Hello all,
My TDi90 Sport normally returns around 50-54mpg in daily use (commute is a mix of motorway and stop-start heavy congestion). On the last tankful, this dropped to around 45mpg, which I put down to a load of really, really bad congestion (average speed for the tankful was down 10mph too) due to some major roadworks near where I work.
But the current tankful is showing around 44mpg, and if anything, traffic has been better than average lately. I do notice that in very cold weather (cold for Manchester, anyway) the average often drops to around 48-49 anyway, so the current figures are unusual. It may be just a blip and a combination of unusual traffic, but I'm loathe to just ignore this sort of anomaly.
I do recall something similar happening one winter about 8 years ago. No fault found by Audi, then about a month later, the turbo blew. May be just a coincidence, obviously, but when Awesome replaced the turbo, it transpired that the hose from the intercooler was leaking and I suspect this had caused an overspeed. I don't hear any obvious extraneous noises this time, and am alert to the possibility this time around. I'll monitor things for another tankful over the holidays, and see where we end up, but some thoughts from the assembled luminaries wouldn't go amiss.
Thanks.
Steve
