Any experience of the ups and downs ?
Any experience of the ups and downs ?
Some cars can have their autobox remapped, might be worth looking at.It’s a BMW 520d auto tourer 47k 12 plate, I don’t need more speed but I would like it to be more responsive from the get go, I think it starts in 2nd gear and as you give it more gas it drops down to first and lunges forward, it’s very annoying.
OP’s car has an auto gearbox, so no worries about DMFs.
He has an issue with the gearbox driving away in second and then occasionally dropping to first gear.
I’d try to find a local remapping centre, not a man with a ban and laptop, who can remap the gearbox (if possible) and maybe do a deal on engine and gearbox remap.
Is there a chance, OP, that the gearbox needs a service? Maybe chat with a local BMW indie garage?
I suspect that’s mostly because modern diesels are all turbocharged, so mapping can change both fuelling and boost, whereas petrols have, until recently, mostly been nat. asp. so less opportunity for tweaking. And the new generation of turbo petrol engines tend to be small, and highly boosted as standard, so less susceptible to upping the boost for more power.I think it tends to work better with Diesel engines than it does with petrol?
my son keeps on about remapping his engine !!!! as his very high insurance premium is paid by me i am not keen !! i guess one has to tell insurers its modded ??? would it affect emissions as currently ulez exempt
Indeed! If he can afford a remap, he can afford his own insurance!I am fairly sure that it would affect insurance and emissions, and not in a good way.
Let him pay his own insurance, then he will be less keen

I suspect that there might be different tune levels of the same Mercedes base engine, with mine being one of the lower tuned ones - hence the reason why it's capable of being increased that much without any other mods. I'm quite tempted!
It’s possible that the engines with a higher state of tune from standard are built with stronger components so some research might be prudent.
