Hello, have there a question: My Meriva 1.7 CDTI 100PS (Z17DTH) nailed the first meters after starting very loud, so I think the engine is broken7. After a short drive the nailing is less. But is louder than before. Now my FOH has told me that this is due to the injectors. One costs €440,- plus installation. But since you can’t test, which is broken, all 4 new. Cost min. €2000,-!!!! Do you have here another idea, which is not so expensive??? Thank you for your Hi If Steve
