Ok, bascailly I was going along the motorway, quite high revs, then engine light started to flash, car was just burbling when i put my foot on the gas..
pulled over, cylinder 4 missfire was the code, took our the coil and cylinder 4 was full with water.
white smoke out the back ... im thinking its the head gaskett .. or could water of gotten in some other way?
car drives at low speeds but when coming on boost is just doesnt boost up.
i havn't driven it since..
just wondering basically given my brief description anyone could assist in narrowing down the problem?
Its going into seat in a week or so. Just hope there is no other damage.
any ideas or help ?
cheers
-
How was the coolant level looking? Or how is it looking....
-
Do you mean water in the cylinder or water on top of the spark plug in the coil pack chamber?
Just in the coil pack chamber then dry it out - may blow compressed air in.
-
Did you find out what the fuel leak was etc after the 'jump'??
-
snap - im loosing coolant somwhere somehow, it has defo gone down and exhaust smoking.
vt - water in chamber on top of spark plug i sucked it out with a straw (yum) and im leaving it to dry for a few days before i get a new coil in there and start it up for the 1st time.
the strange thing is trying to work out why it wont come on boost? and how and why the water got in there?
jon - nope no more fuel issues since sump was replaced maybe your thinking of other k1

Ohh sorry mate, yeah must be, I know your user names are pretty close..
Hmm, I would say do all the normal bits, check for codes etc.. Does it pull as normal before it comes on boost?? Also, pull off the PCV recirc hose (and block off the inlet manifold) and check for excessive vapor from the PCV
Does the smoke have a scent to it? And is it water smoke (ie very white??)

no more fault codes come up other than the misfire which was caused by the water..
car pulls fine untill turbo spools and then just doesnt pull anymore but i havnt tried driving it since clearing out the water etc...
ill tru the pcv and yes smoke is white and just chugs out when i start it (again though this was before i cleared out the water)
so ill leave for a few more days to dry and need to work out how water got in there, if its the head gasket gone what other damage and repair bills can i be expected to pay?

Sounds like head gasket really.. Unless there is some way the water gallerys in the turbo have fractured and its pulled in water from the intake side of the turbo!? I dont know if thats really very possible though..
Head gasket is a couple of days work, although you should skim the head at the same time really but thats only £50 or so.. I would say £400 in labour and another £100 or so in parts..

Good theory, could be true its been wet lately and all that melted snow had to go somewhere lol but its lost coolant yes and car hasnt really felt like its pulling right lately.
Its the ballache of seat trying to diagnose the problem for a few days then charging me for the pleasure.
-
belsy got his headgasket done by AMD recently, you might wanna give him a call
-
Has the coolant got the gungy mayo look to it ?, if so i would say headgasket has gone.
-
Coolant looks ok and no traces of mayo etc, the car is only a year old lol its bad if HG goes even with increased boost etc but lets hope seat can narrow it down first..
what at the warantee stipulations here, like will i have to pay for the time they spend trying to locate the problem? etc
-
Depends very much on your dealer. Some may very well tell you they'll not touch it at all if they realise it's running 360hp :evilgrin:
-
id get the map and everything else taken off before seat even look at it, i remember a lad broke his engine and seat wouldnt touch it as it had been mapped. :scared:
also car has probably gone into limp mode to protect the turbo from damage. thats why no boost. :smiley:
-
do a compression test . or leak down test
-
i work in a dealer just remove any traces you can of modification specially to the engine then just try your luck at worst they will charge you a hour at most for diagnosis then its up to you to give go ahead for further work as stated before cars probably running in limp home mode to protect
-
Car isnt in limp mode. well i dont think it is.. there is no lights on the dash to tell me its in limp mode plus all errors have been cleared.
-
mine was going in and out of limp mode on the way to the nurburgring, no lights were coming up on my dash either. :smiley:
-
Hmm interesting... only time will tell, once i get it to seat in a week or so, the main tech is on holiday and i dont want any of the apprentices looking at it
standard map back on it now, water cleared from chamber so over weekend ill start it up and see whats what

Ok just an update
dealer is looking at car and to find prob i will be charged 100quid.
then if it needs a new head or whatever, due to the mods i will have to pay..
then try to claim back through warantee but its "unlikely"..
only visible mod is air filer..
:confused:
-
any more updates??
my car was sat for a week last week and i lost coolent?? car runs fine though, but the water must have gone somewhere??
-
Car sorted.
they replaced 2 coils and the maf sensor and its good as new.
all done under warantee :congrats:
