Hi, I've just joined up for two reasons..... 1, to make contact with the Audi scene generally, and 2, I run an elderly A6 which it's a bit hard to get tech advice and parts for, so hoping to extend contacts there. I did run an S6 a few years back so I've got 'previous', but I'm now down the other end of the MPG and performance figures with a 1.9tdi! All good fun though, generally a pretty good workhorse so very happy with it. I hope to meet up with some of you when these things are possible again 🙂 Cheers, Adam

Hi all, Just a quick post to say hello and thank you for allowing me to join your group. As the title says im a little embarrassed as 1. I didn't know this group existed, and 2. I only joined as I have an issue. Anyway, now I do know this exists, im happy to say I hope to be here for the foreseeable future 🙂

Thanks for the warm welcome :-)

Hi Ryan.....welcome to the Forum Good to have you onboard

Hi Ryan, Boredom is a terrible thing, I have been sitting in the car playing with the laptop whilst waiting, right there appears to be two choices depending on which engine you have [usual bullocks] but the good news is they are not big bucks to buy, the downside is the diagram showing the sensors is showing them in a large white area with no indication of where they go, very frustrating, but I was talking to my mate who installed my VCDS and driver and he pointed out that the part no you want for the sensor will be in the description of the fault, that narrows it down and why did I not remember that, must be going senile, if you can throw in an engine code I can go down to one of my customers garage tomorrow and hijack his Autodata repair programme and find out where its located. Have a look at the fault code again and see if either of these part numbers throw up a flag, 03L 957 147A.or 04L 907 601. With regard to the sensor causing the loss of power and it cutting out, most definitely that is the cause as the ECU cant get its head round mixed signals so if the fault gets that bad it simply shuts the whole thing down or goes into limp mode, I had it with a Ford cab I had coming home from stansted one night, going through the lanes the !Removed! thing kept cutting out not good at half past stupid in the morning, so I nursed it down to the only garage for miles got the reader out and scanned it, it showed crank position sensor intermittent fault so after a bit of head scratching a bored AA man that patrols that area walked over and asked whats the matter when I showed him the scanner he went and got his big search light torch and we had a look. the fault soon became apparent as when idling there was a steady drip of coolant coming from the water pump and down on to the crank sensor so I bought an overpriced Bars Leak from the garage put that in the coolant tank, WD40d the sensor to death and made a run for home, if any sensor starts to break down internally the only answer is replacement. Regards Steve.

Hi Ryan I have an airport take out and pick up to do but I will get to it as soon as I get back and should have your answers for you late afternoon if thats O.K. in my line of work you have to grab what you can when you can, BTW the sensor we are looking for cannot block up as its a Hall sensor, [solid state] so like an ABS sensor it relies on a circular metal ring with teeth or a magnetic ring to function. Cheers mate.

Hi I think the G40 or crankshaft position sensor is probably located behind the cam belt housing but if you can send me your VIN NO I can check it on my ETKA system which will with a bit of luck throw up A. the exact location, B a part number, the reason the DPF is blocking is because this sensor is malfunctioning and the ECU won't sanction any regeneration because it thinks doing that may damage the engine, furthermore I would not recommend a DPF delete especially if the car runs adblue as your likely to need VCDS to keep putting out the Christmas tree lights on the dash, then there is always the issue of increased emissions. the DPF is under the cat on the left hand side of the engine and from what I have seen you have to remove most of the front of the car, you might be better served sorting the sensor do a regeneration and see how you go, other than that if you are still not happy try Terraclean. A man with information and codes, priceless...... Regards Steve.
