Hello!

I changes all 6 glowplugs in March 2022, but the car was still hard to start. So I took Inpa in february 2023, and found those DTC stored.

I changed the glow module and cable yesterday, but still the car is hard to start when its lower than -5 degrees outside, and the DTC still comes back.

 

Are your replacement parts OEM or aftermarket? Have you checked your connector on the MAF? Clean it and ensure your alternator voltage is correct.
