I paid ClickMechanic £329 for an oil and filter change and a DPF clean and regeneration. SAS Steering Alignment was assigned the job. After the mechanic did the job, he made a point of telling me the clean and regeneration of the DPF would probably not work and if the warning light came back on, I would need a new DPF at a cost of over a thousand pounds. Guess what within 5 days the warning light came back on. The mechanic (SAS Steering Alignment) that did the job was not interested in helping in any way and pointed to what I was told after the job was done, that I needed a new DPF. Raised a complaint with ClickMechanic, who echoed what the mechanic said and pointed out it was my fault and I should have paid for a diagnostic check from ClickMechanic as it would have shown I needed a new DPF. As Clickmechanic and SAS Steering Alignment were not interested in fixing the problem unless I spent over a thousand pounds, I took the car to a local garage who put the car under their diagnostics and said the regeneration had not been completed correctly. They completed the second part of the regeneration on my car and the DPF light went out. No need for a new DPF. Raised a second complaint with ClickMechanic, the complaint got shut down and nothing was resolved. This cost me another £48 to fix Clickmechanic and SAS Steering Alignment mistakes. By this point I had suspicions that Clickmechanic and SAS Steering Alignment were trying to get me to pay for something that was not needed. When a friend told me he now worked for a company that only cleans DPFs and offered to put it through his diagnostic tool, I accepted. As it turned out the DPF cleaner had not been put in my car or if it had been it was not put in correctly. He gave me a report to back this up. If the DPF had been cleaned the ‘DPF Difference Pressure Sensor’ would be below 10 hPa, mine was 35 hPa. To date neither Clickmechanic or SAS Steering Alignment are interested in giving me my money back even though the DPF Regeneration was not done correctly and there was no sign of a cleaner being put into my car. They just want me to give them another thousand pounds for a new DPF, even though this is not needed.
