Hi you would probably have to change the whole dash including the instrument cluster the whole of which will then need to be coded to the car then pray the BCM accepts the new coding for the immobiliser system, me personally I would live with the orange rather than potential failure and massive costs, its not like the old days when you took it all out and just replaced the bulbs. Steve.

Hi much as I hate to point this out if the throttle body has gone that will give you all sorts of problems starting and when it gets running it is probably running a default strategy which means yes it runs and moves but what you have is a get me home facility, surely common sense would dictate that would be changed first as if its not working properly that would throw up injector and air faults as the engine has no real control over either of the previous mentioned items, nearly all diesels use Total Throttle Position as the datum for air intake and injection. Steve.

Hi if the throttle body is faulty it wont move the butterfly in the unit to the start position [slightly open] when hot it may well work better as all the tar like substance is softer and allows movement try removing the throttle body and cleaning it, if that wont work you will need a new unit as they are also prone to stripping teeth off the plastic gear wheels in the control unit. Steve.

Hi don't bother with the expensive gizmos as it will only make the handling wayward, invest in a set of standard Avant springs as I believe the S Line is 25-30mm lowered from the factory, you will have to get it re aligned on a HUNTER four wheel tracking machine, change the front and rear springs otherwise it will dive at the front when braking. Steve.

Hi sorry to be the bearer of bad news but replacement is the only solution as these units are sealed and no spares are available, mine went the same this year I had to source a second hand unit its HID so its plug in and play, yours will need coding to the car. Steve.

Hi I think you answered your Question in the last sentence which equates to not a lot, all these engines were tested to destruction and when they break they take them to pieces to find out what caused the failure, they strengthen the offending part and up the torque/ BHP slightly, if it works well they just keep upping the power to way past the intended production run power, then whatever the engine has achieved up to 45% above the production Torque/BHP if it runs ok they reduce that figure by 45% to the production run power, thats your reliability factor, if you bear this in mind with the age of your car you are just putting more strain on an old engine thats made it this far with no real issues/wear and I bet if it all goes pear shaped and bits start failing he wont want to know unless it involves more money. Steve.

Hi could be a collapsing rubber hose holding the pressure so the pads are to close to the discs which would explain the fault not occurring when its been artificially cooled, I had it happen to me so I ended up replacing 1 calliper and both rubber hoses. Steve.

Hi Jon, as an awfully nice traffic policeman once commented about my cab callipers, painted red eh, makes it go faster does it, apparently he was one of the new breed that have to go on a course about spotting vehicle defects out on the road and told me all about it in great boring detail and when he finished I asked him about the reason why he thought I had painted my callipers, he didn't even come close so when I explained about discs becoming magnetic because of friction therefore attracting any small parts of rust that came off the calliper or disc centre and thats why the disc ends up looking like a 45 record, if they are painted no metallic debris other than what occurs naturally, all this came from a braking seminar for Lucas/ Brembo that I attended 30yrs ago, very glad they knew what they were talking about, they make the brakes. Steve.

Well done sounds a good option, if the code is for the unit it is most likely that thats buggered. Steve.

Hi thats the injector feed pipes, [the silver pipes] the black ones are rubber fuel return pipes these are prone to leaking with age, the other part coloured green is the cat with the oxygen sensor. Steve.

Hi you wont get a code up for the pump thermostat as its not monitored thats why they just boil up when it seizes shut, no warning other than the temp gauge going in to orbit. Steve.

Hi Jon you wont be disappointed, only other thing I would suggest is as you are rebuilding the rears clean the callipers off with brake cleaner and a Scotch brite cloth then mask off the rubber boots on the carrier pins and give it spray with some Halfords calliper paint, did that with my daughters Q3 when I did her pads and discs and it makes it look like new, still look great a year on. Steve.

Hi try buying the right part using your VIN/REG NO. then it will fit swapping bonded rubber parts is a disaster in the making.

Hi from memory you should have two stats one on the block and one on the water pump which is electronically controlled, its like a shroud that fits over the impeller and covers it when cold so the engine heats up faster, trouble is the shroud gets stuck wide open and can't start to close itself when the engine tells it the water temp is beginning to drop. Steve.

Hi Jon you wont need to replace the carrier bolts as these have a coarser thread as well as having grip washers on the bolt itself, as you will find out when you undo yours which requires a fair bit of grunt and a breaker bar, as for your wife's situation that is weird as they all come with the anti squeal pads already fitted you just have to peel the plastic backing cover off, not trying to teach my grandma how to suck eggs but another common mistake is copper greasing the backs of the pads, that will make them squeal as the idea is the rubber pad on the back with heat will attach semi permanently to the piston and support faces of the calliper. Steve.

