Hi the one in the picture is it, the sensor you were sent looks like the one that would be by the crank pulley the sensor you have has the plug socket integral in the sensor. take the old unit out to get the part number. Steve.

Hi the best thing to do is ring an on line company Parts in motion they will be able to tell you exactly what size discs you have from your REG/VIN Number, they only sell on eBay but will be able to give you item number for discs that will fit your car, and are probably 40% cheaper than Euro car parts, I use them a lot and I have never had a bad experience. Steve.

Hi Andy, used loads of peoples differing software and found shall we say quite a few variations on codes the cheaper they get the more lethal they become bit of a minefield really that was why a few years ago I bought VCDS, that definitely nailed it every time, in saying that the new cab I have is a VW Passat and my VCDS wont go near it as everything is protected by the new SFD system, I wont go in to any detail because its long and boring but suffice to say that post 2020 you can't do a blasted thing on the car without having the right system, thats when I bit the bullit and bought OBD Eleven pro, yes you have to buy tokens to perform some functions but its about as as good as VCDS but without the hefty price tag, VCDS latest multi vin software is nearly £700 but OBD came in at £104 with a token bundle its a lot slower scanning as its bluetooth but it gets there and gets you what you need, the diagrams are from my new system, the good news is the part number for all three is the same. Steve.

Hi no such thing as a crank sensor without a wiring connector otherwise it wont work, you have to find the remains of the original wiring the sensor is normally by either the crank pulley or where the gearbox joins the engine. Steve.

Hi I agree with Gareth/Steve the electric steering rack draws about 60amps when operating if its not getting any continuity that will give the symptoms you have. Steve.

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.
