Hi Neil I hope you are well . Do you have access to a diagnostic scan tool ?
Customer
No

Ok this is the first step . The sensors I. The thermostat housing are very common to fail causing the issues you are experiencing
Customer
Ok I thought it sounded like potentially a temperature sensor fault- would this bring up the engine management light and put the car in limp mode without causing the temperature gauge to go up

it’s actually quite common . It requires complete thermostat housing replacement to cure and a modified piece of wiring loom
Customer
Eat replacement ? Any idea of cost ?
Customer
Easy replacement ? Sorry

Average cost is around £250 . Around 1 hours labour to replace
Customer
Problem I've got is the problem goes away for 4 or 5 weeks then it comes back which is a problem because it's gonna start getting expensive if it's not that ! Would peugeot be able to diagnose confidently

If it’s been in limpMode a fault relating to this will be stored
Customer
It has been in limp mode a friend of mine plugged their diagnostics tool in but no faults were logged I assume Peugeot's would be a more powerful tool

the dealer tool will access far more
Customer
It's very intermittent though is this a component that would fail permanently or is it a part that could fail intermittently

Intermittently
Customer
Is this part and the modified loom easily available ?

Not sure if my girlfriend has the same issue her comes up as misfire on cylinder 2 . Orange warning ligh comes on goes into limp mode, changed coil on cylinder 2 , plugs and injector on the same cylinder.. The warning light went off for about 5 months but a few weeks ago come back same fault code misfire on cylinder 2.. Peugeot don't know what it is and other mechanics don't know either, so if anyone has solved the same issue I would appreciate if you could let me know. As a say seen a lot of people with a Peugeot 208 around 2014 to 2015 plate all have the same issue. Warning light comes on goes to limp mode and fan kicks in. It runs after the fan goes off but light stays on . Then might reset itself after a couple of days
