A Look and Inspection: Helio's 2003 BMW M5 DINAN

[@trebm3]

looks like the headers pushed the O2 sensor location further back so a new hole was created to push the O2 sensor forward to fit into the underbody

[@944obscene]

That's what I gathered. The factory location looked too close to the heat shield. Wasn't aware the Dinan headers did that, and wonder if that changes the mounting points for the mid-pipes. It must.

[@paulsachs9983]

Yes you can see the bend in the undercarriage of the body would interfere with the factory o2 placement.

[@jeremyjova9518]

The heat sink in the back by the rear tail lights is a voltage regulator for the LED turn signals to prevent hyper-blink. the fronts will also have them screwed somewhere too.

[@lloydaom]

Could also be for the brake lights as they flashed on start up they them flash alternate sides every 15 seconds like the indicators do. The cold check for those bulbs needs coding out. I had it done on my 530d

[@john-okc450]

I have a 2003 M5 Dinan S2. My Dinan headers end in a 2-1 not 4-1 and are a little bit shorter than his. The section with the o2 bung - on mine the factory bung is exactly in the middle of that length of pipe, his pipe is about one inch shorter on the tail end. (My car produced april of 2003, Dinan s2 package installed when new, window sticker reflects parts & labor. I purchased in 2006 with 3k miles, now has 46k. No exhaust work ever needed) I just recently found your channel, great stuff. Thank You.

[@E39Source]

I found out later that these headers are not indeed Dinan, the sticker was added for different reasons (passing smog here in CA). Thank you for your input and support! The S2 package was around $50k, right? You've got a gem there.

[@john-okc450]

@@E39Source Around 30k for parts and around 10k in labor. ( I don't have the docs in front of me.) I drove a regular stock M5 once and couldn't believe the difference. WOW. (I had to loose the lightweight flywheel it made the car un-driveable, bucking back and forth at low RPM.) 1st gear is useless, I takeoff in 2nd always, and only need 2nd and 4th for non highway driving.

[@E39Source]

@@john-okc450 I have never driven a car with any more Dinan stuff than this M5. It was more difficult to drive for sure, but this is only because I am used to driving a more stock car. Bucking has never been an issue though! And I use all six gears haha

[@john-okc450]

@@E39Source The lightweight flywheel revs faster but drops revs just as fast, combine that with the re-gearing and I had to slip the clutch just to get past 2k rpm in 2nd gear to avoid the bucking. And If I left traction control on it would come "on and off, on and off, on and off" so fast and violent that it could give someone whiplash. It wasn't until I changed to stock flywheel that I could leave traction control on at all, It's still a problem 20% of the time.

[@E39Source]

@@john-okc450 People try so many different flywheels in the E39 M5-- but the stock one is the only one that people consistently like and, and that consistency lasts!

[@joey7253]

Those headlights and taillights... really really cheapens the car.

[@vladglebov7301]

Joseph C. Totally agree with the headlights but I don’t mind the tails to much since they are oem hella if I’m not mistaken. I probably wouldn’t tint mine tho

[@kzoomin]

That's a poor statement. FYI old faded amber U.S. spec lenses and broken adjusters perform terrible while looking cheap.. Retrofitted euro lenses with, bixenon projectors, replaced adjusters, ballast, and bulbs.. Exceptional lighting performance, while looking classy, and not cheap FACTS

[@kzoomin]

Smoked tail lights are not my preference though.

[@kzoomin]

Watched till the end. Ryan confirmed those are cheap Depo replicas. I thought they were retrofit oem Hellas at first.

Does this car have blacked trunk emblems? Ive been trying to get replacement Matte black "DINAN" and "M5" badges for some time, but all the ones I find are not in the correct size. Where'd he get them?

You can get the BMW Scanner 1.4 / PASoft from about anywhere. I may have from Amazon, actually.

[@ozdos8700]

Hi Ryan, sorry for the off-topic but just wondering if you've actually ever seen a 09/99 production E39 M5, as that is supposedly the first production month for the NA-spec cars. Or alternatively what is the oldest one you've seen, thank you.

[@E39Source]

I know I have worked on some 12/99s and maybe seen a 10/99? Not a 9/99 that I recall.

[@CM-1988]

Those wheels are Breyton Race GTR. I have them.

[@ibrahimomisore9202]

Hey Ryan, How was the leaking valve cover bolt fixed? I have this same problem on my ‘00.

[@E39Source]

It will depend on why it's leaking. If the bolt is damaged, replace the bolt. If the o-ring was compromised, replace the o-ring. Otherwise you may need to re-tap the threads in the cylinder head which would be significantly more work.

[@Juul380]

Is that Xenon or LED conversion headlights?

[@E39Source]

Standard xenons that the car came with from factory. I am not sure why somebody changed the lights.

[@bempie]

The wheels sure look like a BBS CY wheel. 2 piece. E39 spec wheel, had them myself.

[@jncast278]

Anyone out there had a problem with there taillight on a e39 2001 530i write me back installed a whole new taillight and still my reverse right white light dont light up only my left side does

[@E39Source]

The right tail lights on non-M5 E39s suffer from electrical contact corrosion due to the placement of the battery in that corner. You should get new wiring pins and a fresh connector on the harness, that will fix the trouble.

[@jncast278]

@@E39Source l)thanks for your quick reply could i get the part from autozone or would you recommend the dealer

[@E39Source]

@@jncast278 These will need to be dealer parts. Just explain you want to replace the electrical contacts and connector for the rear right tail light.

Why do you sound so annoyed because you saw wire connectors and different colored wires? Smh.. you sound like the techs at the BMW dealership I work at, that gets scared easily.

[@E39Source]

In the trunk? Because it's a total hack job of the factory system that could take dozens of hours to repair correctly. We get annoyed when things are half-assed.
