Engine oil

BMW handbooks only list oils for topping up and leave the oil change to a qualified workshop; the list depends on the handbook edition. 2 Series Active Tourer F45 handbook (II/17): BMW Longlife-04, or Longlife-12 FE for certain diesels only, in SAE 0W-40, 0W-30, 5W-40 or 5W-30; otherwise up to 1 litre of ACEA C3. F45 facelift handbook (VI/19): BMW Longlife-04 or -12 FE — the handbook adds that Longlife-12 FE is not suitable for the 25d, 35d, 40d and 50d diesels — in SAE 0W-30, 5W-30, 0W-40 or 5W-40 (0W-20 and 5W-20 are excluded for diesels); otherwise up to 1 litre of ACEA C2 or C3. 1 Series F40 handbook (II/22): BMW Longlife-04 or -12 FE, in SAE 0W-30, 5W-30, 0W-40 or 5W-40; otherwise up to 1 litre of ACEA C2 or C3. No additives. Quantity published by BMW: 4.8 l for the B37C15U1 of the F40 116d (oil-change quantity). No quantity is sourced here for other installations.

Timing drive

Chain, according to ADAC. BMW’s training documents on the modular family explain that, because the crankcase is shared by petrol and diesel engines, the timing drive is two-part: a lower chain drives an intermediate shaft, which on the diesels also drives the high-pressure pump, and an upper chain drives the camshafts. The sources consulted give no replacement interval.

Recall campaign

In October 2018 BMW expanded a technical campaign on the EGR module of certain diesels: glycol leaking from the EGR cooler, combined with soot deposits, can create smouldering particles and, very rarely, melt the intake manifold or cause a fire. About 1.6 million vehicles worldwide, built August 2010 to August 2017, with periods varying by model; the module is checked and faulty parts replaced. BMW does not list engine codes, so have the VIN checked.
