So after just 30k miles the Alternator gear and the coupling failed, unexpected because VW stated the coupling and the gear should be changed at 60K-70K miles. Ordered them today, 85euros both.

Is that on all models?

[big jon]

is it an easy DIY fix or is it dealer only on the R5

Seems an important point to note that the alternator should not be removed from its mounting bracket or basic alignment will be lost

This is dependent on whether the vehicle has a diesel particle filter. The replacement interval is 93,750 miles for vehicles without a diesel particle filter and 112,500 miles for vehicles with a diesel particle filter.

How on earth can a DPF in the exhaust possibly affect the replacement interval of an alternator? Someone's having a laugh surely?

Extra backpressure slows the combustion pulses making the coupling last longer.

That's the only obvious reason I can think of.

93,750 miles with DPF versus versus 112,500 without [and no apparent time limit the rubber? and/or synthetic? coupling either] does seem odd.

Yet another reason for a good remap and DPF delete!!

I usually try and remember the various engine sizes on the original Minis and the years they were introduced . . . . . . .

Yes, the f****** rubber coupling.. Just 30K miles.. Actually its the gear that fails, and rips of the coupling.. Interesting design for VW to get money.. At least I am not buying it from them now, found aftermarket parts.. a lot cheaper.. Because I am far from home, and the shop hasen't got the bearing, just the gear, I am going to take the AC compressor gear and coupling and put it on alternator, just to get home.. And when the coupling arrives in the shop I'll put it on AC..


Oh and you get a whistling noise when reving, thats the sign of a duying gear and ripped coupling..

[mstar]

I'm wondering about mine now I will look out for the sound.

[Touareg MNE]

The sound starts 5-7 miles before the failure.. Not before that.. Can't inspect it, change it.. Just to be sure..

[mstar]

How many hours labour is it? Might do it with ny service

[Touareg MNE]

I changed the AC compressor coupling and gear in about three hours.. A good mechanic will do it in one.. Both, one and a half..

[mstar]

Is there a way to see its condition? Or we just have to wait for the noise? Not sure if this is as common ad the prop shaft issue in tregs ?

[NoobyT]

If I owned a car with these couplings, then I would treat it like the centre bearing on the prop shaft - a simple maintenance item at, say 60K/5 years for the shaft and, say, 90K/6 years for the couplings.

Sounds like a £300 bill with the parts, labour and VAT at an independent.

[Touareg MNE]

I was about to replace them on 50K miles, but it didn't last that long.. A mechanic here quoted me 30E for labor, thats in total 110E..

[mstar]

is the parts available only from Dealer? is it termed "the alternator coupling" or something else?

did a quick search is this what we all talking about?

Another engine out job on the V10s I take it?
