As above, is the battery the correct size for the vehicle?On first start-up of the day I get special programmes not available bong but it instantly clears and can use the programs select as normal. As mentioned earlier in the thread I again questioned the battery. Had it tested at kwik fit and they replaced it under warranty as they wasn't sure from the readings if the battery was at fault. Since new battery fitted I still get the bong but it clears soon as the error pops up and all seems ok no errors on dash or suspension issues.
