Credov's researched list of the 2 faults the BMW 1 Series E88 is known for (2007–2010), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: On the test drive pull hard in 3rd and 4th feeling for stutter or power loss, and note long cold-start cranking.
Why it matters: A failed pump can shut the engine down while driving, and replacement pumps have also failed; repairs commonly run NZ$2,500-$4,500.
What to look for: Lift off at 2,000 to 3,000 rpm and listen for a metallic rattle from the right side of the engine.
Why it matters: Worn bushes let boost run unmanaged and the fix is usually two new turbos; repairs commonly run NZ$2,500-$8,000.
