Hello! I am new to this forum so apologies if this is posted in the wrong section. I have done some servicing work on my 2015 (65 plate) Audi A3 8V 1.6TDI yesterday. Part of this service involved replacing my leaking injector seals and rocker cover gasket. I completed the job, injectors looked mint when they came out, just a tiny bit sooty but that wiped up fine. Injector seals all replaced, rocker cover gasket replaced. All re-fitted. All fuel lines, return lines and electrical connections re connected, and all connectors labelled before removals as well as injectors to ensure they went in the same place. However, on the first fire up. The car initially ran on all 4 cylinders for around 10 seconds before the engine knocked and shut off. Which is fairly typical when breaking into the fuel system, as the same had happened when I changed my fuel filter a few months back. On the next start ups, the car now only runs on Cylinders 1 and 3. With 2 and 4 not firing. Unplugging injectors 2 and 4 has no change to the engine running condition, but only then throws an injector code if you unplug them. So far I have tried bleeding the fuel rail multiple times and everything seems well bled. I even attempted swapping Injectors 1 and 2 over. This still resulted in Cylinder 1 firing and Cylinder 2 not, which leads me to believe this is not an injector failure. Any help or advice at all would be greatly appreciated. Thanks in advance!

Ok, the A7 went if for its first MOT. It failed! Two tyres Dunlop sportsmaxx- one tyre bulge on inside and other split - both front tyres BTW. Oh and my number plate was 2 mm out with the spacing. :( One of the gearbox ECU’s failed the one that operates the auto handbrake malfunctioned ( you can guess the cost for that) lucky its in warranty Audi Garage carrying out MOT spotted oil leaking from between the Engine and Gearbox - said it would need to go back to the Audi garage I bought it from. So What Is Leaking then? Long story short and a week later back to the other Audi Garage. They had it for over a week as i refused to accept the car back unless it was resolved and fixed adequately, in fairness they agreed and carried out the required work. Said they couldnt find any oil leak, mmm, but said they wiped the understray and around the engine but could find any oil - WTF. They did identify the following and this follows in line with a stories i heard a while ago with older models when major engine damage was the outcome. 1st - They noticed the Adblue seals were leaking - so they changed those....TICK! 2nd. They also noticed the seals (4)around the injectors were leaking diesel....TICK This may sound pretty standard the way it was reported to me over the phone. They say they carried out a 200 mile test drive and couldnt see any oil leaking. So i have had the car back, on the basis that I drive it for another 600 miles before returning it for its next service.
