BMW E87 ignition coil faults

Coil failure is common on the 1 Series. Replacing one coil is usually not enough, because the old coils easily fail soon after. Therefore it is worth replacing all the coils at once. Some 116i models were part of the importer's service campaign, in which all the coils were replaced.

1. Remove the fresh air filter and the plenum cover in front of the windscreen (8 mm socket). 2. Open the cover and remove the plastic cover on top of the engine (three 6 mm hex screws) and the oil filler cap. 3. Replace the coil. The plastics are brittle in frost, so warm up the car before the job.

Genuine BMW parts have a 2-year warranty. Ask the workshop for a receipt that shows which cylinder's coil was replaced. If the cylinder can be shown, the warranty also covers the replacement work, even if you replaced the coil yourself.
