Hello A4 enthusiasts! This is my first time to the forum and I am hoping some of you can help me here. I have been to many dealers and I question their so-called expertise. Whenever I take my car from the dealer, I feel I am just paying for a very expensive car wash! [sm=smiley24.gif] I love my A4 and it has about 83k miles. I am very meticulous on maintenance and oil changes. I intend to keep it for awhile (over 100k) .

Anyhow, here is my issue: The oil pressure warning appears whenever the weather is warm (over 65 degress). When the oil temp goes above 225 degrees, the warning appears. This usually appears when I am idling in traffic and it disappears when I start driving. The warning light becomes more frequent when it gets hot and humid in Chicago and I have the air conditioner running. I have raised the to the dealer a number of times. They are unable to reproduce the symptom and the only thing they can produce is an invoice. [:@] Often times, they tell me to make sure my oil is filled up which I think is load of crap.

What do you folks think is causing the problem here? I appreciate any input you can offer!!!

 

eek. bad news. pull the pan and check the pickup filter. it is what pulls the oil from the pan. maybe oil pump is goin out. can't really tell without seein it first hand

 

dang, that oil light is no joke. be careful

 

vag it see what it says, maybe a sluge problem

 

Great input! I appreciate the feedback so far.

Here are some of my comments: If it is related to the oil pump, would I not expect to see this behavior during the cooler, winter seasons. I seem to lean towards the comment of BadLuckAudi , it does exhibit the symptom of an engine sludge problem. But here are my follow up questions:

1) What approach should I take in addressing this problem? Can I take care of it myself vs. going to the dealer?

2) I noticed this is common problem with 1.8T. How could this have happenned with the 2.8? I have always used Mobil 5w30 synthetic oil whenever I performed my oil change and other times, it has been the dealer. I guess what I am trying to get at is how can I prevent from happenning in the future.
