Brought to our workshops today was this water cooled Mercedes alternator which had stopped charging altogether. We were able to strip this down and effect a repair for a fraction of the price of a new unit. We load tested all the working components and found the regulator to be faulty, replacing this single item worked out at cheaper than half the price of a complete unit. 1 very happy customer picked up the Alternator 2hrs after dropping it off and fitted it back on and was on his way.

Audi A4 2008

Today we were presented with audi with radio interference trouble that had been to various other garages for repair that had failed. The first thing we had to do is to repair the previous garages work, which entailed repairing the aerial lead that went into the rear of the head unit. Then we could investigate the original fault. The cabriolet A4 has 2 amplifiers in the boot lid and the cables running to them often break or corrode. So we traced the leads of which there are 3 and found the broken lead which is difficult to do as the break is usually internal and cannot be seen externally. We would then usually replace this lead but as time was a constraint we affected a repair on the lead which also saved the customer money. The customer went away happy with the radio interference rectified.



Brought to our workshop today from another garage was this very nice 58 plate Alfa Spider with a host of electrical faults. What we have found with this car aswell as most modern cars is water ingress into the wiring harnesses which then tracks along the loom until it reaches a plug or component. In this particular case the drivers door had water ingress which had got into the door module sending sporadic signals to the main BCM(controls most electrical systems on vehicle) which had affected its operation causing other systems to throw up faults. So you can see how hard a fault like this is to diagnose, one system completely separate from another still effecting its operation. But here at Widnes Auto Electrical our experience in these kind of faults enables us to diagnose and repair this fault. We removed the door module and wiring loom from the door and repaired both without the expense of replacement parts. A very happy and relieved customer picked up his car the same day fixed at a very reasonably price.
