Why is my Volkswagen Touran using so much oil?
I have a 2013 Volkswagen Touran 1.6 diesel with 13,000 miles on the clock. Recently the car has been giving me some problems. A while ago it was emitting a strong oil smell, which turned out to be a split breather pipe. However, since then, the car has been emitting strong burning smells. I've also noticed the oil level rising. I use the car as a taxi, could the DPF need a remap?
I would guess bad oil smell due to EGR failure that is extremely common and extremely expensive on the 1.6TDI in a Touran. The burning smell is the DPF trying to actively regenerate, but if the engine oil level is rising then the ECU is trying to inject more fuel into the engine than can be burned in the DPF and the rise is fuel contamination of the lube oil. The car is anyway due for the NOx emissions defeat software remap and hardware modifications, but these have not come on stream yet due to the immense difficulties VAG is having with less complex emission defeat remaps.
