The Random E46/ZHP Question Thread

The ZHP wasn't requiring frequent enough maintenance, huh?

Pretty much

I drove Peterman's 335i Mtech a few months back and haven't stopped thinking about the low end torque on that N54 and how solid & modern the car felt. The best description I've seen is that the torque on the N54 and N55 comes on so early that it feels like a naturally aspirated V8.

I want

Not an e46/ZHP question so I'm totes breaking the rules here, but it is a random ass question.

I'm going to look at a 2013 335is this weekend (because I hate myself) and the girl at the dealership grabbed a few pics before they washed it. This stuff was written on the rear quarter glass. Anyone know BMW dealership processing secrets enough to know what it means (@Sockethead)? It's an N54 engine, so I assume there's something about wastegate rattle in there...

Wife said it looks like the bottom right column might be what they have into the car. They usually fix what ever is broken before selling it.
Every dealer is different though could mean something entirely different.
Is it a BMW dealership?

Good call. It had some little "w" looking marks on different areas of the car too - maybe spots they wanted to hit with touch up or pdr?

It's at Century BMW over in Greenville SC

Ok get them to do a key read for the service records.
It should at least show the service done over the life of the factory warranty. If the car was serviced there after that, it will have that additional service record

Noice thanks brother

BTW, don't let anyone scare you away from the N54. It's an amazing engine, I'd rather have an N54 than an N55

So I get this sound when I pressed the AC button (which I guess turns on the compressor?) its like a creaky, cyclical type sound that is only present when the AC button is pressed. This video is exactly what i'm experiencing.

Lots of posts on e46F suggest the blower motor assembly, which to me doesn't make sense if the noise disappears when the AC button is off. Another post suggested low refrigerant but my AC is still cold. Someone else suggested the AC expansion valve (https://www.ecstuning.com/b-rein-par...503452759~ren/).

What do you all in the mafia think?

Set it on hella cold and see if there is a difference between the temp of the left and right center vents. If not, then compare the driver and passenger side vents nearest the windows. When the refrigerant gets low, the passenger side vent stops cooling first and then it spreads to the passenger side of the center vent, and so on.

Interesting, I'll definitely try that. Thanks!
