So my car has been fine however since hitting 109k ive had few issues but today was the worst!

I was driving and gave it some beans when it was on correct temperature and my car started to misfire bad, limp mode. I scanned it using (car- pal top don) and it came up with Cylinder 1 and 2 misfire, several misfires and fuel pressure plausibility, the car engine was shaking badly, white smoke coming from the exhaust and really smelled of fuel.

This evening i changed the cylinder 1 - 3 bank 1 sparkplugs to new ones and cylinder 1 sparkplug stank of fuel and was bit wet.

I did a cold start today and took around 4 seconds to crank/start and the car was still running horrible the radiator fan was on full speed.

Is this my HPFP failing or something else.

These where the codes:

DME - 21/04/2026
0029f1 - fuel pressure, plaubility
0029cd - combustion misfire, cylinder 1
0029cf - combustion misfire, cylinder 2
0029cc - 0029cd - combustion misfire, several cylinders

Since changing replacing new spark plugs on cyc 1-3 these where the codes. cold start engine but turned off after 10 seconds as it sounded horrible
DME - 22/04/2026

0029f2 - High pressure system, fuel pressure
