Hi, I’ve changed 3 out of the six injectors on my v6 Audi q7, is it possible to find out, if the others have been changed, before I owned the car, using VCDS?

You can check whether the IMA codes printed on those injectors match what's in the respective Adaptation channels in the ECU, but beyond that, I don't know of any way, and even if they match, that doesn't mean they haven't been changed.

Do you mean it’ll show up those that haven’t been coded in? I’ve coded the three I changed. I’m just looking at the bolts and injector tops and some look quite clean, others don’t. I’ve had the car 3 years and changed 3, definitely thinking about changing the rest, unless they’ve been changed before. I thought it might tell you the date when they were coded

You will not get a definitive answer to that question without consulting previous owners.

If 3 went then the other 3 will go - that you can be sure of !

Thanks, I’ll change the other 3 asap I think. I went into limp mode towing our caravan on the M5 not great, to say the least

don't they have a date of manufacturing written on it?
Means nothing !! Could have been remanufactured / refurbished 4 times since birth

if the date is after for far before the birth of the car, i'm pretty sure it's not the original ones.
