Hi,

I have a 2018 Audi Q3 1.4 TFSi. The fuel tank was damaged and has now been replaced. I have put 10 litres of fuel in the new tank, but I cannot get the car to start. VCDS is not showing any faults, but I am guessing that the fuel lines need to be bled?

Can anyone help? I can't seem to find how to get the fuel pump to run in VCDS or any info on how to bleed it.

Many thanks.

Fault codes or not, please always include a full Auto-Scan. If I want to try and look at wiring diagrams for this... I have no clue what I'm digging into...... I don't know what ECM you have installed.... all I know is this is some 2018 Q3 with some 1.4 and I'm a bit dim so I need a better starting point that the Auto-Scan gives.

Regards.

probably worth noting, the car was parked up with a dead battery for a few weeks.

Generally speaking, with gas engines, there is no real need to bleed the fuel system, it will take care of itself quickly.

I do see two things that look like they can run the lift pump in the fuel tank. Under [Basic Settings - 04] you will find:
IDE03999 - Drain fuel tank

And then under [Output Test - 03] there is:
IDE00219-ENG16746 - Fuel pump electronics

But I'm not so confident that will resolve your no start issues. I don't see the harm in doing the Basic Settings for maybe 60 seconds and then see what happens. If the car still doesn't start, maybe unhook the fuel line in the engine bay and feed it into an empty diet Dr Pepper soda bottle, do the Basic Settings again and see that fuel is actually being pumped up to the engine bay.

Is the battery currently in good condition?
Is there any kind of compression issues?

Hi,
Thanks. I have actually tried running both of those tests, but it would only let me run them once each for some reason? The fuel pump ran for 30 seconds and then stopped, but unfortunately the car still wont start.

The car has only done 1,700 so is virtually brand new. I've had a battery charger on it and set it to boost whilst cranking (battery seems ok on its own though)

Really don't know what to try next!?

I've just removed the black fuel line under the bonnet and there was quite bit of fuel pressure in there, so the fuel has reached the engine. the return white fuel line though did not have any pressure in? not sure how that system works if i'm honest.

I'm beginning to think the fault lies somewhere else other than fuel. What else could prevent it starting?

How is the compression? Do you have spark? If you spray a little bit of starter fluid into the intake during cranking, does it fire? Does the tachometer show RPM during cranking?

The rev counter is showing 400rpm or so when cranking, i've not checked for a spark as haven't disturbed anything around the engine as yet, the car has only covered 1,700 miles from new so compression cant be an issue - it cant be anything serious. As it is under warranty I might hand it to Audi dealer to take a look, they might be able to diagnose something my ross-tech software cant perhaps?

Not to be a Jack here... but how do you know compression is good? 1700 is just a number on the odometer, not an indication of compression. You've got an engine that doesn't fire, one must check the basics. Odds are it isn't the compression, but until you actually do the test with a gauge and get data, you can't confirm it is good.

Being under warranty why didnt the main dealer replace the damaged fuel tank? Must have been an impact or something. How severe was it? The fuel pump/filter sits inside the tank so have you reused the original? Is it 100% ok or could that be damaged? Too many unknowns..
