Nope, you'll also find a lack of evidence to back up the catastrophes predicted too.

 

Remapped my 530d 18 months ago and 15,000 miles, been fine. You just need a professional map done and treat the car with respect.

 

Is it ok to get high milage ones remapped? Mines at 169000

 

I'm in the same position. Mine is an auto with 139k. I need to map do improve performance and economy as it's really thirsty locally. But it seems so expensive to remap! What sort of mpg gains can be expected inner city?

 

Ali, seeing you're in London,maybe we can get together and do the remap at the same time and possibly get a good discount from someone?

 

Yeah that would be good if we can find a tuner who would give us discount

 

Which part of London are you in?

 

im in nw london neasden area

 

Diesels make much better candidates for remapping if you ask me,

1/ If you take a diesel engine apart, even at ridiculous mileages, wear is likely to be non-exsistant (diesels normally fail due to a failed ancilliary parts, turbo, swirl flaps etc).

2/ The standard power output is likely to be deliberately strangled from the manufacturer, (most diesels have a turbo, not just the high performance versions).

3/ No worry about pinking due to weak mixtures or overboost, in fact the boost does not even need to be turned up as diesels normally run with an excess of air for emissions reasons.

4/ Diesel engines are inherently "strong", with heavy duty components.


The only thing I would do before remapping a high mileage one is check the turbo hasn't got too much free play

 

The weakest part of a high mileage car will be the gearbox, especially autos. If you up the power and turn it on with a vengeance, you will soon blow the box.

 

Looks like I'm good to go then my cars had a recon turbo 20,000 miles ago

And I got the gearbox rebuilt 7,000 miles ago

 

Is it really worth remapping with the hope of improving urban mpg?

 

I don't think you'd get big gains, what you'd get out of it is faster shuffling in traffic. The MPG gains are seen in steady driving, so it depends on the mix of cruising to traffic driving you do to how good the gains are.
It's unlikely you'd lose any mpgs, but you won't see the same sort of gains a motorway cruiser would see.

 

Mines used mainly for motorway driving and its done a fair few miles 155k.
Been meaning to get a remap suitable for my driving use and mainly for some high powered kick ass fast & furious style overtaking adversaries such as E320 cdi! up the M6!!
But I was a bit dubious due to the high mileage but just read a one of kwempes posts and its convinced me of how sturdy a diesel engine can be so I think i'll treat my self next month with a good remap.
Enda, I did mail u a few months ago and still have your reply with your 'discount' so may pop down next month to get it done.

Did Ali or m_azing get a remap in the end?

Yea sure, just let me know a few days in advance and I'll set some time aside.

 

yes get it mapped, i had my 2001 E39 530d sport remapped at 110k

Covered 20k on the map, and i drive pretty fast everywhere within the law of course

it was a regular map. ie: not max power and still it made the car very fast. around 220-230bhp

no issues at all, was slightly better on fuel

get it done by a reputable mapper, or someone who has good reviews at least

 

here's a BMW e39 530d 192bhp 2002 we remapped for another tuned who tested the car on a dyno dynamics rolling road

it made 241bhp 430 ft at the flywheel after our Bw chiptune remap for more power and mpg
