I'm having trouble connecting using VAG Tacho 5.
My ECU is IMMO off, could this be the problem?
When selecting the RB4 profile in VAG Tacho it doesn't connect.  If I select 'Connect any' then it will connect but there are no useful functions available.  Can't read EEPROM whatever I try.
I will post screens of specific error later tonight but I had read around that IMMO off could cause an issue so I was hoping someone here may have had experience with this already.

Thanks

Yup clone, don't really have much choice in the matter as I can't afford a $950 tool.

Scanned a friend's 2004 Audi 3.0 that also had an RB4 and wasn't able to read or connect properly.  His ECU is stock as far as we both know so I think I can safely conclude the clone tool is shite.  So I might spring for a VAG Dash clone or try to exchange this tool for another of the same :/ we'll see...

Where'd you get it?

http://www.opelinfo.com/ has it for ~$515 US but their distributor
http://www.aetools.us/vagusb.html sells it for $950

If it were $200 to $300 dollars I think I would save a bit and do it.  Maybe it'll show up used in the classifieds but until then a $36 dollar clone that might or might not work is worth the savings especially considering I may only use it once.
