        Seems like you got this solved.
        If he asks more than 25$ for one freescale sensor, then let me know, and I will give you the details where to order from along with part numbers.

            That's a very fair deal for the Bosch.
            The freescale sensor is not really worse in any way though, and their input voltage - pressure - output voltage formula is the same.
            Only thing why the Bosch sensor is better, is that it is perhaps a wee bit easier to install.

            Glad you got it sorted then

                Not sure about that, as the MAP sensor is not used for fuel injection and ignition calculation. Only to control the turbo.
                I would place some bets on one of your coils being bad...

                  dont know... as the wag com showed 3 errors... Lambda sensor, but had it changed 2 months ago, map sensor and something else i cant remember now...
                  and the coils have been changed a week ago

                    Better to write exact codes.
                    When does the misfire occur? Under high boost or when cruising?
                    Do you have a wideband on your car?

                          Wideband lambda sensor with a controller to monitor mixture... you probably don't have one then.

                          If you are slowly going uphill, not pedal-to-the-metal and your lambda is borked and showing rich all the time (which sometimes happens when they go bad), then your ECU will excessively lean out your mixture and you can get misfire...

                          If you go up a hill with full boost and pedal to the metal, do you also get a misfire?

                            yes in normal conditions if i get it foot flat thats it, it starts miss firing, but if i press pedal down gently it ok

                              Then perhaps one of the plugs/coils...

                                but i changed them, besides vag com would show that if coils would be the case
