Hi, yes I have resolved this now, one of the drive shaft fitted at first was the wrong one, i changed it and car stopped vibrating now, also check to make sure exhaust is not touching body where it goes up to engine from gearbox

It’s not coding, it’s a basic battery,, it supply’s no information to the car just a live and neutral. your changing the parameters in the cars computer to let it know you went from EFB to AGM, would have also had amperage information needed, nothing to do with overcharging the new battery as alternator max output can be absorbed by the battery all Day, just like they have for years and years. The battery information is so the start start system has more information then just what voltage it detects. If you don’t supply the new information the car just doesn’t work at it’s maximum potential, it still works thou

Happy Christmas, if the worst problem you get this new year is choosing which polish to use you will have had a real result, be lucky my friend. Steve.

Evening all and Merry Christmas. Not my first Audi (TT Roadster) but just returned to the brand with an A5 35 TDI S-Line. My Passat CC did 196k miles so we will see how this one gets on. This is also my first switch to an automatic - feel like I'm getting old! 🙂 Cheers, Alan

David. This topic is a duplicate so I am locking this one. Posing the same question several times will not gain you any advantage.

Regarding new battery programming, a battery can not be coded to a car, it’s just a battery with 2 terminals, the process involves editing the cars software to inform the car what type of battery cell technology you have fitted and what amperage the battery is, when this is done the battery must be at almost full charge as this is what the software is expecting, this then allows the alternator and start stop systems to work at there optimum efficiency and measure the battery’s health

Hi Mark, on a lot of the diesels the aftermarket induction kits don't offer any benefit other than increased heat soak. Just got an upgraded panel filter from k&n or pipercross etc
