Hey guys. My car is A4 2016 2.0tdi 140kw. Ive got a problem. I turn on ignition and i get all sorts of problems, traction control problem, tyre pressure problem, safety system problem, drive system fault, engine check etc. Then i turn it on, car goes on limp mode says drive system fault. I figured battery, but i turned on scan tool and it says that voltage is OK. But I dont know if u can trust scan tool with battery. Anyways when i scanned the car i got fault on Turbo Boost Sensor. Can that be the problem or should i check the battery first? Thanks guys.
 
have battery tested first, voltage alone doesn't mean the battery holds a charge.
 
Thanks! Its probably unrelated but i have FM Bluetooth transmitter that connects to cig lighter. It shows voltage And it showed 10.7 today. Usually i was above 12. But I need to test it with proper tool. Can that turbo sensor issue be related to faulty battery?
 
nope, that'll be something else... unless that was the start of the problem... 9 out of 10 times this is related to boost... could be either over- or underboost.
 
turbo-actuator or boostpipe leak, apart from that you need t get your battery tested... it might need replacing and coded in... replace like for like.
