petemcr 10 Posted May 7, 2014 Anyone got any info on what software to use for scanning OBD1 VR6's, I've got a converter from OBD2 - OBD1 however VAGCOM won't read any codes as it won't detect the ECU Also does anyone know if VAGCOM on an OBD1 VR would help find out a no start issue, I always thought the on board diagnostics were very limited on OBD1 but I'm being told to scan it Any help would be great thanks Quote Share this post Link to post Share on other sites
MikeVR6 0 Posted May 7, 2014 I bought 2 of these Bluetooth ODB reader adapters. Neither or them would work with my VR6. Although they worked fine with my ODB2 Mk4 Golf. I then bought a "VCDS 12.12.0 VAGCOM VAG COM cable" from Amazon. This is a real cable and works 100% with the free version of VCDS from the VAGCOM website. Make sure you set the Latency on the virtual com port on your computer to "2". You will be able to interrogate the ECU, ABS Controller and Immobiliser. Read fault codes. (Although you'll only see detail for the first code in the list. The rest you can lookup online.) Clear fault codes, look at measuring blocks. Basically all a novice user needs. The immobiliser controller is probably of most interest to you. If the car won't start at all or intermittently refuses whether hot or cold. It's probably the transponder key reader coil in the lock barrel. Check the connector on it behind the dash near the headlight switch. Mine had those symptoms and I just had to clean the connector with some contact cleaner and a cotton bud. Quote Share this post Link to post Share on other sites
