Any thing other than pump/t-stat failure?

MikeE90NC · 12-18-2014, 09:26 AM

Hi all! Well, the other day was driving along and minding my business when I stopped at an intersection. Happened to notice the engine fan was running full blast (oh hell I thought to myself) and sure enough, shortly there after the yellow water temp light came on.

EDIT:
Would this be a solid indication of the pump being bad? Is there something else I should look into first? If its the pump I need to order it ASAP. Just dont want to order until I know for certain (obviously). HELP!

2E82 Electric coolant pump cutoff, over-current
29F3
2AAF
3100
2A7C - vanos, probably need cleaning?

MikeE90NC · 12-18-2014, 01:02 PM

Bump

I guess more of the question would be do both 2e81 and 2e82 need to be present to indicate pump failure or can they show up individually?

Hows your battery?

1st code is a Coolant Pump code
2nd code is Fuel Pressure
3rd is Fuel Pump Plausibility
4th is what seems like a failsafe mode code
5th Vanos

Thats alot of varying codes. Check the status of your battery, dying batteries are known to cause lots of weird codes.

If your vehicle is a 2007 and you haven't had the water pump replaced it's likely time. They typically fail by the 75,000 miles range. If you haven't change the vanos you can try cleaning them first but with that mileage I would probably just replace them for peace of mind since you are already in there.

Thanks for the responses! I'll go home and check the battery first and take things from there. I agree that it is probably just time for the pump to be replaced however.

Checked the battery yesterday and the light was black. Gonna get a new battery first and start there, what are the chances the battery could be causing this?
