Ant896

Good afternoon everyone. I'm hoping I can get some help. I have a lexus is220d 06 model. 144k and been very good to me for the past 6 years but I've now had the engine warning light come on with the VSC as well. I've used a diagnostic and it's given me a code P1386 which I'm hoping people may have experienced this and any ideas on what to do next and is worth repairing based on the age of the car. It has no issues at all when driving, no lag no limp mode no stalling so a bit lost what has triggered this. Any help is always appreciated

afternoon everyone im in need of any help or assistance anyone can offer on this issue. I have a lexus is220d 06 model done 130k miles and I've had no major issues to speak of in all the years I've had it. But after driving my son to school the car started cutting out and restarting instantly until it eventually cut out completely. After a couple of minutes and tapping the connectors on the battery the car lit up and started fine. Since then though I have found more regular that as im going to start after its done its checks it just dies so I have found tapping the battery is bringing it back to life strangely. I've replaced the battery, electrical taped all the wires as small splits on the casing but nothing major yet the problem consists. Anyone know or come across this before. Any help would be very much appreciated

I have a lexus is220d and after a long journey has now started blowing black smoke when I accelerate. Had the air filter done and treatment done to clean the diesel in the tank. Any ideas what this could be and costs involved to fix?
