BMW i3 First Service

Another marmite BMW i3 in the workshop for its First Vehicle Check and Pollen Filter replacement Service as it is 2 years old. No range extender (engine) fitted to this model.

Serviced using Genuine BMW Parts & uploading service history to the BMW Database to maintain the manufacturers warranty.

If you are covering little mileage around town, the relatively short range to a charge won’t be much of a problem.

The instant torque from the electric motor is quite addictive under acceleration and the quietness when setting off rather than starting a rattling Diesel engine is extremely pleasant.

Servicing costs are also lower without the fluid & filter replacements. So if you we’re thinking of buying an electric car with the increasing fuel costs, now may be the right time!

We’re all Level 4 Hybrid & EV trained & qualified here at Burch Motor Works so you can be rest assured your electric car is in the right hands!

BMW & MINI FRM – Footwell Module Repair

If your BMW or MINI is suffering from the windows and indicators no longer working. Exterior lights permanently on with red car on ramp symbol on the dashboard when you start the car.

Chances are the eeprom software inside your FRM has become damaged. This can happen during jump starting the vehicle. After battery reconnection. Or connecting to diagnostic equipment.

The dealerships state the FRM unit is then unserviceable and replacement only. A new unit is around £450-600 depending on version, plus fitting & programming to the car!

Fortunately here at Burch Motor Works we have specialist equipment to repair the eeprom in your original FRM unit. Saving the need for a replacement meaning the cost for the complete repair is £72.00 inc vat when installed in the car, that’s more like it!

We repair around 3-4 of these a week as it is a common problem.

So if you’re being told your FRM – Footwell Module requires replacement, please get in touch to see if we can help!

Mini Countryman ECU/ DME Replacement

We hope everyone had a great Christmas & looking forward to the New Year celebrations!

Recently in the workshop with us was this Mini Countryman petrol with the N16 engine.

It had a misfire on Cylinder 2, causing rough running, lack of power & the engine warning light on. The ignition coil & spark plugs had already been replaced by a third party, but the misfire fault was still present. It was suspected the ignition coil had caused a short circuit, damaging the driver inside the Engine ECU/ DME.

With the car in the workshop we scanned the car for fault codes to find Cylinder 2 misfire & ignition circuit monitoring. Proving the description provided to us is correct. Using an oscilloscope we then checked a good ignition wave form on Cylinder 1. As you can see the control signal is at 12 volts. The ECU then pulls the signal to ground for a few milliseconds which charges the ignition coil. Before then releasing the ground providing necessary high voltage to the spark plug.

However as expected, on the Cylinder 2 scope pattern, it is at a constant 12 volts where the driver has been damaged.

Now we have confirmed the fault, the ECU/ DME requires replacement.

A new unit from BMW/ MINI is well over a thousand pounds making a fairly costly repair. Fortunately this Mini was brought to us as we have the specialist equipment tools for us to be able to transfer/ clone the data from the original ECU over to a used donor unit.

With this carried out & all faults cleared. The car now runs and drives as it should – meaning the owner saved over a thousand pounds on the total repair cost.

The total ethos of our business is to save owners money on the maintenance & repair of their vehicles where possible. We thank all that have visited us during 2021 and look forward to looking after your vehicles again in 2022 & beyond

We are now closed for Christmas & New Year

Once again we would like to take the opportunity to thank all of our loyal customers for their custom & support during 2021. The great feedback, and gifts we received during the year is very humbling to us all here, and appreciated so much!
We hope you all have a happy, healthy and trouble free motoring during 2022 ☺️
We will reply to all messages left over the break when we return on Tuesday 4th of January.

Vehicle Technican shortage by 2030

This video on BBC News from The IMI is to highlight the shortage of vehicle technicians currently today and in future years. Importantly a large majority of current technicians are not EV – electric vehicle trained or qualified to work safely on this newer technology.

It’s not fully certain why the motor trade is not an attractive place to the younger generation of today, possibly as manual labour is not promoted in schools, who knows?

Though post brexit and covid Britain seems to be short staffed in every sector at the moment. Fortunately here at Burch Motor Works all our technicians are trained and qualified to IMI Level 4 to work electric vehicle live systems safely.

Along with apprentices and new recruits coming through to fill the shortage in our industry. More about our new guys in the New Year

Thanks for reading & watching.

BMW 120d engine surging under acceleration- fixed

The chap who owns this car booked 6 weeks in advance and waited patiently until we we’re able to take a look at it as he didn’t want anyone else touching it, we appreciate that!
The problem with the car was the engine had a surging sensation under acceleration and intermittently putting the engine light on.

We drove the vehicle to confirm the fault, it was surging under acceleration. Back in the workshop we plugged into the diagnostics to read the fault codes. X2 stored for fuel rail plausibility delivery controlled and x2 for dde control unit internal. The internal control unit faults can be ignored as they do not cause any running faults. However the fuel rail plausibility ones certainly do, so we carried out a test plan on the diagnostics which aid us greatly in the right diagnosis of the fault.

The test plan then ran the engine at different speeds whilst adjusting the fuel rail pressure, to monitor. The results stated that the set points we’re not reached when adjusting the fuel rail pressure and to replace the faulty fuel quantity control valve. This valve sits on the high pressure fuel pump and controls the amount of high pressure fuel that is to be sent to the fuel rail on to the injectors, or returned to the fuel tank, in conjunction with the fuel rail control valve which has a similar function.

So fortunately the diagnostics have made this one easy for us and it’s new part job done I guess.
However it would be foolish to rely on the diagnostics without testing the part ourselves.

We then looked at the graphed live data whilst driving the car to see how the fuel system is behaving. As expected the fuel pressure is fluctuating up & down under acceleration at the same time as it can be felt through the car.
As seen in the graph picture, the red tracer line. Back in the workshop we scoped the activation/ control lines of the fuel quantity control valve which are all correct and plausible, proving the wiring and ecu are all ok. Meaning the diagnostics we’re correct and the valve is faulty.

Fortunately we have a few high pressure fuel pumps for the N47 engine in stock with valves attached. With a replacement fuel quantity control valve fitted, engine adaptations reset & faults cleared.
We road tested the vehicle again with the live data graph which shows a steady fuel delivery as expected, with no more surging under acceleration.

All fixed within a couple of hours and returned to the customer on the same day. It was worth the wait he stated Thanks again to our loyal customers for their patience & custom!

Booking in with us

Just a quick post to mention we are experiencing a high volume of bookings at present, with our bookings being approx. 2 months in advance.

BMW N47 Diesel Fuel System Replacement

Another BMW 1 Series recovered to us not starting. Cranking over but engine not firing. Vehicle in the workshop on the diagnostics it was clear we had a fuel supply problem causing the engine not to start. On the live data we could see no high fuel pressure inside the rail, before going to the injectors. Suspecting high pressure fuel pump failure we removed the fuel rail to inspect for swarf – small metal parts inside the fuel system.
As expected swarf present in the system causing damage.

Once this occurs it is good practice to replace all components on the high pressure fuel system. Along with throughly cleaning the low fuel pressure side – fuel tank, lines and filter replacement.

Unfortunately new fuel system components would write this vehicle off being several thousands of pounds. However we have great suppliers of used parts (or green parts as they’re sugar coated as) that can supply us with complete used kits of the high pressure fuel system, with a 3 month warranty. Allowing us to repair at a fraction of the cost, keeping this car on the road
