Just got home on my usual 14mile trip from work, the last 10 miles of which are along the A3, so at anywhere between 60 & 80mph. On pulling up outside home, a great cloud of exhaust smoke rose from the front N/S wheel arch and continued to be seen for many minutes more. Now, I suspect as I've previously posted, that the EGR pipe has fractured, but would you really expect to see so much diesel smoke??? Any suggestions gratefully received??
