If it’s a 2001 then yes, go ahead and buy parts for an AWM.

I assume the car is running? Most likely just a replacement head. Any head from any 1.8t will work except for the AEB.

stupid ? i was out working on the car yesterday trying to find vac leaks that would cuz turbo to surge found a few stupid 2nd air injection why is it even in the car for what to make to engine get hot faster dont need it
but while i was poking around it looks like the block was never changed due to bell housing bolts looks like they were never touched so is their a way to tell the block is original besides the engine code on the head

ps. also my maf is shot and i have a code for the cam actuator circuit witch im assuming is the vvt piece of crap on the back of the head witch will more than likely cause of surge with the timing jumping around
