We use the same system as PSA. If you want a printout of your vehicle, let me know.

Agreed but I still think that all Bosch had a tank pump and all Siemens had a hand pump.

I think he wants to get more "powaahhh" out of his car with ECU remap.

@Charliedog7, scroll bit on top, where some1 already replied on "remapping ECU" and what + and - it brings. I decided to forget about it and just stick with "reliable" car with less power since at the end of the day, I realized I do not need it on my car and will buy a motorbike instead :-D

A remap on a manual will put more strain on the clutch and DMF though so be prepared for that to ear out quicker.

Marc, Sorry I got the flash thing completely wrong. I don't want more power, just want to diagnose the faults that keep coming up on the MFD. What is PSA and would you send me a printout of my vehicle VIN: VF7**************[VIN obfuscated, can be read by forum staff]********.
As always much appreciated
Bob
