Apologies for another DPF/EGR thread. I have had my A4 '06 2.0tdi 170bhp for about 6 months now and have got to the point of EGR and DPF problems. I knew what I was letting myself in for as I did research before buying the car but I am having trouble to find a solution for my new problems.
Firstly my engine warning light came on and was diagnosed as an EGR fault. After a google search I came to the conclusion I was going to have a bash at cleaning the EGR valve and replacing the 2 gaskets and seal. Before I got a chance to do this my DPF warning light came on. I do a regular amount of motorway driving and thought this would be cleaned regularly, only to recently read that you should be sitting at 60mph in 4th gear for 15-20 minutes for this regeneration process to come into effect??? Anyway I went to try this that evening and kept on getting diverted off the motorway due to raod works so only had a 10 minute max run at it. The next thing the glow plug warning light starts flashing and the car is running in limp mode...
I am just an average Joe and not a mechanic and am looking for some much appreciated advice. When doing research I was under the impression the DPF and EGR could be removed/bypassed via a software update but when getting quotes I am told the DPF needs to be emptied out or physically cut out. And the EGR has to have blanking plates fitted.
All and any feedback and advice would be much appreciated. I am working away just now so the car has not been getting used since it went in to limp mode and I want to avoid using it until these problems are resolved.
Thanks in advance,
