Hi my car is 2001 aum motor coded audi 1.8 T dbw ı have revo since 8 months for last 20 k km. my coil pack failed failed for about 4 months ago and i changed all of them also my dump valve failed and i changed it with a forge one and next i changed my maf due to the low reading ..... my downpipe and cat are standart only ı have noe middle silencer and end one is remus .....
now ı have 2 problems ....

1. is my coil packs are allways trying to escape i have read about this before but i couldnt fix it every day i open my engine bay one or two coil pack goes a little bit up from the engine i push them back but after a 10 km it goes up again .... why do you think is this

2. my car is throwing water from end silencer (h20) :) after driving and heating the car to 90 c degrees when i stop a little bit for example for 5 min at idle my car begin to throw white smoke from silencer when i pust the throttle it throws out real water with white smoke ( i checked it with hand my hand doest smell anything it was colorless and doesn taste :) ) i check the oil water and other things nothing become less everything seems ok ..... my car only do this only after 2 min idle does anyone experience sth like this before ......

i changed the fuel and tried other things but could not solve this ....


thank u for your patience for reading long problem story and sorry for my poor english ....
 
1. Are your spark plugs done up tight? Try putting someting down the side of the coil pack when you fit it so that any air trapped can make it's way out. When the air expands with the heat it will have a tendancy to blow the coil pack out.

2. Water is a product of internal combustion. It will condense in a cold exhaust and only after a good distance will it evapourate completely. I found my Cupra would get the water to 90degrees pretty fast, certainly before the exhaust gets heated up enough to get rid of the condensation.

In my experience stainless exhausts seem to emit much more 'steam' than mild steel ones. I have no explanation why.

When you come to idle the gas flow drops significantly and I guess the condensation can build again. My advice is not to worry, unless the water leevl in the cooling system is dropping.

No probs with your English, much better than any of us would mangae in your native language.

Isn't the function of the cat to produce CO2 and water? So once you heat the water you get steam as said above.
 
hi thanks for answers .... my spark plugs are oke i changed them 2 times to be sure ... there is little hole on the coil pack that air can escape but i think it doesnt work i ll try your sugesstion

about the water production ..... my coolant level is same from the day i changed it since 6 months ...
can it be that my cat become old and condensation become so high ?


thamks for answers ....

You get the water anyway without a CAT, thats what rots exhausts on cars that do short journeys all the time.

Admittedly another byproduct of the CATs operation is water, its primary role is to clean the exhaust emissions.

EDIT I think if your CAT was bad it would produce less water not more.
 
sounds like a fecked turbo to me if there is no water mixing/escaping.
I'm not sure on your car, but my coil packs are bolted down, are yours supposed to be push fit?
 
thats the point that i really mixed up i take my car to emission test and the CO was really so less then normal also co2 that means my cat working so good but i could not say where does this huge water is coming from :) so i can say that i dont have any problems becouse my coolant and my oil level is ok and not changing ..... (my friend make jokes like my car can feed a dam .... )

my turbo is boosting normal what can be the relation between the turbo and water producing ? i couldnt imagine it ...

my coilpack is push fit style ... in early models it is bolted but my cars are not
 
i have noticed the same on my cupra r, only on short trips though. i notice what appears to be steam coming from the exhaust and it continues to flow out (only very little but still noticable) after the engine s switched off. is this normal as discussd above? im sory if its a stupid question but i've only just bought the car and i have no experience with used turbos. i've checked levels and all is fine.
 
hi zex i have sold that caR but to give you some advices that a3 still makes the same steam and nothing happenS everything seems fine a friend bought it from me .and used 30.000 km from the day i have posted the firs message to this title .... Dont worry about it like i did .... no turbo problems no other problems just nature :)
