CAT aging is a real issue with N53s even at this mileage. Leaking injectors can cause damage to cats + some of these can burn oil especially when revved. Mine does like 1L every 5000km which seems fine according to BMW.

Bmw e91 318d del 2009, cambiata la batteria originale quest' anno.
Pretty smooth repair and haven’t had any issues since.
Rotors and brake pads set you back about 3k every 3 years. Very easy to replace on your own as well.
low miles 10 yr old vehicle means its possible it has the original BMW factory installed battery. Some of those can last 10 years, I had a 2013 bmw 3 series and in 2022, I finally changed the original battery.
I bought my E91 N43B20 with 120.000km in 2017. Now its 2025 and 250.000km I had to replace the timing chain and the NOX sensor once, but other than that I had no problems with the engine. Still the same injectors, ignition coils, high pressure fuel pump etc.
BMW manuals are mid.
Production markings on the side of the filter as shown in the pics above indicate that this is a BMW OEM part. I can’t imagine that Halfords would be installing genuine BMW filters. There’s no way that they changed this.
That never got replaced, the filters still look white after 2-3 years in the cars I work on, this looks 5-10 years old.
That was not replaced in the last 5000mi. If you have an itemized invoice, I would check to see if it states what part was installed.
