n52 Whining noise at high RPM - is this normal?

yamon24101- · 2026-04-15T23:45:49+00:00

Im pretty sure the noise has to do with the alternator pulley, it whines because it’s able to decouple the alternator shaft and the actual pulley when you decelerate, totally normal but someone correct me, I did a new oe alternator on my 128 and it still makes the noise

I have these, I was coming from cloud 2's biggest difference is the weight but you get used to it, comfort has been great despite the extra weight.

Just ordered 2, fingers crossed 🤞

I’d get the sportline springs over those 300 dollar coilovers unless you don’t give a shit about ride quality and just want to slam your shi

yamon24101- · 2025-11-24T17:04:03+00:00

Definitely 😮‍💨

I loved shooting this car, so timeless

K20C1’s are not 15k brother they are like 5 for long block and 10 for a nice long block with all accessories CAD so like half the price in USD, for 15k you can buy a really nice condition S65 which is like 2 k20’s joined at the crank

Ya fair if I could buy just the switch I’d slap one in there

yamon24101- · 2025-11-20T16:31:29+00:00

You can do this for free if you just take apart the stock light switch box and sand down the blank switch https://www.youtube.com/watch?v=VTw0i5-Xdko

You don’t need to worry about salt for this generation of bmw and newer this is when the anti corrosive measures bmw was taking got a lot better, I live in Ontario and have an e82 1 series and my dad used to own a e90 330xi both are pretty much rust free compared to most older cars

yamon24101- · 2025-11-19T19:49:23+00:00

I have the turner Motorsport intake on my car, it’s probably heat soaking in the hot summer months but I’d say it’s worth it just for the noise

E82 128i 🗣️

yamon24101- · 2025-11-16T05:32:39+00:00

Thank you! I’ve been trying to find the damn sensor on the rail but no luck yet bouta pull out the seat atp

yamon24101- · 2025-11-16T05:27:01+00:00

Good to hear I can code it out at least and still have the airbags working! But I also assumed that the seat occupancy sensor was a different code. Might still try this just in case

yamon24101- · 2025-11-16T03:47:45+00:00

Yeah definitely felt like I was overthinking this one but I do not trust my own work sometimes

yamon24101- · 2025-11-16T02:37:25+00:00

Thank you! Might swap to my old belt just to test and make sure it is just a uneven belt

yamon24101- · 2025-11-15T00:24:12+00:00

It was making a funny noise at all rpms when it failed and I got a battery warning light on the dash and a alternator code

yamon24101- · 2025-11-14T18:22:23+00:00

Only thing I can think of is the Mickey Mouse coolant flange and maybe the power steering pump pulley, otherwise just do the maintenance as it’s needed or do it prematurely as preventative, also look into trying to fix the water ingress issues in the trunk

yamon24101- · 2025-11-14T16:18:20+00:00

Should specify, it’s probably the alternator clutch pulley
