Investigating the issue at our Volkswagen Van service centre
We recently had a phone call from a regular customer to say he had an intermittent engine management light on his VW T6. We tend to know all the little niggles with these vans and had already ruled out a few possibilities before the van arrived. When quizzed about his issue he explained the van still had power and felt to be driving as normal.
Once on site at our Volkswagen van service centre we retrieved the fault codes and set about carrying out tests using our trusted diagnostic methods, the fault code we retrieved was one we have seen many times before P040100 Exhaust Gas Recirculation Valve low flow. As per most intermittent faults in the van, they can be harder to find than what is known as a static fault, i.e the fault is permanent.
We already knew from the vehicle’s history that the EGR valve had been replaced in the past with a genuine unit from VW, we, therefore, set about our diagnosis using the VW dealer tool ODIS to help facilitate the Volkswagen van repair. Within ODIS you have access to technical bulletins or TPI’S that help with known concerns, one particular bulletin caught our attention in regards to certain driving styles causing issues in the emissions system. At our VW Van service centre we were armed with a test plan. We carried out a flow test on the EGR cooler which confirmed poor flow. The vehicle had only covered 10,000 miles since its last replacement so we determined that cleaning the cooler was the best option. A phone call to our friends at Tunap confirmed they had the correct chemicals to help with our cooler clean up, and we were able to facilitate the VW van repair.

Once complete another flow test confirmed the cooler was back to full flow, a bit of advice about drive cycles was passed onto the owner who immediately set off down the M62 with no further reported concerns.
