Caddy wiring

[ImNewHere]

Hi all,
We have a 2004 Caddy (300k) that had a warning light come up, the dealer said EGR and replaced it ($1,000+!!) and the warning light remained.
They then bypassed a wire to it as well, concluding it was a wiring fault. The warning light remains.
They maintain the valve would need to be replaced sooner or later anyway so it we are still out of pocket.
They have also pointed out that the insulation on the (engine bay) wiring is crumbling and that we should 'get rid of' the vehicle!
Should a ten year old wiring loom be deteriorating in this way?
Is this a known issue?
Is VW responsible?
Do VW dealers often 'bag' their own products in this way?
In my experience the wiring loom was there for the life of the vehicle, or is it a service part nowadays?
Is there anything in the service schedule that says 'check wiring loom'?

I'm no expert but I would have cleaned the erg valve first before replacing it. Obviously a dealer wouldn't do this because they make a lot more money off a part that can be brought online for $200.00 that they can then charge you $1000.00 for. ( I suspect they pay less than $200)

I have never heard of a loom needing replacing. Stands to reason they could perish over time but would be surprised.

I don't think 300k is that much for a TDi. Plenty of UK owners have done at least that with no real issues.

Every thing in your post tells me you should find another mechanic.

dealers will put crap on their products if they are at a loss to know how to fix it - especially if it's so far out of warranty that they won't get hit with a statutory warranty claim.

If you really think they are giving you bad advice then contact VW customer service

Is there nowhere else to go but the dealer?
