Ford Fiesta 1.4 tdci 2007 - 1.4 tdci 2007 engine shaking +FAULT CODES - ford321

Hello everyone

I have a ford fiesta 1.4 TDCI 2007 with 50.000 miles. I have a rough idle and engine shaking until 1500 rpms, higher than that it calms down. No other symptoms, no power loss, no smoke, no smell no nothing, just that shaking. And it also shakes when I start driving in the 1st gear.
I did a reading and it gave me the following codes:

P0191 Fuel Rail Pressure Sensor Circuit Range/Performance
p0238 Turbocharger Boost Sensor A Circuit High
p0263 Cylinder 1 Contribution/Balance Fault
p0266 Cylinder 2 Contribution/Balance Fault
p0269 Cylinder 3 Contribution/Balance Fault
and p0504 or p504 something about the brake switch


I was advised to upgrade the pcm (ecu).

Any Ideas ?

Any help would be greatly appreciated

I got the same fault my local garage did a scan on it and those faults appeared that you mentioned. I got the cyclinder contribution faults come up for all 4 cyclinders. The garage mentioned its likely that one or more of the fuel injectors are faulty. Hence causing the engine to misfire and shake when running idle

Do you get a lot of smoke being produced? Poor mpg? Poor acceleration on hills? This what happens in my car car

The garage mentioned I need to get the injectors out and get them tested but by then I decided to get rid of it an get an 1.6 tdci instead they seemed to be more reliable. spend loads on my current 1.4tdci getting it fixed problem after problem (previous issue was injector seals)

I hope you get your fault fixed
