The owner of this vehicle was referred to us by a local Seat specialist. The vehicle had developed a fault causing the engine management, glow plug and DPF lights to illuminate on the dash.
We carried out a full diagnostic session which revealed a fault code for the intake throttle control valve. On initial inspection we could see the part had already been replaced.
After carrying out some further testing using a combination of specialist tools including our VAG OEM diagnostic software and an oscilloscope we were able to determine that there was an open circuit in the wiring harness between the engine computer and the valve itself.
A new wiring harness is expensive and is very labour intensive to fit.
The vehicle was a driving instructor’s car so minimal downtime vital.
We narrowed down the section of wiring where we believed the fault to be then opened it up which revealed the broken wire we suspected.
After soldering in a 2 new wires and resealing the harness we carried out a an extended drive cycle so that we could observe DPF regeneration taking place and verify the repair.
Another satisfied customer!
