E46 takes long to warm up

my E46 is BMW 325I 2003, takes about 25 min. to get warmed up !! is that normal ?!! and if not, what it could be ?

Warmed up to what temp? If its to the middleof the gauge without driving then yeah thats normal. Maybe some more details?

Yes till the middle, I have to, because if I moved before warming up well once I accelerate it stop totally.
I was have Toyota and mitsubishi but never took that much.
Even a friend was owning BMWx5 wondering

Search for the hidden obc menu on here. Figure out your coolant temp. Should be in the 90's. Also buy a code reader like pa soft. Your thermostat is likely bad.

Yeah thermostat is probably bad. Do you get a coolant light? Does your heater work intermittently?

With a stuck open thermostat, heater will work fine but it will take a while to warm up and the coolant light will not come on unless something else is bad. (With the car being as old as it is, there is a real possibility that the rest of the cooling system is bad anyway.)

True, but when my thermostat was jammed open, my heater worked at a sub par level

That makes sense as well.

Well I will do, I don't know as much s u but u just changed the radiator, not sure ic this info. Is important or not but I found its better to say.
Thank u so much..if it solved I will come and tell

For what reason did you change your radiator? It's a good thing but I ask because I'm wondering if you had other issues. The entire cooling system should actually be replaced. Considering that you need a new thermostat, it may be a good time to do everything.

I do got heating issue before and cost me to change upper chamber of the engine. .there was leaking in the radiator so I changed it.
What else u advice me to do?

Here you go. It also has links within for thee maintenance advice.

So changing the whole heating system will help? Or just a guess

It's actually called the cooling system. And the main thing that will help you is thermostat replacement but the entire system is likely at the end of its lifespan and so if you can afford it, go for a full replacement to ensure that don't have problems anytime soon.
