Just hit 100k

Okay so I just hit 100k on my 2005 330ci. I am looking to put some money into the car on a few mods and such but first I want to take care of all of the prevenative maint. I know the cooling system should be replaced but what else should I look into or get checked out? Should I have the cooling system checked to make sure it was not already replaced? I have only had the car about three weeks. Everything looks brand new under the hood but I know that doesnt mean anything. Any help would be greatly appreciated as I am a brand new bmw owner.

well replacing the entire cooling system whether it needs it or not is a good place to start blowing money. I think the consensus here on the board would to replace w/o checking/inspecting/learning anything, after that, maybe start tinkering with the intake system and see if you can get yourself a few codes and a rough idle.
Automatic? It's an 05 so that trans might go out on you, I'd go ahead and replace.

Why not take some time to inspect your car, and sure the cooling system, replace what needs replacing rather than just flushing money down the toilet? Actually....that could be a good mod.. a money toilet in the back seat of the e46 for money to go down.

Glad you asked!

Start reviewing all that is on this list:

http://forum.e46fanatics.com/showthr...nerable&page=3

Then use your judgement to piece together where you think your car stands with regard to its condition.
Do you have any service records?

Wow your a special person!

I made it clear that I am looking for advise without just blowing money. I also made it very clear that I am a new bmw owner and would like some direction.

I'm at about 98500 miles right now.

In the next few monthes I hope to accomplish the following:
Oil change, at about 7500 miles, not too comfortable with 15k mile intervals.
Valve cover gasket change & vanos seals while I'm in there.
Entire cooling system overhaul, see stickied thread.
Spark plugs
Oil filter housing gasket

I think that's everything I have in mine.

I've always done the 7500 interval too, something about going 15k with the same oil just makes me feel uneasy.

Welcome to the forum. You will find some helpful people here as well as some complete a**holes.

I suggest you check your belts, pulleys and tensioners. The cooling system is a weak spot on these cars and the expansion tank in particular. When I acquire a used car I generally change all the fluids: engine oil, coolant, brake, gearbox, differential, power steering, unless I have proof that the previous owner has changed them. Same with filters: engine, cabin, fuel filters should be replaced if not changed recently.

Apologies for being an a$$hat in that post. I could have said "if there's nothing wrong, why are you fixing it?" and come off a lot better.
Put simply, there's a lot of people on here posting just rip out the cooling system/ccv/etc when there's nothing wrong. I shouldn't let it bother me, and apologize for coming in and giving you a crappy reception here.
GL with car and if I may try again, if you don't want your car to become a money pit, which it can, and quickly, dont just replace stuff at random.

Thanks for the apology but I completly understand where you are comming from. I keep reading replace this and that blah blah, well that just seems dumb to me because why would you replace something that is not broken. I am going to take a real close look at the car this monday and then on tuesday take it in to have it gone through and see what I come up with and what the service people come up with. I would prefer to do most if not all the maint on the car myself if possible just so I can become more familiar with the car.

I'll give you my extreme example. I drive cross country each year and am out for 9-10 thousand miles away from home with no place to work and no tools. I replace many parts at cost with my own free labor to cut down on the chance of being stranded in the middle of nowhere far from home. If I only traveled locally, my approach would be much different. On the road I'd be paying double the cost for parts and high costs for labor, and stuck in a town for days where I'm walking from a motel to the fast food joints. My car is my freedom!
So it's up to you to personally determine where in the reliability/cost conscious spectrum you lie.

Agree I have learned that these cars can be maintained for not a lot of money. As long as you keep an eye on things you'll be good. Welcome to forums

All it takes is one overheat and you're screwed! Hmmm, money for the cooling system, or money for the head or even engine?

Or I could spend no money at all and check the cooling system myself, what a novel idea

You really should tread a little more cautiously when others are reaching out to try to help you. Very possibly they know more than you do. If you've read so much here on cooling systems, you'll recall that our gauges are not analogue, and therefore do not give adequate notice for every overheat occasion. By the time the gauge reaches into the red, it is possible that you've lost your head at that point.
Most of the more experienced people here would not ride around using the temp gauge as an early warning device if their system had a known defect. They would cease driving until they repaired the defect.

Alright, is the sarcastic response really necessary?
Go ahead and just check it then. It's your problem not mine.
Sorry I couldn't be of any help.

Certainly never drive while overheating. No matter how close to home you are. I think everybody agrees on that.

above all get a cheap bmw scanner 1.4.0.....you will want to be able to scan your car by yourself...it is a pa soft knock off. mine paid for itself 3 times the first day...it reads and turns off lights
The way you can tell if your cooling system has been replaced or not could be.....look at the stick in the expansion tank.....if it is brown or aged it probably has not been touched.

The thermostat is electric and will never throw any codes....replace it because you could be over heating slightly and not know it causing pressure and heat.

The water pump is plastic and explodes internally....it throws plastic all over the cooling system and clogs it. Something you cannot inspect.

The radiator is aluminum crimped to plastic.....it goes out due to pressure and heat thermocycling. when it goes it goes.....you can inspect this if you take the expansion tank off to some extent by looking at white traces of fluid on the seams.

the expansion tank is just cheap....we replace these because they crack in a certain corner. some crack every 15000 miles. The bleeder screws are plastic and break and we replace them with metal. Replace the cap

If the car over heats 1 time the engine is done. that is why we stress on just maintaining it. The gauge is more like a switch....it will only read from 75 to 220....by the time you see it move the car is already overheating....shut it off and dont drive it.

.......change the transmission fluid.....it is broken down if it is an automatic and has never been changed....they call it lifetime....it has the consistency of water at 100,000 miles. the lubricating abilities become useless. Valvoline max life will be fine. i put 25 quarts of red fluid in mine and still didnt get all of the old stuff out. I did get 95% out and will change it again in 30,000 miles

...check your side trim and tail light lenses...cheap glue makes them fall off

I replaced the ccv on mine....it cause a vacuum leak and lets moisture into the intake.....at 100,000 it becomes a liability....they also get clogged in colder climates. They cause pressure on the valve cover gaskets when they go bad. The design is horrible...the location is more so...bavarian auto shows you how to change this on you tube.

Replace every vacuum line on the car....mine were deteriorated in every spot on the engine. including the fuel filter vac line....due to the high heat the car runs at.....which is why cooling system fails....I ran a mechanical thermostat.....and the $200 lifteime water pump.

I replaced the fuel filter and spark plugs. dont use bosch...get the ngk...my gas mileage was worse with bosch. ..


The oil filter housing gasket leaks....Mine was starting to....replaced it with the cooling system.....and on and on and on.

Common things to look for
front bushings
1 of the 2 fuel sending units go bad
shocks leaking
look for water under the spare tire
abs module goes bad (expensive to fix)
Hazard light switch wont work....look it up...easy to fix
frame cracks.....worst nightmare....common on 99 to 01 and still on 02, 03
o2 sensors (4 of them) get worse over time...they dont go bad but become ineffective giving lean conditions and bad mileage.
self leveling head light motors break
vanos seals
valve cover gasket.....

passenger side air bag sensor pad....dont replace it bypass it if it goes....there are 2 circuits....dont get the ebay one...make sure the bag stays active

I bought my car in january and found 80% of these problems. a lot of these cars fall apart after 100,000. I still like my 330ci....but i do work on it a lot.....more so than anything else ive owned.
