Hi it sounds like thats best practise as if its not broken why change it and possibly run into problems you did not previously have plus the bonus of having two new spare servos, you will probably never need them but its always good to have spares. Steve.

Hi UDS is a more aggressive scanning mode that is more suited to Canbus data software systems, with regard to unplugging things I can see why people don't do it as when my car had a new clutch master fitted we unplugged a fair few connectors on the GEM module above it to get the GEM out to give access to the clutch master cylinder, the car was dormant and had not been run for about eight hours but when I plugged in to see if there were any faults BINGO every service we had disconnected from the GEM had a one time lost contact code the ignition was never on but the only thing I can conclude is all systems are monitored around the clock even when not in use. Steve.

Hi don't take any notice of the letters at the end of the part number as these are denomination for the year of supply, there are many who believe this letter to be critical, its not and a prime example of this is the glow plug on cylinder three it has a pressure/knock sensor built in, mine went sideways before the bank holiday and kept throwing an EML with a code for an implausible signal, it was on its way out, the part number for our cars is 03L 905061G, the plug they sent me was 03L 905 061K thats the supersession number, it fits, it works wonderfully and no more EML, I rest my case, BTW the same plug is fitted to the A5 A6 and several Volkswagen models. Steve,

Hi any idea of a price? Steve.

Hi unfortunately that particular design was doomed to fail shortly after the surround seal gave it up and let in water, if you poach the Audi part number off the listing you can Google it and see if its cheaper elsewhere. Steve.

Hi Roy most informative video, I particularly liked the soldering/saddering part where his industrial size soldering gun was flying about and melting bits of the shielding on other wires and the total omission of how he found which wire was what I heard something about a multimeter at one point. Anyway I digress the reason I said to save the long coding was that it gives you a reference point if you change the units and they don't want to play, chances are all will be fine as long as you know if your system is UDS/Non UDS as the procedures for cycling the calipers are different for both also make sure you have a battery charger or donor battery connected to the jump posts as sudden voltage drop will kill your hand brake control module, also he did not mention he had left the battery connected while mucking about with wires its a dodgy hobby. Steve.

Hi I think you will get exactly what you want with that finish, just stay clear of acid wheel cleaner as that will kill the paint in record time. Steve.

Hi if you get the car scanned the fault code should tell you which part is malfunctioning. Steve.

Hi disregard the previous post as I have just looked at mine and its the same as yours apparently the pipe with no connection measures the atmospheric pressure against the the realtime pressure from the pipe that is connected to the DPF via a long metal pipe, I think you are probably right about the DPF issue as the variables for that code are massive anything from boost control valve, clogged turbo vanes, boost diverter valve, they all lead to one thing a build up of crud, the cheapest option is give it a bottle of Wynns EGR cleaner and give it a nice long run down the motorway if that sorts it the crud in the emissions system is your problem, from a quick research even Audi have problems diagnosing this one. All these cost cutting solutions they come up with just create more problems than they solve for the end user. Steve.

Hi as I said both pipes should connect one to a metal pipe before the DPF and the other to a metal pipe after the DPF, its in there somewhere, have the splash pan off and have a look from underneath. Steve.

Hi in the old days you had a pressure sensor as a separate unit on the cylinder head therefore if you cut down on the extra machining and put the thing in one of the glow plugs its yet another manufacturing saving and according to the Gurus is a more efficient until it goes wrong, I have very rarely come across this before but apparently Vauxhall Nissan and a host of others have changed over to the same system, this means you have to buy four ordinary glow plugs to get the other three normal plugs unless you want to buy the whole set which includes the SPECIAL ONE for a shade under four hundred quid. Steve.

Hi basically its telling you that the pressure switch is reducing the gearbox function due to lack of oil pressure therefore its put itself in to a protection strategy so the gearbox won't self destruct due to the leak, the drivers mirror adjustment fault could be down to corrosion in a connector block but I would definitely get the gearbox leak sorted first, as for the bang I have no idea. It would have been wiser to post the codes and reports first as they are real time info and not a description from a personal perspective of what happened, it cuts out the guess work. Steve.

Hi get it scanned for fault codes that will tell you what part is playing up. Steve.

Hi both pipes should go to the DPF one before and one after the DPF that is why its known as a pressure differential sensor as it measures the air pressure going in and the pressure at the other end going out, thats how it knows when the DPF is blocking, check to see if either pipe is broken as that will be your problem. Steve.

Hi it could well be gear oil as the box is struggling to maintain enough pressure to drive the car. Steve.

Hi TBH that is not a bad finish, I would not stick my nose up at that considering the age of the vehicle the stove blacking is obviously doing a sterling job of keeping the corrosion at bay, its got a sort of retro gothic look. Steve.

Hi if there is nothing wrong with the old callipers I would of given them a good going over with some 120 grit oxide paper then a good clean with rubbing alcohol before painting, and yes just use the existing servo units. Nice job with the painting. Steve.

Hi guys got an EML up today so I dodged home and got me code reader which hurled up P13D600 internal pressure sensor cylinder 3 implausible signal, new one on me but it turns out cylinder three glow plug is a bit special as it has a cylinder pressure sensor built in to it, the rest of the plugs are about twelve quid a go but not number three thats so special on its own its between £100-120, only putting this out as an accelerated milage model like mine 122,400 miles these things are beginning to occur. Steve.

Hi thats correct but you gave no clue as to whats wrong with the old ones so I was working on the assumption that one or both sides had some sort of failure electronically, if you don't have to replace the actuators all good but whatever you do put the rear brakes into service/pad change mode before fitting new units and above all do not unplug the drive motors or you will loose the existing coding, then you will have real problems. Steve.

Hi various car designs are only the tip of the iceberg, what about all the badge engineered spare parts including VAG brake pads a few years ago, real value for money they were as when tested at MIRA they only took an extra sixty feet to slow down from 50mph and the sad gits at Eurocarparts had sold loads of them, but I think theirs came with a set of rosary beads for the impromptu prayer meeting when braking. Steve.

My word chaps its handbags at dawn

Hi Kev if you think about it logically, ECU Testing is the better bet, worse case scenario is it is scrap for which they only charge a small fee, if its repairable !Removed! marvellous as this comes with a guarantee which you can beat them with if it fails in short order, if you DIY the job and it still won't work you will never know why because us mere mortals don't possess the test rigs they have. Steve.

Hi if the part numbers are the same it should be a straight swap but save the long coding from your old unit just in case. Steve.

Hi they will need recoding and adaptation but if you have Vagcom its doable just make sure you save the original long coding as that will get you out of the cr@p if it starts going sideways. Steve

Hi yes plenty of retrofit units but they are expensive and the LEDs used normally fail quickly. Steve.
