Pay attention to fuse lock bit...if they werent set properly before.

i do update with progisp using projects file, and with avrdude. no error in both cases. but still same error.

maybe i have to do the test on the car?

So is your OBD2 connected to +12V while you are doing test? Connect to the car and retry.

Hi, Please help,

Ok I have a VAG171 and I can successfully flash via PROGISP. The problem is when I power down and connect USB the LED stops working and it is not recognised. I can reflash but cannot proceed. I have also been able to VAGCOM_EEWriteLang successfully. I think the old protection is reflashing and making unusable?. Can somebody direct me to what chip needs removing or tracks that may need cutting.

I have also installed 17.8 and cannot get it to validate with V5.1 or V6 VCDSLoader?. Any help much appreciated.

I am doing this because I have never manage to get CAN:Ready on my system.

Hi friend. Which pin is vcc on isp socket? do I need to use the v4 or v6.1 loader to 17.8.1 akp version? Thanks

Hi, thanks again to all, I have tried on the car with and without jumpers.......'Can:Not Ready'

This has never worked from new so I am thinking it may be a bad lead.

Just for information what do the jumpers do on this lead?.

Thanks again.

**hid3** · 3rd March, 2018, 12:12 PM

It's not clear regarding the jumpers. There is a theory that one is for the Aes chip, another of K-line (or L line?). I have tried with both jumpers shorted and it works fine.

BTW, what car are you testing on? Maybe your car doesn't have CAN at all?

Hi,

It is a VW Passat 2012 Alltrack B7. It does have CAN. Also checked on Seat Leon 2012 (before reflash) always same response.

Thanks,
