Hi All I'm new to bimmerforums and am desperately hoping for some advice. Literally between a rock and a hard place. Story to follow ( there are a lot of things I would have done differently in hindsight but I am where I am now unfortunately).
I was driving my 320d when it lost power october 2016 - AA were called and recovered it to a local garage ( one who I have used off and on for all my bmw's over the past 6 years or so). The garage diagnosed this to be an issue with a stretched/broken timing belt and advised I would either need a replacement engine or have mine reconditioned.
They advised me to purchase an engine code N47D20C. I searched the internet for quotes and came across an engineering firm in Scotland who supplied me a used recon engine for £1200.
This was shipped to my mechanic who fitted it. He advised car was left on the ramp and ran fine for 2 hours then developed a fault - loud banging noise.
I called the engineering firm and complained - they advised this would now be a warranty issue eventhough I argued that the car hadn't left the ramp. I also complained that this would incur extra labour charges that they should pay. The company advised they could uplift both engines and recon my existing engine and return it.
So they reconned my engine and sent it back. The mechanic fit it but advised the engine was loud - rattling sound and it was the timing chain most likely at fault.
I complained to this firm again who once again after countless phone calls and arguments agreed to once again uplift the engine for repair - I agreed reluctantly when the owner/director himself called me and said he would personally oversee the repair.
So the engine was reconned a second time and received 2 weeks ago and fitted - Once again it was the same fault - very loud timing chain.
I have been calling the engineering firm for 2 weeks and getting nowhere - I have advised them to call the mechanic and deal with him directly - they keep saying they will but this hasn't happened. The mechanic in the meantime is happy sitting back claiming it is definately a fault with the engine and not the fitting. So I'm totally stuck and and pretty heart broken with the car 4 months later still gathering dust.
I had garage repair cover with the AA who agreed to pay the first £500 of the repair but now I don't know where I stand with that either...
Would anyone be able to advise what could be possibly going wrong technically and how I should progress I'm totally hitting a brick wall and financially I just cannot afford this..
