I need some help as I feel like committing suicide .....
My '99 A3 1.9 Tdi Sport, with 183k is doing my head in ! Whilst merrily driving along the dual carriageway then going to accelarate under load (like uphill) the limp mode kicks in and lost of power .. so no overtaking ! This happens everyday on the way and return to work. In less than 5 miles from departure point. However, if I stop at traffic lights and turn the ignition off momentarily the ability to overtake returns for a brief period. The Audi dealership said turbo is losing gas and needs a new turbo, but I am not yet convinced because it works ok until the limp mode kicks in and also after I turn it off and restart it is fine. There is no smoke or noise coming from the turbo. This started as a intermittent thing, which is now regular as clockwork. However, I visited a friend who had a look at a couple of things under the bonnet, intake hose and a value behind it, also looked at the air filter, took it out gave it a tap (it is in pretty good condition) and put it back. He suggested I looked at the inlet hose when it happened with the engine still running to see if the hose collapsed. I went on my way put some diesel in and put my foot down waiting for the inevitable .. no limp mode ! I had a good drive round about 15 miles still no limp mode ! Unfortunately my joy did not last and the next day going to work the same thing happened but I remembered to look at the hose before turning off, and to my disappointment it was ok. My next course of action was a diesel place. Here they did a diagnostic and told me it was the wastegate had stuck so they did an adjustment, but unfortunately that did not work either. I have since changed the fuel filter too, and no difference there either. A friend with one of those electrical meters had a look at the Air Mass Sensor, the connectors were clean and the his tests showed the right currents or whatever were good. When it happens I can rev it and the revs will go up with no problem, it just happens under load ... it is also pretty embarrassing too !!!! So can anyone help or recommend somewhere in Sussex I can go to ???
Bytheway I get no codes or lights appear on my dash either !
