Is INPA a free program?

Probably wise to pick up a few of the smaller coolant lines, like for the EGR cooler. I gambled and didn't replace any thing other than the water pump and T-stat. So far, no leaks. My water pump was just starting to get a little play in it.

The coolant has to be drained? How much did the parts cost you?

OEM parts were around 250 for the water pump and thermostat. I've seen where others got the job done at an independent shop for around $500-$800. I don't mean to sound rude, but if you have to ask if the coolant is drained to do the job, you might be better off paying someone to do it.


Here's my notes from the job:

Based on the description in post 180 in this thread:

I removed this hose connection after triple checking that it actually would contain engine coolant. This drain things fairly nicely and was relatively easy to catch the drain off:



I thought it prudent to protect the back of the radiator core with some cardboard, since I'd be working in the vicinity all day.



I discovered that the rubber portion of my charge pipe is saturated with oil, and the reinforcement rings have migrated. I've put them back where they belong, but obviously this piece needs to go on my short list. It seems that the excess oil in the intake is causing the rubber to break down.




This car seems to have the ORIGINAL Egr cooler from 2009.





I let the engine idle and bled the coolant out until I stopped seeing air coming back. The engine got up to about 55°C while idling.



And success!!!



PS: I did not get to replacing the glow module today. I got a late start and decided I just wouldn't have time.

I also discovered a notable amount of soot around the low pressure EGR housing. And some at the turbo wastegate shaft nearby. I need to figure out where that's leaking.

PPS: if you buy the OEM thermostat, it comes with the gasket preinstalled. You don't have to buy one in addition like I did.

I also, somehow ordered only one O-ring for the various connectors that have to come apart, and in my infinite stupidity, ordered the only one hat comes with the thermostat.

Here's my notes from the job:

Hey thanks for the input. I do most of the maintenance myself on my cars and truck. Changing the thermostat would be my first time, so I asked. It's better I find out everything I need for the job now instead of learning the hard way lol nothing is hard to do on your own, unless it requires special tools that cost a fortune, than I'll have a shop do it. Another noob question, any reason why you replaced the water pump? Or do they tend to leak at this mileage?

The water pump is right there. It's one of those "while you're in there" things. And the change interval is about the same as the thermostat.

With 121k miles, mine wasn't leaking, but there was some play developing in the bearing. So I'm glad I did change it.

You can't really purchase INPA, but when you buy the cable it typically comes with a software disc that includes a bootleg copy.

Just make sure you get the right cable for e70. It needs the D-CAN bus.

Sounds good, so basically any of those softwares would be better than autozone readers?

Yes, it will give you the BMW specific definitions for the error codes, as well as let you see real time data.

Getting the software set up initially can be a small pain. But if you are familiar with windows, and have the ability to google solutions to any hang-ups ou might encounter, it's not bad.

When I recently unpadted mine, I had a small issue with the 2nd step if he install failing. It turned out it was because the folder names on the disc had characters that the installer didn't recognize. I had to copy the folders off the disc and rename them to continue.

Thanks, I'll have to order one.
