Hello everyone, I’m hoping I can get some advice on this issue, been happening for a while now. A4 65 2.0 TDI quattro S tronic, currently at 71,000. when accelerating usually between 3rd and 5th gear there is a knocking/fluttering noise coming from the engine. Tends to be worse going up hill. I initially thought it was the octane rating, switched to v-power, did not solve, I use arch oil in every tank which helps but not solved. cam belt is due a change, could this be the issue? I’m hoping it’s not an issue with injectors? a strange thing I have noticed is the car is brilliant to drive when it is doing a regen, no noise when accelerating, car is smooth to drive feels like new. I assume this from the extra diesel being used which is making me think there is an issue with the fuel injection or ratio which could cause the knocking on acceleration. any help would be appreciated!

Had a 2014 tdi in last week going into limp mode under load, glow light flashes on dash. Fault resets every time ignition is cycled. p2279 intake air leak stored in ECU. carried out air leak test with smoker, no leaks present . Fault turned out to be faulty MAP sensor giving incorrect readings, only available from the dealer at present time .. retails at £52.28 + vat Nice little DIY fix that will hopefully help some of you 🙂 https://youtu.be/kqIB83gMszk
