Good afternoon everyone. My son has been enjoying his 2018 Audi A3 and has had no issues at all apart from his scrape down the side a few months ago. He went to Alton Towers on Thursday and had an enjoyable journey back despite the usual M6 traffic. However he started his car to go to work on Friday and immediately got an engine management light on (no limp mode). Also his reversing sensors have stopped working , his eco has stopped working and has always worked since he bought the car and finally he is getting tyre pressure warnings despite his tyres being all the correct psi. I have not been able to check the for any codes as we have been on opposite shifts but should get a chance later on to check the codes and will also check the battery voltage. I am no expert but it is showing signs of maybe a failing battery as my old 2004 Jaguar S-type threw up all sorts of codes when its battery failed. Any more ideas or suggestions would be greatly appreciated. Cheers Colin

Colin.

Those are classic signs of a defective battery. When you buy a new one ensure you get it coded to the car else you will get even more problems.

Thanks Cliff much appreciated.

Ok I have tested the battery using my Launch CRP123E code reader. The battery resting voltage was 11.8v so that confirms it needs replacing. I have cleared all the codes for now but they will come back and I have ordered an Exide 096 EFB battery which is the direct replacement for the EFB battery which is fitted but I do have Battery reset on my code reader so I can code it to the A3 if need be. Thanks Cliff for your help. Regards Colin 

Watching with interest. 
how do you find the launch CRP123E code reader  ?

Hi Ian, So far so good with it, cleared a couple of codes on my sons Peugeot 108 and most importantly coded a new Exide EFB battery to my sons A3. Just to add before I coded it there were numerous faults showing with the new battery fitted so it certainly did the trick. Good piece of kit and I also got £20 off as some sellers are doing £20 off vouchers on Amazon. Regards Colin   

Thanks Colin,

Good to hear.

Maybe of help to others:- 

I now also favour Exide batteries, and have bought a couple from Tayna Batteries ( no connection with the company) at competitive prices via. their EBay listings.

That’s good! Does it support activation of features … alarm bleep on off etc?

Not sure Ian, Here is a write up on it and they have dropped the price lower than on Amazon. Regard's Colin
