Bump Any suggestions except for the digital chicken dance

As per the title I have tried on many occasions now and found a few problems that I thought would be the cause the latest being the door lock switch in the centre console was busted but seeing that it is a simple momentary make switch it should not be the cause. I notice that in one of the diagrams ...

Great thanks for those hints I will get in there and have a look around.

Rain Rain glorious rain but when I opened my glovebox, it was full of water. Not just wet but Full so that it spilled out over the already saturated carpet.Unaccustomed as I am to seeing water falling from the sky I was somewhat surprised. We got 6 inches in 24 hours but at my sister in laws place o...

The N62 doesn't have a fan in front of the radiator and that is where I have extra cooling for the engine oil and transmission oil so with 9" fans on each of those coolers there is no room there and towing a 24' van it needs all the cooling it can get. I like to have a manual override so that w...

It may be a hot climate only thing but from what I can see the E53 with the N62 (09/2003 to end of production) had just the electric fan behind the radiator and no engine driven fan. Being PWM as I thought they might be is fairly easy to get around with the use of diodes to isolate the system from s...

I am looking at putting an override switch on the cooling fan of my E53 N62 4.4L. Some I have found put a resistor across the temp sensor and fool the DME that the engine is overheating then the fan cuts in but I found that on the K series bikes it also leans out the mixture and makes the ECU think ...

SOLVED The large O-rings at the outer end were preventing the solenoids from going far enough in so that the oil was leaking out onto the front cover and not getting to the vanos units in sufficient pressure to operate them or hold the set position. The O-rings were the recommended size of 35mm x 4...

I have found some that are cheap and for a very good reason so steered well clear of them. The HID lights for the low beam are good but the high beam QI are yellow in comparison and have been considering the LED H1 bulb but they do make a lot of heat and would contribute to the already far too hot h...

Here I am again with this heap. It has to be a Friday car before a long weekend or it could just be a normal 21st century piece of junk! Hoonose, I opened the back of the lights to get at the park light and indicator to tap into them for lights on a bull bar I built and found a heap of crumbling pla...

I haven't had a look at Pelican as yet but they don't seem to have much info on the N62 engines but I will have a look.

I changed the VANOS units put new solenoids in and it's still the same. Little bit noisy in the top end (cams etc.) and when it comes back to an idle from above about 2600rpm the rattle is very distinct for about 1-2 seconds. Fault readout says "VANOS actuator exhaust bank 1". One question...

Starting a "what oil do you use" thread can make for a long thread.
Firstly what engine does the heap run.
I recommend a major brand fully synthetic and choice of viscosity by the recommendations of the chart in the owners manual. Brand can be a matter of what is convenient for you.

Yeah I replaced the sensors. The more I think about it the more I come back to the solenoids being the problem. I think that because of the heat related problems these engines have from running at 105°C and seals, O-rings etc. going hard then the solenoids were sitting out of the engine for quite so...

This X5 N62 has a strange rattle in the top end. My iSoft thingy says Exhaust Camshaft control bank 1 and sometimes Inlet Camshaft control bank 2. When I start it, it is noisy but nothing very definitive until it warms up then all is quiet and smooth until I rev it past about 2800rpm and then as the...
