Warm start problem HELP!! 1.8 8v dx engine

Hi Iv loosing the battle with my hot start problem. Starts on the button when cold but splutters and misfires when trying to start from hot, it only lasts a few seconds then clears and runs sweet. 

So far Iv had: 
New genuine injectors and seals 
Fuels pressures checked (all ok)
Full set up fueling set to 1.8 co 
New non return valve (check valve) 
Replaced the ends on vacuum pipes 
Plugs,leads,rotor arm,cap,coil,ignition module,fuel filter 

Is there is any other things to look for? I thinking of stripping the metering head to check for build up of crud 



Any help is much appreciated 

Could be the accumulator, from a www site below and its about the only bit that you haven't replaced. I'd also unplug the 5th cold start injector incase its adding extra fuel that's not required?

If yours is a 84+ Cabrio the DXs have extra gubbins for idle stabilisation and other stuff that the tin tops don't have. More to go wrong when 30+ years old…….

Fuel accumulator
The fuel accumulator maintains the pressure in the fuel system for a certain time after the engine has been switched off. When the engine is running it serves to deaden the noise of the electric fuel pump. After the engine has been switched off, the fuel accumulator maintains the pressure in the fuel system in order to facilitate re-starting, particularly when the engine is hot.

Next time she won't start when hot you will need a glamorous  assistant to help. Undo the bellows on top of the metering disk get a magnet or some pliers to lift the disk up.
Next get your assistant to try and start the car as you lift the disk - if she starts then it could be something as simple as a sticking plunger, but most probably the metering head is worn out. Dano had the same battle for ages.
funk-star does exchange metering heads or there is a company that sells refurb kits.

True! 4 years I was battling with the problem and my unglamorous assistant Dj Ev had to push me before we set off to Getmany… Not that he ever mentions it!

In addition to the replacement metering head from funk-star , I also 'hoovered' out the petrol tank and made sure that any rust (and there was a lot) was taken out. A new filter was also put on and a second hand fuel pump that the garage had in stock from years ago. 
Touch wood, the problem hasn't reoccurred. 

Right the problem is still there. Since my last post iv replaced the fuel pump and the accumulator.  Is doing my head in.. Need to try another metering head but can find one with the same part number.  Are they interchangeable? Can I just use anyone as long as it's from a dx engine code  
Here's my part number 

Here's the other part number 

I had the same problem and it was my metering head it would run rough and miss as soon as it was changed all was good. Contact funk-star aka mark @classicvw.co.uk or Kmi Bosch refurb them in letchworth.
Best of luck.
