White smoke and white residue on exhaust

[Peterm69uk]

Hi, hope someone can help.

I have a DS3 16 plate 1.6Bhdi Prestige 18000 miles, today after travelling around 30 miles I noticed lots of white smoke coming from the exhaust, I drove another 15 miles until I stopped and called the AA. They arrived about an hour later but it seemed to have stopped, even after they followed me for 4/5 miles to check. However It started again on my return journey and the inside of the exhaust is covered in a white residue.

Any ideas what it is? The AA Technician checked oil and water and didn't think I had any reason for concern.

White smoke and white residue on your exhaust can be a sign of several issues, such as coolant leaks or burning oil. This could indicate problems like a blown head gasket or cracked engine components. For those who enjoy smoking, the best e dab rig can be a great way to enhance the experience, but it's important to ensure your vehicle is running smoothly to avoid any maintenance issues. Regular check-ups and timely repairs can help prevent these problems.
