I too am a big fan of remaps having had it done on previous (non) Volvo cars.

The thing is when I bought my 2008 V50 2.0D secondhand it had a Diesel Tuning Box fitted to it, which I could have removed if I wanted to. Anyway I asked in the local tuning shop about a remap and was told that as the car has a 'Siemens' ECU (and apparently a Citroen engine ?) it couldn't be remapped as the ECU can't be remapped. I didn't argue as I'm afraid I'm not very Technically minded.

I think the tuning box can either be switched off all together or set to Low/Medium/High as required. They recommend to leave it on Medium.

I have to say that, although I would rather have it remapped, the difference between having it switched off and set to Medium is like night and day. With it set at Medium the car is so much more responsive through all gears, overtaking in 6th is an absolute doddle. I have had it turned to High a few times and it is a different animal altogether. I think I will stick with it just now.

Is it the case that my car does have a Citroen engine ?

It is a EuroIV version, therefore no DPF fitted thankfully.
