    2014 B8.5 2.0 TFSI Quattro AGM battery replacement

    As I said earlier if you were to replace the battery in the car with another one with the same part number the only thing that woukld be different is the BEM number. The action of changing this is what resets the battery management. changing one digit in the existing coding is all you have to...

    2014 B8.5 2.0 TFSI Quattro AGM battery replacement

    You don't need to code the battery if you are replacing it with one that is the same capacity and type as the original battery. The only thing the guy would do when coding it is change 1 digit in the BEM code as the original and new batteries are both Varta and both AGM and both 92Ah. The new...

    Low profile tyre(s)

    Stock wheels are 8.5J . That limits the width of tyres you can fit . If you look at a 30 profile 255 tyre that gives you a tyre that's nearly an inch smaller across the diameter. so drops the car 0.5 an inch and the wheels will look smaller and Ride will be harsher. A fairly pointless excercise.

    S4 All Season Tyres

    Having a tyre that is designed to work in all conditions means it has to make compromises so won't provide the ultimate performance possible when compared with a tyre designed to work as a summer or winter tyre. Saying that some of the best all season tyres are better in snow that tyres that are...

    Programming the battery charging voltage

    Is the battery in the car the correct size?. If it's an exide than it's not the original battery as these are usually Varta items . VCDS will allow you to alter the battery chemistry and capacity of the battery and the charge voltage is determined to a certain extent by these values.

    Hi Bobby, Not sure you have seen this only posted up around an hour ago. Maybe you could contact Jamie and arrange a little OG battle.

    Bobby Singh A4 3.0 TDI build thread

    Seen a post on FB a few weeks ago where one of these was used on a MK1 TT. The factory item does allow some front to rear movement of the prop shaft where these seem not too allow much movement at all. I think they initially made these for RWD cars which possibly don't have the same amount of...

    3.0tdi CAPA limp mode

    The Darkside sensor looks different but I suspect does exactly the same job. As I said earlier they are resistance sensors and a quick check with a multimeter will usually identify if it is faulty. If you can disconnect that sensor and it drives reliably I would get it down to Bobby and get some...

    Did you try measuring the resistance across sensor. Good news that the car is driving again. Had a look on Fleabay, you coulkd pick this up from Birmingham. https://www.ebay.co.uk/itm/203726178591?

    3.0tdi CAPA limp mode

    It's just a platinum RTD thermocouple and gives you temperature post cat / Pre DPF . I wonder if the issue is related to the DPF regen and because that sensor is specific for that process it's disabling the limp mode some how. Try disconnecting the DPF pressure sensor electrically and see if...

    3.0tdi CAPA limp mode

    As stated above a bent piece of wire or plastic straw inserted through the pre DPF EGT sensor hole should enable you to determine if the DPF is till intact. Or borrow a small Endoscope camera from work, I am sure they have plenty. If the DPF has been gutted the weld lines are usually on the back...

    3.0tdi CAPA limp mode

    Hi Ben, If the DPF was very blocked I wouldn't have thought the intermittent nature of your issues would be showing and the EGT readings would be a lot higher. It seems to me that you may not have a DPF present if the DPF pressure sensor is showing 0 and the last regen was 120K km ago.

    3.0tdi CAPA limp mode

    Looking at previous logs I have made on my A4 MAF readings at Idle with no boost are around 420-450mg/stroke dependent on the idle rpm whether it's hot or cold. Normal hot idle speed is around 650rpm. If you have 1 bar boost then you would end up with around twice that reading. As the air intake...

    Are you 100% sure the car hasn't had any petrol in it. Does the diesel feel diesely. As I said earlier quick test is to see if it is combustible with a match . Diesel doesn't burn at all. Of course only a small amount away from anything else flamable.

    3.0tdi CAPA limp mode

    Have you checked the EGT sensor readings to see if they look sensible. This is one of the things that is quite often mapped out . Fuel pressure checks between specified and actual. You could spend a lot of money and time randomly changing sensors out and still not sort the issue.
