Hi ,
I am new to Audi, just purchased a daily driver 1998 A4 1.8T Quatro. Automatic.

1. Idle speed is around 850 rpm, is it too high? if so, how do i adjust.
2. I can't seem to find DIY for oil change, please point to right direction.
3. Car has 160k miles, what pm are necessary. Notice INSP light flashing.

Thanks.

 

1. 750 is normal. if it were me i wouldnt worry bout it unless it was at or above 1000
2. unscrew oil fill cap. take out drain plug (its on the side of the oil pan). drain oil into container. once fully drained remove filter while trying to avoid hot oil dripping down your arm. replace with new filter using some used oil to lube the filter gasket. replace drain plug. fill with 4.3 quarts of your choice of oil, usually use 0w-40 mobil 1 and a 301 mobil filter or ph3569 fram filter. replace oil filler cap. drink beer
3. if it breaks, fix it. other than that sounds like you should be on your second timing belt change fairly soon

 

no 850 RPMs is the factory set idle.

never use a tiny little crap fram filter. mobil1 M301 or the OEM MANN filters, or other over sized filters, only.

INSP light doesnt mean anything specifically.

 

ph3569 isnt the tiny little fram filter. its the same size as a 301

 

oh well that should be fine then. i dont remember what number it was but the last time i looked at a fram or purolator or K&N oil filter that said it fit the 1.8 they were all very small.

 

My 1600cc idles at 900rpm flat. So does my friends 1.8 NA.

 

Thanks for the inputs guys.
I found some diy for the timing belt, should I attepmt? Seems complicated. How much $$$ do I save doing it.

 

well if you had questions on how to change your oil, i wouldnt suggest getting into your timing belt change on your own.. my mechanic is a VW/Audi specialist and he said a timing belt job on a 1.8t for him to do with parts and labor would be between 5-6 hundred.. alot less than what a stealership is gunna run you for sure, but the only way i would DIY if i were you is if i had someone there with you who knows about these cars and has worked on them before..

 

yea if you cant figure out an oil change without a DIY, you should not be messing with your timing belt. if you screw that job up it can cost you several thousand $$ to fix. however you will save a few hundred $$ by doing it yourself. the timing belt kit costs around $300 for parts, and a mechanic is going to charge you $500-$900 for installation labor.
