What would cause high pressure on the low side? This is after evaporator, compressor, expansion valve, accumulator, and condenser replacement, basically everything. Air is cool, but not cold, and won't keep you from sweating in this 90+ degree weather. I replaced everything, and then had the shop evacuate the system, recharge, add oil to compressor and perform leak test. I know a bad compressor could cause this, but is brand new. I replaced everything, so there should be no blockage anywhere, either. Thanks!
If Your AC Air Conditioning Is Blowing Warm or Hot Air Then READ THIS THREAD!

My AC couldn't keep up w/ the 90+ degree weather for a while either; I figured it was just a week AC in the E46s. HOWEVER, I recoded my IHKA with the euro coding, and it blows significantly cooler. I'm not sure why this would be, but I'm not complaining lol.
Same here, cold but not ice cold. The thermometer measured below 50F coming out of the central vents. So it's either too hot outside (between 90F and 100F) or my windows need to get tinted.
Does tint make a difference?
Count me among the lucky. I set everything up, verified the compressor was on and read 27 psi. After half a can the needle kept going back to 27. I turned off the AC, waited a few then turned it on again and hooked up the gauge to read 35. I'd say those gauges are cheap at best. Luckily those systems don't recharge quickly.

I'm sure tint makes a difference, but I don't have any. There aren't many that can (or are willing to) do it, but try having your cars Vehicle Order (VO/FA) changed so that your car identifies itself as a euro model, and then have the IHKA recoded. Made a huge difference for me. One of these days I'll compare the files so that I can substantiate the differences.
edit: I just compared the defaults between the two regions, and there's only one line that's different: "umluft_memory". Doesn't seem like that it'd be something that changes the cooling capacity. I would normally say my experience was placebo, but I had a number of people comment on the increased cooling capacity, and they have no idea about the kinds of things I do w/ coding on my car.
edit 2: The line doesn't have the implied change (my ihka unit maintains the memory of the ventilation settings whether or not the line is set to aktiv/nicht_aktiv). Perhaps that line really does change how the car cools the cabin
I have some other things i can sell you if you believe that.....
LOL never mind I see you post a few down
I bought some gauges and checked everything myself. Static pressure was 130 on both sides. Dynamic pressure at idle with AC on full blast and in recirculation mode, low = 65, high = 210. At 1500 RPM low = 40 and high = 290. Air is still cool, but not cold. Thoughts?

a/c
even though its no longer A/C time, i wanted to get some advice
for the past 4 yrs, i had problems with the passenger side blowing warm air and the driver's side blowing slightly cool to warm air. i would get the A/C recharged, however after one or two months the A/C would require another recharge.
now, a week after recharging during the hot summer days, I would notice that there is cold air blowing, however the passenger side is not as cold as the driver's side. both sides are never totally ICE COLD.
do I have a leak. do i need a new compressor?

Good luck with it staying like that. Hope you didn't overcharge the system.Just bought one can for $23.97 from walmart and put it in my car. My A/C is ice cold now. Great DIY....Thanks

A bit too high. You can find cheaper.
I was quoted 108 bucks at Pefferle tire in Hamilton today.
They also have a shop in Fairfield, if you're north of Cinci.
If not, you might try Bavarian Motors on Elsinore in downtown Cincinnati or Foreign Exchange in Dayton. I have taken both of my cars to both shops and they do wonderful work.
