BMW 1 Series (2011–)

What's good

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

Great range of diesel and petrol engines.

High-tech yet intuitive nav and media system.

Slick ride and handling.

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.

Mean standard equipment levels.

No hybrid or electric models.

Most advanced safety systems are optional.

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 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 3500 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 £2800 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 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 quoted £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. More so when under load, feels like in wrong gear. No issues when outside these parameters.

6-7-2017: Report of persistent problems with the air conditioniong of 2016 BMW M140i, bought new 9 months previously. Working on the car, the dealer mechanics discovered that the charge air cooler (intercooler) located in the intake manifold had been leaking coolant.

19-9-2017: Owner reported difficulty selecting first gear from stationary in 81,000 mile BMW 1 Series manual diesel 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 outrageous £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.

22-2-2018: Report of plastic parts related to Vanos system of 2011 BMW 116i auto shearing off, falling into engine and into sump at 45,500 miles. BMW dealer says l ubrication system contaminated and requires new engine. Worth checking with a member of http://www.fer.co.uk if it can be rebuilt.

27-2-2018: Report of failure of engine of 2011 BMW 116i at 41,000 miles. Owner quoted £6,000 to repair, which is as much as the car is worth.

30-4-2018: Report of stiff manual gearchange in 2016 BMW 118i Sport. "Quite stiff and clunky when changing into 1st and 2nd gears. The clutch is also relatively heavy which exacerbates the issue."

5-5-2018: Reader with 8 month old 2017 M140i alerted us to a weakness with the radiator reported as follows: There is a well known weakness with the radiator on the B58 engine cars (M140i / M240i only), this does not apply to the stronger N55 powered vehicles. The B58 radiator is particularly flimsy, and prone to bursting from relatively minor stone strikes, losing all the coolant. Replacements cost circa £800 and are not usually covered by warranty, so ignore this post at your peril. BMW themselves have effectively admitted this is a major problem by fitting cars built after December 2017 with two 'Rock Guards'. The prevailing advice is to remove your bumper, and retrofit some mesh to help prevent against Rad punctures.

8-5-2018: Another complaint of stone damage to the radiator and a/c condenser of 12 month old BMW 140i: "S tone penetrated the very flimsy an open front grill and damaged the radiator and I am told also the condenser." Since December 2017 BMW instals, on the front radiator behind the grill, two ‘rock guards’ to protect the radiator from potential damage. Reader's fix in this case is more than £1000.

9-5-2018: Report of paint blisters on bodywork side and rear panels of a 2016 BMW M140i. BMW body shop said stone chips and proceeded to quote £500 to repair a 3mm blister on the side front panel. There is no evidence of a puncture mark and there are now small clusters of blisters developing on the other side and rear panels.

26-9-2018: Report of 2017 BMW 118d 2.0 8-speed automatic at 25,000 miles starting to randomly jerk when driving at 50/60/70mph as if the accelerater was being pushed hard causing he gearbox to kick down, then taking your foot immediately off the accelerator confusing the gearbox - but it is also happening when cruise control is on and foot away from accelerator pedal. Car fully serviced on schedule. Turned out to be a failed (blocked) EGR that was replaced by the dealer under warranty.

1-11-2018: Report of faults with 2017 BMW 135i that include: seat leg extender didn't have the leather fitted correctly, boot not closing 3 times, I-Drive information unit crashing on about 7 occasions, a ripped seat when it was in for repair, although this was fixed.

24-12-2018: Report of timing chain of 2015 BMW 118i 1.5 failing at 39 months old and 33,000 mies.

3-1-2019: Report that lessee of 2017 BMW 140i has had constant problems with the iDrive. Keeps turning off and on when driving and sometimes freezes. BMW dealer replaced the iDrive unit for another new one but it has been back in twice since then and they are now saying it could be owner's iPhone's fault. But he have purposely kept his iPhone disconnected for a while and even tried a new iPhone in the car and it is still doing it.

23-1-2019: Report of failure of engine of BMW 1 Series diesel at 100,000 miles. Lost power suddenly.T wo specialist diesel garages have looked at it and have indicated that it requires High Pressure fuel pump, 4 injectors, fuel rail and sensors, fuel pipes if required and remove fuel tank. The estimated cost will be between £3000 and £4000. He did let the fuel level drop low and its suggested that debris from the tank or otherwise contaminated diesel has been the reason for the problem.

6-3-2019: Report of dash message: "Drivetrain - Continue the journey at a moderate speed. Full performance not available. Have the problem checked by Service" in 2013 BMW 118i M Sport at 31,500 Miles with Full Service history. Car went into ‘limp’ mode. It would only do this on a cold start and owner could stop, turn the engine off and back on again and this would remove the error message until the next morning. As this persisted to happen, owner took car to a local BMW specialist who replaced the VANOS solenoid valve and oil filter. The next morning, again on a cold start, the message appeared again after driving half a mile. Owner returned the car to the specialist who diagnosed the problem as a software matter and so updated the current to the latest over the course of 2 hours. This wiped clean all the settings saved on the iDrive and they did another cold start later that day and found no fault. However, when using the car the next morning the error message has returned. Owner told the next step is to remove the cylinder head to investigate further.

10-3-2019: Report of engine failure of September 2015 BMW 118i 1.5 at 34,000 miles. Piston collapsed. BWW dealer initially quoting £10k to replace the engine before the owner takes appropriate legal action.

27-4-2019: Buyer looking at 2016 BMW 118i with B38 1499cc 3-cylinder engine found that at 20,000 miles it had a new cylinder head fitted. See also: 10-3-2019, 24-12-2018. (Reports of earlier 118i engine failures were of the previous 4-cylinder N48 engine.)

29-5-2019: 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.

12-6-2019: Report of infotainment screen going blank in 2013 BMW 116i automatic. Will only show BMW logo. Dealer says common problem. Needs to be rebooted.

6-7-2019: Rattling timing chain reported in N13 engine of 2013 BMW 116i F20 at 66,000 miles. Specialist quoted £795 to change chain and tensioner.

30-8-2019: Report that on a 50,000 mile 2014 BMW M135i, the 'rear offside drive shaft joint constant velocity boot' was found to be leaking grease and requires repair ASAP. Unfortunately this seal can't be replaced as the individual part is not manufactured and it therefore requires a new drive shaft at a cost of over £1,200 to supply and fit. Googling <BMW 1-Series driveshaft CV boots> and found a lot of 1-Series driveshaft CV boots at prices from £30 - £70.
