Easiest thing to do is to go to an auto parts store like Advance Auto or AutoZone and get the codes read for free. Then post up what you find, or just google it.
BTW, Mobil 1's 5w-30 is not compliant with VW's required oil for the 2003 Passat (it's not 502.00 compliant). This could be a problem for you especially if your car is equipped with the 1.8T engine with the possibility of either sludging or coking the oil. I suggest that you go with Mobil 1's 0w-40 formula. Of course, that brings the possibility that your MIL is related to your choice in oil.

Oil choice can result in a MIL? That's surprising.
Anyway, I took it back to the place that changed the oil and they pulled an error code of 2181--cooling system performance. They reset it and yesterday it didn't come back on after about 30 miles of driving (15m each way to work). Of course, today it came back on after about 10 -15 mins of interstate driving. My mileage is 52k. Am I due a thermostat/water pump failure do you think?

My thinking on the oil and MIL lights would be this: oil related damage that finally surfaced. That doesn't seem to be the case.
Anyway, back to your code - VW does have a warranty extension on the coolant temperature sensor on the 2001 through 2003 Passats with the 1.8T engine.
Google "volkswagen recall coolant sensor". The first link that I found has a copy of the recall letter. Maybe you'll get this covered for free - worth looking into.
#2774 of 3341 Oil change and MIL indicator
Nov 08, 2008 (11:49 am)
I just recently added a quart of 100% synth oil to my Passat (1.8T) thinking it might help with the MIL indicator. The next day I drove it without any MIL. Then when I thought I had licked the problem, it came back on again. Now that I've been reading this forum, I do remember getting that letter in the mail from VW about the CTS. The problem is I'm a second owner with an excess of mileage covered in the warranty. We called VW and they told us it would cost $95 just to look at it to determine it's source. I'm going to see if Autozone or Advance will give me a free error code reading. Thanks for the info.

Anyone ever heard of anything like this, Thanks
#2776 of 3341 Coolant Disappearance
Nov 12, 2008 (8:14 am)
I have a 1999 Passat V6 (2.0 Liter engine) with 135,000 miles. Over the past few months we've been dealing with a coolant leak that cannot be located. I've had the car to our mechanic a number of times, and he's done two pressure tests, with the engine running and with it not running, and he even left the test to run all night on one occasion, but he gets no coolant loss during these test.
However, about every other week, I have to add 1 - 2 cups of coolant to the reservoir. I see no other signs of leakage. The mechanic also replaced the reservoir cap at one point, but that hasn't stopped it either.
Any ideas on what might be causing this?
#2777 of 3341 Stop! Low Oil Pressure indicator. 2003 1.8T
Nov 13, 2008 (5:26 pm)
This message appeared. Brought it into the dealership, they made me produce 7 oil change receipts and said the work would be covered by VW. Apparently Synthetic oil should be used exclusively. It's in the shop currently, they have warned me of potential engine damage. Should I be concerned? They said that there is considerable engine sludge and an intense flush and replacement of hoses from the engine is required.

I also have a 2003 1.8T and VW sent a letter a few years ago acknowleging possible oil sludge. Cannot remember if they did a recall also. VW should be responsible for fixing your problem. Do not let the dealership talk you into paying and trying to get reimbursed. They have done that to me several times. I only switched to synthetic oil this year when the mileage reached the 90,000's. I have never been told you have to use synthetic exclusively, rather they suggest when the mileage gets higher. Stand your ground with the dealership and good luck.

I'd be a lot more concerned if they hadn't said that VW was picking up the tab! Didn't you get this letter?
BTW, if you read your original owner's manual, you won't see the words "use synthetic oil." You will, however, see wording to use 5w-40 weight oil that meets certain VW specifications. 5w-40 only comes in synthetic.
