04 325 e46 help : ping/knock

Hey everyone, well this is what happened....

On monday last week driving home from work and we had a heavy rain and drove through a flooded spot as did a ton of other people and my motor took on water through the intake (after market) and engine bay drenched, now ...

Pull over checked under the hood everything from air filter, top of engine, cabin filter was drenched and a transmission light on and little bit of milkyness on the dip stick so now blowing white smoke briefly as the water was being burnt off, car is miss firing and making a piniging or knocking sound, so I call insurance and get the car towed to their compound, and this is where all the fun begins...

Thursday : Insurance company inspects the car and states that there are no signs of water in the intake tube and car runs fine and no milky color in oil and car runs fine....

Friday : The shop says.... car runs great nothing wrong with it, no milky coloring in oil and no signs of water in the intake and no transmission light....

after a afternoon reaming out insurance and the shop i go back to insurance and state "I have a video right after what happened and it shows the motor is running like a diesel on a bad day, miss firing and making a knocking/pinging sound from what appears to be the engine block from what i can hear"
Insurance company insists I goto the shop with the video, but they close within an hour and no way to get there, but rather I call them and ask again about what they have noted after their quick inspection, low and behold same answers... until I say "I have a video" then they change their tune to "oh there was a pinging knock but you have a vacuum leak and could be your MAF sensor" I told them well do you not think chances are if I had a vacuum leak my car would have ran like crap before this incident? and they had no comment

i ask do you know where this apparent vacuum leak is coming from, and they don't. so i state to them as well "well too bad i have video of the car running like complete ****"

now... I'm going tomorrow to the shop and if they say one more wrong thing I'm pulling the car out of there on spot with a tow truck.

Here is the video I have and any input as to what suggests that knock/ping sound would be great. thank you

Yeah, that video is set to private so we can not see it.

But it definitely seems like you got some water in there. Do you have a check engine light? Does the car run just like it did before you drove into the water?

I have no cel, no eml only a trans light which apparently is gone but I have heard insurance pulling shady things off to make sure they don't have to pay claims out. I once have had the maf freeze up and I had to pull it out and thaw/dry with a hair dryer but when it froze how ever it happened i have not the foggiest but it turned out a eml and cel

Wow, it sure didn't like that. I would (or would have) pull all the spark plugs and turn the engine over and over and over, so that the pistons shoot out the water from the spark plug holes.

How does she run today? Is it time to put in a sbc350??

I don't have the car in my possession yet it's still at the shop, I'm going down tomorrow and pulling the car out of there and paying out of my own pocket for another tow and another shop to inspect it, guy i know sent his car to this same shop same type of claim.. 3 weeks to look at it.. mine less than 24 hours like wtf ....

But my question too is will a MAF not always throw turns on cel and eml... aka limp mode

HELL yes.



On topic, did the shop change the oil for you? If the car runs fine currently AND if you didn't get too much water in (there wasn't a hydrolock which is good), you might ought to change the oil then drive it hard to burn out anything left over. Then change the oil again adding 7 qts. of LL01 spec'd oil and give it some time to develop more symptoms.

ya first thing i'm doing is checking out actually to make sure it has not been changed! reason because i want to send a sample off if i have to to prove the milky color is in fact water and not coolant from a fubered head gasket but if insurance changed it before i can then i'm pretty screwed literally, but i'll know more tommorow, my main focus and concern is this whole MAF and supposed VACUUM leak that i supposedly developed out of thin air and that is apparently not related to water...... because once I can get some solid info I can work with I'll be showing them the no lube policy
