Hi, In last few summer months I encountered problems with warm engine starts. I have Avensis T25 2.0 D-4D 85kW car make 10/2004. The car starts cold engine without problem, but, when the engine temperature rises up to operating value (80-90 C) the engine is problematic to start. Starter runs for 30-60 seconds to get the engine into operation. During the starting, the engine shakes and no black smoke comes out from the exhaust. Reading this forum through I performed following repairs to my car,
