    MAF issue? (e39)

    As an update to this - the issue is now resolved. I managed to find a pair of new Bosch MAFs for a reasonable price. Whilst I was waiting for them to arrive I removed the plenums and checked all gaskets / seals and vac lines - all looked like they were in order. Fitted the new MAFs, reset adaptation and the car now appears happy. Shedloads more lower and mid-range torque as well as the top end power - no codes showing and the lambda integrator for bank two now hovers around 1 (same as bank 1) where as it was previously maxed at 1.25 and throwing the code. Upon inspecting the old MAFs, they both had different part numbers, one I think being a VAG part. Thanks for all the advice and suggestions.

    MAF issue? (e39)

    Spent a few hours on the car this-afternoon trying to identify the issue by process of elimination. I'm basically trying to avoid loading the parts cannon and hoping for the best . So, the current issue; Code; 145 Lambdaregler 2 (the code appears again whilst idling after being cleared). Lack of power unless the MAFs are unplugged. Observations; Missing gasket/seal between the MAF and intake pipe on the passenger side (assuming bank 2) - however there doesn't seem to be any air getting in. Things attempted; Switched over the MAF sensors - no difference. Switched over the missing seal to the other MAF sensor - no difference. Unplugged both MAFs - I get errors for no MAFs and temp sensor, original 145 code does not appear whilst they are unplugged. Switched over pre-cat lambda sensors - no difference, same 145 code. As the code related to the lambda on bank 2, I thought it may have been a defective sensor, but as I switched these over and got the same error - I have ruled out the lambda itself and assume this is being triggered because of another condition. I'm not sure if I'm leading myself on a wild goose chase or over-complicating things, when it could just be a bad MAF (or both) - thankfully Jamie may have a spare set we can try, but thinking it could be caused by an air / vac leak, a bad injector, or a wiring issue. My next plan is to try the different MAFs, then remove the inlet to inspect vac lines. For the time being - I will add some screenshots below, maybe something obviously not right; Code; Analogue values (at idle); Run Unrest (at idle);

    MAF issue? (e39)

    Evening, Wondering if anyone has experienced the same potential MAF issues that I "think" I have at the moment. Today I changed the spark plugs and air-filters on the M5, I drove the car home - it felt the same as it has since I have owned it. When I got home I plugged the car into INPA for the first time to check any codes, thankfully there weren't any. Whilst I was on INPA I saw the option for "delete adaption values" - because I'm trigger happy. Went out for a drive shortly after and found the car was underperforming - massively. Around 3500 rpm where the car usually starts to sing, it flatlined in terms of power. I could still get to the redline but felt like I had half the power. I read a few threads regarding throttle adaptation (leaving the key on pos II for 30 seconds.etc), this didn't make any difference. I decided to unplug both MAF sensors to see how the car ran on a default air/fuel condition, oh my word - the car flew. I don't think it was placebo, but the car felt quicker than it ever has under my ownership. I drove the car for around 5 miles like this, it performed flawlessly. Upon plugging both MAFs back in, the car lacked power again, combined with the engine management light. I cleared the codes, but the car was still underperforming. To me - it sounds fairly conclusive the MAFs are bad (car is on 145k with no record of the MAFs being changed), but before I shoot from the hip and buy a pair, is there anything else that may cause this? Thanks.

    Bargain! Wish I had seen this last month
  9. Pair of front arms removed from my 2002 530d - I believe these will fit all 6 cylinder models (not V8). Poly bushed around 30,000 miles ago - ball joints are all good. Asking £60 delivered, thanks.

    E39, What annoys you.

    Every e39 out there would still be worth £10k Sent from my BBF100-1 using Tapatalk
  11. I have available a full manual conversion for a 525d / 530d. This is not suitable for petrol models. The kit comprises of; GS5-39DZ 5-Speed gearbox, oil replaced around 15,000 miles ago with Redline MTL (receipt for oils included). Engine - Clutch dirt plate / cover. Dual Mass Flywheel - Good condition (no knocks or excessive play). LUK Clutch & Release bearing - replaced around 15,000 miles ago (with receipt). Pedal box. Clutch slave & master cylinders. Reverse light switch wiring to ECU box. Pipework for master to slave cylinder with grommet. Brake fluid feed pipe and grommet from reservoir. Propshaft coupling / guibo, replaced around 15,000 miles ago (with receipt) Gearbox mounts. Shift lever, linkages and knob (no gaiter included as I needed this for my other e39), I replaced linkage bushings a few years ago, which are nice and tight. Propshaft. Rear differential - Oil replaced at the same time gearbox oil was (Fuchs). Rear driveshafts. All gearbox / engine / flywheel / clutch bolts. Gearbox is missing a small amount of the rear bracket - has been like this since I owned the car. Was fine when I found it however I just used a large flat washer to spread the load over the rest of the mount. Collection only from Liverpool, asking £500. Thanks.

    e39 HSD Monopro Coilovers

    Purchased August 2016 at the cost of £787 - covered around 25,000 miles. https://www.hsdcoilovers.com/hsd-monopro/ Springs look rough - the paint / powercoat has flaked off however the springs are fine (may benefit with a paint before fitting). Threads are near perfect - they were coated with copper grease when fitted. Shocks are good, no knocks or bangs - front nearside was replaced under warranty in October 2016. Adjusters, top-mounts and bushes are good. Spring rates are; 8k rear, 10k front. They seemed ideal on my 530d, Comfortable enough for normal driving and precise when needed. After £350 collected, can post at extra cost. Many thanks.

    E39 M5 headlight adjusters - MOT failure

    Shame they aren't the bake openable lights - I would have been happy doing this for you. I actually have a spare set of adjusters too! Sent from my BBF100-1 using Tapatalk

    Andy's E39 M5

    This was on ebay a couple of months before mine and was probably one of the main influences for me actually buying one. It looks mega, great combo. Look forward to seeing where this goes.
