Hang on - let me understand this. Did they get one car? or three? Remapped to what level of performance (and starting from what)? Did all remapped engines (if more than one) fail similarly? Or was it only one?

Sorry, I forgot to tell you they used more than one car. One car each. Altogether they had about ten Golf's.

Please pardon my insistence - but do tell us more. Did ALL the cars fail similarly? or just one? After pumping them up to what level of bhp/Nm? What engine did they have to start with?

I'm sorry - my German is very very limited (mostly learned from Bach, and I guess the vocabulary isn't quite there... "Meine seele erhebet den autobahn" does not sound very appropriate), or I'd read it out on AutoBild.
EDIT: cross posted with your post with the scanned page! Thanks.

Here's a part of the article:
[snip]
[snip]
1) Judging from the pictures these seem all to be add-on tuning boxes, not remaps. AFAIK, a tuning box basically increases fuel flow, but little else. Which is consistent with the fact that all these mods increase consumption and particulate emission (plus problems with combustion chamber and exhaust gas temperature). A well designed remap will alter more parameters than simply fuel flow/injection timing.
2) Regardless of what they are - disappointing results! Torque up 12% on average, BHP up 7% - so the torque improvements are not sustained through the rev range. And ALL the enhanced cars end up with less power than a BMW 320d/520d (163 BHP), though with higher torque (340 Nm)
I wonder how current "popular" remaps on this forum (DMS, e-maps, SuperChips) fare in terms of real, measured performance enhancement on the average customer's car against one-off figures from the test car. The only objective evidence that I know of is CliveD's acceleration times pre/post DMS remap, but I can't be bothered digging them out to calculate implied torque/bhp improvements.
I also still wonder whether the damage on the pictures is the result of one (or two, or three) "dilettante" remaps, or whether it is representative of the average condition of all the cars.

Glad there finally is someone who knows, i guess from experience.
Had 4 remapped diesels now, the last one sold with 140k on the clock and not the slightest problem.
One remapped car I wrote off by putting it on the roof. The insurance (a big one) didn't give a toss about different wheels, suspension and let alone remap.
If you want to keep yours as it is, perfectly fine and fully respect your decision. Please don't try to tell us, that we are idiots and you have the wisdom.

It's cowboy technology. The firms that peddle these remaps will have done a fraction of the road testing that the original car would have undergone by BMW, and likely no road testing at all - just bench testing.

After reading the whole post, I'll still go with remaps, I disagree about the stuff that the originator said. Anyways, he's probably gone since he hasn't replied yet. Bu i want to ask, if its possible to remap a 525? I want to remap mine. If yes, wat company?
