For 5 years and 80+k miles , my car was a dream and needed nothing but routine maintenance.This 6th year, though, has seen the turbo go boom (warranteed, thank god), the timing belt go snap(not warranteed- :cry: ), the brake-abs light started flashing(not fixed yet,i need $1300 more than i need abs) and just today on the way home, gently pulling away from a stop sign, a CEL started flashing and the engine felt like it was vibrating like crazy under the hood, like an unbalanced spin cycle load in a washer.. I limped home the mile back to my house and am having the car towed to the dealership tonight.I just had a whole new head installed by the dealer from the TB incident.When i checked under the hood, a cloud of burnt oil smoke rose up to greet me. I am hoping the problem originated from the new head install so that the repair will be covered :nervous:

Anybody have any predictions or wild guesses on the cause of my latest potential nightmare? Impress your fellow b5ers with your uncanny knowledge and insight of all things passat.I will update as events unfold and announce a winner as soon as i can.

Sorry to hear about the bad situation. I am thinking…possibly a broken motor mount? This would explain the washing machine behavior but not the burnt oil cloud and smell (unless the washing machine behavior was violent enough to slosh oil up into the cylinder walls with the engine running). You did not mention a low oil pressure light/indication with the CEL/MIL; therefore, I would rule out some type of oil pump failure.

The knock sensors should have picked up the excessive vibration from a broken motor mount. However, I do not know if the vibration sensor generates a MIL/CEL (steady or flashing) or simply an engine code.

From what I remember about MIL/CEL lights in general:
Flashing MIL/CEL = pull over and shut the engine down immediately
Locked in MIL/CEL = have the car looked at as soon as possible

mfitz, I am not trying to ridicule or make a bad situation worse. Members that may be reading your post may not know this about the different MIL/CEL light behavior.

A flashing CEL usually means some type of ignition problem and your engine is in danger. Misfiring is the most common issue.

Did it feel like the engine was ready to jump out of the car?
I've heard the symptoms of a bad ICM described this way.

My vote is for ICM or coil packs. A bad/fouled spark plug or four is another possibility.

Though if I only get one answer, it's the ICM.

Keep us posted.

A tie for first between blaupassat and notapreppie- it was the ICM. the CEL was for misfires. the dealer price for a new ICM was 386.00 :shock: BUT, thanks to info on this forum and the coincidence that at least 2 or three other b5ers are having this problem this week, i found the part at http://www.busdepot.com for 119.99. i just ordered the part tonight and should have it by monday .

I should mention that the car was at the dealer all day, and once they cleared the codes, they couldn't get the car to act up and throw a code or misfire again. they drove the car 5 or 6 times today trying to get it to happen. Of course when i came to pick up the car, it ran fine for about 1/2 a mile and started then misfiring and flashing the cel again.they looked at it again and swapped out the ICM and everything was fine.they let me leave the car at the dealership until i could get the part on my own, showing me where it was so i could do it myself when the part came in.the oil leak was traced to a small loose oil line which they tightened for no charge.they also didn't charge me for any diagnostic work or labor, knowing as they did that just a month ago i dropped $3300 there for a new head, and they still felt sorry for me.

overall not a great day, but this all could have been way far suckier.(and much more expensive)

Glad to hear it was not serious. I experienced a bad ICM early in my B5 ownership (25k I believe). I experienced the car shaking violently, but not the burnt oil cloud. However, you mentioned that the oil cloud was the result of a different problem.

BTW, not long after my ICM failed, my Mass Airflow Sensor (MAS/MAF) failed as well. The MAS failure mimicked the ICM failure, shaking and CEL/MIL, to the extent that I thought that the new ICM was bad. When I took the car to the dealership, they stated that the MAS was bad. The ICM failure occurred about the same day that I found ClubB5 and before I purchased a VAG-COM. :thumbup:

update : got the ignition control module from Bus Depot on monday 7/12 and plugged it in after work. I had a flashing CEL at first, though no sign of any further misfires, then the CEL stayed steadily lit for the 15 mile drive home from the dealer. This morning the CEL was off entirely. I was afraid i was going to have to bug a vag-com owner to clear the error code for me. :roll:

As mentioned in other ICM posts , the cheaper priced ICM is from Huco, not Bosch. Not mentioned however( AFAIK) is that the Huco model is not an exact fit. The bosch model has some spacers built into the unit which are not on the huco unit, meaning you need to either get shorter screws ( only two) or else some washers to build up the unit so that it tightens down snugly. Also of note is that the Huco unit seems to have a bigger heat sink in the base of the unit, so maybe it will last longer(?)
anyway, thanks to cb5 for saving me at least $230 :)

second update: my wife was the one who opened the package with the icm, and neglected to mention there were two screws in the package as well, along with the small tube of grease.it wasn't until later when i mentioned that the fit wasn't right etc. that she told me that two screws came with the unit :eek:h: They of course are the right size......
i searched through the packaging to find the grease as well, which she hadn't even seen.
