7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

E65 no heat only cold air

just bought an E65 and the first thing is that it only blows cold air no heating at all and i turned up all the buttons to make sure . All the buttons work but no heat and its winter.
Also i realise that the airfilter box is missing and they put on some kind of round looking filter that is not even in a box it looks like some kind of sports filter. please please help.

Look for codes related to the auxiliary water pump (it's a little electric pump in the engine bay along the driver's side wheelwell on a LHD/USA model...not sure which side on a RHD model) or water valves.

I had a similar problem with my e39 and did the following

1. Check the coolant level
2. Make sure fuses for the heater are still good.
3. Check the heater control valve to make sure coolant is passing through it.
I replaced the heater control valve and that did it for me. Warm and toasty now.

yes i did check and the heater was never working. Actually i am in the process of selling my old car but once thats done i will have alot of time to explore all the issues and run checks. also is -5 outside on most days now so am not up for it, but once i sell my old car it will be hard work to get mr e65 heating, also the airfilter box is missing and replaced with a screw on sport filter do u think this could be affecting the heat.

The airfilter box has nothing to do with the heat. If your blower is working, I agree with Keif that the source is either your auxillary pump for the heater control valve, or the hcv itself.

This part is not cheap and I was hesitant to buy a new one. So I bought a used one from ebay for half the price. It fixed it for me. You'll have to determine whether or new or used works for you. Mine came from a car that had 78k, so I figured it had another few thousand miles before it goes out again.

The heater control valve is located to the right of the engine (if you're looking at the engine from the front). It will have two round cylinders at the top. Do a google search for heater control valve and you'll see exactly what it looks like.

Hope this helps.

It's very, very unlikely. If you have head gaskets problems, you have a bigger issue. However, diagnosing a heater problem is way less expensive and less time consuming than dealing with any head gasket issues.

Do the following first and it will likely fix your heating problem.

1. Check the coolant level. If low, refill.
2. Make sure fuses for the heater are still good. Fuse boxes are typically in the glove compartment as well as the trunk.
3. Check the heater control valve to make sure coolant is passing through it.

also in iDrive in climate control screen make sure those futures when you have option to choose more blue (cool) or red (warm) both for drivers and pass sides, if in your car those future set at blue colored this is a reason why you getting cold air, so turn them to red, hope you'll understand what I'm talking about, sorry my English is limited to make it clear what i mean.

Flushing the system is not necessary, and you don't have to remove the hoses.

Just feel the hose(s) that go behind the heater control valve and into the heater core. These will be hoses that go towards the rear of the engine bay, not the front hoses. The front hoses will feel warm, but the hose that comes out of the valve and towards the back of the engine will feel cold, indicating that the warm coolant is not passing through the valve.

Well just felt the hoses and they are all hot . The front hoses are too hot to hold but the one going to the heater core is not so hot as I can hold it for atleast 1 minute. By the way should i take it out and clean it or they can't be serviced. Anyway all hoses are hot but how can u tell if its hot coolant or the engine that hots the hoses, but am sure the front hose that goes into the control valve is hot from coolant as I can bearly touch it but the other side I can hold it for atleast one minute before it burns me.

If one side of the heater control valve is hot and the other is cold with the heat turned all the way up, even after revving the engine a little, then you've likely found the culprit.

Not really one side cold and the other hot. Its one side is very hot that I can't touch it and the other is hot but not so much as I can hold it 4 a while.

I have to replace the heater control valve. I took it out and apart and realise that one of the pump rubber was completely missing, i believe it rotted off and the other one had a big hole in it so there is no way the pump could pump the coolant into the heater core.

Did you replace the auxiliary water pump yet? Do you get heat when you drive ?

Have not replaced the pump yet , I did add the #1 fuse just in case still no heat . None when driven either. Still waiting on more info first . I am not sure about the pump because as soon as the hose gets warmer at the pump it gets warmer at the value outlets at the two water valued outlets . Hot at pump its hot at value outlets same time . Outlet hose gets so hot you cant hold your hand on it long . Scan also showed pump on and back off as well . Still not sure . I am thinking hotair flap is broke or stuck , or either a sensor is bad and telling it not to open .
