2014 Mercedes E-Class.
Intermittent issues with instrument cluster. Warning lights would flash on,rev counter would drop off and warning buzzers sound, but car would drive fine.
A code read of the vehicle would bring up a lot of communication errors in all systems. An extensive investigation into the canbus network was required. This network is used by many modules to talk to each other . If this network is corrupted in any way it would log codes in many places as we were seeing. An accurate list of all modules is acquired and we proceed to unplug each of these to see if signal is affected. At this point we don’t know if it’s a module fault or wiring. If wiring is the issue this could be very labour intensive as it runs all round the vehicle.
We at last found a module with an issue. As you can see by our short clip, with the module plugged in the canbus signal was being slowed down, something that we haven’t seen before usually the signal is distorted. With it unplugged the information speeds up as normal.
This Golf was recently in our workshop with aircon issues. It had previously been regassed but had stopped working some weeks later.
We confirmed it was a gas issue and not electrical and performed some tests to discover where the leak was.
It was discovered to be a leaking condenser which is situated at the front of the engine in front of the coolant radiator. We rang customer with prices and got the go-ahead to repair. VW cars usually require quite a bit of dismantling to change condenser and this was no different
With the condenser we always fit new seals to guarantee a good fix ( you don’t want to be stripping this down again!).
With everything fitted we tested system ( high pressure and vacuum) confirmed system was secure and then regassed.
Then returned vehicle to a happy customer
This Fiesta came in with various warning lights illuminated on dash and dash staying on after car switched off.
Various checks performed showed the gauges to be at fault.
New gauges were expensive. We offer a service where we can fit and program a 2nd hand set.
with the cluster in and programmed the car started and ran fine, saving the customer alot of money and time on new parts.
DS3 with airbag light on brought into us from a car sales dealer. Car sold going out and Airbag light is on.
Code read and found several codes for various airbags deployed.
Car may have previously been an accident damaged repair and as such has crash data stored in ecu.
With the correct equipment we can remove the airbag module, strip down and access the eeprom that has the crash data stored. We remove chip from board and read and repair data.
Refit to car and test. Job done quickly and at a fraction of the cost of replacing with new parts.
This vehicle was towed in to us as a non start. With accurate wiring diagrams it became clear that the problems lay with the wiring to the underhood fuse box.
We removed the battery and tray to reveal the engine wiring loom, to find at some point the battery must have leaked and damaged loom.
With all the bad wiring removed and replaced with improved protection from future damage, the vehicle started first time and ran great.
Another happy customer.
2015 Citroen Battery going flat even after journey. Tested at another garage and told it has a discharge, so brought to us.
We performed our tests and found the fault to actually be a non charging fault. The Alternator and wiring were both tested and proved to be good.
As with all PSA group cars this fault can be related to a software issue. With our PSA dealer tool and battery support unit on the vehicle we can scan the car and see if any software updates were available, which there were.
With the download complete the car started charging fine. The customer also stated that the running of the car was much smoother since update.
Another happy customer.

Electric Vehicle Servicing, Maintenance and Repair – A question we are getting asked more and more is…. Do Electric cars still need the same vehicle servicing, maintenance and repair as a regular petrol or diesel car? Well the answer is simple. Yes they do.
For many the worry is how to find the right trained mechanic to fix their car. It is fair to say most mechanics are trained to work with regular internal combustion engines, but don’t have the equipment or staff training to maintain and service electric vehicles. However, just like when you have auto electric faults with your current vehicle, the idea is to find a good auto electrician to deal with these issues. Most experienced car or vehicle electrics specialists will be routinely upskilled themselves in the new requirements and equipment needed to help you.
Again the anwer is simple…Yes they do.. Just like a regular vehicle, an electric car will need to go on for an MOT annually after it is 3 years old. The GOV.UK website can be a source of confusion for drivers as it lists ‘good vehicles powered by electricity’ under vehicles exempt from MOT – however, this does not cover electric cars. So make sure you keep a record or check with your local garage what you will need for your mot
Initially this is always hard to answer, because all vehicles are different and will vary in cost for their servicing and general maintenance. What I have noticed is that with electric motors, and their simplicity and overall low maintenance you could find yourselves with considerably lower maintenance costs saving you literally hundreds over the year.
