so thought i'd post this in here since i'm not sure how many of you read up in the Maintenance section. but about 2 months ago my car started overheating....ended up being the water pump. at that time, the water pump and thermostat were replaced, and i was back on the road. fast forward to today, and my car sits broke down in the garage......same overheating issue. i checked the codes and have all 3 water pump codes P2E83, P2E84, P2E85.

are any of you FBO'd guys experiencing issues like this? i know quite a few of you push your cars a lot harder than i ever have.....so i'm just curious if anyone else has ran into this issue. my car only has 18k miles on it in close to 4 years.

ps JP got me scared with all the electrical issues he was having.

BMW's alone are notorious for water pump failures.

IMO something isn't right. i've owned 2 N54 vehicles now, i had the first one through 67k miles, my e90 now has 40k miles. no electric water pump issues on either car. two failures pretty close together on a low-mileage car is suspect of another issue at hand. i doubt being FBO/tuned makes a difference, either.

I have 9000 miles on my 07 which are hard driven miles. I had mine fail at 8000 miles and so far no issues but it's only 1000 miles later. These pumps are cheap to begin with. I hope it last longer than the 8000 miles on the original one. This is total BS

[shyestsparks]

We had to replace mine at about 55k.

that really sucks. thing is i had a track day planned for this past weekend too...guess it's a good thing the car broke down close to home than at the track. what boggles my mind is that i had less than 1000 miles on this new pump....what are the chances it was a faulty pump? probably slim....but who knows.

Damn 1000 miles and it happen again. That's is messed up. It's not a cheap part either. But having all three codes which is odd since when mine went it threw two codes weeks apart. First one was 2e81 and then 2e84. Total of 3 weeks after seeing these two codes the car overheated. Getting all three and then overheating so quickly after the codes is a concern

The old ones yes, but I don't know if anyone can say that about the new electric water pumps. They don't seem to be too prevalent...yet.

Seems the 328's and 330's have them fail just as much as the 335's, so I don't think its a problem with being tuned. For the OP's case, very possible you just got a bad unit, or maybe another side issue that's causing it to work too hard and prematurely failing.

The controller is the ecu.

Well def the old models. But its common practice for the N54 especially the early 2007 models to have overheating and cooling issues.

They later updated the equipment and software but there is still an inherent flaw in BMW cooling all around. My .02

I never had any other car with cooling problems, only BMW's.

[rismo]

I have had as much waterpumps as HPFP.... and my climate is not extreme hot...

BMW and Car = love
BMW and pumps = bad news...

They guy who owns the dyno where I go... his wife drives a 335i and she had to have hers replaced as well. She is totally stock and doesn't drive hard. Hers is a 2007; having said that, I believe I have only heard of failures on 2007 model 335i's. He said the one he put on looked the same but had a different part or model number (or something like that).

I have an 2008 model (October 2007 build) and had my water pump fail around 40k miles. It gave no signs or codes prior. I'm FBO. currently at 51k and haven't had any more issues with it.

[cn555ic]

Hmmm maybe it is a defective 2007 part but OP just replaced his and it already failed. Wonder if he got a old stock pump.

[samchoi604]

what year is your 335i? Have oil cooler?

Ever done a coolant change? I think the aggressive/race map makes the pump run harder too.

mine is a 08'....FEB 08 build date....and i do have stock oil cooler.

coolant change was done less than a 1k miles ago when the water pump failed the first time. i'm hoping i just got a bad pump...otherwise i have no idea what the issue is. i was at the track end of Oct running the Cobb Race map...and the car ran flawlessly. for daily driving i run the Stg 2+ FMIC Agressive. at the time of the first failure....i was running a Procede.

I see. I'm 90% sure you got a bad pump. BMW refurbishes these parts (like turbos and fuel pumps) so it is not unlikely that the part is flawed.

I am still on my original and have over 100K

[jlcolon2001]

I replaced the water pump and thermostat 2 weeks ago. My car is a E92 2007, no oil cooler, 39k miles aprox. with DCI and JB4. It overheated and threw 3 ECU codes, 2E81, 2E82 and 2E83.

[Mahhvinn]

I'm at 59k and my water pump went out last week. I had Injen DCI and RSD Charge pipe w/ HKS BOV and Vanguard exhaust.

[BlueLion]

ive got an 07 with 60K miles with the stock oil cooler no water pump issues

Awesome!

Reviving an old thread, but just to add mine (for newbies).... Mine's an '07 E90, just about to turn 98k, temp indicator came on yellow, turned red w/limp, then turned yellow, then went away. Threw codes 2E81,82,83. Taking it in today assuming I'll get a new pump and hopefully new thermostat (if warranty will cover). I'll have a newly rebuilt car in no time - just had vanos unit, cam ledge bearings, vanos solenoid - exhaust side - replaced a week ago and rear pass. door window regulator a week prior to that. Git 'er dun before warranty expires! lol
