Waterpump failure?

BoostaVita · 11-20-2012, 06:46 PM

My 08 335xi (117K miles) broke down today. At first, I heard radiator fan running at high speed in the cabin, then the red engine overheat symbol comes up. I stopped the car immediately and have it towed back home. When I open the hood, there's leaked coolant around the coolant reservoir. Can anyone tell me if this is due to water pump failure or something else? Also, wonder if someone can recommend a trustworthy independent shop near southeast Connecticut or Rhode Island. Any help will be greatly appreciated. Thanks in advance.

Check codes if any but most likely its your water pump. Keep us posted

Thanks guys for the input. I just pulled the codes. They are:

2A17 - DMTL tank leakage (what's DMTL tank?)
2E82 - electric coolant pump cut-off, over-current
2E81 - electric coolant pump speed deviation
H2AAF, H2FCA, H2FDA, H2FDB - wonder what these codes mean?

They point to possible water pump failure. Anyone can tell me what's the cost of replacement (water pump, thermostat) at dealer vs. independent? Also why does coolant leak out of the reservoir when water pump fails (related to code 2A17)? Thanks.

yup water pump it is. as far as dmtl it is diagnostic module for tank leaks. can either be a loose gas cap or a dmtl pump that is bad. not related at all to water pump faults

yup, same thing happened to me. 2e82 and 2e81. new water pump + thermostat + labor was around 1000 bucks out of warranty. Have fun lol.

Thanks for the inputs. Don't know if i should leave the brave 100K+ miles N54 club now. The force is no longer strong with me.
