A couple of BMW i3s recently visiting the workshop

First i3 was dropped off to us as the car would not charge displaying a fault when charging, with only 1 mile remaining they were glad to make it to us.

Upon investigation we found the faults stored showed no air conditioning gas pressure along with high voltage charging faults. The importance of the air con system working on electric and hybrid vehicles as it not only cools the cabin, it is also plumbed in to cool the high voltage battery packs. So without the air con working, the vehicle will not charge to prevent possible overheating of the battery.

With no air con gas present in the system. We carried out a nitrogen gas test to locate the leak from the condenser at the front. With the condenser replaced and air con system re-gassed with the newer 1234yf gas, all faults were cleared. The vehicle then left to charge overnight to full correctly. Road tested and returned to the customer

Second i3 was much more straight forward. Full service as this version had the range extender (or an engine if you don’t like stupid bmw terminology).

Engine oil, pollen filter, air filter and spark plugs replaced, with a brake fluid change.

Service history updated on the BMW Database then uploaded on to the iDrive, same as the dealerships! Job done

All our Technicians are IMI Level 4 Hybrid & Electric Vehicle trained & qualified so you can be sure your vehicle is in safe and capable hands. You’ll be shocked by what we can do. More information about how we can help with your electric and hybrid cars.

Forte – Air Con Power Clean Bacterial and Odour removal machine

Forte – Air Con Power Clean Bacterial and Odour removal machine
This little machine is a great aid this time of year to remove the bacteria and odours sitting within your cars heating system, along with the complete cabin.

The cleaning machine is placed inside your cars footwell, heating system set to medium warmth and fan speed, closed recirculate loop for 15 minutes. This allows the anti-bacterial vapour from the machine to be sucked up the lower vents into the heating system, then blown out the front vents to cleanse the cabin.

This time of year with the air conditioning in use, the damp air con evaporator can have bacteria build up when the car is parked. Then blown into your face over and over when the car is driven… nice! Which is why we are offering the Forte – Air Con Power Clean Procedure at a special offer price of only £28.00 inc vat, until the end of August. (Normally £39 inc vat).

You’re welcome to have this treatment separately or add on to an existing booking with us over the summer! Also – if your air conditioning system is not blowing cold, we can investigate the cause and carry out Regassing where necessary. For more information please visit our Air conditioning cleaning page

Keep safe this Summer – Burch Motor Works

Cononavirus Update: Garage opening and MOT update

We are still currently open and operating our contactless service, as per our last post and on our website. This is working well to keep us operational and as safe as possible.

  • Our reception is closed, no waiting appointments or loan cars are permitted at present.
  • Some of our parts suppliers are down on staff meaning repairs can take longer if required. Along with all BMW dealerships closing, and the local Hendy group. So we will not be able to obtain parts from these at present.
  • The government have just given a 6 month extension to light vehicles with an MOT after the 30th of March. This is to allow vehicle owners in full isolation or do not want to risk contact the flexibility to carry out test further down the line in the year. However it does state you will need to make sure the vehicle is roadworthy so it would be advised to carry out the MOT when it is due to make sure the vehicle is safe and legal.

We have had advice from the government/ DVSA in the pictures below.

Thank you to everyone for being sensible and understanding with the current situation. If you have any questions, please ask. Stay safe.

Coronavirus News

Sorry to add to the Coronavirus content on your across the media.

We just want to reassure our customers we are open as usual and doing our best to prevent the spread of the virus by constantly anti-bac cleaning our contact areas. Reception door handle, counter. Customers keys, car steering wheel, gear shift, and handles. We are also wearing our usual protective gloves but only one set per vehicle, then in the bin.

If customers are still concerned about contact when visiting, we have a drop off and collection procedure that allows customers to drop keys off and collect again outside of opening hours. Please call us for this procedure.

I hope this may reassure some who are partly self isolating. Not sure if the police will accept the Coronavirus as an excuse for the cars MOT being expired!

Used BMW 8 Speed Auto Transmission Replacement

A recent repair with us, BMW F10 5 Series with a very broken 8 Speed Auto Transmission. Only course of action was to send away for reconditioning or replacement. A new transmission was £12k, recon was £3k. With the age and mileage of these models getting on a bit now, the only sensible option without writing the car off was to source and replace with a used transmission.

However, with these EGS ZF 8HP Transmissions, BMW have kindly placed the Immobiliser (EWS) inside the transmission control unit. Meaning if you fit a used box to the car, it will not go into gear/ work at all. Even with genuine bmw software it will not overwrite the immobiliser code.
Which is why here at Burch Motor Works we have the genuine bmw software and various aftermarket software programs to allow us to work around these issues.

