DTC Code P1198

[JAECOM]

Hi

New on the site so hope someone can give me some guidance.
I recently had a warning light appear on my 407 "Depollution system faulty". Took it into my local Peugeot dealer and they performed a download and it cleared. 2 weeks later it re-appeared and again I took it to my garage who said it required a new fuel pump at the cost of over £700. At home a friend of mine attached a diagnostic reader which reported a DTC code of P1198 which reads "Pump rotar control underfueling" Do members feel such radical action is required (changing the pump) or is it such a generic fault it could be a smaller problem. At the moment the warning light is no longer there but I wouldn't be surprised if it re-appeared. Has anyone had anything similar?

Thanks for any help

would you not notice it in the performance if the fuel pump was knackered ?

how`s it driving ?

my mechanic always wants to know how the car is performing , he say`s the llights /warnings that come on are don`t narrow it down enough ,

i.e last time i had a reading it was no pressure in the pump and none in the rail,
bring it to peugeot they would have changed pump ,

it was a dirty filter !

( i only worry about red lights now )

Is your car diesel or petrol?

My 407 (Diesel) is driving fine and I am tempted to ignore the advice from the garage and just see how it goes. I just wanted to know what people's thoughts were and if anyone had experienced anything simialr. Appreciate your comments so far

Yes my wife has a 307HDi with the same fault only thing is hers keeps going into limp home mode. Car drives fine up till then so I think it's going to be a sensor, I have ordered a fuel pressure sensor as thats only £30 and easy to fit not the £750 for the pump. My thinking is if the pump is playing up the car would be playing up when it drives! also it only goes into limp mode when it's warm outside? how can that be a pump.
I'll let you know if the sensor works!

The fuel pressure sensor is not supposed to be removed from the rail. It is torqued on for it to work correctly.

The car has just had a full services,
When the code was read the first time it said 1138 so I had the wire loom changed as I was told this is a common fault? then that error cleared and it now comes up with 1198, 1199 I think he said.
What setting does the sensor need as I think he may have already removed it?

Who knows! Its not supposed to be removed!!

[merrl]

why would someone make a sensor that shouldn't be removed and removable?
It was a peugeot engineer that removed it I'll ask him why he removed it when I take it back!
