The injectors on the rail are 06A906031BA would they be different to the stock ones on the APP engine?

EDIT : Looks like they are the same https://www.onlinecarparts.co.uk/bosch-1150389.html

Injector (BOSCH)

Fuel Mixture Formation:Petrol Injection
Static flow rate at 3 bar, medium N-Heptane [g/min]:217

Then the injectors being maxed out wont make a difference in another mao. They may map it better. It depends whos mapped it 1st and if theyve mapped it properly or just turned the fuelling and turbo up

So it went in and when I went to pick it up I was told it never went on the rollers as it was running lean so would melt the pistons....I needed to buy bigger injectors as mine (0280155897) were only 217cc and it needs 310cc with the KO3S.  So I said I had the injectors off the car with the ko3s and when I did a part number search they were compatible with the APP engine.....he then told me without a remap they would melt my pistons. So I asked him to check part number of the other injectors....which he did......using eBay.....and used eBay to show specs of mine....both showing 217cc....so he then went go the draw to get his aum injectors that would solve my problem with a remap....guess what.....same part number as my spare injectors (0280156061).....which eBay told him were only 217cc!!! He then looked elsewhere and everywhere said both sets of injectors were 310cc...so will be fine with the ko3s...They started going on about the fuel pump being the issue then. Im lost now as to what to do. They showed me VAG-COM block 032 showing correction of 1.9% on idle and just over 20% under load, I haven't had chance to do my own log and they have left the N75 unplugged to keep boost down to save my pistons from melting.....it all seems a bit too much like they really wanted it in to get mapped so I don't know if they are that great. I have got a fuel pump to pop in it and see if that makes any difference to the fuel correction but I'm not hopeful

Id take it somewhere else. Weak fuel pump will drop the fuelling down as the pressure will be lower. Id have thought that if pump was on way out it would be noisey.
The fpr on the other hand id swap for another 3bar one or a 4bar for a little more fuel. (What ive been told. Never tested though)

I can believe the aum and app engine have same injectors because there both 150bhp
The auq may have different injectors but i think there what you have as spares maybe?


It does sound like they wanted to get a bill out of you though and maybe sell you some injectors.

The APP is 180bhp. I have a spare 3bar fpr and now a fuel pump although the spare is 1j0919051c not 1j0919051h but I believe they are both the same. Would anything else cause it to correct fuel that much?

Well swapped FPR and the cone filter for standard air box/panel filter but VAG-COM is still showing its correcting at 4-7% idle and 15-22% on long figures so its running lean.......yet im only getting 200 miles out of a full tank so its definitely using too much fuel....what is going on?

no i plugged the N75 back in and VAG-COM was reading the same so think they were just talking rubbish to sound clever.

How do I check the Lambda?

Car is really popping through the exhaust, it sounds like its close to spitting flames if im honest.

If its popping its over fuelling. You can cycle the lambda.
Or if you live data you should be able to check co levels and such.

This is a sh!t explanation. Haha
