I have a few issues with my Mondeo.
I've been advised my car has a belt and chain system but Ford says only belt; can you confirm? It's a 2012 Mondeo 1.6 TDCi.
Also had issues with engine rattle after a dealer changed injectors. He says they need time to relearn. I have symptoms two weeks later still. Just wondering is this accurate because the dealer didn't mention chain or fuel pump. How long should the ECU take to relearn injectors?
Also, the steering wheel is shaking under braking. Should a dealer replace worn discs six weeks after purchase?

Hi Niall,
We asked Ford Ireland about this for you. First of all, it was confirmed that your car has a timing belt, not a timing chain.
With regards to the injectors, a longer response was given:
"Mondeo DV6 has a Continental fuel system and the fuel injectors fitted on this system have correction factors on them. What this means is that they have a unique ID number that the engine's PCM need to know so it can operate them. The pump has nothing to do with how the injectors operate and its role is simply to bring the fuel up to the high pressure demanded by the system. When an injector is replaced the PCM needs to know the new number of the injector installed. This is inputted using Ford IDS Diagnostic tool. If the injector is installed and the correction factor is not learned using the Ford Diagnostic tool the vehicle will not run at optimal level and the engine may exhibit excessive noise and emissions."
Finally, with regards to a shaking steering wheel, that could be something as simple as a wheel going out of balance, so check that before you consider changing any brake items. Whether the dealer should replace warped discs after six weeks is not so clear - it really depends on the terms of your warranty.
