poor performance due to missing readings? was created by cenk
Hi,
I have a 2011 Citroen C4 1.6 VTI auto, and I'm in trouble with my car, there is a lack of power, it feels more when going uphill, slowing down too much, straight road acceleration is not satisfactory, fuel consumption is also seems high, i took my car to the authorized technical service, and gives the following error codes;

BVA_AT8 Section : U1003
MEV17_4_2 Section : U2000, U2118, P0420
ABS Section : C1510, U2000, U1318

also torque app charts plugin shows some reading are missing, could this be the source of the problem?
screenshot added below.

missing readings:
barometric pressure
absolute engine load
intake manifold pressure
relative throttle position

PS: There's a non-priority issue: I don't know if it's related with other issues but steering is hard also.
