Hi the fact that you have only found repro units should be a clue and at the end of the day as long as they work is anyone really going to notice that they are not oe. Steve.

Hi I think your model may have the sensors in the rims, only way to find out which wheel is the wrong un is to get the car scanned. Steve.

Hi there are two level sensors under the back seat the problem one is the main tank sensor which involves taking out the seat squab and undoing the sealing cap and replacing the unit. Steve.

Hi I don't know what you are on about, changing the sensor is a joy, the bolt holding it in is nearly always seized and then you have the fabulous prospect of getting the new one in at the right angle without disturbing the reluctor ring on the crank seal, take in to account the swear box bill, buy the mechanic a beer. Steve.

Hi the oil sensor is common I had two on my car the oil is probably coming from the sump seal mine did that too, they also delight in leaking from the front crank seal and the cam shaft seals, they also leak from the oil cooler and the rear crank seal thats why there's a hole where the gearbox meets the engine to let it run out and spray down the under tray and cross member for the gearbox, you will always be playing chase the ace with leaks, rocker cover injector seals are another source of oil buying habits, I swear Audi have shares in Quantum Steve

Hi there is only one VCDS, I would recommend the single VIN version if you intend to keep the car, the OBDEleven is a lot cheaper but of late I have found this system will do what you want but only if you have the Pro subscription which is over £100 a year therefore the VCDS represents better value as once purchased its yours with free updates. Steve.

Hi thats better I think a good spray with WD40 and then try twisting it, try left and right gently I have a feeling the end that goes in the filter cover has some sort of locking tabs. Steve.

Hi can you post a picture of the new sensor both ends

Hi I think you are suffering from the latest Audi bright idea, make the sensor and the filter cover one piece. Steve

Hi if it stands for a long time the only thing that deteriorates is the pad sensor wires easy enough to replace and cheap enough aftermarket. Steve.

Hi not come across this before, is it a grey import ? and can you get the part number off of the old unit as that may shed some light. Steve

Loads of stripping down therefore it would be wise to replace everything down there, you won't want to do it twice, also you will need to adhere to any torque settings for bolts. Steve.

Hi probably the oil cooler, not a nice job. Steve.

Hi I think you have solved it yourself as a broken bolt won't maintain uniform pressure on the gasket therefore water will escape. Steve.

Hi its obviously in its early stages, the reason it is slipping in higher gears is because of the torque load in higher gears, it used to be the old way of testing the clutch, find a nice hill and change up to early floor the throttle and if the clutch was good the engine would labour, if not it revved up, I would get it checked ASAP as when the clutch slips it creates a phenomenal increase in gearbox temps and cooks the rear crank seal which is a whole different story, having had it happen to me I can say its not a good day out. Steve.
