Title: Golf Mk 4 - 036 906 032 D: is it M5.9.1 or ME7.x ? Post by: Super1600 on January 16, 2020, 02:05:21 PM Hey guys,
I got myself an ECU from the junk yard for testing purposes. It's coming out of a Golf 4, I pulled it out my own. Engine was already missing, but very likely it was a 1.4 16V. Now I am confused by the information I found on the internet. Every page I found says that 036 906 032 D should be ME7.5. But the plug is definitely M3.8.x/M5.9.x... Looking up the part no. at the "reseller" page of EVC, it finds results not only for 1.4 16V (ME7.5) but also 1.6 16V (ME7.1). I only have a bench harness for ME7.1/7.5. So I can't read it with MPPS. Is anybody able to identify the ECU model by the chips on the board? Memory is AM29F400BB, eeprom is a 95040. thanks! Title: Re: Golf Mk 4 - 036 906 032 D: is it M5.9.1 or ME7.x ?

Anyway my noob questions continue ;D -it is the fourth ECU I opened (2x M3.8.2 and 1x ME7.1) and I noticed that the PCB is shorter -> is it shorter on all ME7.5? -or is this maybe a "reduced" ME7.5 with less functions/outputs? Because the plugs obviously have less pins than on what I know as common ME7.x plugs Title: Re: Golf Mk 4 - 036 906 032 D: is it M5.9.1 or ME7.x ?

Post by: Super1600 on January 21, 2020, 12:20:05 PM so just FYI:
I compared pin outs of 8D0 907 557 T (M3.8.2 from Audi A4 engine code AEB) to 036 906 032 D (ME7.5 from Golf Mk4 engine code AXP) which obviously share the same plug. Result: they couldn't be more different. Only ground, injector#4 and TPS#2 are on the identical pins. The rest (even power supply) is different. Yes - I was hoping for the 'holy grail' of M3.8.x to ME7.5 conversion. No luck today. ;D |
