Battery replacement

[HYFR]

Fit a new battery on our TT on Saturday. £48 from TPS and 5mins work. None I this coding lark

If the battery has completely died before replacement then it will need recoding in the Battery Regulation module.
Just to inform the system a new battery is installed and the energy management system restores power to modules previously shutdown.

Get it done! No point leaving it Amar. Will definitely need coding work unless you can work out a way with jump leads to remove the old one whilst still wired up.

Mine always starts first time but didn't approx month ago which was strange. Took a second twist of the key. Then the Sunday getting it was sluggish starting, and then trying to move it back under car port after washing it wouldn't start.... and everything went blank and reset! Dash clock etc, RNSE blank! So the battery was at zero as I tried to engage starter. This was 7pm Sunday night and I had a service booked Monday 10am. I was shitting myself the battery was fucked and I wouldn't be able to get it started, but thankfully it started Monday after being left on charge using two extension leads. So I arrived at Audi and asked (begged) for discount for a new battery.

To give you an idea of the level of coding required, I drove to the dealer with no nav/stereo (code required), NOTHING working on the dash bar the fuel and temp dial - ie no speedo, rev counter, mileage, trip, no indicator 'clicks' or headlight on symbol - so I didn't think my indicators/headlights were working until I saw the reflection in the back of the car in front. Drove like <beep> too - revs died immediately as you pushed the clutch in to change gear. The drivetrain shunt was horrific if you didn't concentrate - had to keep your foot on the throttle slightly changing up. Also had the entire DIS taken up by a red oil warning. Knew the level was okay and it wasn't leaking, put in half a litre to be sure and left it idling for a while, set off for Audi and drove it steady to start with, temp didn't go above 90 so not oil pump related etc, clearly just battery related.

Dealer has coded everything back up nicely. Only thing I that doesn't seem to work is DIS current mpg, journey mpg and miles remaining on the DIS. Brimmed tank and reset trip but still no joy, so will have to google and play with vagcom I think. Lost all my long term averages, not that I ever really looked at them.

My advice is do it asap! If you can bridge the battery during the change so the car is always connected to power, even better.

I had to change the battery on my s4 but had no issues Ian, apart from the actual battery change. They put the battery in a stooooopid place on the s4 considering the size of it.

Yes its a whopper - and a very strange shape and size. Was quoted about £99 staff discount rate from GSF from a mate who works there last time I was in 6 months ago, so when Audi quoted £130 Monday morning I was happy with that, half an hours labour including any coding

CTEK has repaired the battery, starts instantly, had the interior lights, DVD and lights on for roughly 20- 30 mins with the ignition off, battery still at 100%. It's also not going down on shorter trips like it used to.

It's paid for itself, I may never have buy a new battery again.

That's great news... Told you the Ctek is a piece of kit...lol.
I recond mine last night as well... I do it once every 6 month there about to keep the battery in tip top nick.

[Mr V10]

Yes, you did. Wish I'd done it sooner.

[chunky79]

Great news mate.

[TechNick]

Good news, Amar.
I've been hovering over the buy button on a Ctek MXS 5.0 (with red button) for weeks now. Is this the same one everyone else uses and recommends?

I have the MSX-10 which is beefier than the 5.

What I've got, from Ultimate Finish iirc. It's all you'll need. Everyone with a 3+ year old car should have one. Surprised more don't know about these.

[TechNick]

Cheers. Well, now have one. It's actually a bit smaller than I was expecting, but not a bad thing as running short of space in the garage anyhow!

[skirs6]

Amar Did you use the battery connectors under bonnet or straight on the battery in the boot?

[Mr V10]

I used the ones under the bonnet.

[RS6chris!]

Looks like my battery on blink too!

Wouldn't start last week after a few days sat.

Sat today with just radio on for ten mins, went to start nothing.

RAC man to the rescue.

How much is a new battery anyone?
