hodgkinsons 0 Posted April 5, 2006 Question :My 94 VR6 has just had a new battery fitted having been stood in the garage over winter with no battery. I ran the car stationary for a while to warm it up and it did run a little rough at first but this seemed to smooth out after 5 mins or so. It passed it's MOT yesterday with a clean bill of health including the emissions. Why would I need to go through the ECU reset procedure and basic settings procedure to reset the ECU if the car is running ok and has passed emision tests no problem? Thanks for any advice given on this. :roll: Quote Share this post Link to post Share on other sites

Supercharged 2 Posted April 5, 2006 It would have been reset as the battery was off - If this happens then you really should go thru the basic settings to get the most out of the engine but there is no rush if it running ok atm. Quote Share this post Link to post Share on other sites
Trig 0 Posted April 6, 2006 Yep leave it as it is mate. Need to be careful with resets, it was whilst doing mine that I broke my ECU. :( Quote Share this post Link to post Share on other sites
hodgkinsons 0 Posted April 6, 2006 So am I correct in thinking that there's no point in doing any of the driving reset stuff either if I'm not going to do the basic reset procedure? Quote Share this post Link to post Share on other sites
Trig 0 Posted April 6, 2006 If you've already been driving it around, no. As Supercharged says though - you should get it hooked up to a VAG-COM to run basic settings. Quote Share this post Link to post Share on other sites
hodgkinsons 0 Posted April 6, 2006 So it is advisable to get it hooked up to VAG -COM at some point to get the most from the engine. Isn't this what you were doing when you broke your ECU? anything to avoid here then? Cheers Quote Share this post Link to post Share on other sites
Trig 0 Posted April 6, 2006 No it was after the reset that I got problems, I think I disconnected the battery wrong and sent a surge into the ECU or summet. There is a guide somewhere on how to do basic settings but whoever you take it to for the VAG-COM should be able to help. Quote Share this post Link to post Share on other sites
hodgkinsons 0 Posted April 7, 2006 ok great, thanks to all for your help with this, think I'll have a word with a local VW specialist might get it done when it goes for a service in the next couple of weeks. I'll report back if any probs. Quote Share this post Link to post Share on other sites
hodgkinsons 0 Posted May 15, 2006 I've got a bloke called Andy Jackson to service the car for me and do a basic settings reset for me, seems to be knowledgeable drives a VR Vento himself. He's based in Leek, Cheshire at A&C services if anyone is looking for a decent VW sepcialist in that area. Quote Share this post Link to post Share on other sites
