    Hi all,

    Does anyone know anywhere in Auckland that can diagnose if my ABS Module is at fault? I have had it scanned, which came up with a wheel speed sensor, replaced that sensor but still same issue. I've had some issues using Multimeter to test sensors from connector. 

    Would be good to have someone that can check module directly before I look at paying to have module repaired ($450) or find a new replacement overseas and programmed for car.

    Could be the idle Air Control Valve (possibly in conjunction with other things), at that mileage it could probably use a clean.

    Cheers for the suggestion. I put my cheap scanner on it and found some lean codes. Had a Google and checked the intake pipes. Found the intake boot closest to engine was cracked so replaced that and the power and launching is perfect now.

    I just noticed this morning that the cold idle is still a little rough so might be another thing.

    Sounds similar to my 523i before i did the vanos on it. Need to get it scanned first though, otherwise its just throwing money at a problem hoping it sticks.

    Mine was a real dog when cold, surging and was damn near impossible to cruise smoothly at low-mid throttle (would surge and jerk until i let off or gave it more gas). Made it interesting leaving my old parking building when cold.

    Yeah that's one thing I've heard different to other peoples problems. Unless you notice it while stationary and cold it isn't really that noticeable when you're driving nicely. Only with.. spirited driving. But hey maybe they seals aren't quite gone yet. I'll try find someone to scan it.

    Hey guys,

    I have been reading up about VANOS seals and the like but I'm still not 100% convinced if this is issue.


    I've only owned the car for about a month. I've noticed when putting my foot flat on accelerator from a stand still the car slowly sets off then surges through the rev range. If I kick it down to 1st gear while rolling it seems to pull much better. This surging also happens mid range when full throttle while moving too.


    I've also noticed a small rough idle when the cars cold, this goes away completely once the car has warmed up.


    Sometimes the car will launch perfect off the line like a bullet and give me a surprise so I can't figure out why sometimes it perfectly fine


    The problem is pretty unnoticeable while doing light city driving why I didn't notice it in test drive :P It does seem to be lacking low down power sometimes and changing down gears unnecessarily.


    Any advice will be appreciated!

    Car is a 2001 530i Motorsport


    Cheers
