    Hi Matt yes it does sound similar. The pulsing is very discreet though, very short sudden and rapid with about 2 sec break in between, but still noticeable. This goes with the noise I can hear from underneath the car/transmission area. It does sound pretty similar to your problem. 

    I did run codes last night and I have quite a few:

    8B Activation, map cooling
    23 Additive mixture adaptation (idle) cylinder 5-8, control limit reached
    1B Additive mixture adaptation (idle) cylinder 1-4, control limit reached
    12 Oxygen-sensor ageing before cat. conv. cyl 5-8
    73 Hot film mass air flow sensor (I had to disconnect the MAF the other day and start the car so this may have appeared because of that, will need to see if it appears again)
    0A Oxygen sensor before catalytic converter cylinder 1-4
    3E Misfiring, sum, relevant to exhaust gas
    39 Misfire cyl. 8

    The oxygen sensor ageing, activation map cooling, additive mixture adaptation and misfiring sum relevant to exhaust gas have all been there for a while as I have cleared them a couple times over. The misfire on cyl. 8 is fairly new.

    I did replace a coil on cyl 4 a couple months ago but it was clearly dead, this doesn't feel like it's running on 7 cylinders like it was 2 months ago.

    Unfortunately not, problem still there while in tiptronic mode. M

    It's actually been like this since I got it, a few years ago. But it sounds like its got worse in recent weeks, ever since I moved house and now cruise the motorway everyday to and from work - where I stay in that 1-2k RPM cruising speed where the problem occurs.

    I need to sell this car, but im assuming this is going to devalue it big time, not like its really worth much more than the repair cost itself.

    Wondering if someone can recommend a shop preferably out West, but the Shore also, to get my 1997 e39 540i Auto Trans fluid changed. Also how much does this usually cost?

    Getting what appears to be a grinding noise and pulsing of RPM's around the 1.5k-2krpm mark while holding the same steady speed going slightly uphill. No codes are thrown but I suspect it could be the torque converter having some trouble. At around 190km It could be a good idea to look at changing the fluid anyway.

    No not Vanos. Its 1997 model. Hopefully getting it scanned with a good scanner tommorow. In the meantime I just got home and ran my scanner thru.

    70 Camshaft Position Sensor

    4b Misfiring with cylinder cutout, total

    3e misfiring, sum relevant to exhaust gas

    Activation Map Cooling (picking this is separate as I often get the check coolant level msg on my dash)

    33 minutes ago, Michael. said:

    Boxer WRX sound from a V8 usually indicates it's running like a V4 or similar. 

    1UZ V8 Toyota engines I deal with do that when one of the two coil packs fail (each does 4 cylinders)

    However in your case it sounds like something else has failed that controls half the cylinder firing, likey the DME

    Yours has 8 individual coil packs and igniters on each cylinder so its unlikely those are the issue (they just don't fail all at once!)

    Another common problem with DME is when your traction control lights, abs etc come on by themselves right? This used to happen every so often a while back, could also explain the sudden power loss/traction light coming on as I described above. I really hope its not DME, from what I've read, that's bloody expensive.

    Had a problem arise this morning. Car feels like its running on less than 8 cylinders, feels like it’s just about to run out of gas, sounds like a Subaru boxer engine would be the best way to describe it. At idle it feels fairly normal though. I also noticed that when I went around two roundabouts this morning (so fairly hard turning) the drive belt started squeeling and applying resistance to my turn, exactly how when your running low on steering fluid and you try and turn the wheels hard right and left and it will squeak.

     

    I’ve had the following symptoms for the past while:

     

    • Rough idle every now and then, usually on cold mornings, hasn’t happened much recently though.

    • Some weird pulsating when cruising around 1900-2000rpm, you can hear a soft grinding/gurgling like noise and a slight pulsing, almost like it cuts out for a split second every 2 seconds when held at this rev range. Feels like a fuel issue?

    • Car stalls when come to complete stop or on a hard turn at very slow speed. This has only happened a handful of times so it’s not regular.

    • Lately the car will lose all power for about a second and then kick straight back in, usually upon acceleration, sometimes the traction control light will switch on after this so it’s like someone hit the traction control button mid-acceleration.

     

    I realise I probably need to take this in but im at work for the whole day so thought I would test my luck on the forums first, it would be great to tackle this myself this weekend. I'm hoping it's maybe just a bad coil or something like, in which I can test tonight when I get home to rule that out.
