What did you do to your E39 today ?

Today I have had a quick spanner on the saloon to extract the alternator. Ever since I have owned it it’s whistled, like the car is supercharged. Confirmed with a stethoscope on it that it was the culprit for the noise. So, it was a nice afternoon so set about extracting it.

 

Usual knuckle grazing affair but came out just fine. Got a local place that rebuilds them for reasonable money so think I will go that route though have seen enthusiasm on here for some cheap eBay ones. Hmm... 

 

Ducting up the alternator was free of leaves but under the plastic cover on the rear of the alternator itself, fed by the duct, was full of leaves and (weirdly) cigarette butts!

I know the whistle that you're referring to here Jim, and I seem to recall it being present before I even bought the car.

 

Very weird too about the collection of fag butts at the rear of the alternator. V42 definitely lived at two smoke free households prior to yourself. :huh:

Ask this as a question on its own otherwise it'll get lost in here

Had a chat with the local stealers. Turns out they are really helpful, and v interested in the beast.

Anyway, it turns out that the new fuel pump I fitted cured said starvation issue & she fired up first time.

There was v low pressure from the pump & it wasn’t enough to overcome the nrv fitted to maintain rail pressure!

It fired up so fast I thought she’s breathing fire again! Grins!!

Next job is a gearbox refill. Local firm will do it, followed by the water pump and associated pipe work and facelift lights.

It wasn't very loud certainly but I noticed it right away after getting the car and wanted to try and suss it out because I know these cars idle extremely quiet and smooth but it was the sound that I ended up tuning into every time I started it so... it'd been on my list to tackle for a while, and once the weather improved I was ready to have a go :) At least it's another small detail attended to. 

 

And strange about the cigarette buts! There was a good few in there.. no idea what caused them to get hoovered up the cooling duct!

Super; update when you can

 

My local starter motor and alternator specialists have quoted me £120 for a fully refurbed alternator and with 18 months warranty! Think I'll sort one next week

 

Picked up the alternator today and it looks great honestly.. every nut and bolt looks like new and they even thoughtfully kept the original BMW stickers on it so it just looks like new / original piece. Not unwrapped it yet but will try get a picture later.

 

Only car geeks could get excited about a refurbished alternator, huh? :D:D

Are you sure it’s the alternator that’s making the noise and not the water pump, A/C compressor or other pulleys?

 

Kind of agree with this @chicaneuk - alternators usually grumble, not whistle.

 

How olds your water pump, what about the bearings and viscous fan etc?

 

When you start the car; is the whistle there from the off? If so, what about spraying a touch of WD40 onto the various pulleys and see if if goes after that?

Yeah need to tear it all out and have another look / listen. The weird thing is if I stick a stethoscope on the alternator it seems like the noise is originating from there but.. I guess it’s very possible the noise has just transferred up from somewhere else. 

 

Too annoyed to go back and work on it again today.. maybe Sunday or something. 

 

Definitely is louder on the alternator side of the engine so sure it’s from around there.. could just be an idler pulley I suppose?!

Could be, like I said, spray it with WD40 and if it goes quiet, hey presto ;)

Fitted my Piano Black trim yesterday! Looks so much better with the Storm aluminium gear knob and handbrake handle - the different finish between the Sport aluminium effect trim and the other parts was starting to make my teeth itch.

 

Car is also going in for new water pump tomorrow. Can drive it this summer with confidence!

Fitted this morning as I have a day off. Still whistles exactly the same as before if it a bit worse. Not amused. 

I may have said this before, but way back before I bought V42 and became familiar with E39s, my neighbour had one. It was a T reg, a 528 I think, in dark green and with what I now know are Style 32 wheels.

 

Anyhow, I'm certain that car had the same whistle that I/we experienced/experience with V42. Apart from maybe being an annoyance, it whistled for the nearly 10 years that I ran the car, so if it was some type of fault you may have expected whatever it is to fail within that time. Just a thought...

Cheers Keith... I appreciate it's probably not a big problem and I could probably run the car for years more without it turning into an issue but.. honestly it's bugging the hell out of me :) I'm determined to work out why it does it.

Got all the bits together for tomorrow's ramps session and painted the brake disc hats Hammerite silver to stop future rusting ;)

Found the cause of my annoying whistle. It seems to be the belt tensioner that sits between the water pump and alternator.. no obvious resistance and spins pretty freely when you spin the pulley but get it up to any kind of speed and it's surprisingly loud. Video below but doesn't capture it fully in terms of volume. I removed the tensioner (although it does feel extremely stiff!) so I think I might just replace the tensioner completely rather than just the pulley :)

I notice also from RealOEM and reading around it was superseded with a more elaborate hydraulic tensioner but.. think I will stick with the original design for now!

Oh; rear drop links and prop duffnut being changed too... Think I might leave the brakes to another session when they can be done in one go along with the lines, but will see how things go tomorrow

 

The cars been given a good wash and Autoglym Aqua Wax though in readiness; it's nice to work on a clean car ;)

Basic oil filter and oil change done - who know it would be so simple.

 

Weirdly I've had 2 people knock on my door in the past few weeks asking if my E39 is for sale :rolleyes:

Fixed a weird and completely random ABS issue (both rear sensors were properly caked with crap), so a quick wheel off jobby, removed the sensors, cleaned them with brake cleaner and a cloth, reseated them, wheels back on, drove the car, no more warning lights ;)

Haha indeed, although the first seemed like a genuine E39 enthusiast and knew a fair bit about the cars! Either way the cars on the drive with CCTV covering it, may also invest in one of those steering wheel locks or a GPS tracker :ph34r: Any recommendations on car security?!

Funnily enough, I bought a Stoplock Pro this week. Not alarm fitted to ex Jap E39s

Front wheels off, ABS sensors removes, cleaned (absolutely caked in crap), reseated, wheels back on, test drive to make sure no lights... 

 

Will probably order all 4 just for peace of mind

I looked at it - again. Still stripped down, still waiting for the thermostat to arrive... the sodding radiator (that I decided the car needed) managed to arrive before it!

 

not all bad I suppose, I’ve been driving my E34 all week. Miss the speed of the 530i though...

New tensioner came in the post. As expected... totally silent and actually doesn't spin as freely.. in that the pulley has a little resistance. But as I say, it's absolutely silent. Hopefully get it on the car this weekend! :)
