Renault espace IV 150tkm 2.2 dcii 150 PS Initiale

Hello, I just wanted to hear your opinion. I have a Grand Espace 2,2 dci initiale with 150 Ps and 150tkm down. Must say, full workshop picking at the Renault dealer. Every year oil changes, customer service, just everything with cover even in the book (stamp). If the problem I got in the engine a clinking noise, you have heard for months, sounds a bit louder and defective, but my dealer said after a detailed examination, 2 days in the car dealer’s house I should leave it that way, It’s nothing bad, I’m just supposed to watch whether it gets louder or quieter. It’s been 4-5 months now and the noise hasn’t changed. I’m already driving 3 thousand kilometers at the time. It’s going through full and runs normal. What do you think of the statement. You think you can trust it. I’m not an experienced espace driver, I just switched to this car, which is a real wonder of space. I’d be happy about your opinion. Mfg and thank you Fire power
