Help! First of all I'm a n00b, sorry!

Second I looked on Google but didn't really find anything that seemed to fit.

For a couple of weeks the Engine warning light was flashing up for about a minute then turning off. Now it's and doesn't turn off! The car works perfectly, the only error I know is that I need to change a heater plug (I get the flashing light for a few seconds after starting the motor). I connected the car to Multiecuscan and got the following errors:

P0601 – ECU faulty (1): Signal low
ECU Memory Checksum Error
The reason for this fault is that ECU has received very low signal from the sensor. The fault is not detected now. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was not activated for this fault.
P0235 – Boost Pressure (1): Light on
Boost Pressure sensor A circuit malfunction
The fault is not detected now. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was activated for this fault.
U1601 – CAN Message TX: No signal
No help available
The reason for this fault is that ECU did not receive signal from the sensor. The fault is not detected now. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was not activated for this fault.
P0380 Glow Plug/Heater Circuit (1) Signal Low:
Glow Plug/Heater Circuit Malfunction
The reason for this fault is that ECU has received very low signal from the sensor. The fault is not detected now. Clear fault codes, and observe for future appearance of the same fault. Dashboard warning light was not activated for this fault.

I'm kind of stuck as I say the car seems to start & drive fine! Anyone have any ideas why it doesn't work?? :bang:

P.S.: BTW it's a Fiat Punto mk2 188 from 2001
· Bosch EDC15 Diesel Injection '99 (1.9)
· ISO Code: FD 86 07 98 F7

P0601 - Power train module - I think it means ECU fault

P0235 = your turbo boost sensor has a fault, but no info availible

u1601 = Your key wasn't detected by the ECU at start up (key code light on)
This one you can clear and ignore for now - unless the key code light doesn't go out that easily

p0380 = No signal from High pressure pump basically


All of this is making me wonder if there is a canbus issue, the car thinks there is faults due to a damaged wire/plug and its triggering several faults

DTC give you a guide, not whats actually wrong, its rare for the High pressure pumps to fail, so check all the connections to it are clean tight and no damaged wires

Same for the turbo wiring, again shouldnt be damaged etc etc

key code light = possible damaged antenna, ignore till further issues

Ok, when it stops raining i'll start fiddling..
