F31 335d remap - do I need to do this?

Smoke shouldn’t be an issue if you keep afr sensible.
Smoking is a bad remap/tune, assuming the goal is to not have it smoke.
As far as I know a dpf doesn’t absorb ‘smoke’, it collects particulates.
A dodgy dpf shouldn’t alter a smokey tune.
From a smoke point of view trust me I went back and forth. Eventually with no map the stock car also smoked. Suggesting a leak in the intake... replacing the DPF on the stock car stopped smoke not a trace for 500 miles, remap back on like I said since sept 2017 and maybe sometimes I might chuck out a puff here and there but nothing that can be seen in the rear view mirror. Previously with the cracked DPF you could see smoke every time even on the stock car.Smoking is a bad remap/tune, assuming the goal is to not have it smoke.

Welcome to be deleted if against the rules but that is what happened.
I'm sure there are many happy customers (I've not come across anything else overly negative) as with anything but the info I've had is not good.
As it was my car I wouldn’t say DMS where unhelpful. In the end of the day I took them a faulty car not their issue to resolve and defiantly not their problem to resolve issues with my car within the agreed remap price alone surely!

At the time we tried 3 different maps before I got the car returned to stock. My car was the first 335d they had that had a smoke issue. They were always super friendly and nice about it all.
I would happily use them again and recommend to anybody (in fact on those traffic light drags I tend to mention DMS each time when other drives ask me how my car is so quick)

You’d think issues would be baked into the price?If you remap you take away the slack and overhead engineered in, and so expose short comings.
I’d say it’s exactly their remit to identify and resolve issues that arise on a customers car after a remap that aren’t there before.
Or advise accordingly after a diagnostic run before remapping.
And even then, being expensive ‘experts’ you’d think they’d be able to fix anything their remaps exposed, given a car was fine before and not after... and knowing exactly what they changed, it *should* be easy.
I hate it when people make excuses for tuners who can’t figure out or spot operating issues on cars they’re remapping.
You either know the car inside and out to be tuning it in the first place, or you don’t.

Fair point when I had the issue I did try and seek advice from a couple of other garages to get an independent view it didn’t seem like an easy one to diagnose as none of them we committed to blaming the DPF without sending a camera into it etc etc. Others wanted to blame intake but lack of errors and perfect performance baffeled them. But yea would love to find somebody that does know this car inside and out however am struggling to find such a person that would know it to the ocd level I would need them to know it.

I agree! For me the first part of a reputable tuner's job is do make sure the standard car they're about to work on and modify is in good health before they start; if they don't do that how do they know they're not about to make a minor problem a more serious one by (for example) putting additional stress through a component which is already failing?If you remap you take away the slack and overhead engineered in, and so expose short comings.

If it was a £350 remap then perhaps not but the car was not smoking before you took it in and afterwards it was, que cera etc.
But for £900 I'd expect them to massage my ball bag while I cried .

I'm sure they were helpful but the point is bro you paid £1000 (nearly) for some inconvenience and a broken DPF

Hahahaha! Awesome you just gave me a really cool business idea! Remap with happy ending!!!
Exactly, £900 is solid gold service quality.
If they can’t figure out what is wrong with a car for that much money, as supposed ‘best in industry’ experts on that car, then they’re basically telling you they aren’t by being incompetent.
If you charge s
t loads you need to be shot hot.
Failure to do so makes you look silly.

A bit late to the conversation but...I had my F31 335dx (with M sport package) remapped by Viezu. I had used these guys before with two previous cars. Highly professional setup and respect what the customer wants - unlike DMS who were dreadful and way overpriced. Completely aware of the drive train capabilities and maximum allowed torque I specified they use the ACS remap figures of 360hp and 516lbs. I ended up with 365 & 520 (crank) so close enough. Yes they could have gone higher but i wanted to preserve my gearbox and transfer. I have also upgraded to ACS quad exhaust & springs, Bilstein dampers, front and rear brace struts, EBC yellow pads and drilled Brembo discs so it stops and turns perfectly. It is markedly quicker but has not been turned into an unruly and uncomfortable beast. As a back road drive it is a an absolute hoot, overtaking is effortless. I change the oil every 8k and the transmission oil will be done at 50k just to keep things sweet. I have zero regrets getting it done and would again. I love this car

Question do you drive it in comfort or leave it in Sport all the time? Gearbox?
No one has answered this - I guess nearly everybody leaves it in D 99% of thevtimd yet want a remap, Drive it in Sport mode it’s vastly quicker. Then use premium diesel
I see no need for a re-map on mine. Drive in comfort, and knock it left for sport, and also use manual for fun on up and down hills around here.
I would spend the money saved on decent diesel. BP Ultimate is best, then Shell V-Power. If I can’t get those, I use Shell Fuel Save, or BP regular diesel.
