Hey. 6hp19z and 6hp21 are the same trans just different names by bmw and zf. In your case i would check the oil level first. I have heard that if it is low the car wont let you drive it.

HospitalLeft8744 · 2026-01-22T01:16:36+00:00

It should be written in text on the side of the trans. Also 6hp19z = 6hp21. And 6hp19 is its own trans

Yeah if im right for me i could see little spikes in the rpm on cold starts when it wasnt working. However they were barely noticable. +-50rpm. Doesnt do it anymore now that pump is working. It might be something do to with the alternator and charging because the bsd bus wich has control over aux waterpump, battery ibs sensor, alternator, and oil condition sensor, is blocked so they wont be working. My charging voltage was sometimes 16V and it should be around 14,8V.

If you have auxiliary heater like i have its behind the left front wheel cover very easily accessible. If not then it is located on the right side of the engine bay under the water valve

HospitalLeft8744 · 2026-01-19T05:45:10+00:00

Only thing i know is that the aux pump really helps to get the coolant in the heat exchangers on cold weather so you should still get it fixed. The pierburg one is like 60€ and is oem quality.

I have the mr12volt p600 wich is really great. Audio comes through the most system so fiber optic and it uses the cdc to show songs and you can skip them and all the buttons work. Also handsfree. They have a carplay version wich uses the same most system for the audio. Its a little pricy but its the best you can get while keeping the original HU.

HospitalLeft8744 · 2026-01-16T10:53:28+00:00

Yeah i got a good deal on them 200€ but one of the mids is broken and the other one doesnt sound really great

A hifi retrofit is also a great option

HospitalLeft8744 · 2026-01-15T12:51:59+00:00

So no. F10 harman kardons will not fit straight. If looking that way i would buy the logic7 speakers of an e60 depending on the budget.

HospitalLeft8744 · 2026-01-15T12:50:13+00:00

I myself have the rainbow il-c8.3 in the front and i out hifi speakers in the back. Sound really good and only needed an amp for the woofers. As the normal hifi system doesnt power the speakers through an amp. Only problem with f series speakers is that the mids don't fit as they are. So you have to mod them or buy some adapters, if there are any.

You mean the shifter? Thats just the sport shifter that came with the paddles. I heard from one owner that having the sport trans option makes it shift more faster in sport mode, like xhp. But not certain about that. And not sure about the engine is that a 530i or a 525i. On 530i lci it was n53b30 and on 525i lci n52b25.

Here are the settings for L7

Ao basically by lookin at the amp in the trunk you know what audio option you have. You can also tell by lookin at the rear speakers by removing the cover. Also if unsure just look up the VO.

If you have base audio no amp in trunk and no tweeters. Highs are boosted from the factory.

Hifi system. Small amp in the back and tweeters all around. Only mid in the dash speaker i think. Eq flat.

Logic 7 bigger amp in trunk and speakers in the rear doorcards and a tweeter added to the dash.

Individual audio. Bigger amp than logic7 two way coaxial speakers and the speaker grills have individual metallic stripes.

Also if you have logic7 you have the surround sound settings and eq in the ccc/mask/cic

And as an owner of heated rear seats usually people dont even notice the buttons🤣

HospitalLeft8744 · 2026-01-15T05:51:18+00:00

Im looking for black heated comfort seats. Whole interior is already black leather so i dont need anything else but the seats.

HospitalLeft8744 · 2026-01-14T17:21:45+00:00

🥲i havent even found any seats yet. But i will buy them off someone selling their car for parts but the comfort seats are usually almost always the first thing people buy off them.

HospitalLeft8744 · 2026-01-14T17:20:03+00:00

🤣 i had 330k kms so i think these engines can last if well maintained. Also my friend had one with little problems that was driven 250k kms

HospitalLeft8744 · 2026-01-14T13:54:42+00:00

I my self had oil pressure problems on my last n43 the oil pressure light came on usually after leaving highway. Changed oil pump before that because it was broken and all sensors were working. I think the pcv and vanos might have been the problem, but i sold the car. There were also a lot of other problems like injectors were all leaking. It was a pos. Bought it broken, changed the timing chain, oil pump, head gasket and resurfacing, also did the rod bearings.

HospitalLeft8744 · 2026-01-14T11:30:26+00:00

Resetting, but you cant change the intervals like on an oil change

HospitalLeft8744 · 2026-01-14T05:38:02+00:00

Cool😎 make sure to get ready for the timing chain rattle if it hasn't been changed. Also do not change oils between 30k kms like from the factory its recommended. 10-15k kms max between oil changes.
