Vw Caddy 2k 1.9pd
I’ve got a vw caddy 1.9pd 2k (heavily based on the mk5 golf 1.9pd)
It’s quite modded
With mild cam, 80% injectors, bigger valves, heavier valve springs, GTB2260 Tubular manifold , 3” downpipe and exhaust, bigger air filter, oil 19mm catch can. Putting out about 280bhp and 400lbft

It’s started having a problem starting, the longer it’s left the harder the first start in the cold is any start after that is spot on. It also goes into a very rough idle and you can’t use the accelerator pedal! After 30 secs(some time less) it goes to a normal idle and works normal.

I’ve reconditioned the starter motor, new battery, new glow plugs (upping the glow plug time in vcds) changed the glow plug loom, new oem cam sensor, crank sensor. Nothing seems to change it the torision is at -1

Picture of engine bay for attention!

Any advice would be greatly received!
