Hi,

I have a late-2017 Fiesta 1.0 Ecoboost. My engine management light came on this week and I took it to the local Ford dealership to get it checked out. The OBD is aparently saying I need a new catalytic converter and Ford have quoted me over £1300.

Rather than just accept it, I'm concerned as to why a car of 4-years and 35,000 miles should have a failed cat. I also enquired whether there would be issue driving it around for a bit before replacing (with the intent being to get a n independent quote). I was told that would be a very bad idea as the cat could break up and get ingested into the turbo at which point I would need to pay £8000 for an entire new engine. Unless I'm mistaken, isn't the cat downstream of the turbo and very unlikely to cause engine damage?

Could anyone give me some advice about my predicament...if £1300 is high etc?

Thanks!

Hopefully an expert will read your post and suggest something. My non-expert thoughts are that perhaps the fault is with one of the lambda sensors? I’m assuming it’s a petrol engine.

I’ve no idea what a replacement downpipe/catalyst would cost but I’ve found Rates Ford on eBay to be very helpful, and reasonably priced for genuine Ford spares. Something like a Milltek downpipe with sports catalyst would cost £500 to £600 for the part.

I think that replacing the downpipe/catalyst is fairly straightforward as it’s quite accessible, and as you’ve said the catalyst is downstream of the turbo. Whether it’s safe to drive as it is I’ve no idea. Could be worth having the car looked at by a Ford specialist rather than a Ford main dealer?

Where are you based OP? Any recalls on the car that Ford haven't mentioned? Definitely worth a bit more investigation and will almost certainly be a cheaper option. Stick the reg up and I'll have a look around for you (Ford dealer here). I'm here today and not back til Tuesday but will do what I can

Bit of a late reply, lol.
Walk away to a garage that knows what they are talking about, "cat ingested into turbo", lol and another lol.
