Two of BMW’s most popular diesel engines are now available in the 1 Series Convertible. BMW’s most economical four-cylinder diesel engine ever and the award-winning twin–turbocharged unit are a timely introduction for new car buyers seeking open-air motoring but are worried about rising fuel costs.

The 118d Convertible is powered by a 1,995cc single turbocharged engine producing 143hp and 300Nm of torque. This results in a zero to 62mph time of 9.5 seconds and a top speed of 129mph. Most impressive though is the 118d Convertible’s ability to record a combined consumption figure of 57.6mpg and CO2 emissions of 129g/km. This means the vehicle, courtesy of BMW’s EfficientDynamics technologies, is the most economical and least polluting convertible car in its class.

For those customers demanding greater performance the 123d Convertible comes with a 1,995cc twin-turbocharged engine producing 204hp and 400Nm of torque. This propels the 123d Convertible from zero to 62mph in 7.5 seconds before going on to a top speed of 143mph. It too comes with all the facets of EfficientDynamics and thus records a combined consumption figure of 52.3mpg and CO2 emissions of 144g/km – again the lowest compared to any competitor product.

Both models come as standard with a six-speed manual gearbox. The BMW 118d Convertible is priced from £23,660 OTR, while the BMW 123d Convertible starts at £28,105 OTR.

December 2010

BMW 1 Series Coupé and Convertible ranges received a number significant modifications and upgrades that make them more desirable and efficient. Both models differentiate themselves from previous incarnations by way of a new front bumper with redesigned fog lights and redesigned Halogen headlights with an ‘eyebrow’ element. When Xenon headlights are specified this ‘eyebrow element features an LED illuminated light bar. At the rear the headlights have also been changed with a more detailed appearance.

However, the greatest change to ES, SE and Sport models is that they now come fitted with an Aero Curtain – a feature that channels the airflow around the front of the car to reduce aerodynamic drag, thereby increasing efficiency. Wheel arches are one of the main areas of aerodynamic drag and the Aero Curtain is BMW’s innovative solution to reduce this inefficiency. Derived from race technology, air is routed into two ducts in the front apron which then flows out of a narrow opening at high speed in the wheelarch. This jet of air effectively covers the side of the front wheels like a curtain and thus reduces turbulence.

As a result, emissions have been lowered throughout the range, with the 118d now rated at only 118g/km, while all 2.0-litre petrol versions have emissions of 155g/km or below.

As with all BMWs, the 1 Series Coupé and Convertible also come with a raft of other EfficientDynamics measures: Auto Start-Stop is fitted to all petrol and diesel models (excluding versions with automatic transmission), while Diesel Particulate Filters, Brake Energy Regeneration, Electric Power Steering (excluding 135i), Intelligent Alternator Control and Optimum Shift Indicator for manual models are all standard throughout the range.

All BMW 1 Series Coupé and Convertible ES models come as standard with 16-inch alloy wheels, Dynamic Stability Control, Halogen headlights, MP3 playback capability and rear seat easy access system. Sport models have as standard 17-inch star-spoke alloy wheels, Sport multi-function leather steering wheel and front Sport seats – almost £1,200 worth of equipment that is currently offered for no additional cost over an ES model. SE models get rear Park Distance Control (PDC), front fog lights and automatic air conditioning with two-zone control.

All M Sport models, in addition to SE models, come with 17-inch light double-spoke style alloy wheels, door sill finishers with M designation, chrome front exterior trim, high-gloss Shadowline window surrounds, M aerodynamic bodystyling, M Sport suspension, Run-flat tyres, Sport seats and M Sport multi-function leather steering wheel.

BMW 135i M Sport versions add twin black-chrome exhaust tailpipes, a unique M aerodynamic package, M Sport suspension with 135i-specific calibration, hydraulic power-assisted steering, rear spoiler and up-rated high-performance braking system. The new BMW 1 Series Coupé and Convertible go on sale March 2011, with prices starting from £24,245 for the 118i ES Convertible.

From Spring 2013 this system will be available in all BMW 6 Series models, the new BMW 1 Series and in the BMW X3.

What to watch out for

01-01-0001:

22-01-2011:

Repeated coil and injector problems on 4-cylinder petrol engines from 2007.

12-06-2016:

Report of new timing chain needed on 2008 BMW 120d N47 M Sport convertible at 42k miles. Too old for free replacement, but BMW reduced the £2,500 cost to £1,300.

07-12-2016:

2008 BMW 118i convertible with 17k miles left standing in a garage for a year after which it required four new injectors at £250 each, plus a new ECU at £900. Dealer told customer its diagnostics could not determine which injector was faulty or even if the faut was with the ECU.

08-09-2018:

Report of all four ABS sensors of 2010 BMW E83 125i M Sport convertible failing before car reached 30,000 miles.

29-05-2019:

Report of series of problems with 2013 BMW 118i cabrio bought from an independent dealer in July 2018. Has the N43 2.0L engine and autobox and had 28K miles up when purchased. Full BMW SH and one owner. AA certified used programme. She purchased a 3-year WMS warranty as well. Within a week of purchase it needed a new cam sensor, which was covered under the warranty. In late August 2018 it went in to a BMW dealer with warning msg re brakes. A new brake servo was diagnosed at a cost of £1,035 but reduced to £850. WMS would only cover £554 but in the end the original supplying dealer paid the bill in full. On 27th November, 2018 the same warning msg came up and the local BMW dealer first of all said that it needed a new engine, but then concluded that it required a new vacuum pump. The BMW dealer said they had taken the oil filter out and found metallic contamination but didn't change the oil or the filter. The cost of the vacuum pump is unknown but BMW covered the replacement in full. Then on 18th April 2019 at 34k miles, a low oil pressure warning came up on the dash. BMW dealer prescribed a new engine which is currently being fitted and the warranty company will pay £9,200 of the £10,500 bill, the difference being due to BMW's high labour rates compared to the average that WMS will cover.

What does the BMW 1 Series Convertible (2008 – 2014) cost?
