Vw transporter T6 broken down and will not start

[craigt6]

Hi looking for some advice,

So my T6 2016 shuttle broken down on my wife. She said coil light started flashing she lost all power and soon as got to low speed it cut out and will not start.



Things checked so far,
Scanned no codes.
Checked cambelt looks ok.
Checked the HPFP regulator functions ok no metal filings on mesh.
Changed the fuel filter.

Where should I go next any help is appreciated.

Cheers Craig

Got any access to vcds scan data?

Look for cam and crank RPM signal.

Look for fuel rail pressure build up under cranking.

Does it turn over ok?

Will it try to start if you give it a wiff of easy start?

When you changed the fuel filter did the old one appear full of diesel?

Not necessarily but I read it’s a sign if there is metal filings in there the pumps on it’s way or bad. I’m no expert by any means just trying to eliminate what I can to cut the garage time down if I can’t resolve.

Good evening Craig, what engine is in your T6 ? with regards to trying easy start, have you got an aerosol can of brake cleaner ? If so try spraying a stream of that into the air intake, whilst getting someone to crank the engine if you can, PS remove the air filter element first if you can, brake cleaner is a good substitute for Easy Start

Hope this helps
Craig

Hi Dell the engine started with spray but cut out. Please any advice

Is the coil light still on? - if so I am surprised you don't have any fault codes, and you may need to get it scanned with VCDS.

Did it cut out after you stopped spraying? Or cut out and won't start again even if you spray more in?

When you use the spray, all your doing is checking the integrity of the engine to rule out serious engine issues. It will only run for as long as it is fed the spray.

Your fuel pressure is reading low on the above data you have. Was that data taken whilst cranking the engine?

Hi Kev

Yes cuts out after stopping spray the data was from cranking.

Vehicle still currently not starting any help appreciated.

Hello Craig, does your diagnostics show any live data ? Is the ECU recognising / reading your ignition key transponder ?

Have you got a spare key you can try ? If not have you got someone with a more in-depth diagnostics system to read your vehicle ?

Hope this helps

Ok, so the engine is mechanically sound.

Like @Craig B has said. You might need a better diagnostic machine. Seems strange there are no codes stored considering the coil light was on.

Is there any history of recent repairs or problems with the van?

It shouldn't be the immobiliser as that won't cause the engine to breakdown when it's running. Once running, you can throw the chipped key away
