So I was driving to work this morning with tiptronic and I stopped at a red light. It was fine for about 10 seconds and then the car starting vibrating violently. It felt like the pistons was pushing really hard. Then the check engine light started FLASHING. I pulled over and turned off the car and turned it back on... everything was fine.. I drove off in tiptronic and didn't have a problem for the rest of the way to work (4 miles). When I pulled into the parking lot I let the car rest for 2 mins before shutting off the engine. after I shut off the engine I popped the hood and saw that the coolant was smoking... I twisted off the cap and it sounded like I was opening a carbonated drink... I recently filled up the coolant (without flushing it) to the "Max" line because it was UNDER the "Min" line... But when I popped the hood today the coolant was well over the "Max" line...

What should I do?

Should I flush the coolant and refill it all over again? If so,how do I flush the coolant?

 

The 3.0L leaks coolant on the rear cross over pipe, there is a small nipple that needs to be replaced i bet.
As for the shaking its not related, sounds like a bad coil pack. Have the codes scanned and see which cylinder is miss-firing.

 

how much would it cost to replace those parts?

 

I would buy all six coil packs online at www.ecstuning.com which will save you a big headache and money.
The nipple only needs a small washer which is less than $5, but it takes about 3 hours flat rate to change it if you have the dealer do it for you. Look behind the engine on the driver's side, you will see dried up coolant back there.

 

is it part number ES#6381 (OEM - Igntion Coil)

 

Man i don't know the part numbers, if its for a 3.0L engine your golden. I would just replace all of them because they suck.

 

lol this one:

 

I guess, if its under the 3.0L engine.

 

cool thanx

 

how much am I looking to spend for labor at a non-dealer service shop?
