A few notes about the BMW 1-series (2004-2011 ):
For this particular series, BMW list only one or two specifications for engine oil which should be covered by Comma Longlife 5W30 or Syner Z 5W30 for the later cars.
With service intervals of up to 18,500 miles, supplying the customer with a top up pack and reminding them that they should be checking the engine oil regularly (see handbook for guidance) might also be prudent here. A quick check before you change might be a good way of reinforcing the importance of top up to the customer. Combined with longer service intervals and the increased use of sensitive components like turbochargers, a smaller sump size makes checking your oil more critical than ever before.
BMW use one or two specifications for brake fluid for the 1-series and again you need to identify which product is suitable for the vehicle you are servicing.
Most people don’t think of brake fluid as a service item however, as with many manufacturers, BMW specify a change interval of 24 months for this 3 series. Brake fluid degrades over time by absorbing water from the atmosphere (even when it is apparently sealed inside the system) which lowers its boiling point. Boiling point is a critical factor in brake fluid performance because of the amount of heat generated during braking. If the boiling point of the fluid is too low then continuous or hard braking may cause the brake fluid to vapourise which in turn can result in a loss of hydraulic pressure within the system (i.e. your brakes don’t work when you most need them to). The message here is that brake fluid is a safety critical item so check and change when specified – don’t assume that it will just be OK.
Power Steering Fluid
BMW use one or two specifications for power steering fluid for the 1 series and again you need to identify which product is suitable for the vehicle you are servicing.
Xstream G48 is the recommended product for the 1 series, as it is for all recent BMW vehicles.
For this particular 1 series, BMW uses a range of transmissions that includes mostly manuals but also some automatic alternatives. As well as different fluid requirements, change intervals and capacities will vary depending on the type of transmission so we would advise you to consult the handbook to ensure that you get the right product for the vehicle you are servicing.
