Tappet bleeding

[Beetle_Juiced]

Hi folks

Apologies for this question being in English, my Deutsche is not too hot I'm afraid

I have the famous Mexican noisy tappet issue on my 2004 Mexibug and have read a few things about the remedy. I have tried everything except bleeding the tappet, so just wanted to confirm whether you do indeed have to remove the engine to do this as stated on the tech section of this excellent website, or whether it is actually possible to fish the tappet out using a flexible rod with a strong magnet on the end?

Thanks in advance, here's to a future of quiet beetle driving!
