Hello everyone!
This applies to Alfa Romeo Fiat and Dodge that use the same variant of the engine...
This Alfa Romeo Mito QV (1.4 Multiair 170hp) was going randomly into limp mode, would not rev more than 1500 rpm, and was giving fault with all the modules in the car. I had previously removed and cleaned the throttle body inside the gear mechanism where the potentiometer lies... It was full of blak dust there and the black carbon tracks on the pcb looked warn down. When the problems came back about 6 months later i replaced the throttle body with a new one (the old one had about 230.000km) that solved the issue.

So here is a detailed video of how to replace the throttle body on a multiair engine. It might help someone to DIY.

Part number:
BOSCH 0 280 750 137

The new throttle body did not need any programming at all. I checked with MultiECUscan and the status was "LEARNT". Maybe because i removed the battery it reprogrammed the throttle body?

Any questions leave it in the comments below!
