AdBlue problem that kept running down despite being full... Tuning company fixed it but looks like they removed the AdBlue by disabling exhaust temperature sensors in the ECU and did a remap as well. 30 miles later DPF warning came on and now in limp mode. I went to Audi and they have come back and said they cannot put any software on the ECU as it's been tuned and are saying I should get a replacement ECU before they look at the initial AdBlue issue. Can I ask what you think about that please? They're quoting ~£1950 for a new ECU. I have a 2016 A5 quattro 2.0 TDI. Any advice would be massively appreciated.
