X Plate e39 530i Sport Auto 120k Miles.
MOT failed, two brake pipes needed from the front to back on both sides, not too bad on a 15year old car tbh, nothing else which was a pleasant surprise.
Given my recent issues with power loss and EML / Check engine light / Traction control lights coming on individually and in unison, I decided to make the trek to an old trusted garage who I've not used for a few years (but who looked after my e36's, e38 and last e39 back in the day, only stopped using them due to moving out of the area) and asked them to look into it for me.
It had the VANOS seals replaced 15k miles ago so I don't think its that.....
They reported no codes bar steering angle sensor which they sorted but said no codes stored or warning lights were lit for the engine,thankfully though all three lights lit up when I picked it up - much to their embarrassment I think! - and it sounded almost as if it had no air filter when you revved it, a very throaty induction sound and slow to rev, so at least they now know what its doing even though nothing is still showing up when its read.
So, its stayed overnight and I have a Mk1 Focus loan car - which makes my 530 at its most unresponsive seem somewhat powerful! - instead of yesterdays Qashqai which I was surprised to find I liked!
Hoping they finally get to the issue with my e39 but I'm not confident tbh, this will be the third place I've tried for a resolution (along with changing various sensors myself) yet still it seems randomly down on power and hesitant, the weird thing is when its behaving it runs - and performs - beautifully, its not a continual fault.
I can see it getting a valet and going on A/T with its new MOT very shortly if this is not resolved, shame, I love the car but am getting thoroughly sick of it running like a dog, my 270k mile 528i ownership was a much more enjoyable experience.