Hi Jon, having run just about every combination of discs and pads over the last million miles I can honestly say that Brembo are excellent, both discs and pads BUT the ATE discs will last longer as the carbon content is far higher, Bosch pads are very good used with the ATE/Brembo discs, most other brands Febi/Mintex/Delphi are good but tend to wear faster, if you re use the old bolts 20nm torque is about right as these are stretch bolts and ideally you would use new bolts but absent new bolts you wont want to put to much pressure on already stretched threads, most kits worth getting have new bolts and a wear sensor as if you don't replace the sensor yes the old one works but fails in a short space of time leaving you with a dash warning light, you can phone TPS but have a Defib unit handy, then do the sensible thing and go on parts in motion web site or eBay I have just bought genuine ATE front discs and a Bosch pad kit with sensor cable and new bolts for £170, its all there if you search and the rear discs and pads are always cheaper by about 40%. Steve.

Hi finest upgrade is high carbon discs that are drilled on the front and just plain high carbon discs on the rear pad wise either Brembo or ATE, the biggest bonus will be achieved by changing the brake fluid using Comma dot 4 ESP, I used drilled ATE front and plain ATE discs on the rear of my cab the fronts now need changing but they have done 70k, grooved discs just eat pads and get bits of crud stuck in the grooves which wear the discs at an accelerated rate with no real benefit in braking performance, on the other hand drilled discs cool quicker as well as dissipating water on the discs during wet weather twice as quickly. Steve.

Hi you will need a suitable diagnostics unit which has the facility to put the car in to rear lining change mode, this is used when you have the car jacked up and the rear wheels off with the car in gear so it wont roll, switch the handbrake off and engage rear lining change you will hear the motor retracting the pistons, then with the aid of a beefy screwdriver inserted between the old pads and disc gently push the calliper piston the last bit back into the calliper the pads should be moving free now so its just a case of undoing the two bolts that hold the middle of the calliper to the main carrier these are attached to the slider pins which have a rubber boot covering them and allow the calliper to self adjust to compensate for wear, once released from the slider its a case of pulling the calliper away making a note of which side the wear indicator wire sits, you will have to replace the wear indicator as well as the pads, the wear indicator has the plug end in a slot in a metal bracket which you have to twist to release it so you can separate the plug and fit the new wire, make sure you fit the new pads the way the old ones were fitted that makes sure the cut out for the new wear sensor is on the correct side, take photos as a reference, clean the runners for the pads on the carrier with a stout wire brush and then coat them with a thin smear of copper grease and then mount the pads on the carrier and gently push the calliper body over the new pads, you will have to push the slider pins in a little to allow this, you must always use new bolts to hold the calliper to the carrier but in saying that you can get away with using the old bolts provided you clean the threads and use a blob of blue thread lock, do not over tighten these bolts as they will snap, nipped up will suffice say 20nm, once its back together give the brake pedal a push then take the car out of lining change mode then engage handbrake and replace the wheels, don't think I forgot anything but claim poetic licence. Steve.

Hi visualise kilowatts, more chance of poking smoke up a cats backside with a knitting needle, sorry but these things are pre programmed to do what they want when they want, if the car is being charged and the ambient temperature drops it will automatically turn on the battery heater and that sucks energy, these cars are a hard thing to analyse as the variables are beyond most mortals comprehension, thats why I have always run diesels as the patterns are more predictable with the change of seasons, example, my old Euro 4 engine used to give more power when it was colder but less MPG, slight difference with a Euro 5 engine colder more power and only a small drop in mpg, Euro 6 less MPG during the summer as the engine is permanently trying to run cooler but has to fight the effects of warmer air on NOX production, ergo more adblue consumption, now winter more mpg less adblue consumption as the ECU loves cooler air, I really wouldn't drive yourself nuts trying to second guess, it is what it is, welcome to new technology is it not wonderful, rule one if a salesmans lips move he is probably lying. Steve.

Hi worth getting a second hand unit with the same number and give that a try as these things are sealed and not very repairable. Steve.

Hi the pipes are return pipes for the injectors the bolt/nut looks like some sort of locking device for the injector and if you can get the old part out match it with the appropriate bolt/nut from any sales on eBay, stainless steel preferably it wont corrode, if its not causing problems leave it alone.

Hi the cooler weather will have a massive impact on the battery as all these batteries need to be warm to work efficiently therefore there is some kind of heating membrane around them which is powered by, yes electric, example being last year one of my fellow cabbies blew his beans on a Tesler which was fine during the summer 200 miles on a full charge, when it got blistering cold before Christmas he was only getting just over 100 miles, factor in the battery warming and the heater for the car and any demisting devices thats where your range goes. Steve.

Hi why bother with a remap when the new car will perform as well as your old car if not better, its all about how the torque curve is used on the existing map, I think you may find there is only a marginal difference in some aspects of the new cars performance especially when the newer engine has an extra 200cc which is a whole lot more to play with, go to the other end and in the early eighties Lancia did a Lancia Y10 three cylinder Turbo which at 1ltr was capable of over 105mph with a very respectable 0-60. Steve.

Hi the break will probably be in the rubber boot that runs between the door and the main body these are prone to breaking as the door is most used that side, pull the rubber boot back and inspect the wiring inside. Steve.

Hi it is almost certainly the mechanical part of the calliper that is driven by the EPB motor is sheared/seized, from my understanding and professional advice it is possible to buy the calliper minus the drive motor and providing the drive motor has not been damaged that should cure it. Steve.
