Your BMW’s MOT test is a safety inspection and is undertaken to ensure your car is safe to drive. New cars have to wait 3 years before one is due.

Here at BNTEC we understand it can make you a little nervous but our MOT testers are on hand to help make it as simple as possible for you and explain any advisory items included in the test result.

The MOT test on your BMW takes around one hour and we offer a While-U-Wait service. We also offer to pick-up and drop-off service from your home or place of work.

It is a legal requirement to have your BMW MOT’d. Currently vehicles aged 3 years or over must be tested every year before the previous one expires. You may bring your car in up to 30 days before your old MOT runs out without losing any days.

For further information about MOTs please visit the VOSA website:

Mini Wheel AlignmentBMW 4 Wheel Alignment

You may have noticed our roads around Hull & surrounding areas are full of potholes and speed bumps. Sometimes it’s impossible to avoid them; they cause wear and tear and damage to your tyres, suspension and frequently knock out the correct alignment of your BMW’s wheels.

You should have your wheel alignment checked if you are experiencing uneven tyre wear, pulling to the left or right, poor handling or your steering wheel is off-center, also when any steering or suspension component has been changed.

This includes all adjustable front/rear end settings to within BMW manufacturers range.

BMW Fleet / Lease Serving

A lot of BMW manufacturer literature creates the impression that you have to use a BMW main dealer to service company car this is simply not true. Current EU Legislation, means that as long as we use genuine or approved BMW manufacturer parts and oils during the service you are not breaking any terms of your contract and your new BMW warranty is guaranteed.

We will also reset your dash service lights and stamp your BMW service book..

Mini AirconBMW Air Con Servicing

Most modern BMW cars are fitted with an air conditioning, the manufactures state that the system will naturally loses up to 15% of its refrigerant gas every year. A poorly performing car aircon system can cause a build-up of bacteria and other microbes growing inside the evaporator ducts causing a bad smell and sometimes an allergic reaction.


  • It is recommended you service your aircon system at least every two year
  • Protect yourself from bad smells, germs and hay fever allergies
  • Improve passenger comfort
  • Save £££’s in potential repair bills

Mini Vehicle InspectionBMW Vehicle Inspection

Buying a new BMW car can turn out to be very expensive and stressful nightmare. We offer this service for customers who would like an independent condition report prior to purchasing a BMW or when the warranty on their existing car is about to run out. Our full vehicle inspections can:

  • Give you peace of mind before your BMW purchase
  • Help save money when negotiating the price of your new BMW
  • Make the most of the garage’s warranty before it runs out

We will carry out a comprehensive vehicle inspection and report on any defects or potential wear items and advise on any repairs required in the near future.

Mini TechnologyBMW Technology

Our diagnostic equipment offering full fault code read and re-set, including – resetting of all service lights, engine management light, SRS lights, ABS & traction control faults, electronic control unit procedures, clearing and setting of adaptation values, full investigation capability of ECU and transmission control module, real-time reading of all BMW dynamic data.

Mini Quality PartsBMW Quality Parts

As one of the biggest independent garages in the country, to maintain the quality of your car and warranty, we have access to the same BMW parts your dealer does as well as thousands of parts from alternative brands many of which are already household names.

Original Equipment and After market Parts
Most Vehicle Manufacturers don’t make parts, they design them and then award a contract to a large manufacturer to produce them, be put in their branded boxes and sold as genuine products. We have access to some of these manufacturers meaningthat we can offer exactly the same quality parts at substantially lower prices.

Since the advent of the European Car Block Exemption Laws we are now able to offer a wide range of quality, Vehicle Manufacturer Approved parts by some of the best known manufacturers in the world Bosh, Lucas, Continental, . These quality parts are commonly known as OEM original equipment manufacturer and provide fantastic opportunities to substantially reduce service and repair costs whilst maintaining the quality of your vehicle even, if it is still in its initial warranty period.

Mini DieselBMW Diesel ParticuDPFs reduce diesel soot emissions by 80% but they’re not suitable for everyone.

The exhaust emissions standards for new cars have effectively required fitment of aDPF in the exhaust of diesel cars since 2009 when the ‘Euro 5′ standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but the technology’s not without problems – AA patrols are regularly called to cars with the particulate filter warning light on indicating a partial blockage of the filter.

Even if your driving isn’t mainly urban/stop-start, changes to driving style may be required to get maximum benefit from these systems.

If you’re buying a new car and plan to use it mainly for town-based, stop/start driving it would be wise to avoid a diesel car fitted with a Diesel Particulate Filter (DPF) because of the possible hassle of incomplete ‘DPF regeneration’.

How do Diesel Particulate Filters work?

Diesel Particulate filters (DPF) or ‘traps’ do just that, they catch bits of soot in the exhaust.  As with any filter (think of the bag in your vacuum cleaner) they have to be emptied regularly to maintain performance. For a DPF this process is called ‘regeneration’ – the collected soot is burnt off at high temperature to leave only a tiny ash residue.

Regeneration is either passive or active

Passive regeneration
Passive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don’t get this sort of use car manufacturers have to design-in ‘active’ regeneration where the engine management computer (ECU) takes control of the process.

Active regeneration
When the soot loading in the filter reaches a set limit (about 45%) the ECU can make small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration. If the journey is a bit stop/start the regeneration may not complete and the warning light will come on to show that the filter is partially blocked.

It should be possible to start a complete regeneration and clear the warning light by driving for 10 minutes or so at speeds greater than 40mph.

If you ignore the warning light and keep driving in a relatively slow, stop/start pattern soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will have to take the car to a dealer for regeneration.

Expensive repairs

If you continue to ignore warnings and soot loading keeps increasing then the most likely outcome will be that you will have to get a new DPF costing around £1000.
