Golf mk7 / Re: Battery low voltage
« Last post by Guzzle on 11 January 2026, 12:31 »I can get a new battery from Halfords but wondering will they code it? The guys at VW said you don't need to do this but tbh not sure I trust them!
The following from Halfords website - Halfords Start/Stop batteries in some vehicles require the battery to be registered with the on-board computer system, so we strongly recommend professional fitting.
It needs doing so perhaps call the branch in advance and check.
Thanks mate, will call them. VW wanted £360 for a new one, maybe see how it is over the weekend and try a garage that I normally use.
Got my replacement battery supplied and fitted into my GTD back in 2021. They coded it too.
Almost 5 years down the line and no issues.

Golf mk7 / Re: Racingline or Revo
« Last post by ProtoCulture on 11 January 2026, 12:31 »So I can buy an SPS from anywhere at any time? It doesn't need to match my car, or have nay software loaded onto it? If that's the case it's good to know.
Sorry, I don't visit this forum too often, correct, the SPS only tells the the ECU to use setting 1, 2, 3, 4 etc, it doesn't store or know what the settings actually are. This is what REVO told me themselves.

« Last post by ProtoCulture on 11 January 2026, 12:28 »I changed my battery a couple of years ago as the Banner EFB was dying and my dashcam (parking mode) was putting too much strain on it.
Swapped it out for a Bosch AGM Type 096 S5A08 from Tanya Batteries. You can code via OBD11, basically you just need to 'tell' the car it has a new battery. If you have OBD11/VCDS its pretty easy.

General discussion / Waste gate adaption issues, failing for safety reasons
« Last post by Zaite on 11 January 2026, 10:52 »Hey! Hoping someone can help shed a Light on my issue.. So my old turbo went out and i bought a new renovated is38 from a friend and installed it, car drove fine after install for a day or 2 and then from no where the car shakes and limps when getting on boost
Realised i didnt do a waste gate adaption. So i set the voltage to 3.6 and it aborts the adaption for safety reasons. So i install my old accutator which i know worked before, but same issue. I hear the waste gate working for 3 seconds then it aborts for safety reasons
And i have checked the pivot arm moves freely when disconnected
Anyone got a clue where i go from here?..

Golf mk4 / Re: ARL Boostleak whistle
« Last post by bogwoppit on 11 January 2026, 10:10 »Did the smoke test also pressurize the system?
If not, you need to try something like this, and then go around all the joints squirting soapy water on them to look for bubbling

« Last post by Napalm on 10 January 2026, 18:09 »I dont know, i bought the car with the issue, however its top speed is only 121mph, factory its 137mph,
Update: ive had a smoke test done, reault was inconclusive, no smoke leaked out. Really stumped here guys
137mph are you dreaming :grin and any idiot doing that in an old mk4 deserves a slap
Cheers for that mate, looking for advice on to stop the whistle when the turbo kicks in lol

Golf mk8 / Re: Mk7 GTI spare wheel and tools into mk8?
« Last post by alland on 10 January 2026, 09:53 »I had the same experience trying to get a space saver for my Mk8 GTI - this after bursting a tyre on a pothole 60 miles from home and having to rely on VW Assist / AA to get me home.
I got a space saver with Continental tyre plus complete tool kit at my local breakers - or "vehicle recyclers" as they like to be known now. £60 plus VAT for the lot, and they even checked that it would fit over the front calipers!
