Definitive guide to injectors reqd
 

I realise it doesn't take much, but I'm very confused! I have a noisy injector in my 2006 D5, which comes and goes so I want to change it, which when it's bad sounds like a bucket of bolts! I have identified (long handled screwdriver) that its number 4 for sure. Mind the others are relatively noisy too.

I happen to have 5 working ones 'left over' from the 'new' engine I had to install due to the lifter disaster. What I'm after please is some form of definitive guide not to installing them (fine with that) but what to look out for to determine if one is 'good' or 'bad' and how to set them up in VIDA once that's done and its all installed.

I've seen that earlier versions had a number in a ring on them so their flow rate could be identified but all of mine are missing such info. Mine seem to have a sort of QR code thingy. I have no idea how to determine which is which and then I have no idea how to programme their flow rates with VIDA.

Would really appreciate your help chaps!

Short answer is there is no definitive procedure across the board.

Longer answer is that some injectors are plug and play, some require an ECM recode if the Class number is being changed, most don't have Class numbers, some require pairing to the car and some require a dealer only software download.

Luckily, there will be one definitive procedure for your exact car which will be detailed in the injector change procedure listed in Information >Repair >Removal, replacement and overhaul >Engine and Mountings >Fuel system in Vida.
If it says download software part number xxxxxxx you will need to visit a dealer.
If it doesn't say that, just follow the Vida procedure.

If your car has been read by Vida just click on it on the Vehicle Profile screen and Vida will automatically only show the parts catalogue, technical data and workshop manual for your exact car.

If you leave the vehicle profile blank and use the search facility in Vida it will show all possibilities for all cars which will obviously create more confusion.

Thanks Simon. That makes sense.
One other question then. What's the Vida procedure? Is it listed somewhere?

Already answered above.

Ahh. Thank you :rolleyes::teeth_smile:
