Which bulbs did you use? Sorry, maybe you posted this already.

Clear the codes and see if they come back. Those codes most likely point to an air leak on the rubber plumbing between the airbox and the throttle body. They can difficult to spot.

Wait. You took the heatsink off the LED bulbs? They won't last long if that's the case.

Very nice. A lot of car for the money. Shame about the colour. 😊

I can't see a good clean out with a hose doing any harm. It's just water.

Doesn't sound like a battery drain issue, otherwise your battery would go flat with the boot closed sat overnight. Sounds like your battery is dead.

Glad to hear you seem to be making some headway. That's some weird s**t you got going on. Hope you get it all sorted.

Very carefully check the rubber boot between the MAF and the throttle body for a split. You'll need a mirror and a torch. Most likely the cause.

Ah, not for pre face lift.

2 to 3 ohms would be terrible. It should be 0.3 ohms or thereabouts. It is hard to measure though, so maybe a limitation of your meter. Have you looked for water or corrosion at the ECU connector?

That's a LOT of unrelated errors, maybe as you say due to a sporadic ground fault. There is no way that all of those individual items will have failed. It'll be symptomatic of a power or grounding issue. That's my guess anyway.

Yup.

Engine fuses.

You mean gloss black or fake carbon fibre? I really don't get that fake stuff.

Not really that close to staffs I'm afraid.
