P11aa fault p1946 fault turbo loss of power going in to limp mode

Unread post by Tottie88 »

While driving the other day a car went into limp mode and showed a engine fault after paying for a Diagnostic test it showed faults p11a and p1496

I have been to two garages to tell me it needs a new turbo at a cost of 1200!!!! Fitted. Its a 2018 306 1.5 it is booked in at peugeot to be 100% sure it needs one.

But i was just wondering if anyone esle can help 🤔

Do you mean a 2018 308?
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Whilst turbo failure was common on the early 1.6 16Vs it's pretty much unheard of on the later engines. Hopefully it's something else; but I imagine £1200 will look like a bargain compared to what Pug will quote if it does need a new one....

A search on P1496 suggests it could be an egr valve problem so may not be the turbo.
P11aa suggests the turbo pressure is not what would be expected. I would use a code reader with live data to see what values the MAP sensor is giving, it could be a turbo fault or even a MAP sensor fault.
Anyway a proper diagnosis is needed so only any faulty parts are replaced.
