A diode is usually used to prevent voltage flowing back from a coil or a DC motor, if the BCM were damaged the issue wouldn't be intermittent. The starter needs a very good earth from the engine block to the chassis so I'm wondering if there's a damaged earth.

In that case there has to be a dodgy earth under the bonnet somewhere.

It's just a thermocouple, they generally work or they don't, 999 degrees suggests it's broken.

The clunk sounds like a bad solenoid, try replacing it, they're not expensive.

Suffix E is made by Eldor in Italy, I just bet suffix F is made somewhere else by someone else. The part itself won't have changed.

Yes, your charging system output is hopeless, 1V more than battery is no good, you need 14.4V while the engine is running and 12.7V from the battery when it's not running.

Of course there's gas, it's the gas pressure sensor, it doesn't work by remote witchcraft, it's exposed directly to the gas so it can sense the pressure!

Well I never, it seems the auto uses a legacy block from the earlier generation Polo, this kind of makes sense because the Fabia is a 9N Polo based car before the 9N Polo even came out. I stand corrected, I bet an auto BBY engine is the same block and an auto AUA probably as well.

There is absolutely no way VAG will cast a completely different block just for the transmission fitment, think of the cost implications alone.

No chance, the blocks are all identical, a BKY is a BKY, the starter operates on the flex plate rather than the flywheel as I said so you'll need the backplate from your old block as well which is what the starter bolts through to the bellhousing. The engine itself is entirely separate from all the transmission guff and will be the same whether manual or automatic.

The manual engine will work fine if you swap the clutch and flywheel for the flex plate and torque converter from your existing engine.

I understand and I'm sorry you're having a tough time, I wasn't trying to be rough but replacing the cam is a big job and you'll need some special tools to lock it all up. You also need to worry about why the cam needs replacing, it's usually down to the wrong oil used in an oil change, first thing you need to do is see how much metal glitter there is in the sump, if a lot comes out with the oil then you might be better off just swapping out the whole engine.

It's basically an updated PD100, as ever at 125k It's the clutch you need to worry about, the engine is bulletproof, ignore all the silly headline numbers and just make sure it's a clutch friendly map.

Look, I'm from sarf London, however dialect is a spoken medium, not written, we write stuff down so EVERYONE can understand it no matter where they come from. We get tons of foreign visitors here for whom English is not their first language so it is important to be concise and clear when communicating technical ideas. These are not conversations, those are for soshul meedyah. Ok.

Dude, just stop with the 'lol' already, this is a serious forum for serious advice otherwise everything just collapses into a clown show of slapstick idiocy where people deliberately give you the wrong advice just for the 'lols' so you end up trashing your engine. Ok.

I think this loophole is probably related to the small amount of actual virgin R134a in the cylinder, anything under 120ml is classed as a limited quantity and is probably exempt. When I said dangerous, I meant dangerous to the environment and have therefore edited my response to avoid misunderstandings from spitting literalists.

If you need to ask you probably shouldn't be attempting it, it's no laughing matter.

Look, there's a lot of righteous and officious guff being bandied about in here: https://en.wikipedia.org/wiki/1%2C1%2C1%2C2-Tetrafluoroethane?wprov=sfla1 R134a really isn't dangerous to the environment, the only reason it's restricted at all is its GWP and in the quantities we're talking about it's really neither here nor there. So quit it with the traffic warden mentality already.

Oh boy, I think this guy might be on the wrong forum...

Style over substance? Couldn't you just stick crap all over a wheel that does actually fit, make a sort of 'Blue Peter' version of a Lambo steering wheel?

Anything is possible, they're both VAG group cars after all, you should probably get a price for the wheel first and make sure you're sitting down.

More than enough.
