WHAT TYPE OIL USE A4 2,5 TDI

When have you checked the oil level recently? Short beeps/chimes indicate a low oil condition. If you are just a bit low it could be that it comes on when more oil is in the engine and less in the oil pan. (the chime is set off by the oil pump pressure sensor). It could be sensing it is dry/low pressure. If you are in the US what kind of oil are you using on your TDI. No insult intended but unless the dealer is changing your oil, or you are.. most oil change shops figure foreign car = castrol 20w50 oil! That is SO wrong for your TDI. 1. Check your oil regularly.. A diesel will burn oil more than a standard gasoline engine. 2. Change oil regularly.. where regularly is dependent on the type of oil being used. If you are using STANDARD "dinosaur" oil then you should keep to intervals of no more than 5K miles between changes. If you are using SYNTHETIC 100% then you can extend the change intervals up to 10K miles depending on quality of oil and driving habits. NOTE Check adn Change are two diffferent things. You should check oil everytime you get gas, make it a habit. As for the proper oil. You require VW 505 which is a European standard.. the US equivalent code is a C rated oil for COMPRESSION ignition engines.. meaning DIESELS. Look on back of oil bottle and make sure its rated C-H, C-F, or C-I to meet your requirements. I run a TDI myself and use Mobil 1 Synthetic Turbo Truck and Diesel motor Oil with a WIX filter. For more tips and tricks on your TDI I suggest a website called www.tdiclub.com its amazing the knowledge on that site that is purely for the TDI motors.

not really. The TDI's have a drop in filter, and you will only be loosening the cover that the filter rests in. It should be hand tightened from the dealership, so a simple oil filter wrench will work. rubber gloves can sometimes disengage it also.

The best oil for A4 2000, 1.9 TDI, 85 kW, is CASTROL 0W30 SLX Longlife II (TDI Pump Nozzle) VW Norm 506.01 . This oil is issued by Castrol special for TDI - Pumpe Duse (Pump Nozzle) engine as longlife oil (50,000 km service interval, or two years).
Also a normal service oil (15,000 kmservice interval, or one year) is Castrol TXT 5W40, and Castrol EDGE 5W30, for TDI Pump Nozzle engines, VW Norm 505.01.

new synthetic oils have lost a chemical in past couple of years to save on $ I use a brand called ams oil 5w30 along with a lucus oil additive and a hastings oil filter. have over 218000 hard miles and still going. proof is in the pudding.

on the bottom of the oil cap stick there are 2 places it seems possible to put the o-ring. If you are holding the cap as it would sit installed, with cap on top and stick hanging down the o-ring goes on the bottom groove, the thicker of the two

There's a few that you can use - but in general

Use Full Synthetic only for the TDIs...

There's various schools of thought after that in terms of 5x 30, 5w 40, even 0w 30 or 0w40

I've been using Castrol Synthetic 5w 30. The original specs for my 2000 Jetta TDI may have been for 5w40 oil formulated for diesels - but with the Synthetics now I think the 5w30 is felt to be the best in terms of what works best in the Turbo

You can probably go every 5,000 to 7,500 miles between changes - a good thing since the synthetic oils are more expensive

by the way, some also suggest changing the fuel filter at every oil change. I'm thinking that's a bit much but others may disagree... maybe ever 15,000 miles for me

I looked it up, add 4.5 quarts oil and filter

The oil filter is in a filter housing located on the top of the engine. Take the engine cover off. The 3, 10mm nuts are located under the circular pop-off covers that attach the plastic engine cover. You should see the oil filter housing to the right of the engine valve cover. The oil filter housing is a black, plastic cylinder with a cover that unscrews. The filter is inside of this. Make sure you drain the oil before unscrewing the cover to the filter housing.

PLASTIC HOUSING ON LOWER FRONT OF ENGINE

It is on the passenger side right behind the washer fluid fill tube. You can follow the fuel lines (look like 1/4" black tubes, some are clear) from the injector pump to it. It is a caniser a bit bigger than a normal looking oil filter and sits between the washer bottle and the metal that forms the wheel well. It is held in by a screw type clamp about half way down the cylinder. Probably isn't the fuel filter unless there is air in the lines to the injector pump or they didn't bother to fill the fuel filter up with diesel after putting it in. There is not a fuel pump in the tank in these cars so everything is sucked up by the injector pump and it needs to be primed properly.
