I'd love to say...it was easy, but I honestly I don't recall, he whole thing was poorly manufactured, built to a price, I've seen the same on more expensive cars
Not really made to be serviced. If it packed up, you just threw a new one in. If it's 20 years old and NLA, you have to fix it, or you're stuffed. I'll take mine down to Mr Fixit. Not too far away. I can't be @rsed to fiddle with it. Mine's made by TRW, interestingly, not VDO or somesuch.
2000 1.4 6n2, so the one before your Mk 4. I don't trust myself to dismantle it any further. Lot stuff to break. Off to the fixers, who seem to do a lot of fixing of VW and Audi's poor designs.
I don't think VW do anything else than visuals and specifications for electronic assemblies, the rest is contracted out, often to the best price. Porsche are guilty too, if my mate's Boxster is anything to go by. If you believe the press, that's what's causing them issues as they move into electric cars, their existing approach as a glorified systems integrator just doesn't cut it when the car is effectively a computer on wheels. Hence their investment into Rivian, to stop VW going thru a Nokia level extinction event.
They just want subassemblies built to their design. Interesting that the pod was made by TRW. Americans! Whatever next? Don't think VW are in danger of going bust anytime soon, although a mass move to EVs is going to come back and bite them all. Jaguar are about to commit commercial suicide with their battery-powered Barbiemobile.
So, I searched Google about how to remove the cylinder head for a VW type 2 2000 cylinder head...this is AI Overview reply. Remind me again how good AI is?
More Polo resurrecting. Cam belt looks fine. Good condition and red blobs suggest it's been replaced once already. Persuading the EPC light to turn off next on the list. Then some serious lube on the rear door locks, which will save me fortune in fuses for the central locking
I've found a basic £20 code reader can clear the EPC light on my Fox and my son's Polo but it will return if the fault is still present, or intermittent. The EPC on my Fox was irritatingly persistent, but I tracked it down to the Cam Position Sensor - I now occasionally clean the sensor face and check the plug connector.
Mine's a weird one. Once I've nipped down to Euro car parts, I'll tell you whether my cheapo scanner was correct...
Note easily removable top cam belt cover. Three clips and it's off, for a good look around. No need to remove half the engine to check the bloody belt
What model is your son's Polo? 9N? Assume it has central locking. Is it vacuum, or this new-fangled electric stuff? I suspect my vacuum pump has expired. It no longer makes the moo-cow noise when the doors are unlocked.