We reset the immobiliser code to a factory state using our aftermarket software, then programmed the transmission to the vehicle…. take that BMW ?
Finishing off by replacing the transmission fluid & filter pan. Road tested vehicle now driving like the ultimate driving machine again… at a fraction of the cost!

We have all the gear, and hopefully some idea to save you money on your repairs… you’re welcome ?

Finding a strange fault

We always appreciate the feedback we receive from our customers. Thank you for taking the time from your day to review us! It makes it more worth while after finding a strange fault.

After a Mini was recovered to us with a seized alternator. This was a job to be carried out as soon as we could, as it was not booked in. The Battery was flat, we put the battery on charge for a few hours. We replaced the alternator and drive belt, then refitted the battery. Started the engine, now running fine with battery charging correctly.

However several systems were not working correctly afterwards such as dash lights, sounds and radio displaying disabled with no function. A full diagnostic test showed several control units on the K- Body Bus had no communication. A quick check of the main fuses for these systems showed all fuses are ok. We then called the customer explaining this issue. Fortunately they were honest stating this had been an intermittent fault in the past. With the fault now present, they were happy for us to investigate to locate & rectify the fault.

To start, we located the wiring diagram for the K- Body Bus with all control units listed on the bus. A quick test to see if one unit is bringing the system down is removing fuses/ power to each unit to see if the system returns on the diagnostics. Unfortunately this was unsuccessful with no change with fuses removed. The customer had mentioned the bc1/ general module control unit was suspected to be at fault in the past. With this in mind we headed to this first. Interchanged the unit with a used one we keep for testing. This made no change. With these easy tests made, we then needed to get deeper to check the K- Body bus.

After a mid update with the customer, they mentioned the fault had been intermittent and the vehicle had an aftermarket Bluetooth kit that had been removed. (Or so it should have been).
We checked the K- Body bus wire at the bc1 connector. It read 1.17 volts, which is very low as the bus should be battery voltage around 12 volts. Something was shorting to earth bringing down the voltage on the bus.

With the information from the customer, the next logical step was to check the radio where the Bluetooth kit ‘was’ fitted.
Moved radio out to find an additional wiring loom still present for the Bluetooth kit, but the unit had just been removed. We then disconnected the loom from the back of the radio wiring and BOOM, K-Body bus went back to 12 volts at the bc1 wire, as it should be. Removed the loom and refitted original wiring to radio. Refitted all parts correctly. Diagnostic check now shows communication to all units correctly with no faults. Dash lights, sounds and radio now working correctly. Fault rectified ?

We usually find with most electrical faults or battery drains, they are caused by aftermarket systems being fitted. With the help of the customer it allowed us to locate the fault faster!
It is always nice to be appreciated for our work! We’re here to help!

 

Swirl Flap Removal & on Car DPF Cleaning

This customer was glad they returned their X5 back to us for an MOT, intake swirl flap removal & DPF Forte Power Clean.

During a service a few months ago. We upload the service history from the BMW Database into the vehicles I-Drive. At the same time we always check the vehicle fault codes free of charge during the service and report to the customer if recommended attention is required.

On this occasion we noticed engine fault codes for swirl flap movement & DPF high back pressure. The Diesel N47 engine in this model is prone to the intake swirl flaps becoming stiff in movement from carbon build up or worse wearing on the shaft causing them to fall off going into the engine combustion cylinders. Causing large expensive damage writing off the engine and in some cases the vehicle!

As a result of engine fault codes stored being present. It can prevent the engine ecu from regenerating the DPF – Diesel Particulate Filter of its own accord, causing it to block over time.
So we recommended on their next visit we check/ remove the intake swirl flaps and carry out a Forte DPF Power Clean, the most cost effective method to clean/ repair your a DPF.

As you can see from the pictures, the customer was very lucky. Cylinder 2 swirl flap had fallen off completely and luckily was too large to pass the intake valves and was sat in the intake port. Cylinder 4 was ready to fall off with the other two loose!

So we removed all swirl flaps, rod & blanked the rod hole with a bung. Along with manually removing as much carbon build up as possible.
For regular maintenance we recommend the Forte Intake System Power Clean which would soften & break down this carbon build up on the engine intake manifold and valves.
Once rebuilt we carried out the Forte DPF Power Clean to bring the exhaust back pressure levels low, well within spec so it will now regenerate of its own accord once again.

So you can see the benefits of using a Specalist Garage with experience, expertise & equipment to maintain your BMW & MINI with cost effective solutions!
