Hello we have just down a full service on my bmw 316i compact sport
r reg, all plugs and filters have been changed new Castrol Edge Sport 0W-40 oil was used for the change,
we have noticed that coolant is empty yet again but was only top up a couple of weeks back and today its gone down another 5 levels since yesterday, the engine is hot alot more than i think it should but i have not actualy time this yet,
when i start the car it seems to lag a bit only on start up it runs fine when driven
can be shankey now and again.
i am thinking towards the head gasket but then there is no leaks anywere all oil and ant freeze and break fluid is spot on
raditor and water pump were changed by preivous owner in feb this year
i dont weather to just get it done gonna cost 拢300 for new head gasket but i dont wont to waste money if there is gonna be more problems but the car is a get drive and looks super lol
on another point the horn and elec mirrors our not working checked the horn no power is going to it any surgestions ?
thank you all for your time to read and help
Kindest Regards,
stephen
Water keeps going empty from the coolant.water drips from the exhaust?
Sounds like a regular coolant leak to me, run the engine from cold and check all coolant pipes, water pump and the radiator for leaks, or leave a newspaper underneath and check later for damp.
If the head gasket has gone you would probably notice either a lack of power (...Deep breath...volumetric efficiency is reduced as the compressed mixture exits the bore via the break in the gasket) or a milky residue on your engine dipstick (as water is getting into the engine block via the break in the gasket)
If the water pump was changed recently it could just be the water filling any air voids, keep a note of how much you've used.
Check for any overheating, up to 90 degrees c should be ok or 3 quarter across the gauge if no numbers, should never enter the red at any stage.
Garage can do a compression test to check head gasket before dismantling engine.
Horn could be anything, start simple..fuse? wire off? the switch?
Water drips from exhaust pretty normal as condensation and sometimes unspent fuel.
Good luck.

take it some where and have it pressure tested, the water coming out of tail pipe is normal you make 1 gallon of water for each gallon of gas used, if it was head gasket it would blow white smoke out of the tail pipe and it would smell sweet and hang in air like a cloud, you probley have a small leak possible hose or some thing
condensation on warm up can be normal on a lot of cars, as you have Other electrical things not working, check the electric fan is coming on. it can be amazing the cooling effect the air flow when travelling has. check the electric fan is coming on when it should. the thermo switch is worth checking if it douse not come on
If there is a white residue in the engine oil,check oil cap/oil filter then there is water getting into it.Sites below may be of some help.
Check your oil dipstick; if it looks like coffee with creamer in it, You've got a blown head gasket or intake manifold gasket.
Horn- relay is out.
Mirrors-fuse.
put new coolant in check tht the waterpump has no leaks and that there are no holes in the tubes making a lack of air presur
Sick car, get help fast. Don't let it overheat or you will be burying it.
Sounds like the head gasket is leaking. Good luck!
You should first check there is not a vapour lock in the radiator as it has just been renewed ,as well as the water pump ,it looks as though the last owner was having the same trouble and tried to sort it.Check your in car heater unit,that may be leaking, under the carpets is a good place to check for the leak and it will smell of sweet anti freeze in the car.If that is not the fault then it is the head gasket for sure.Check each cylinder pressure to make sure before you tell them to renew the head gasket.
The coolant is getting into your cylinders via a failed cylinder head gasket, being turned to steam, condensing in your exhaust pipe and dripping out. It will need urgent repair.
The leak is internal, so you cant see it from outside. A cylinder head gasket should cost about 拢25 to buy, but If you have it replaced at a garage, it's gonna cost you for labour charges, and that will be 拢200+
One point, I fail to see how your anti freeze can be 'spot on' if your coolant is leaking away... The anti freeze... IS the coolant ?
Find an indipendant BMW specialist, not a main dealer, it will cost less. (failing that, buy a haynes manual, and DIY)
