Hi if you have the later edition of VCDS that won't allow static regeneration but should have the facility to regenerate while driving, check the the readings on live data for the EGT sensors and the DPF pressure sensor also check your soot and ash loadings. Steve.

Hi seen a fair amount of these with the same symptoms go through my local garage, asked them today and they said 06-09 the TFSI engines were notorious for this as the oil pump drive is taken from the balance shaft which lives a rather precarious life as its under constant vibration from the engine, this over time causes oil pump wear on the pumps drive shaft thus the intermittent pressure light, if it was the later engine the whole oil pressure system is controlled by two pressure regulator solenoids and two pressure sensors that send different signals as the pressure rises and falls over a drive cycle, yours is less complex as the pressure sensor is in the pump and not in the oil filter housing which is why for your yer they do a pump conversion, yes not cheap or a conversion to the earlier 1.8 oil filter housing which has the pressure sensor built in, don't take my word for it have a look on YouTube for the conversions, I sincerely hope it is just a pressure sensor. Steve.

Hi its not a pressure sensor its the oil pump drive shaft rounding off through wear/age back then they all used the same pump and hexagonal drive shaft. Steve.

Hi its not the gearstick squeaking, its the linkage on the side of the gearbox. Steve.

Hi its at the back of the engine in between the gearbox and the engine, can't miss it as it has a wiring connection its only possible to view it on a car lift with the splash guard removed. Steve.

Hi why don't you source another unit and ask ECU testing if they can convert the donor unit information from the original unit, from what I remember this was done before by another member. Steve.

Hi its the pixels gone, so you can replace it [expensive] or send your unit off and get it repaired. Steve.

HI it could well be the front brake hoses have had it, had this with my daughters Q3 put new callipers on and the same thing then I changed both front Flexi pipes and it was all good, being as the brake system is diagonally split if both fronts are hanging on the backs will do the same because the brake pressure is not releasing because of the front pipes. Steve.

Hi I really wouldn't bother because I have very little faith in that being the answer, as in they are repairable, there is no way to get the internal parts you would require and times effort and expense its better to replace them when you consider how cheap aftermarket packs are, Steve.

Hi if its an ULTRA its a poxy job and bear in mind if its auto it will have two of them as one is for the box. Steve.

A7S it is then, the other number is too long to be a VAG code.

Hi not necessarily I think your fan motors are on the way out, brushes probably and if you look at the age of the car they have not done badly, would suggest a new fan pack. Steve.

Hi from memory the top picture and I think its down below the plug packs second one from the front, other engines pre 2010 have them at the back of the cylinder head, to check you have the right part go on LLL carports put in your VIN and search engine parts for VVT solenoid that should give the right part number to shop with, they all have this system but most brands fit the solenoid in to the camshafts BMW vanos being a prime example they all misbehave at some point they either rattle like on Alfas or just clap out. Steve.

Hi why did he give you the readings engine basically cold, waste of time that one, the only thing I can assume from the differential readings is that you may well have a hole in the DPF core the readings with 33% soot should beat least 4psi and rising to above 7psi at 2500rpm, canyou supply the history of the vehicle as you have owned it as we seem to be bouncing from one subject to another between non working fan pack to headlights, all the readings you require can be had from your VCDS go to engine when its hot! go to subsection live data, you will be given a scroll down menu of everything you want to test just tick the box by the item and it comes up on the left hand screen. Steve.

Hi you will need a funnel thats the easiest way, loads on eBay to fit your vehicle. Steve.

Hi it will have at least two EGT sensors one will be located before the DPF and the other after the DPF both can be monitored on live data via diagnostics, the EGR is also monitored via diagnostics, cannot see it being the EGR as if thats stuck open it would be trying to regenerate constantly and have lots of smoke, what pressure reading did you have for the DPF if its high you have a blockage, did the cleaning man give any figures for for the soot and ash loadings as that would be your first port of call followed by EGT sensor readings as if one is reading stupid temps the car won't regenerate, this is also caused by faulty DPF pressure sensors as well as MAP and MAF sensors that don't correlate, do you have any diagnostics as without that capability you will only keep throwing money at the car and possibly never cure its problems. Steve.

Hi no cooling fan no regen, if you fix the fan and it still won't regen its either an EGT sensor or the DPF is full of ash. Steve.

Hi this seems to be a regular occurrence with later A3s a lot of victims were never told that the car is a mild hybrid, yes I bet you really wish you had your old car, I just think its a shame that Audi still trade on the reliability of their cars which is rapidly becoming a myth, we are talking late cars with a retail provenance. Steve.

Hi is it diesel, if so there could be several causes for the loss of coolant, and does is run adblue ? Steve.

Hi its a lovely car, my daughter had the diesel version up until recently which I loved, easy to service and as its a Volkswagen engine the parts won't be too spiteful and are plentiful, just don't get involved with the main dealers unless you have to,[wallet drain]. Steve.

Hi UNK is an abbreviation of unknown which the BEM will accept. Steve.

Hi that video is pretty much bang on just pay attention to putting in the correct AMP hour rating and if your new battery is not on the list just put in brand UNK that solves that one and if you are fitting ac stop start battery its called a fleece which is German for AGM. to get rid of all dash lights turn the steering from lock to lock a couple of times that clears them. Steve.

Hi had this problem with the A6, Audi own the patents for the clutches and literally have a stranglehold over LUK even though the clutches are produced in a vast factory system in eastern Europe and as with everything if you create a shortage it drives up prices, first clutch £1200 for parts, second clutch two and a half years later there was no availability for six months and had then gone up to £1900 for the parts, fortunately I never had to buy the second clutch but am really pleased with my Passat which when that needed a clutch it was how many do you want and came in at £750 inc parts labour and VAT. Steve.

Hi from the extensive research I have done it would appear most brands have their own problems with various models be it timing chains inlet manifolds and injectors none of which happen suddenly and completely disable the vehicle on a motorway, however Audi seem to excel at making cars that just stop wherever they see fit I would conclude that the slide started with the ULTRA models that are diesel and various petrol models before that, in the case of my car ULTRA they k,new they had problems with the DPF system but would never admit it, they always put it down to driving style or bad fuel, basically the blame was always attributed to the owner not the car, move along a bit and we now have their version of a hybrid wonder what marvellous excuses they can come up with, the lack of embedded codes is because of the software design which I feel was probably done on purpose, when I consider the amount of older cars I have scanned most of the Audis had redundant codes that were maybe five or six years old and irrelevant I think they rush these things through to keep pace with everyone else, the alternative is full electric but if you look at the depreciation levels because of the building mistrust of the brand your average etron is worthless after five years. Steve.

Hi as I said could well be multiple factors but my guess would be the VVT solenoid as if thats not working the acceleration will be slow as the oil pressure won't be via the solenoid altering the valve timing when you give it beans, but I would recommend a scan as that would show a valve fault on live data. Steve.
