Hi Folks,
Having fixed my limp home mode issues last week by replacing a faulty Vacuum solenoid I now have brand new errors causing Limp Home Mode!!
It seems to do it at 70mph 5th gear only whilst acclerating.
P1105 - Barometric Pressure not plausible with Boost Pressure
(FA) - Present
P0105 - Barometric Pressure not plausible with Boost Pressure
(FA) - Present
P0110 - Intake Air Temperature Sensor Circuit High Input
(07) - Present
P0234 - Boost Pressure Control Circuit Negative Deviation
(5A) - Present
I had the barmetirc error a last month so I took off the sensor and cleaned it (by blowing on it ha!) and it didnt occur again. Funnily enough another member who works around the corner had the same issue on his 2.0DTI the same week and I cleaned his for him as well and porblem went away.
Does it look like the Barometric sensor is on its way out though? I havent seen the 'P0110 - Intake Air Temperature Sensor Circuit High Input' warning before and as for 'P0234 - Boost Pressure Control Circuit Negative Deviation' I had replaced the boost sensor last week because of the same error warning thinking it was playing up.
Where is the Intake Air Temperature Sensor?
Is one sensor failing and tripping off all the others?
My other hunch is maybe the butterfly vavle in the Inlet manifold elbow may be getting stuck paritally shut and affecting the boost/air pressure in the system although the car drives perfectly until LHM kicks in.
What do you guys think?
