Hi Andrew please find what I have discovered, there are only three sensors not four and I pretty certain that the diagnostics you are using is what's at fault, each platform relies heavily on the software writers interpretation of a fault and through experience with different platforms I have come to the con elusion they must have had a few beers whilst writing the software. Steve.

Hi if you are happy with the rest of the car I know it means more money but go and consult your nearest wheel and tyre specialist and ask if they do a tyre that is different and may solve your problem, if not try the old how much will I get trade in for my stuff against a set of decent 17inch wheels and tyres, find out what your wheel offset is and go looking on eBay, factor in that you may have to have the wheels refurbed and new tyres but you get to keep the old wheels for when you get the car, multiple variables with this problem. Steve.

Hi its quite a common problem mostly the rubber bit rotting out but if I were you I would take heed of the term not seriously weakened, get under the back clean the alloy bit with a small wire brush and then give it a coat of Waxoyl that will keep the rot at bay for years, did mine when I first got it 2019 and they were still good four years later. Steve.

Hi gary, which light, more info needed. Steve.

Hi it looks like time to broker the deal for other wheels or back the car. Steve

Hi you wont get a definitive answer until you have had the vehicle scanned and that will give you the codes to get it fixed. Steve.

Hi Golden rule check all fluids every two weeks, I think you have a leak somewhere and are getting air in the system visually check the hoses around the throttle body and EGR valve as they are prone to leaking also check the hoses under the inlet manifold, the thermostat housing hoses as well, easy to spot antifreeze leaks as they are stained the same colour as the antifreeze even when dry. Steve.

Hi got a new microcat coming Tuesday I will have a look on that and see if I can get a schematic diagram. Steve.

Hi try eBay or put in a request in breaker link.

Hi Gareth, try TOYO PROXES my mate has just fitted those to his wife's golf and reckons its like driving on air compared to the Continentals he previously had and also reports back the wet grip is phenomenal. Steve.

Hi the Bridgestones would probably work better on the A6 but the denominator is that the A6 is a far heavier car. Steve.

Hi in that case it could be the one underneath as the exhaust goes under the bulkhead, weird thing is on my VCDS when mine started acting up it was the top first sensor that I changed, the one further down the pipe is a sod to get to. Steve.

Hi I think you will find the sensor you have marked three is actually number one as its at the beginning of the exhaust stream next to the adblue the others run downstream. Steve.

Hi to effectively put out the light you will need something like OBDEleven not exactly expensive but very efficient this will also let you change the inspection due. Steve.

Hi the trustworthy solution is get in touch with ECU Testing and get it tested, no problem there is only a nominal charge, if there is a problem they will inform you with a repair price. Plus being as its your original unit its plug in and play. Steve.

Hi its the thermostat on the water pump that controls the engine temp the other one before the the heater is the one that controls the cabin temp, if that one is playing about all your hot water flies through the bypass system. Steve.

Hi the upper picture is the clip to get, they are a pain to fit but not a problem if you have the right tool about a tenner on fleabay, good idea cutting the pipe back as long as you don't go nuts with it there should be enough slack let to get it connected again, can't believe the price of that pipe, if you get any length problems get a section of copper pipe the same diameter as the inside of the rubber pipe and then you can make up the length by doing a cut and shut further up the pipe it just means three clips instead of one. Steve.

Hi I would say its the O2 sensor, easy fix and relatively cheap to buy. Steve.

Hi its most likely the thermostat sticking open so I would change that first if that wont work change the matrix its only worth using Valeo/Febi as a lot of the cheaper ones fail, might be worth flushing the system as the silica bags in the coolant tank rupture and block the matrix, so try the thermostat and flush first you may well save some money and a lot of grief. Steve.

Hi on the original post you quoted 50m from the the sea is that 50 miles or metres, I did not at any point say you don't trust Brembo just trying to fathom out why I have never had the same problem other than sporadicly as I live seventeen miles from the sea and if I get what you have the rust is gone within 900yds with no detriment to the longevity of the discs, if you factor in road salt over the winter months and all the various acidic compounds in the water when it rains its a no brainer the discs will along with everything else under the floor will corrode the time table for this is heavily dependent on the quality of steel used in making the bolts and even the plastic trim clips holding the under tray and wheel arch liners on they eventually harden and fail, I only use high carbon discs with no small success, with both ceramic and carbon fibre disc the downside is the extra time they take heat to the level where braking efficiency is optimum, this is caused by the fact that both mediums are 50% better at losing heat than carbon steel and should realistically used on cars that are driven aggressively, so in essence you only have one of two choices. Steve.

Hi no camshaft sensors are different but from your faults and seeing as you have changed the the throttle body I would be looking at the throttle position sensor on the pedal. Steve.

Hi have they scanned the car for fault codes, if so what were they, confused by the list, high pressure and low pressure injectors not heard of them. Steve.

Hi all E11/E9 discs are rigorously tested to get this E mark therefore they will have taken the surface rust in to account, the corrosion you are suffering wont make the discs rot any quicker than anybody else's , I use ATE/BREMBO on my car and occasionally get rust spots or complete film rusting over the whole surface and I still get 70k out of them, it seems from my perspective that you are trying to build a case to buy what is basically a very expensive piece of kit just so your discs look nice in the morning, you make no mention of track days, if thats what you intend doing by all means go for it. Steve.

Hi good shout, I have no doubt it would be good policy to purchase some of No 22 which is the clips which will give the pipes more longevity, shame whoever put the pipes on used jubilee if they used the clips you wouldn't have this problem as the pipes look good apart from the crushed mounting ends. Steve.

Hi hazard a guess on what's leaking out it looks like a power steering pipe judging by the colour of the leak, I would also assume its been replaced before as it has a jubilee clip and all pipe clips on Audi are of the spring variety on armoured hoses as this allows for thermal expansion and contraction, jubilee clips don't and if overtightened muller the integrity of the hose as when they expand the rubber has nowhere to go. Steve.
