Singapore grey 2016 M5
Discussion
Some of you may have seen my previous thread about my suzuka grey B8 RS4 avant.
https://www.pistonheads.com/gassing/topic.asp?h=0&...
My time with that car has come to an end and I've replaced it with a 2016 M5 in singapore grey. The M5 was on 25500 miles when I bought it and is pretty decently spec'd with bang and olufsen, upgraded merino leather in silverstone, heated rear seats and many other bits.
Here are a couple of pictures from just before I collected it:
The car was advertised as having a stage 1 remap, it drives lovely and felt pretty quick.
A quick snap from the journey home:
The car had a few fairly naff bits IMO stuck onto it, it had carbon sideskirts front splitter and wing mirror caps. The mirror caps were stick on jobbys and were a bit sun damaged so I whipped them off, the front splitter looked OK but was cheap carbon effect so I've removed that and the ground clearance is much better now and the side skirts were actually decent quality but I'm just not sure I liked them.
After removing all the add ons:
Oh it also had a competition badge on the back that I've removed as it isn't a comp pack car.

All was going relatively smoothly and I was enjoying the cars mix of luxury and smoothness with the brutal pace and tail happy nature of the drive when you're pressing on a bit.... Then I found that the rear passenger foot well was a bit wet. I did some research and found out that the vapour barriers on the rear doors were prone to having the butyl tape failing and could let water in!
I removed both rear doors and sealed them back up where the barriers had indeed peeled away in the bottom corners causing water to leak in slightly.
I assumed this meant it was all good and continued enjoying the car for a little while... However when I next checked the carpet I found it to be wet again, I proved this wasn't from the vapour barriers and did some research which pointed to a failure of the 'yellow grommet'. This is a grommet that's fitted in the bulk head to cap off where the steering column would go on a LHD car... It's frankly one of the s
ttest solutions to this issue that I have seen! It's basically a push in plastic cap with a rubber seal to prevent water ingress, the windscreen drain soaks away to the area where this is and if the little drain for that blocks it basically makes a little pond that over many years ends up leaking in through the grommet to the front passenger foot well and then running under the carpet to the rear passenger one!
I hadn't heard of this but it's seemingly common on all F10 series cars and a quick youtube search shows many cases and the way to fix it. The unfortunate thing being that the M5 having such a big engine means you can't fix It the same way as on smaller engined variants. I basically ended up ordering a new seal and replacing it all from inside the car, I've managed to unblock the drain that causes water to build up and also replace the seal.
As you can see from the picture there's a water mark and the lip seal had perished and crumbled away allowing it to leak in, it was a real pig to replace but once I was happy it was in correctly I also OTT sealed the grommet up to hopefully prevent this being an issue going forward!
Now it's all sealed I have begun the process of drying it out, I bought. Wet vac at screwifx and hoovered up any water I could and then hoovered the carpet to suck out as much as I could and now I just keep fitting little dehumidifier bags which seem to be doing a good job as its now all dry and I'm just getting the remaining humidity out!

Hopefully on to some more positive points now and actually enjoying the car! I checked a couple of things on dragy and the car was performing like standard, this caused me a dilemma... It was supposed to be remapped but was behaving like it wasn't, was the car just on a really bad stage 1 map? Was this map safe? Had the car just been returned to standard? So I thought the best course of action would probably be to have the car remapped by someone trustworthy so that I know whag I'm dealing with. I did some research and decided to either get an Evolve remap or a Velocity performance one, in the end I settled on the velocity performance remap which was a VT700 file which should give around 700hp and 590lbft... The car now behaves like a tuned car and actually drives a lot nicer at low / maneuvering speeds as I think the throttle map is just a lot better than the one that was on the car!
I've also now managed to fit my number plate and also a cheeky little pistonheads smiley.
Hopefully I can get some confidence that the car will stay dry and I can start to enjoy it!
I have already noticed the car is about the most tail happy thing that I've ever driven.. The standard traction control is very scared and interrupts all the time! On M dynamic mode (MDM) the traction control is so much better but you do have to be careful as I am pretty sure it will give you enough rope to hang yourself!
Also remembered that I also removed these vinyls

That looks a fantastic car; sods law re the fabled yellow grommet, but you've got it sorted 
It was a sod to sort on my FiL's F10 530D; really struggled to get my hands down to it but got there in the end...
I love the alloys on your M5; they'd look superb in silver against the cars paintwork...

Having driven a few standard and mapped M5s, I feels that is an small understatement 
I love an M car, my brother chasing me up the autobahn last year in his was a highlight of my trip. They're big old cars but for those kind of drives it was great. Yours looks much better for the tat being removed too.
Cheers for the replies chaps, I am falling pretty deeply in love with the car despite its moistness! The garage are paying me for the bits to fix it etc. And I suspect they genuinely didn't know as it was stored inside and I didn't spot it on my look around... To be fair I don't think of modern ish cars leaking though!
You're right I did massively understate the speed with it being absolutely ballistic in reality especially now it's running the velocity tuning map, they suggest 700hp ish and 590lbft which feels entirely believable... It's basically as quick as my old E63 was.
The gearbox is brilliant when rolling, it feels a bit dim witted when setting off and maneuvering. The engine sounds good but it's very quiet inside the car at least... The way it gathers speed in 3rd and 4th is insane but fun I can see myself tinkering with it in the future but for now I just need to sort apple carplay fitment i think, as good as the idrive is it's not as east as carplay. If anyone has any recommendations they would be greatly received :-)
Need to decide whether to replace these as well

You have had some nice cars!
Curious plates though!
Cheers, if you mean the shape of these ones it's because I swapped my plate on and then realised I didn't have any normal ones in the garage so had to use these ones as they were all I've got... I've got some normal ones in the post Curious plates though!
Stunning car, this is definitely one car I’d love to buy in the future.
For CarPlay, you probably have NBT Evo ID4. This can be flashed to ID6 with CarPlay but it can crash on long journeys which becomes annoying.
Alternatively, you can buy a NBTevo id5 unit and flash that to id6 and get CarPlay.
Parts are between £250-£350 and about £150 to code. Easily done in a few hours.

Thanks for the info, I just have the NBT and not evo so it's looking like a separate MMI box or screen replacement I guess? The replacement EVO stuff looks to be fairly expensive as an upgrade from what I've seen For CarPlay, you probably have NBT Evo ID4.
