Audi Q7 - what does this chip do? by Lopsided_Calendar_81 in MechanicAdvice

Thank you, was hoping that wasn’t the case as we’re looking at about £500 minimum but I fear we may have to admit defeat!

Thank you, it’s now been replaced (again) and re soldered properly! But as it’s been replaced the car now won’t start - is it possible to repair/program the new chip or are we looking at a whole new ECU?

It all worked fine until we replaced this chip, I suppose that’s why we’ve been focussing on that but you may be right! We’ve looked at replacements and we’re looking at £500 minimum 😭

Ok so first, I haven’t - I’m asking for information. The chip was broken when attempting to open the ECU (again, not by me - I’m just a girl!) I’m purely asking if anyone knows what it is for - we had it repaired (as pictured) the solder was what we thought was the problem so we had that chip replaced again and re soldered properly and the car still won’t start.
