Avensis T3-S D-4D no power no start black smoke

[ANTHONY4]

Hi i have a Avensis T3-S D-4D it turns over with key but will not start and also will not jump start but it will bump on a hill. When engine running it drives ok until it warms up then it loses power then power comes back for a bit then back to no power. But i have noticed that when driving with no power black smoke comes out of the exhaust then when power comes back it releases a lot of black smoke at once then runs ok until loses power again.Is there anything i could check or do myself before i take it to a garage any advice please

The part of no power and black smoke sounds like a classic case of blocked EGR valve. Either clean it yourself or have a garage so it, but it has to be done properly — soak it in carb cleaner and go at it with a toothbrush everywhere, also rotate the valve stem to clean it from all sides.

While I can't guarantee it will cure the starting troubles, it probably is the cause of power and smoke issues when car is warmed up. Clean the EGR and go from there.

Agree, sounds like EGR needs cleaning
