N54 water pump issues by model year.

themyst · 05-31-2012, 08:22 PM

Well when I did turbos on my car I did observe my water pump is plastic... Is that a good thing?

4/07 7000 miles!! Piece of shit crap out on me

Carl Morris · 05-31-2012, 08:51 PM

08 335xi, built in late 07. Went out at 60k. Replacement didn't make it out of the shop and another one had to be ordered. It's been fine so far.

I got to inspect the original. The impeller looked fine and the bearing were not loose. It was very hard to turn by hand, though.

my xi is right around the same as yours. I'm at almost 80k miles on the original water pump.

Traditionally on the E36 the water pump was plastic and the upgrade was metal. This might not help in this case but just something to work with.

jlcolon2001 · 05-31-2012, 09:06 PM

I replaced the water pump/thermostat combo @ 39k miles aprox. My car is a 335i 2007 (Build Date 07/06).

ADVANT123 · 06-01-2012, 07:38 AM

Waterpump/Thermostat failed on my 09 335xi @ 65k miles. Cost $800 in parts and $600 in labor to replace at dealer...

2doubleeagle · 06-01-2012, 07:48 AM

2008 E90 -- 8/2007 production, failed at 51k miles, replaced under cpo

omerfar23 · 06-01-2012, 08:31 AM

2008 335i failed at 40k. sucks

SPJ · 08-12-2012, 06:02 AM

07 335 failed at 62k

flexinator · 08-12-2012, 07:53 AM

08 335xi. Changed at 56k

Zebra99 · 08-12-2012, 08:20 AM

Ok so is there any confirmation of parts being changed or a re-design?

I'm at 82k km and I'm thinking mine has issues because my temps tend do go over 115-120 celcius on a 30 degree day which is ridiculous. Doesn't happen all the time, but it causes limp mode.

I have crazy WG rattle and figured if do the water pump too since adjusting them thy has to come out.

What do you guys think? Anyone have part #'s of what's needed?

Edit: 03/08 build.

07bmw335iguy · 08-12-2012, 08:38 AM

07 e90 335i at 98k

bceagle1991 · 08-12-2012, 08:39 AM

2010 335i failed at 43k. Also just this week at 45k my valve cover cracked, another plastic part that probably should not be plastic due to the heat under the hood.

ADVANT123 · 08-12-2012, 08:51 AM

09 335xi (07/2009 build) failed at 65k miles - 100% stock from day 1

Smokn944 · 08-12-2012, 10:33 AM

10/07 build water pump at 33000 then thermostat 400 miles later. Was still under 4/50k. Dealer changed both. Water pump failed, dealer said thermostat was fine. Then temp was never passing 180, 400 miles later went back and dealer said thermostat was stuck open.

VNeBLOB42 · 08-12-2012, 02:48 PM

this thread is depressing. i just hit 50k, July 07 build E92.

knock on wood, no water pump issues yet.

my buddy on here hit 52k water pump left him stranded, 07 E90 just a couple months ago.
