Today I un-bricked my MK3 nav after I didn't follow directions the first time, then put in a map disc so it now actually functions. Also replaced burnt out drivers footwell light, and two door courtesy lamps, and replaced a few broken trim clips for door seals. Sometimes it's the little things that make the difference!

I installed my aFe intake. I am pretty impressed with the quality -- it used all the factory airbox clips and everything fit perfectly. I dont think it released any h-pees, but it certainly gives a bit of a nice growl at WOT. Doesnt seem like it will sound drone-y while towing either.

Wired up my (older/hardwired) Prodigy brake controller. Thursday is the first camper tow. Spent significant parts of the last 3 days putting a new oil pump in wife's E83 (N52 serpentine belt ingestion). My back needs a couple recovery days!

This was new info to me shortly after buying our 530xi E61 a few months ago. Scared the piss out of me, but so glad it prompted me to inspect things. Belt was getting chewed up on the inside. Turned out a shop or PO had installed a junkyard AC compressor that must have come from a car that had been hit pretty good in the front. The pulley was not true. I don't know how long that belt would have lasted (I had already ordered a replacement, along with plugs, coils, VC gasket, etc, etc) but knowing about the ingestion problem made me glad I had checked it out. New AC compressor pulley and it's back good to go now. But... things could have gone south in a hurry.

I might be on to a cause (and therefore a solution...)

I happened to be flicking through the vehicle manual on the weekend whilst looking for a way to change the DSP sound preset (got the original nav) and came across an index reference to EBV....

The manual states that it is a booster for the braking force to the rear wheels to assist the vehicle stopping straight particularly at speed with extra pressure. Been doing some digging and it apparently relates to an electrical harness/contact on the right rear wheel being rusty somewhere...

Have to replace a plastic retaining clip on the rear axle for the brake lines so as soon as it comes in am going to see what I can find....

Found this in one the BMW training manuals (on brakes...)

Electronic Brake Proportioning (EBV)

The Electronic Distribution of the braking force (EBV). Will adjust the braking force to the rear wheels based on the vehicle’s loading to maximize the braking force at all wheels.

The control module monitors the wheel speed sensor inputs, when the brakes are applied, to determine vehicle loading. The control module compares the rate at which the front and rear axles are slowing down.

If the rear axle is slowing at a rate similar to the front it indicates that the vehicle is loaded and more braking force can be applied to the rear calipers to stop the vehicle.

If the decel rate of the rear wheels is far less than the front, it indicates a lightly loaded vehicle. At this point, if the same braking force were applied to the front and rear axles, the vehicle would become unstable.

If this difference exceeds the threshold values programmed in the control module, EBV is activated. The control module will cycle the inlet valves to the rear brakes to regulate the braking force.


Sounds like it uses the wheel speed sensors and not any other sensor...

That maybe explains why people replacing yaw sensors not finding any solution...

Hmm.... there is an electrical connector mounted up near the rear strut....I'm thinking that as I have the red TPMS light on and this code that I might replace the wheel speed sensors to start with....

Other than those, there's only the yaw sensor or the control module itself so might as well start with the cheap stuff first

Yes.... yes they can.... all this was crammed in the pickup tube. My oil pressure measured only marginally weak, but I had battled inconsistent vanos operation and I had a rattley noise on startup that I eventually figured out was the oil pump. Take good care of your N52 belt system. The most common cause of failure seems to be from a leaking oil cooler gasket or OFHG. Oil gets on the belt and lets it wander off the pulley.
