Touareg '06 Exhuast Workshop

Open up the old one and you will most likely find the plastic gears are stripped inside it. Carbon buildup is the root cause though yes.

I'll be doing that just for the tinkering of it!

V6 is not one of VW's finest moments it turns out!?

Because the 8 year old part failed? Disgraceful eh?

Plastic gears = planned obsolescence maybe?

Btw George, not slagging here. Just saying.

I would say it is just a consequence of the way car manufacturers do business.

VW don't make the throttle body themselves. They ask Pierburg, Siemens VDO and a couple of other companies to give them a price for the part they need. Chances are whoever can supply it for the lowest price gets the contract.

So obviously that being the case you are going to end up with plastic gears rather than expensive metal ones that will last forever!

The Guvnor

To be fair - from what I have seen and heard now the V6 could be better built.

It's not bad by any means but there are known issues and most it seems are down to poorly designed parts.

Who made the parts is not really relevant to me - throttle valve goes I think less of VW etc.

VW does have more reliable engines than the V6.

So, plastic gears = planned obsolescence then?

Expensive repair costs, at least...

I realise that planned obsolescence has to happen to keep the market turning, because the customer base is not infinite. I just wish they would stretch the time to obsolescence a bit more...

If they would just do that, and not charge mad prices for these essential parts (that should have never failed unless totally abused or not serviced on time), we could all get along fine with each other.

Plastic gears, if properly enclosed and lubricated, and not stressed outside their parameters should last 'forever'. If the manufacturer of the vehicle/machine took a calculated risk and skimped on the cost, they should be prepared to accept the consequence of failure of those bought-in components.

Customer loyalty is invaluable, but the temporary bean-counters do not realise that, and they are not employed to do so.

In today's world effiency is the key. Lower fuel consumption = lower emissions, and while cost will be a factor on deciding to use plastic I suspect weight of the component will be very important in deciding who wins the contract to supply the most suitable part.

I'm not convinved about this at all. For a couple of weeks I filled up at the M1 Applegreen near Castlebellingham and my 1.9 TDI Jetta ran like a pig and the economy dropped way down. Work now has me elsewhere so I've filled up at Clairehall Tesco a couple of times and ran a bit of Petrol through the system and the car is now flying and I'm back to 56mpg on a combined journey. I'll be giving Applegreen a miss in future.

Is running petrol through a diesel good for the motor?

The issue is the indy would buy the part from VW.

I think the 1st one bought back in 2012 from VW in Chester was a reconditioned one!

You think George these kits are not up to much?

Maybe worth giving them a call, they most likely have a set rate for the job.
