I remembered I had Autodata on an old tablet, looked it up and was the wrong diagram I was using !!! and the belt went strait off the generator strait to the first pulley, not to the power steering and air con first like I was trying to do lol Thanks for everyone's replys

Yep, this is why I'm so baffled by the fact it disappears! Will get it on a proper diagnostic machine - but first I have a rather bad oil leak I need to investigate... Will post an update if/when I figure out what's causing this smoke issue! Thanks Al

Fixed it. Relay holder was sat in water and had dissolved.

ebay or a breakers would be the best route

Hi the sensor will either be down by the crank pulley or at the back of the engine in its own recess where the g/box joins the engine about half way down on the r/h side looking at it from the front of the car. Steve.

Hello Darwood, Varta and Bosch are reputed to be from the same factory and simply branded accordingly. To all intents and purposes, they are one and the same battery. Exide are reputed to be good. Energiser?? Not seen these as car batteries, but seem to be quite prolific in the cheap domestic bulb market and for domestic dry cell batteries. It could just be be me, but I associate that make with budget quality. Kind regards, Gareth.

Hi I can't see that buying an AGM battery will be any advantage to you in view of the cars age and assuming it is not equipped with stop start, the charging parameters are lower for the lead acid unit except when the temperature drops, then you have a problem as your existing set up generator may well rise to 15v, that will toast a very expensive AGM battery where as lead acid is far more capable of absorbing overcharge and still being serviceable, AGM will charge up to six times faster than a lead acid unit but won't tolerate overcharge, there lies the problem the charging systems on your car and newer are about the same but the BEM systems are different as the built for AGM system is highly sensitive and won't allow overcharge, I have also seen on this forum where one of the members bought an AGM to replace his old battery and caused himself all sorts of problems with weird faults, this is because you can't code an AGM unit to the older BEM so it can't work out why it can throw the worlds supply of voltage at the battery virtually unrestricted, this is because AGM has a much lower resistance to charge which is why it charges faster, in essence your $ will be much better invested in a top quality lead acid unit. Steve.

Hello Mussa, This would be typical of a below par battery. It may resolve itself with some use, but if it’s still running on its original battery then it sounds like it would benefit from being renewed. A personal viewpoint:- I’d be much happy to live with a non operative s/s system than living with it, so it wouldn’t bother me at all - I would see it as a bonus. Kind regards, Gareth.

Hello Darwood, I’ve always used Varta/Bosch - their 4 or 5 year warranty grade. Fortunately, we are blessed with a number of on-line battery retailers here in the U.K. Canada-?? Just a thought :- 16 year old vehicle needing an AGM battery -? Kind regards, Gareth.

They can be just as costly to run in repairs mainly with air suspension issues and electrical gremlins. Having a look through this q7 section will give you some ideas

Yep I'd say incompatible. You'll need the q7 one

You might be looking £650 ish. That's what I paid for my a6

Hi I have come across this many times with different vehicles, Ford for example can be read with just about any generic software for codes with varying degrees of success until you go into them and start trying to alter protocols for various functions then the ECU goes into protection mode an shuts down the Can Gateway and enables the immobiliser to protect the car because it thinks its being [jarked] stolen, with the manufacturer specific software it recognises the entry elements for the Can Gateway and won't mind you fiddling with it, excellent intuition unplugging the MAF because when it was rebooted it gave it something else to worry about, your system is very good but for reading codes on different vehicles, my garage I use has about three different Snap-On units but if he ever needs to readapt anything that is a bit exotic on a Ford he uses Forscan. Steve.

Sounds an electrical.fault. How old is the battery? As old batteries can cause all sorts of electrical issues. Especially if the alternator isn't charging it?
