The Random E46/ZHP Question Thread

[JPMo]

so just curious with the recent heat wave we're having out in the Mid atlantic/North East, what would I need to do to spruce up the AC? Its currently working fine but I doubt its ever been maintained and a little extra cooling never hurt anyone.

Likely nothing. They're sealed systems that shouldn't leak. If there is a significant difference between the left and right center vents then you're low on refrigerant.

I've heard a mechanic who says he worked on A/C growing up, say that you can adjust the expansion valve to make the A/C colder. Apparently there are tips and tricks out there. Might be worth looking into, although i would imagine any kind of adjustment would require that you evacuate the system first.

Is Duralast 94R DLG a good option for a replacement battery or are there better ones out there?

Checked it out. What is this all about?

CONS:
- As it is the AGM battery, it can be used only for the AGM supported vehicles.
- Once the car owners are using the AGM battery for your car, truck, or other auto, it cannot be changed to use the conventional type of battery.

I dunno. I just remember researching batteries and that one was good.

Sounds like malarky to me. Our cars don't require any kind of coding for the battery that I know of, and I don't think they come with AGM batteries from the factory. I converted mine to AGM without issue, and feel confident everything would be fine if I went back.

I have a feeling that's just a Cover Your Ass statement for the cars where this might cause a problem.

That's probably it. I remember seeing that the e90+ have to have the battery coded to the car after a swap. Another point for the 12+ year old cars.

That's not really a big deal though since the software is so easily available. There are benefits to battery registration if I understand them correctly.
