Thank you for your replies, this is very much appreciated 😊

Hi Cliff thank you for your message I appreciate you taking your time to read. The battery was replaced a couple of years back I believe, it was done at a Halfords auto centre and since they fitted it the start stop function never worked after that and they said they don’t do that there, I was annoyed at the time as wish they had mentioned this before we went ahead with it there and after that I just got used to it and didn’t bother getting it sorted, in hindsight should have done so. This problem with the engine cutting off has only been a recent problem so I’m not sure it could be to do with that could it?

Good evening. I would really appreciate some help, I’m new here so sorry to bore you but here goes…my Audi a3 2010 diesel started playing up the other day struggling when going around a round about and when going up hill (jerking and juddering), the next day the same but started to cut out when idle waiting at lights etc, took to a garage to see if possibly fuel filter, they looked at the fuel filter and said looks clean (not sure why they didn’t just change it) plugged it in but no codes except ECU code fault but I’ve had this for ages as it seemed to have thrown this up when we had the battery changed before and then couldn’t map it to work with start stop function, they said it could be an issue with the ECU. Spoke to an ECU remapping guy and he said we could order one and he would remap but just doesn’t think it is this. Called the AA out as stalled again but managed to get home and he plugged it in to check performance and he said it could be fuel filter but worth changing the housing too, so we changed the fuel filter but not the housing as need to buy aftermarket one and will take a while but still doing it and getting worse. Is it worth changing the fuel filter housing has anyone had a similar problem? I just don’t know when to begin with it as if we take to another garage they will charge loads just to look trying to identify the problem before we can even fix it. Could it be the ECU or fuel filter housing, it could be so many things. thank you for reading and sorry if I’ve gone on!!
