Hi you need special tools to dismantle this you may well be better served buying a recon unit, by the time you work out the cost of thin wall through sockets and have you got a sturdy vice with a good soft jaw unit and then the four hours sweating to undo the unit its the cheapest option, even my local garage who are pretty enterprising wont touch a clutch change as you normally find the shaft seal behind the clutch is knackered and requires a complete casing strip down to replace. Steve.

Hi with the ignition on the voltage should not drop much below 12.3-12.7. Steve.

Hi its probably the rear gearbox tail shaft mount quite a common problem also check the engine mounts for oil leakage. Steve.

Hi for parts have you tried Charles Trent, Poole in Dorset they do a fine range of guaranteed S/H parts. Steve.

Exhaust gas temperature sensor there are normally two one before the cat and one after, both sensors have to tally up on reading whilst running if either is knackered it wont initiate a regen because it thinks the exhaust gas is not hot enough, I have had some EGTs that have been registering - 70 which means they are screwed, generally speaking 1psi sounds wrong as a new unit will measure at least 6-7 psi maybe more according to the amount of soot/ash in the DPF, I have always considered it best practise to replace any sensors to do with a DPF replacement as they all wear as a set, it must work as most of the cars I have worked on have never again had DPF issues in the last two years, monitor the EGTs on live data and when the car is raved the temps should climb rapidly, if your engine is Euro 4 you will only have one EGT, happy days. Steve.

ERM, sounds like it might involve money and effort.

Hi thats the problem with old Audis if nothing has ever been changed, the following will cause lack of regens bad MAF, bad MAP, weak DPF pressure sensor, bad EGTsensor, all of the above fail slowly and only ever throw a code when FUBAR. Steve.

Hi it might improve a little more as Audi quotes every thousand miles at least a litre is normal, not normal as the only other car I have found with this type of thirst are MINI and my niece ditched hers a while ago when she found out she was spending a minimum of £30 a month on oil, every later model Audi survives on losing about 50ml of oil between extended service intervals, also imagine what all that semi burnt oil will do for the catalyst and sensors. Steve.

Hi you have model within the years they fitted the wafer thin piston rings you can check on line to see if your engine was affected. Steve.

Hi sounds like the starter may be playing up, battery/starter being fine has anyone checked the starter voltage or the battery under load?. Steve.

Hi if you get the car scanned that will shed light on your problems chances are they are all caused by everything being disconnected when you fitted the new engine, did you get the ECU when you bought the engine as each engine will be programmed to its original as built ECU. Steve.

Hi thats the problem with trying anything ignition based, it thinks its being stolen chances are the immobiliser is fried, can't see why the dealer can't do it, when this occurs the can gateway will lock a lot of functions out, if you have VCDS you can reset at lot of this, never understood mapping out certain problems as it wont cure the root cause. Steve.

Hi nothing that a new trim and a couple of new lights wont cure but I bet the insurance will be going the whole hog new bumper, support bar, and lights a good few grand off the BMW insurance, should have got his face out of his phone, this is what happened to me last year, but faced with the rear dash cam footage it was a five nil job, including the hire cab just over £17000 all in, bet the !Removed! will do it again they are all the same BMW drivers. Steve.

Hi give it a bit of brute force, ABS plastic is very forgiving of a quick thump with the palm of your hand to locate lugs, its getting them off again thats the pain. Steve.

Hi the machine does indeed check for leaks via pressure But my A6 showed no leaks but at six weeks after it was done I was only getting cool air not cold so I dye tested the radiator and sure enough there was a tiny weep in the top right corner which was letting out very slowly so I had to replace the rad which was about £110 that cured it, if you look at the way the system is designed its a closed circuit therefore no gas should escape it only deteriorates after time and become weaker and wont do what it is supposed to because its full of contaminants, if you get it checked and there is no gas you have a leak, as for it running the pump all the time these systems activate via the relay which is why I suggested that, could be if the pressure sensor is feeling not enough gas pressure it is throwing it on to drive. Steve.

Hi just look at the new part and see where the lugs clip in, offer it up to the bumper and press in. Steve.

Hi on the plastic lugs that are sticking out at the bottom of the bumper? Steve.

Even the cheapest version of OBDEleven will allow you to do this, what price having your own decent code reader?, about £100 apparently, Steve.

Hi never been a fan of auto boxes, I have been told numerous times by my fellow cabbies that I dont know what I am missing, my manual had done over 270k and apart from a couple of oil changes was fine, if it is the Mechatronic unit and you need to replace it you will have to get exactly the same part number as you have already as they fitted about nine different types to these boxes, but there are companies that will refurb your own unit cheaply and guarantee the repair, the main cause of most failures are the raft of cheap badge engineered filters from Eastern Europe, they collapse early on in their service life and let all the cr@p into the valve blocks. Steve.

Hi if the clutch is engaged all the time it is probably a relay fault, if you have had it recharged properly you most likely have a pin hole in the condenser unit or the radiator. Steve.

Hi anything to do with master/slave cylinders the only choices are Sachs/LUK the right brake fluid is a must and the only oe equivalent is Comma ESP 4 which is a lot cheaper than Audi and wont rot the seals, no markings would suggest aftermarket as both the Sachs/LUK have there names on the castings. Steve.

Hi could be the Mechatronics unit playing up, get the car scanned. Steve.

Hi EGT sensors are very sensitive but the only way is to check their temp figures whilst running, chances are if you have a fair amount of milage and age they are all pretty weak, often asked how long an EGT lasts?, how long is a piece of string, just keep your mind focused on the real time readings on each sensor that will give you the answer. Steve.

Hi it is not your driving style, its a future fault the car had when it rolled off the line, my money is on the code being P2002 low pressure EGR cooler blocked this is described as DPF bank 1 particle filter below threshold, you do not need a new DPF just the cooler and its valve, as for remaps an elder statesman of this forum said we have more remaps on this forum than the ordinance survey, they are never any good. Steve.

Hi the anomaly with this is that sometimes it will show bank 1 because bank 3 is not suppling the correct information to bank 1 sometimes it is bank 1 but I normally always suspect bank 3 as this has the hardest life in the system you did the right thing pulling the plugs but if you have a reasonable diagnostic platform you can check the temp on each sensor in line and its usually the sensor that reads nowhere near the other two thats duff, I have even had it where the last sensor is reading -70 degrees, really!! the check for temp is available in the live data and if as you say one sensor made no difference I would assume thats the one.
