Just sent to Skoda UK - Awaiting response...…. Anyone else had similar issues & were they resolved by Skoda? Skoda Superb 190 TD Sportline (25,753miles) My vehicle emission control light came on last week & I immediately booked it in to Hayselden Skoda Doncaster for a service & assessment of the fault. The car was serviced & the fault cleared. However I notice no record of the fault has been logged in the Vehicle Health Check or Maintenance List. I raised this with the service manager & had a chat with the Technician. I was informed that the fault had been cleared & there was nothing to worry about as it requires a software update that is not yet available. No timescale was given for the software release. I am aware that the fault is with the Bank-1 NOx Sensor (Fault Code P20EE00) & that this is a longstanding issue with this emissions system – I am not convinced that it is software related, or if it is why has it not been addressed sooner as a recall – I can find several references to this on the internet, none have a resolution. As an Emissions control Engineer with over 20 years’ experience in DOC / DPF / SCR / SCRoF technology, I am aware how delicate the balance of Urea injection & NOx conversion is. Therefore, I have to raise this issue of incorrect NOx readings & the detrimental effect this can have on both Emissions & other parts of the Emissions system, most notably either Ammonia-Slip or formation of Urea Crystals in the mixing chamber prior to the SCR. Both scenarios will, in time, result in irrecoverable failure of the emissions system and require replacement. This concerns me greatly & with around 12m left on my vehicle warranty, I need to raise this as I cannot help but feel that Skoda are letting the problem develop knowing that it is most likely that the failure manifesting now will not become a serious issue until out of the warranty period – To be absolutely clear, the NOx issue my vehicle is experiencing at present is a Skoda fault that has started within the warranty period & I fully expect Skoda to take responsibility for this. I look forward to your response Martin Wilson Former Programme Manager – Eminox Emission Control Systems SCR System NOX Conversion.pptx
