Hi would be nice if we can get a positive result for you, I honestly think you are not far off of cracking this one with the help of your friend, tell him to have a look at the live data for the throttle body as this should tell you if its the body or the position sensor. Steve.

Hi with extreme difficulty, a lot of swearing and possibly new clips, its normally easier to remove the rubber seal down the door panel and poke the wire inside but a lot of cars I have done lately have the strip glued to the metal bead held on with some sort of double sided cloth tape, don't be to afraid of giving the pillar trim some action as if you have the right set of trim removal tools it takes a lot to break it. Steve.

Hi Dale, from memory I think its part of the fuel vapour purge system this collects vapour from the system filters out any bits and re burns the vapour, all part of the wonderful emissions control. I think the reset will prove useful as my neighbour had similar symptoms on his old Polo after he had fitted a new throttle body it ran like a bag of nails until we readapted the new body, in saying that if it still wont run properly it probably is either the body or the position sensor, not much help but at least it will narrow it down, again from memory the position sensor on the peddle is plug in and play as its only a slave unit for the throttle body. Steve.

Hi buy smaller wheels with higher profile tyres, 17inch, thats the main function of pneumatics it subjugates the road noise from the surfaces, unfortunately people only want BIG wheels with lower profile tyres for which there is a penalty, normally extra road noise, anything under a 50 profile will exhibit this problem. Steve.

Hi will that is still eye watering, they are greedy bar stewards, its probably a two hour job and a bit of solvent/carbon cleaner and hot water, Audi extended warranties appear commercially branded Andrex and Cushelle, thats about all they are fit for, yes they are a dream car to own but everyone who buys one should swap their deep rose tinted specs for clear ones to to read the research on the problems these cars have with that system and the cooler its attached to. Steve.

Hi sounds like it still has air in it somewhere furthermore what diagnostic platform was used to clear the fault codes as sometimes VCDS is the only way to clear them. Steve.

Hi it means the low pressure valve that sits on top of the Low Pressure cooler is probably stuck and covered in a mixture of wet adblue crystals, £1400 is not reasonable for this job, the parts are about £200 aftermarket, when I say aftermarket I mean a VDO unit which is oe at about £160 then the transfer tube and clips and a gasket for the unit is about another £38, my opinion for what its worth is go find a good independent it will work out a hell of a lot cheaper, depending on your milage they might get away with cleaning your old unit, Audi are well aware of this problem on their Diesel engines. Steve.

Hi thank you for the pictures, I honestly think that the throttle body has the MAF in it but I am also concerned that the throttle position sensor on the peddle may also be at fault, its only a unit thats like old fashioned hand scales whereby the peddle pulls a spring arrangement within a sealed unit which pulls an internal resistor past a series of contacts which register the required position of the throttle butterfly to the throttle housing. Steve.

Hi if the car is a late 19 that would be the correct grade of oil to use, they started that with the later engines as its something to do with the emissions and the fact that the later engines run a wet belt for the oil pump drive. Steve.

Hi from all the parts diagrams I have looked at its right next to the airbox can you post a picture of your airbox and induction pipe its definitely there, the airbox pipework runs to the turbo not the throttle body. Steve.

Hi all vehicles are fitted with a MAF sensor its on the induction side between the air box and before the turbo normally a cylinder with a plug attracted to it, inside is a coated diode which is heated up and then allowed to be cooled by the incoming air this tells the ECU the temperature of the air as well as humidity, the ECU adjusts the injection accordingly based on the correlation of information from the MAP,MAF, and throttle position sensor on the peddle, all of these items need to be adapted when replaced to maintain synchronicity within the system. Steve.

Hi yes you do have to relearn a new unit, but it would suggest a wiring fault easy enough to check visualy, but if its done loads of miles it might just be better to let it go rather than drive yourself nuts and spend money trying to cure a problem that solved might only net you another £100. Steve.

Hi these cameras are a pain in the backside, Esther not a menu on the dash that disables it I have it on a new VW I have bought but at least I can turn it off on the dash, apparently they are affected by rod film on the windscreen and getting to hot, might be worth getting the update and the lens's on the unit cleaned. Steve.

Hi try LLL carparts they have a catalogue online the only bit you will needs your VIN code that should give you the part number, with regard to aftermarket as long as you don't buy Made in China they are generally spot on as Audi don't make the parts they buy them from Valeo or Febi or whoever sells to them at a preferential price. Steve.

Hi as long as you buy the slightly more expensive error free bulbs its perfectly ok, I don't think your interior bulbs are monitored anyway, could be wrong but if you use error free its not going to be a problem. Steve.

Hi its probably the instrument cluster going wrong, it will need repairing, contact ECU Testing they are experts at repairing these and its a lot cheaper by a mile than a new unit which will need recoding to the car. Steve.

Hi you did not mention if its back or front, my guess is rear as the cables tend to deteriorate behind the arch liner where the loom travels through the body work, joining them wont help as one is live and the other isa voltage pick up. Steve.

Hi I am pretty sure your bulbs are D3s which are readily available along with the ballast on eBay for not to much money, not worth changing just the bulb/ballast as if they are the originals they wear as a pair, personally I would do both sides, just done my daughters Q3 which has the same system, bulbs about £70 the pair, ballasts about £30 each and an easy job to do. Steve.

Hi if you get the DPF/EGR removed or deleted you will be forever getting dash warnings, no one has yet come up with a software that can delete the low pressure cooler which is I suspect the reason you are considering this route, please observe the following, if you remove the main EGR you raise both cylinder head temperatures as well as the turbo temperatures as the gas will be a lot hotter, this will also raise Nox1 emissions which the sensors in the exhaust stream will pick up hence the lights on the dash, I am pretty sure the code you have is p2002 particle filter bank one above threshold, the DPF is not itself blocked just the cooler, I have had a couple of these apart, also try and disseminate between the cooler and the main EGR which rarely gives trouble also might be worth looking at on site cleaning /mobile where they come to you and run cleaning solution through the exhaust system via the sensor hole on the cat. Steve.

Hi if its four wheel drive most definitely. Steve.

Hi Mark, the gearbox oil change is easy enough drain plug at the bottom filler on the side, the trick bit is making sure you undo the filler plug first as they tend to be a real sod to get out if you drain it first and then can't get the filler out you are up poo creek, the Haldex is a different matter as you need the kit with the filter and oil, a word to the wise Haldex pumps have a filter screen on the pump so its worth taking it out and cleaning, on replacement put new seals on the entry neck of the pump or it will leak. Steve.

Hi the rings are bonded to the unit, you may be better served going for used units as I should think new prices would buy you a seat on the next space shuttle. Steve.

Hi Gareth Jason would of known what was what, everything that could be useless or misleading all available from google. Steve.

Hi Eric, I totally agree with your guy, not done the job myself but watched it being done over about eight hours and the next day was the belt change, the rear most cam timing has to be spot on after removing the sprockets, get it wrong and you will end up with 100ks worth of scrap metal, I can see his train of thought, if it aint broke don't fix it, reading between the lines mechanic friend denotes either a favour or a very cheap labour rate, I can understand his reticence. Steve.

Hi I only changed over to OBDEleven as I now have a 2021 passat and apparently that is fitted with SFD software which blocks a lot of coding functions to stop people from activating things on the vehicle as you used to be able to do with VCDS,OBDEleven are the only outside diagnostic producers to have an agreement between themselves and VAG, so there software produces a challenge code to VAG main servers and if that code is accepted they issue a token to allow you to perfofm the function, therefore they have a record of every vehicle thats been interfered with which they pass on to the dealerships anytime a trade in reg pops up. Steve.
