!

2005 kia spectra over heating


Did you install a new thermostat and make sure to bleed all the air out of the system when you replaced the radiator? If you didn't, or installed a Stant thermostat, replace it with a FACTORY OEM thermostat. Make sure the cooling system is bled by opening your radiator cap (WHILE THE CAR IS OFF AND COLD), starting the car and running the heater. Add coolant to the radiator as the engine heats up, until is at normal operating temperature AND starts spitting coolant back out.

Hope this helps,
matt

Complete cost to replace the water pump a8 2005?


Depends on where you go. A dealer is going to charge you through the nose. An independent shop will be somewhat less. I'd recommend you do the whole timing belt service though - the water pump's replacement schedule is along with the t-belt, tensioner, serpentine, etc.

If you're in the northeast US, reply here with an email address and we can talk. I do Audi servicing out of my own garage and can likely beat the indie shop's prices (and the dealer for sure) since I don't have the overhead of a shop:)

2003 Audi TT Quatro Coupe. The radiator cooling fan does not work. Vehicle over heats because the fan does not work. Replaced the radiator cooling fan motor and the temperature sensor. The problems is...


The main reason for the over heating of the audi tt is to do with the water pump. The propeller within the first type of water pumps is made of plastic. This was to prevent corrosion, however was never designed to last longer than 5 years. What you need to do is purchase the new style water pump. These new style water pumps have been designed with a metallic propellor which should resolve the overheating. Let us know how you get on.

Volkswagen jetta over heating


hi tammy
it could be an air lock stopping the water from circulating properly i seem to recall this problem on the older VW Derby and audi 50 (same engine) there is a small bleed screw at the highest point on the cooling system that allows you to bleed this air out youll find its location in the manual

another thing to try is put a flushing agent through the system incase there are any blockages in the radiator itself

hope this helps
