catalytic converter light and EPC light (solid) - advice please

[prcurrie]

got a call from dealer and VW Assist today...
one of the pistons is burned, but they are still trying to determine the cause...
meanwhile, will likely get a Europcar loan car today, will be a nice change after Nissan Micra for the last week...
I'm thinking this will likely take a while to get sorted.
cheers

Bugger mate - another quality issue to add to the ever growing list with the Polos

another call early this morning...

it's going to be a replacement engine, so I guess that's me out of the Polo for a further couple of weeks...

Hopefully the replacement engine is a CTH

Unlikely. They'll probably just rebuild the current engine and replace any parts that need to be replaced.

Well, they actually said a complete new engine...
Also, when I spoke to mechanic last week, he indicated that the first car (Golf TSI) they replaced pistons, on the second Golf they replaced whole engine, took a week from order....so maybe VW is taking the safer option...i for one would rather have a new engine than replacement parts.

Ok well I'm sure it varies from dealer to dealer, but I know most people on this forum who've got their engines 'replaced' due to oil consumption have actually ended up with rebuilt engines with the same engine number.

ok, thanks, will probably ask dealer/VW for something in writing...what do you think?

I'd ask the dealer seeming they're the ones doing the work.

Fair chance Tigga1 that all they will do as Alex pointed out is replace certain parts but its not just pistons, you will end up with a new bottom end. They will retain the head etc and probably just give it a good clean to get rid of the carbon build up.

Interesting that a piston has been torched, there has always been suspicions around the safety of the factory ecu program and how the fuel delivery changes throughout the rev range on these motors...

So how does one provide proof of fuel quality?!?! Do I have to keep all my bloody receipts??

Total BS...
