#923 of 2367 Coolant temperature sensor or not?
Sep 03, 2005 (6:58 am)
I had an orange warning light up on the dash of my 2000/2001 1.8 A4 and nowhere in the handbook is it mentioned. Fortunately my neighbour is a mechanic and told me it is supposed to illustrate the shape of an engine and it is the engine management system reporting a problem somewhere. Unlike on Volvos where it is possible for anyone to interrogate their system and identify faults from a chart, it requires a laptop with Audi software to be connected to the A4 by an expensive service engineer to read the report and then the same action again to reset the light after any repair work is done.
Apparently the 'coolant temperature sensor' costing £27 Sterling had a fault but was now showing as working OK and the light reset. It may have just been a loose plug on the switch but nevertheless I am having the sensor changed because at £75 for the fault diagnosis I cannot afford for it to keep happening.
Much more of this contrived robbery and the A4 will go!

I had this problem about a year or so ago and actually got some help from other folks at this forum. If you are using the AC and the auto mode, it will put cool air out all over the place and the windshield will keep fogging up. The advice I got and now use is to use only the middle set of vents (selected on the right side of the control panel) to blow the cold air only through the dash vents towards you. If you don't select a set of vents the air goes out all three areas (dash, floor and windshield) and that cool air blowing on the windshield is what is causing the fogging. I drive with the temp at LO 99% of the time and when it is hot and humid out (particularly at night) the only way to keep my windshield clear is to keep the air coming out only from the dash vents. I was surprised by this, but it works. Good luck.
#925 of 2367 Additionally Oil Change?
Sep 04, 2005 (9:55 pm)
Hi everybody, I know this has been a question being asked many times. But after searched and looked for the related msgs still can't find a certain answer.
I got a 2005+ Audi A4 manual. I really wanna keep it in good condition. And from the previous Msgs someone said that did an interim change with Audi approved Mobile01 oil (change by using oil extractor ourselfves) will get a good result. Does anyone do that and have a good result without violating the service agreement?
and how to avoid the sludge problem? is it related to the gas you pump or any driving habit??
Thank you very much
#926 of 2367 Pella Oil Extractor - works great
Sep 05, 2005 (4:44 am)
I do change my '04 at the mid-point of the Audi recommended 10,000 mile intervals. I use that oil extractor and leave the dealer installed filter. I have see this recommended by others and I have done it twice so far. I use Mobil 1 0W-40 (European spec oil) as it meets the Audi required specifications.
The process is very simple and clean and I get out about 3.5 quarts of the oil using this method.

That's pretty much what I've been doing with my A4s... oil change with synthetic every 5k or 6 months, whichever comes first. However I haven't used an oil extractor (better pick one up, eh?).
You know, what people seem to not note is that while Audi says to change the oil every 10k, they mention that the interval should be more frequent if the car is driven short distances, in freezing weather, or dusty environments. Imagine that .

Hi..Thank you for both of the reply above.
so do I have to buy the European spec oil of Mobile01? what's the difference if it is not European spec??
And now I'm just in my break in period.. and the first oil change will be 5000mile. Do I have to change oil myself before 5000mile??(like at 2000 OR 3000 miles)
besides, you said that you change 3.5quarts yourself. but isn't that the total oil changed will be like around 6.5 quarts? so you just change part of it? is there any reasons?
sorry for my stupid question.. Thanks again for the answer

The Mobil 1 oil is one of the few that meets the Audi specifications. The exact information is in the owners manual, but these engines require a very specific type of oil and this is one of them.
Changing the oil this way gets 'most' of the oil out and about 1 quart is left if you have a 1.8T engine. The 6 takes more, that detail is also in the manual.
An early change should not be needed at all as the initial 5,000 should be fine.

Since you have a manual 05+, I'm pretty sure that you have the 2.0t engine. While I can't recall exactly what the manual said about oil capacity, I believe that it is around 4.5 quarts.
As JR mentioned above the 5 k interval should be fine. On my previous A4 my first change was at 5 k and the car never ever needed any oil between changes... this suggests that the engine had healthy piston rings. But a big part of that is driving smoothly, avoiding WOT, high rpms, varying rpms during that critical 1000 k break in period. I also gradually (and gently) let the rpms occasionally move further up the rpm band.
#931 of 2367 Re: Oil change and timing belt [ndlessfun]
Sep 06, 2005 (9:42 pm)
Ok, these posts about timing belts are truly scary. I have a 2001 A4 2.8 quattro w/ 97k miles. I was told, by both the audi dealer and a local mechanic that I trust, that the timing belt for an 01 2.8 quattro should be replaced at 105,000 miles. Has anyone with a 2.8 had a problem with a timing belt failing before 105k miles? All of the posts about failing belts involve 1.8 Ts. Needless to say, I intend to have my timing belt replaced as soon as I can (within the month) but wondered, if it fails before I can get it fixed and there is engine damage do I have any recourse considering I was advised that it should not be a problem until 105k miles?

What's the ski sack on the 2005.5 Audi's that's included in the Cold Weather Pacakge? Is this something visible?
