im still working on trying to cure the old lady's beetle 1.8T that has malfunctioned. i have a few 032DL ECU's from parts cars and i tried one of them in the beetle. the car runs but the cooling fans keep fluctuating from high to low, like not on/off but like variable speed when the key is on or the car is running. i figured this would work because my GTI 1.8T was factory with the same 032DL ECU and my car is narrowband 02 but has VVT. the beetle is obviously narroband 02 but no VVT but i feel i can edit the file to shit off the VVT and it should have been good to go. in my car im actually using a 032HS BIN and i dont have a problem as well. only reason i chose the 032HS BIN was because it had a fully defined XDF already posted here so that made my life easier. i even tried loading the same 032HS BIN from my car into the spare 032DL ECU for her car and it still does the same stupid fan thing.

over all is there something different in the wiring pinout that im missing from the beetle to the golf/jetta that makes the beetle fans go crazy? or did i read wrong info and the ECU im using is really wideband? im just confused because one post said if the car has the VVT solenoid its wideband but my GTI has VVT solenoid and narrowband upstream 02. maybe my car is a factory freak.

Or at least list engine codes. OP: you basically asked I have a problem help me. Like Adam said more info is needed in order to help you. Although  the beetle must be drive by wire, the 032dl ecu would not of plugged in if it wasn't. M5.92 has a different harness plug. Awv>aww shouldn't have a issue. Both wideband and vvt. Op must have a narrowband early model? Does your big have vvt? If not then it's narrowband and 032cl is the file you'd want to use on the correct ecu.
Good luck

Well that's part of your problem. 032dl and 032hs are wideband with vvt. So like I said ^^ if you want to cross flash a file you'd need a 032cl ecu or equivalent and use that base.

i actually have a CL ECU thats known good but i cant find a good tunerpro XDF for it, i wanna be able to disable downstream 02, EGR, SAI pump, tank vent valve, N249 etc. i know people dont suggest you remove the N249 but i did on my car and its one less headache i have to deal with when it fails. i have my car narrowed down to 4 vacuum lines instead of the mess it used to be. the problem is when i use the i use the 1mb ECU is this fan issue even if i do convert to widband and disable VVT. its like the beetle is wired different than the golf/jetta and i've been rooting through wiring diagrams to see if i can find the difference. i checked mitchell prodemand and it shows the 2000 beetle as having a wideband 02 so right off the gun i believe their diagram is wrong.
