I hear there is alot of problems for euro cars after they reach about 100,000 miles. would you know what usually happens to A4 after they've reached about 100k miles? does the turbo just die? and/or is there more problems with the engine itself.
Thanks for your input.

 

generally you can get tons more miles outta that turbo before it blows. unless you've pushed it to the max like every day. lol

 

i just bought a 97 a4 1.8 and i have to rebuild the engine because one of the pistons fried and got metal shavings in the oilfilter and fucked it all up but i donno if thas normal or if the prev owner beat the hell out of it. but he says the turbo is still in good condition

 

a 1.8t is a very good engine of german engeneering. you should not push it when it´s cold and oil temperature is below 75° and drive it slowly on the last miles if you pushed it very hard over a longer time.
and you also should look some thimes after your.... ähm what´s the word... the thing that flows the air through bevore it comes to the engine and puts the worth to the engine management. indicators of a fault in this is less gas than you know it from your car and you have less power than normal.

when you thread it right and everything is ok it´s ready for 200k miles!

 

actaully that is normal with the 1.8. they are notoooooorious for oil sludging. im not sure if thats what caused your engine to fail but it is truely a big problem with the 1.8t. alot of people are very mad at audi/vw because typically they wont pay for the engine which many feel is a engineering defect from the factory. view this: http://www.petitiononline.com/VWSludge/petition.html and this http://www.thesqueakywheel.com/compl...plaint6043.cfm or just type in "1.8T OIL SLUDGE" you'll get a million hits.

 

they actually extended the warranty on the motor to 10 years unlimited mileage cause of the oil sludge, but if you use synthetic, it wouldnt be a problem... the sludge comes from cooking the natural components of conventional oil.

 

what type of problems would i need to look for in a 98 a4 1.8t. Because there is one in my area i am thinking of buying

 

Timining Belt is the biggest. Suggested to be changed at 70-80k. While you in there might as well do the waterpump.

 

Why do the waterpump if it is still working?

 

The water pumps, they are very hard to distinguish if it works or not.
its easier to pay 70 buks for it to be over.

like O2 sensors they dont have a regular yes no system.
Water pumps, life:
new - works great, almost 90%
as it gets older, the corosion hapens and the berings go nuts, no leakage - bum 75%
leaking nasty, woops - 50%
really leaking not a drop a day like a cup - 25%
if lukky and it leaks but does not go nuts.
later it go nuts meaning it has a huge luft - 10% or less
Woops too late, 0% Cheap bustard

as you see it goes out relativly fast.

Just invest some and get more back. mmmK.
