I think it is mostly due to the Euro 4 (I think) emissions that the PSA engine has to adhere to, it has much tighter emission control and a more complex management systems monitoring things. You have electronically controlled EGR's and DPF's etc that all fail with just pootling about.
The 1.8 is an earlier Euro 3 engine (again I stand to be corrected on this), so although the EGR is electronic, it's performance is not monitored so you can blank it off without issue (which I have done), and there's no DPF's etc to worry about.
The PSA engine is supposed to be a very good bit of kit, it's just the shite that is bolted to it!
The mk4 mondeo would have to comply with euro 4 but I don't think it has a dpf on the 1.8.
Either way we are starting to buy 1800 mk4 mondeo's for taxis to replace the mk3's.
