Hmm
N53 revised version 6 cylinder 525i petrol with Valvetronic can suffer bore ovalisation at moderately high mileage (90k) due to dribbling injectors. Oil consumption can rise to 500 miles a litre. Only remedy is a new short engine.
15-4-2014: Worldwide recall of 489,000 BMW cars with six-cylinder 2.5 and 3.0 litre petrol engines of which less than 3,000 are in the UK. These are: N51 (1991-1995), N52 (from 2005) and the N55 6-cylinder petrol turbo (from 2009). The screws for the housing of the adjustment unit of the variable camshaft timing (Vanos) for the intake and exhaust camshafts could potentially become loose or break. An engine warning lamp ‘should ’ appear in such circumstances, but if drivers experience any loss of power they should contact their BMW dealer immediately.
