I was thinking about remapping my car (2.0 TDI 140 hp common rail engine, CFHC). Basically I could get something similar to power of 2.0 TDI vrs version (~175 hp; ~390-395 Nm).

They guy said that it should not affect the life of the car. I know that he has a good reputation and maybe that's all more or less true but I'm worried about one thing: flywheel...

 

I have changed one (was lucky enough to buy a car with an already bad one) and a new flywheel+labour wasn't cheap thing. I'm hoping that my existing one will last for some time. And this remapping might affect that.

 

So, maybe anyone knows if the flywheel used with this engine (140 hp version) is the same that's used for Octavia vrs.

 

Any other possible disadvantages (don't mention the tyres - I know that their wear rate depends on my driving style )?

Did some searching on http://workshop-manuals.com/. Tried to find vrs gearboxes and found only 2 codes: NFN and KXZ - both in 02Q gearbox. My LHD is also 02Q (I'm not 100% sure that these are the only possible gearbox codes but haven't had more luck so far).

Could that mean that the same flywheel could be used in both (140hp and 170hp) cases?

I don't think they are the same looking on parts base but at the same time it looks like some of the 240mm versions are unchangeable.

Can't tell you any more than the part numbers seem different but if you do remap I'd like to hear how you get on as I keep considering it for my CFHC o2 :-)

Well, that's the tricky thing. If in case my flywheel (or anything else) dies then there's no proof that it because of the remap

I'll keep digging for more information but I think that I'll probably do that remap. At least I'll have once lived with a car a bit closer to 200 hp

 

Btw, about that link your provided:

03L105266BM is the same for both cases!

Not quite, one is 03L105266BM and the other 03L105266BN

Crap, it's like you say

That makes everything a bit more complicated...

After some thinking I finally DID IT!

Can't give much feedback because I just arrived and I'm not planning any long trips these days but even now I felt that it acts nice! Acceleration was way better.

 

But that's not what I'm willing to talk about. I've read a lots of topics here and I read even things like "just buy some remap box. Install it, then pay and you will get received map by e-mail. Install and will work fine"... that seems a bit weird.

Before remap together with garage guy we had a test drive (just to check overall condition of the car). After that he checked turbo because it was slightly suspicious (wasn't that bad after all   ). And only after that he did his work and even after that some testing was done. I understand that - this garage thinks seriously about it's reputation and doesn't map cars in poor condition.

What if your car isn't in that good shape and you don't know that? You remap it with some received file and it gets even worse...

Can't tell you any more than the part numbers seem different but if you do remap I'd like to hear how you get on as I keep considering it for my CFHC o2 :-)

 

Did some test drive today - well, this car feels way stronger than it used to be. Actually I have to learn to drive with that because there's no need to press accelerator pedal as much as I used to do previously. On the highway overtakings are much easier (can't complain about power of 2,0 TDI before remap but this beats it obviously) - just press a little bit and you are from 90 to 120 kph...

Nice, I like it

Hope it won't have bad effect on other car parts.

Just keep it well serviced. Regular oil and filter changes keep everything clean. I do mine every 5000 miles.

My work car

Keeping the car in good shape - well, that's obvious
I change the engine oil myself, so at least I'm sure that everything is fine with that (I do it at ~12k km).

 

By the way, I talked with garage guy about engine and turbo health and he mentioned that the greatest enemy is that 30-45 k km oil change. No matter how do you drive, it's too much.

He also mentioned some oil additives that are tested and found to be good (Prolong, Pro Tec) but you have to be careful with these - some are good but some burn and can be removed with sandpaper only...
