Hi all. My wife and I got our first Audi, and we love it (well, probably more me than her)! Anyways, I have all kinds of questions, but most important is my first oil change. It's an '04 A4 1.8T Quattro UltraSport. I've read a lot about the Mobil 1 filter and even the K&N filter, is either one better? Also, and this may be me being overly cautious, which one is the equivalent of the oversized stock filter (if you have part numbers, that would be awesome)? As far as oil, does anyone here run Amsoil? Otherwise, what are some of the better oils to run? I don't have any engine sludge as far as I can tell, and I want to pamper this thing.

Does anyone have any experience changing out the coolant temp sensor? I've changed mine out, along with the o-ring, and there is a small leak now. I'm going to get another o-ring and a new clip tomorrow, but I was wondering if anyone else had the same issue.

I look forward to learning as much as I can from you all... great site!!

 

Use factory filters or german equivilant like Mann or Mahle www.ecstuning.com
Oil should only be synthetic with a turbo charged engine, Amsoil is excellent, as is royal purple and redline. Mobil1 and castrol synthetic are not far behind.
As for the coolant leak, make sure its actually not leaking from the flange that the CTS sensor is sitting in. The plastic flange bolts to the head and has a large O-ring that commonly leaks.

 

You can get the oversized filters at advance auto parts locally. I have used Mobil1, Purolator and currently Fram on this oil change. If you stick with an oil that meets VW.502 specs you will be in good shape.

 

Thanks for the help! Now, are there any members in the Oklahoma City area with a VAG

 

Do you have a part number for the Fram or Purolator?
I wouldn't use either my parts man can cross ref the numbers of either one of those
to the Wix that I use. He only shows the small filter available for Wix. He is sure he can cross if he has something to go by.
Thanks

 

NEVER EVER put a FRAM on your CAR!!!!!!!!!!
FRAM filters and others like it DO NOT HAVE A BYPASS VALVE IN IT.
So if the filter were to ever get clogged your oil pressure would go down to zero, and if your oil pressure is at 0 while driving.............................BOOOOOOM goes your engine. Spend the extra money and buy the correct filter.

 

Yah I wouldn't get a fram either... Ever.... I use the Mann filters and I usually order several so I don't have to pay shipping more than once.. I found them pretty cheap on rockauto.com along with other parts.

 

Yep, i used to go to the Dealer and buy an OEM oversized filter for 1.8T.
Now i go to my mechanic for the oil changes and his ELF oil ))

 

What do you guys think of this oil?

 

Considering the life of a car is the oil changes, I have never skimped out on it and have always taken it to the dealer for full-synthetic. Apparently, they use a custom Castrol Syntec formula that is only found in affiliated dealers and specially made for the related cars. German cars can't take much alteration as American cars and require very precise handling. If you stick to what it asks to the point, these cars can last you a lifetime.
