VW Golf aircon

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

2013 Ford Fiesta dash fault

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.

This 1st tool allows us to program the immobiliser and keys. Also adjust the milage.
This 2nd tool allows us to configure various modules like the airbag and abs to the new cluster

with the cluster in and programmed the car started and ran fine, saving the customer alot of money and time on new parts.

Citroën DS3 airbag light

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.

Insignia non runner

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.

C4 Cactus battery going flat

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.

A battery support unit is essential for programming to maintain battery voltage during the procedure.

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.

Starter Motors Widnes

Starter Motors Widnes

Here at Widnes Auto Electrical, we can either repair or replace Starter Motors . We will diagnose the problem and then find a suitable result to fix it, or if the Starer Motors cannot be fixed, we will replace it. Below is a short summary on how we test Starter Motors :

First of all the starter motor would be tested to see if it functions properly; there are a number of common symptoms of a bad starter…

  1. When you turn the key to crank the engine, nothing happens. The engine will not turn over.
  2. When you turn the key to crank the engine and all you hear is one loud click. The engine will not turn over.
  3. Or you turn the key to crank the engine and the engine turns over but very slowly and then stops.
  4. The battery might be good and you will know this if; you bought a new one thinking that was the solution to the problem, or you got someone to help you jump start the vehicle to no avail.

Summary of the On Car Starting Test:

This is a brief summary of the tests that we’ll be carrying out to get to the bottom of what’s causing a no crank condition on your vehicle. With the tests that we’ll be carrying out you’ll be able to say with absolute certainty it is a bad Starter Motors or completely eliminate it as the cause of your vehicles problem. Although the tests are fairly simple, if you do them on your own and you find the root of the problem, then all we need to do is fix your problem and everything will be solved much, much quicker.

When you bring the car or vehicle to Widnes Auto electrical, these are some of the checks we run:

  1. Firstly we test the battery before anything else. As this is a simple multi-meter test.
  2. Our trained mechanics will test that the Starter Motors is receiving 12 volts on the battery circuit.
  3. We will test that the Starter Motors is receiving the start signal from the ignition switch.
  4. A voltage drop test for the starter battery and the ground circuits.
  5. We will use a jumper-wire or an appropriate tool, apply 12 volts to the start signal wire.
  6. Checks will be done to eliminate a locked-up engine or a locked-up A/C compressor.

If you think you’re having problems with your Starter Motors, or you feel that you need it replacing then please contact us, also if you want to know more about the other electrical services we provide with vehicle electronics then again please don’t hesitate to contact us and a member of our friendly team will be in contact with you shortly.

2016 Peugeot 2008

This fairly new Peugeot 2008 came in to our workshop with a charging problem.

Voltage across the battery was measured at 12.3volts when it should be more like 14.5volts. The wiring was checked, the positive lead was load tested and found to be ok, as was the earth. This is a smart Alternator and is controlled via a Lin signal from the engine ecu, this was tested and found to be good.

At this point most garages would have fitted a new Alternator, not cheap on theses cars, only to find the problem persists. We go further to prove a fault.

We have equipment that we can plug into the Alternator to simulate the control signals from engine ecu to the Alternator.

When we did this, the Alternator worked perfectly.

So, if the wiring is good and the Alternator is good what could the fault be?

Through experience we knew that some cars especially Peugeot can need a update on the software in the engine ecu.

Using the official dealer tool we can safely update control units without doing costly damage.

With the update completed the car was checked again. The charging checked and showed 14.4volts, perfect!

The customer was happy to avoid unwanted expense in the fitment of unneeded parts and went away happy!

BMW 3series Alarm fault

This 3 series came to us after the dealer said there was nothing wrong with it.

The alarm was going off intermittantly.

A quick code read showed several faults

Testing the car seemed to show no faults .

But looking at the BMW site it showed a TSB (technical service bulletin) for this fault. The switches in the door become worn with age and set the alarm off.

The solution is to reprogram the frm module and this gives the switches larger tolerances so alarm doesn’t go off.

Depending on size of file this can take minutes or hours to download.
A stable battery voltage is essential during this process. If battery goes flat during programming it would damage the module.
