Auto window open/close no longer works on my 2012 T5.1

[transparu]

Any suggestions welcome folks!

I have had the battery in and out a couple of times in the past few days. I've been rearranging a compressor under the bonnet and have replaced the original battery with a larger one. I've done no new wiring.

I've put everything together again and find that the front windows no longer lower (or raise) when I use the remote.

I expect the issues has arisen because the ECU has been without power and forgotten things, though I have previously had the battery out for varying lengths of times and not had the issue.

As I say, any suggestions welcome.

Thanks folks.

(Incidentally, is anyone interested in how I mounted an ARB compressor in front of the firewall, below the windscreen and above the engine compartment. I have a couple of pics.)

Well blow me down.

The battery has been back in for a couple of hours and all of a sudden the window open/close function is working again!

Makes me feel a bit stupid - but then again, there are plenty of things about this vehicle that have been unexpected.

If it makes you feel any better, I had the exact same experience a few weeks ago!

Can you post a pic of your compressor mount? I'm about to mount mine under the passenger seat (like Trakkadu). I've mounted a 135AH battery under the driver seat.

Hi Jonathan_k.
Thanks for the suggestion.
Have a look at a new thread entitled "Mounting a Compressor in a T5".
I have found out how to bore people.

In the manual there is a procedure to make it work straight away.
Otherwise it will return to auto after a few goes.
I just wait, myself.

Just pull the up switch for each front windows after closing and hold for a few more seconds that resets the auto function .

We were bush camped off the side off the Plenty Hwy the other night and had been stopped for 2 or 3 hours when out of the blue both front windows just fully opened. I closed them and they haven't done it since. I have put in down to dust and corrugations????

I've hit that a few times myself when tinkering with various things. Sunny has hit the nail on the head, roll the window all the way down and all the way up and it resets the end points (or something like that) and lets the auto function work again. AFAIK it's been like that since the auto function was invented.

Big Bug,
What a GREAT place to travel.
We went across a few years back whilst my T5 was still within warranty. Just as well - a bolt disappeared from a read brake caliper and the other one sheared. We were left at Atitjere (where we could call VW Assist). They promised a tow truck within 90 mins. It arrived 16.5 hours later. BUT, what a great road . . I envy you as I sit here right now planning a trip from Brisbane through bits of Western Qld, to Darwin and then down the WA coast, Adelaide, Melbourne and back to Brisbane.)
Safe travelling in whatever vehicle you are using.

Transparu, travelling in my 2014 T5 4Motion. So far the only problem has been self inflicted, turned too sharp coming out of a NP campsite and creased my sliding door and behind it on a bollard. Total stupidity on my part. Anyway you have a great trip because we are.

Still thinking whether to take out 2 more years warranty or not. $4,000 is a lot of money, not sure if it's worth it.

OUCH re the crease! It's an awful feeling.

I didn't take out the extra warranty though probably should have. Since my vehicle ran out of warranty I had to replace a windscreen wiper motor. (The O-ring seal had clearly been cut on assembly and water could get in, but not out. There was a huge amount of rust and corrosion in the housing but the Service folk wouldn't cover it - 3 m after the warranty ran out. Tonight I am battling trying to get the Turbo pipework back to working - as I have to replace the moo valve. Neither of these jobs would have justified $4000 though.


I posted on a UK site the issues I had under warranty:

Two "slam valves" failed, (serially) and were replaced under warranty. (These let air out of the vehicle when doors are shut but aren't supposed to let dust in. Mine were sucking huge quantities of dust into the cab.)

A front side light mysteriously filled with water and was replaced under warrantee.

TWO DSG gearboxes failed and were replaced under warranty, TWO.

The ?bearing plates above the front shock-absorbers failed and were replaced under warranty.

A bolt holding a rear brake caliper fell out, unbeknown to me. A second bolt then sheared and left me stranded in a most remote area. Tow truck and repairs were covered under warranty/VW roadside assistance. Caliper, disk etc was replaced. (Mind you, the tow truck was 17 hours later than promised and we were left in a most exposed situation, potentially quite dangerous, overnight.)

The left front door hinge broke and was replaced under warranty.

The windscreen wiper motor failed after 3 years and 3 months but the service agent wouldn't cover the issue. I bought and replaced a new one. On careful inspection it was clear that the sealing O-ring in the motor was cut as it was assembled and the break just happened to be in a position where it could allow water in but not allow it to drain. It was clear there had been water lying in the housing for a LONG time and rusting/corroding the innards. Electronics were fried.

The N75 turbo boost valve started mooing (3 yrs 10 months after purchase) but the service agent wouldn't consider it as a goodwill issue and I now have the pipes to rectify the problem.

FWIW,

Dave
