Dale 01 Posted February 24 Share Posted February 24 Hi I'm changing my throttle body for a new one, what I want to know is, are they plug and play ie already set up or do you have to "tune" them in. I read that you can do this by turning the ignition on, not starting the engine, and hold down the throttle pedal for 15 seconds then turn the ignition off and then start the car and it should be done. The reason im changing it is because sometimes it doesn't idle properly and other times it goes into limp mode with the ESP warning light coming on, I have to turn it off then turn it back on to clear it. I've had it on a machine and it threw up some codes, pic included. It has a factory recall on it but Audi's wont touch it until all problems are fixed and to be honest i cannot afford their prices.

Dale 01 Posted March 18 Author Share Posted March 18 Hi Jason Haven't got back on here as im still waiting to send the throttle body back to Autodoc. They have to be the worst company to deal with. Whilst im on this subject, do you know where or if I have a MAF sensor. Thanks Dale Quote Link to comment Share on other sites More sharing options...

Thanks Dale Hi all vehicles are fitted with a MAF sensor its on the induction side between the air box and before the turbo normally a cylinder with a plug attracted to it, inside is a coated diode which is heated up and then allowed to be cooled by the incoming air this tells the ECU the temperature of the air as well as humidity, the ECU adjusts the injection accordingly based on the correlation of information from the MAP,MAF, and throttle position sensor on the peddle, all of these items need to be adapted when replaced to maintain synchronicity within the system.

Dale 01 Posted March 18 Author Share Posted March 18 Hi Steve I believe this to be the case. I have a 2008 1.6 8v a3 sline and have looked for it countless times ive had the pipe off between the filter and the throttle body and there's nothing there, my car is idling badly and i want to change the throttle body but Autodoc Sent the wrong one and also change the MAF if I can find it.

Thanks Steve Dale Hi from all the parts diagrams I have looked at its right next to the airbox can you post a picture of your airbox and induction pipe its definitely there, the airbox pipework runs to the turbo not the throttle body.

Dale 01 Posted March 19 Author Share Posted March 19 Hi Steve My car is petrol and does not have a turbo. I've been reading other posts similar to mine on here and it seems that my car does not have a MAF, which i find hard to believe,. Im going to renew the spark plugs and leads at the weekend. I took the throttle body off and cleaned it but to no affect. Baffled, I am. I will post pictures of my engine very soon. Dale Quote Link to comment Share on other sites More sharing options...

Dale Hi thank you for the pictures, I honestly think that the throttle body has the MAF in it but I am also concerned that the throttle position sensor on the peddle may also be at fault, its only a unit thats like old fashioned hand scales whereby the peddle pulls a spring arrangement within a sealed unit which pulls an internal resistor past a series of contacts which register the required position of the throttle butterfly to the throttle housing.

Dale 01 Posted March 20 Author Share Posted March 20 Hi steve I have a friend who says he's going to reset the throttle body on sat afternoon. I had the EPC ( Electronic Power Control ) light come up on the dashboard snd when I looked it up it said that it indicates a problem with the vehicles throttle system which could include the accelerator pedal, fuel injection throttle body. I'll keep you informed Thanks Dale Quote Link to comment Share on other sites More sharing options...
Dale 01 Posted March 20 Author Share Posted March 20 Hi Steve Sorry to bother you again but do you know what this is on the engine that i have circled in blue, it has a pipe from the air filter box and electrical wires coming out the back.

Thanks Dale Hi Dale, from memory I think its part of the fuel vapour purge system this collects vapour from the system filters out any bits and re burns the vapour, all part of the wonderful emissions control. I think the reset will prove useful as my neighbour had similar symptoms on his old Polo after he had fitted a new throttle body it ran like a bag of nails until we readapted the new body, in saying that if it still wont run properly it probably is either the body or the position sensor, not much help but at least it will narrow it down, again from memory the position sensor on the peddle is plug in and play as its only a slave unit for the throttle body.

Dale 01 Posted April 18 Author Share Posted April 18 Hi Steve Still haven't forgotten about keeping you informed but my friend still hasn't gotten back to me yet but we have both decided that a new throttle body is the step forward As before i will keep you informed Dale Quote Link to comment Share on other sites More sharing options...
