Father in law has a TDI Tiguan, and has had a shit of a time keeping the Diesel Particulate Filter clean. He has taken it on long highway runs, hard runs up the hills, everything the VW stealership has suggested and it hasn't cleared up. Yesterday it has finally cracked the shits and gone into limp mode and takes minutes to reach 100km/h (no joke).
VW wants $4000 odd for a new filter and he will be back at square one. Even though the thing has only done about 20k, he has said they told him its not a warranty thing because the book says how to drive it right.
I have done a bit of research myself and found cunts in the UK with the same dramas who end up getting a DFP Delete pipe and a retune for half the cost of the VW option and ending up with more power.
Finding this shit in Australia has been a bit harder. Does anyone know someone/somewhere who can do this and whats actually involved? I'm thinking the pressure sensor will need to be tricked into thinking there is a functioning filter in place for everything to run smoothly.
Also, if it helps, I'm fairly certain the thing is identical to the TDI Golf, so that stuff should fit up properly.
