Hi all

I have a 2018 Peugeot 108, with the 1kr fe engine, so it’s been extremely reliable in that department. Mikiage is 60k, and I’ve had it for 3 years (I do around 11-12k miles a year, so it does get a lot of use). I live in the north west, so obviously a lot of salt on the roads in winter. The car has a good service history.. gets serviced every 8k miles or so.

It had its MOT yesterday, and had an advisory for corrosion on front subframe (not excessive). This was not mentioned on my MOT last year (which was done by the same place and same person), so rust is likely progressing quickly.

I’m just deciding what to do from here….. and it would be good to have some PH opinions. Just for context, I’m looking at paying off the mortgage in the next few years, so I don’t want any further unexpected car costs.

1). Do I get the front subframe replaced? I’m guessing this will be £500-600 (correct me if I’m wrong?). Whilst doing this, they may find other stuff to repair such as rust etc. I also need to factor in the rear subframe needing to be done in the near future. My cars only worth about 2.5k ish anyway. On the positive side, getting this work done will mean that my Peugeot
is sorted - at least for a couple of years.

2). Do I get a new car? If I get about 2.5k in part exchange for the Peugeot, I could get something like a 2024 plate Suzuki swift for about 10-11k. This means that I will be putting 8k towards a new car, but it also means that ill (touch wood) gave trouble free motoring for the next 5 years, so I will save money that way. The swift is also a bit more substantial, but the Peugeot still does its Job well.

Sorry for the rambling, but any comments welcome!

If it isn’t excessive simply treat with Dinitrol

It will be years before its an issue.

Clean it up with a wire brush then spray some underseal on it - it should be fine. It could also just be a pedantic MOT tester and you might not get an advisory next time.

the " not excessive" part means you can save it /get many more years from it

wire brush it and apply whatever rust prevention you believe in , dinitrol , bilt hamber etc and check it every year

You could wire brush and paint it.
Or you could forget about it and just use the car as before.
Either way it will last many years more.

when I had an advisory for corrosion on the subframe of my last car, I asked the MOT bloke how many years it had left in it.
FWIW, I got the same advisory 3 years running, the last time he suggested changing the car.

It might be worth getting someone to do a basic job of applying some anti-rust jollop, I wouldn't expect miracles, but it might mean you get an extra year or two.

Or, if the subframe really is only £600 to change, then that would be worth considering in due course?
Sometimes subframes rust while the rest of the body is fine, it would be good to have model-specific advice.

But once a car has a corrosion advisory on its MOT history, a lot of people aren't going to buy it.

Very common on this model, Aygos and C1’s, I looked at mot history’s for quite a few, it was an advisory on almost all, including one at a Main dealer.

Wouldn’t put me off as all the advice above is what I would do on my drive in an afternoon.
