Hi its probably because their code reader is generic and has to deal with most types of vehicle, although Snap on etc are expensive they are not manufacturer specific and will not give an interpretation of the code, it then gets more difficult as the manufacturers are now making codes generic which basically means it could be one of a few different sensors, but my best guess is the oxygen sensor as the symptoms you describe are virtually the same as mine were at around 80,000 miles and if your sensor has never been changed the likelihood of it being that is very high.

Steve.

Thank you very much mate I will try that tomorrow and see what happens

Hi I don't know what you used to get the code but VCDS tells you the generic coding but also tells you the sensor thats playing up but its my guess thats the culprit as the symptoms are too close to mine.

Steve.

I took it to a local garage and that's the code and explanation I was given nothing specific to where the problem actually is it's the fact I don't know where the problem is specifically so no idea what or where to look

Hi it could well be the oxygen sensor my one was on its way out this is hanging in the exhaust just after the cat and has a horrible life, constant heated gas, and it gave the same generic code and did the exact same thing as yours its where the heater element in the unit begins to fail.

Steve.

Thanks mate I will check that first thing tomorrow any ideas right now are good ideas as I am at a loss

I wonder if a previous owner fitted after market speakers on the rear shelf at one point, which he then removed before selling the car, leaving the original speakers without any wiring.

That's sounds right to me so guess I got to re wire them 

Just now, Steve Q said:

It's definitely off that someone would go to the trouble to fit speakers but wouldn't wire them in. 

The speakers are exactly the same as in the front it's had myself and my friends baffled they are there but no wiring to them what so ever in the door very strange

Should be able to find a wiring kit on eBay. 

Thank you I will look into it 

I have an audi a3 2010 model does anyone know why I have rear speakers in the door panels but they are not wired up took both back door panels of and I can not find any wires to power them so do I need to wire them up from my head unit.Has this happened to anyone else does anyone have any ideas please

Hi that probably means the drive for the EGR pintle is going down hill, the other causes can be module related or a sensor that sits in the high pressure fuel pump, I would try a new EGR valve first its the cheaper option and sounds the most likely cause.

Steve.

Thank you am at a loss really had enough of it all  now to be honest really am what ever I try or do never works

Hi do you mean P4077 as this has nothing to do with the EGR or Throttle its a valve that controls exhaust back pressure.

Steve.

The code I am getting is p0407-07E8 pd generic but after running for a while it goes off and no problems only happens after the car has not been used for an hour or so I am at a total loss 

Today I cleaned my egr valve and throttle body last week I replaced the egr selanoide yet am still getting code p407 and even though I have more acceleration than before I am still In limp mode please can anyone help please
