Since we are throwing guesses in I'd go for dodgy earth strap to engine or body.
Yes this if its snapped or disconnected would cause all those problems.

Check the connections to the main maxi fuses located above the battery. One of the main live feeds usually has a bad connection and gets a bit hot.
whs the box may well have melted make sure if its this you also change the wire that goes to the starter/ alternator at the same time smile
Does this affect the TDi as well as the 1.8T? If so, thats doubly crap on VAG's part.

Yes. One of the main feed cables degrades causing resistance which starts to melt the fuse box hence lack of electrical power. Fuse box and cable require replacing.

Just had a call from the wife to say the family bus (Alhambra TDi) has just dies big style.

Suddenly lost all power + electrics. Managed to coast into pub car park with no power steering or assisted brakes. All readouts ie. odometer, trip computer have zeroed and nothing when she tries the key.

Green Flag have just arrived so we'll see what they say.

In the meanwhile whats the PH view?
Alternator dies in such a way that it has a direct short, had this with the volvo, AA disconnected the alternator, gave it a boost and followed me 4 miles home!

Or something worse...

The key to this is what the dashboard actually says, if it says nothing and is blank, they it is going to be power failure, so battery, alternator, main fuses, etc.

If the dashboard is really say zeros, as in 000000, then it is going to be the ECU and the dashboards are simply a display for the ECU these days.

Ok, sorry for delay.

Local garage recommended by a mate came out sat am and it started on his battery pack thingy.

He offered to take it on his truck to check it over and it needs a service and new rear brakes anyway.

He rang me sat pm to say it died again after starting. He checked the tank .... and its got petrol in it!

Asked my wife if she had visited a garage before it broke down she said yes, put £20 in drove out the garage and it dies less than 100yds down the road.

So garage is going to drain the tank fit a new fuel filter put 20l of diesel in it and hope it hasn't done any damage. Mechanic is confident as it didn't run for very long and only had about 5l in it when wife put petrol in.

Getting parts today plus sorting brakes and giving it an oil service. Also fitting new battery as its the original (03 reg.) and its knackered.

So thanks for all replies. Still can't work out why odometer zeroed itself.

Aye, I had to do it on my old vRS. Sadly after it had killed the alt...
