Polo 1.9tdi injectors compatible with A4 B6 1.9tdi

Post by ArthurMbambo » Thu Mar 01, 2018 9:54 am

Hi there just a quick question , I just found a set of Polo 1.9tdi injectors and am struggling to find reasonably priced Audi A4 B6 1.9tdi injectors and was wondering if they will work on my 2003 A4 B6 1.9tdi.

The part code is 038 130 073 AG . I have tried google not much there.

If you can't drive it like you stole it don't buy it. Life is too short to buy boring cars or worse trophy cars you won't drive.

According to this spares website it could work...

Audi part nr: 038 130 073 BA

the AG injector seems to be from a 74KW Polo so is probably not compatible

All PD injectors will fit any PD engine.

The problem is the "cc" of the injectors.
As vgti said, AWX AVF BLT ATL engines use the "BA" injector which is 530cc. (BLT also comes in the Seat Ibiza fr)

The 74kw polo on the other hand with the "AG" is off an AXR polo cross which is around 425cc.

U cannot have 3x 530cc injectors and 1x 425cc. That would be asking for trouble - the ecu is not going to compensate for a smaller injector therefore that particular cylinder will run lean.

So in other words, to avoid all the problems, do not put in an injector if the part number doesnt match.

Well i got a complete set of four and with the price of new injectors I was considering running them until I can get new ones. So is not a go or not for me as i have limited time to respond as I'm not the only one chasing them

Why dont u just recondition ur faulty injector?

If thats not possible then speak to a tuner about mapping ur car with the smaller injectors (if possible). I dont know of anybody who has done that. But, a straight swap with smaller injectors wont work as stated in previous posts..
