BMW 1 Series (2011–)

Last updated 13 January 2018

What's good

Five Star Euro NCAP result: 91% adult safety; 83% child safety; 63% pedestrian safety; 86% safety assist.

What to watch out for

The sub 100g/km, 116d Efficient Dynamics model was not available until March 2012. The models released in September 2011 are the Sport and Urban designs - neither had the ED engine and so emit 117g/km.

Warning about the 'Mobile Application Preparation (6NR)' option at £130. This is ESSENTIAL because it enables the iPhone ‘BMW Connected Drive’ app, including web radio. BMW UK officially doesn’t or won’t support a retrofit of 6NR (though 'fixes' are available via idependent specialists).

Drains to bulkhead vent wells prone to getting blocked with leaves, making wiring in the area vulnerable to moisture ingress. Make sure you keep the drains clear both sides.

16-7-2013: Parts shortage for front suspension of M135i reported. One 135i off the road for at least 5 weeks following pothole damage.

10-3-2014: Report of brakes failing completely on 18k mile 2014/64 BMW 116i. Brake pedal went hard.

1-7-2015: Problems reported with 2013 F20 114i over 15k miles: front windscreen washers not working (twice) and Amber Warning--Drivetrain.

1-4-2016: Report of clutch/DMF seizing on 2015 BMW 118d at 12,000 miles, mainly motorway. Replaced FoC under warranty, but driver's driving blamed.

5-4-2016: Report of "Quality Enhancement” programme to F20 1-Series involving fitting a new cap to the brake fluid reservoir because water can through the standard cap and contaminate the brake fluid. When a reader's 2014/64 BMW 120d xDrive M-Sport with 13,500 miles was being checked the dealer found water in the braking system meaning the car also requires a new DSC hydro unit and the system draining and refilling. Unfortunately, the necessary parts are not available until 30th June 2016.

21-7-2016: Intermittent failure of instrument display of 3,500 mile 2015/65 BMW 1-Series. Resets by switching off ignition and re-starting, but then fails again. Suspect a bad earth somewhere.

3-8-2016: Report of clutch failing on 2011 BMW 1-Series a month after purchase at 16k miles in November 2015. Clutch replaced under warranty, then failed again at 22k miles in July 2016.

17-8-2016: Report of timing chain of N47 2013 BMW 116d being replaced under warranty in 2015. Owner now worried that will still suffer from the same infamous N47 tensioner problem.

24-12-2016: Report of red lights appearing on dash of 2012 BMW 118i at 52k miles. BMW dealer charged £160 for electronic diagnosis, but would not tell the customer what the diagnosis was, citing "BMW copyright". Would only state that £2,800 of parts were needed. Later transpired that the plastic timing chein tensioners had broken up and bits fallen into the sump, so the £2,800 was to replace the timing chain and tensioner, someting the BMW dealer seemed to want to keep secret.

6-2-2017: Report of 2013 BMW 118i developing timing chain issue at 25,000 miles and 6 months out of BMW warranty. Unfortunately, missed a service by 2 months where the issue (lack of oil?) might have been picked up and corrected.

28-4-2017: Report that 2010 118i with N43 engine needed a new engine at 59,000 miles. Fitted FoC.

29-4-2017: Report of catalytic converter heat shield on 27,000 mile 2013 BMW 116i coming loose. BMW dealer demanded £67 for "inspection" and quotyed £835.93 to replace it.

22-5-2017: Report of noticeable change in engine noise and slight vibration in steering wheel between 1800 and 2000 revs in late 2015 BMW 118i 3-cylinder, auto. 1495 cc. More so when under load, feels like in wrong gear. No issues when outside these parameters. When PARKED and revs slowly increased issue still shows again at mentioned figures. Has been like it since new. Dealer and BMW notified but still waiting for answers. Seems strange because there is a known issue with the crankshaft berarings of this engine.

6-7-2017: Report of persistent problems with the air conditioniong of 2016 BMW M140i, bought new 9 months previously. Owner took car back to supplying dealer with an ultimatum to fix the car or he would reject it. Working on the car, the dealer mechanics discovered that the charge air cooler (intercooler) located in the intake manifold had been leaking coolant. Dealer sent the owner a video (as is current BMW practise). Cylinder head intake ports and valves are caked with dried coolant residue. Dealer is proposing to clean the cylinder head and replace the faulty parts (as well as fix the air-conditioning), but owner is worried about valve seats and wider long-term damage that will have been done to the engine due to ingestion of water vapour over an extended period. Suggested he write a letter to the dealer principal of the supplying dealer stating that the car was faulty as supplied and that he wishes to reject it, citing the ruling in Clegg v Olle Andersson, House of Lords, 2003. But if the supplying dealer will offer an unconditional 5 year warranty on the engine after the repair he would be prepared to accept the car back in a repaired state. Send it by Post Office Special Delivery, keep a copy, and staple the certificate of posting to the copy so that it becomes a matter of record.

19-9-2017: Owner reported difficulty selecting first gear from stationary in 81,000 mile BMW 1-Seried manual diese XDrive. The gear can be eventually selected after 2-3 attempts. It is not like this all the time and acts perfectly 8/10 times. The other gears (including reverse) are fine. Suspect dual mass flywheel.

18-10-2017: Rattle reported from rear exhaust system of BMW M140i, apparently from the isolating valve in the nearside exhaust pipe.

28-11-2017: Completely outrageious £276 quoted for oil and filter change for a BMW 118i.

13-1-2018: Complaint of resonance at 65-70mph in BMW M140i. Maye the same rear silencer box issue as 18-10-2017.


15-4-2014: Worldwide recall of 489,000 cars with six-cylinder petrol engines of which less than 3,000 are in the UK. This includes 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.
