Mercedes A-class Airbag trouble

2013 Mercedes came in with airbag light illuminated,  a quick code read showed a fault with passenger side occupancy sensor. This sensor detects when someone is sat in the passenger seat and also their weight. This sensor is very important because if the weight of the occupant is small it will not activate airbag in a crash situation as it could kill the child.

Many owners with this fault may decide to fit an emulator to kid the car because it’s a cheaper alternative to a correct fix. This is dangerous because it tells the car that someone is sat in the seat and the weight of that person is an adult so the airbag will go off whoever is sat there.

This customer decided to fix correctly which requires the seat to be removed and the upholstery to be stripped.

With the new part fitted and coded in, the fault light extinguished. Job done!

Peugeot new key

A Peugeot into our workshop with faulty remote, which  is all part of the key.

With the correct tools we can extract the pin code from the vehicle that then allows us to program in new key.

A quick efficient job and back to the customer.

2009 Transit Connect non runner

Into our workshop came this connect that after being left for a couple of weeks wouldn’t start. A new battery had already been tried but problem remained. A code read revealed ecu processor internal faults so the ecu was accessed and removed

The ecu was opened to check the pcb

Once apart the fault was obvious

This is unrepairable and a new one expensive. So a 2nd hand unit was sourced and fitted. With the correct equipment this was done quickly.

The Ford immobliser system known as PATS has to be matched in the ecu and instrument cluster. To do this you need to access security in the cluster for which you need a code.

The vehicle gives you an outcode and this equipment gives you the incode response. When entered diagnostic equipment then matches ecu to cluster and vehicle started straight away.

We suspected damage was done due to jump starting and putting the leads on the wrong way. Luckily for the customer no other damage was done.

Volvo V60

Volvo came in for the tow electrics to be wired up. We may not be the cheapest but our work is 2nd to none. Not a butt connector in sight all connections soldered and water proofed. Do it right do it once

BMW 7Series non runner

This vehicle came to us as a non runner, 3 other technicians had already been out to the vehicle to try and fix the trouble without success.

Reading the vehicle with a diagnostic device showed various communication errors between modules. Knowing BMW cars we knew voltage could be the reason so many modules were having issues. The battery was tested and replaced .

Then with the correct tools we are able to repair the coding errors

With the coding complete the vehicle started and ran perfectly.

Corsa Airbag fault

In for airbag faults

Wiring for the system was checked and found to be OK upto the seat. So the seat was removed and stripped to gain access to wiring inside

On examining the loom you can see where the loom has been trapped and cut through

A simple repair was made and the seat refitted, codes cleared and tested.

Ford Transit Connect

This vehicle came to us with a problem with the gauges. With accurate wiring diagrams we confirmed the wiring was good.

A second hand set of gauges were sourced, fitted and with the correct tools the keys, milage and immobiliser were coded in

Ford Transit locking fault

This vehicle came to us with locking issues. It had previously had a new interior fitted due to fire. A quick look at fault codes revealed antenna fault. On stripping interior to examine wiring it was found to have been repaired to a very low standard,

It was also found that the antenna was missing. A new antenna and loom was sourced and the wiring repaired to a safe standard. The locking worked without any programming necessary.

Ford Fiesta

Ford Fiesta in for the radio not powering up. It had been to a ‘specialist’ that had tested radio and said it was a wiring fault.

These radios come in 3 separate pieces, the display, the audio unit and the keypad. With accurate wiring diagrams we were able to test feeds and grounds to the audio unit and also the communication lines know as Canbus, all proved good. So even though a radio expert had said it was wiring we have proved the wiring is OK.

We didn’t suspect the display as it would still have sound. The audio unit was checked for current draw and a thermal camera used to see if it was getting warm. This isn’t 100% test but an indication it’s working. There is no way of testing keypad, only substitute for another which we had available.

This proved to be the problem as it came on and worked perfectly.

Another job successfully completed without any guess work or unnecessary parts fitted.

2007 Focus ST gauges

Ford Focus with cutting out and losing power issues, diagnosed by us using reliable and presise test plans. Enable us to diagnose problems quickly and accurately. In this case the gauges were the problem and we are able to repair these saving the customer hundreds against new.
