Hi,
I wonder if anyone might be able to help with a diesel particulate filter problem on my Audi A3 2.0 Tdi Black edition, 11 plate. It has done 117,000 miles and I got it in October last year. Since then, the dpf light has been coming on every 2 weeks. Each time the light illuminates I take it on the motorway in 4th or 5th gear and the car regenerates and the light goes off within about 15 minutes. However, around 2 weeks later it comes back on and I need to get back on the motorway.
To be fair I mostly do town driving, short journeys and maybe a bit further at weekends when I take the family out but still generally less than 10 miles. I realise this type of driving better suits a petrol but my last car was a diesel and I never had any DPF issues (perhaps it didn't have one) and I wasn't aware of potential DPF issues before I bought the A3.
The car was last serviced in July 19. Just Oil and filter change. I've had the fault codes read and only one fault was returned and that was with the Gearbox Neutral Position Sensor (which is probably why my start/stop isn't working, but anyway that's a separate issue and one i'm not too bothered about!).
I guess the car isn't getting a chance to regenerate with the start stop short journeys that I do but when the light does illuminate I can force the regeneration by driving at 3000rpm for 10-20 mins so the car is able to regenerate.
Is this normal behaviour or is there something going on here?
What are the next steps in diagnosing any issue? A garage I went to recommended a Force Regen and then a Full service at a cost of £350 but there's no guarantee that would solve the problem. If it didn't, they recommended a DPF clean with fluids injected at a cost of £300.
I've been using Shell V Power diesel for the last full tank and a half.
Any advice would be great! Thanks,
Nathan
