Greetings,

On my Renault Scenic III 1.6 96 Kw 2014, the service light came on and two errors:
• Check anti-pollution system
• Check injection system.

I don't notice any change in the car's handling and the car's power itself is normal. The car has 125,000 km and a major service was done 1 month ago (all filters, oil, micro belt, water pump, etc.)

The only thing I noticed while driving is that when I step on the gas, I hear some kind of air leaking from the right side of the engine. And the car every 20 seconds when idling, it is sound like if getting some kind of extra gas.

After connecting the tester, they show me errors:

DF1012 (Consistent Multiplex Signals For CC/SL, The Data Supplied to the Cr)
DF 301 (Inlet air circuit, Signal Outside Upper Limit)

And 3 errors on the UPC:
DF109 (Battery Worn, Performance Down or Incorrect Operation)
DF 102 (Fan Unit Control Circuit 2, Open Circuit or Short Circuit to Earth)
DF083 (Stop and Start Module Circuit, Invalid)

Thanks for the advice,
Anze

Ok so there is a big chance it could all be related to a bad battery mate

Take it all these issues are new?
A duff battery can cause the incorrect voltage to several modules/ECU bcm etc causing things to work incorrect and also show codes that are not really correct if that makes any sense


The fact it's showing a battery issue tells you thats the first thing to do

But please make sure get the correct battery for the car


If you need help getting the correct battery send the year engine size etc and I'll happily show you the cheapest battery that will work for your application

After fitting clear the ECU drive the car and scan again
