deo.... Hi the Turbine variable blades are sticking on the exhaust side and are unable to maintain there position or if its a vacuum controlled boost sensor the diaphragm may be leaking, easy way to check is give it tin of squirt down the intake trunking turbo cleaner if that improves it its the vanes sticking if not its probably the actuator on the turbo. Steve.

Hi hopefully as a lot of them are only interested in getting the soot levels down [easy] using any proprietary DPF cleaner the ash is near impossible to clear with anything like that, I constantly get to read cars where the owner says that the DPF has been cleaned a couple of weeks ago only to find the DPF is nigh on its limit for ash which wont leave a lot of room for the new soot load therefore it does one of two things it either keeps regenerating the reduced space or wont regenerate at all as the forced regeneration process will set light to the car as its protracted and will overheat the DPF and probably set the DPF pressure sensor alight which is quite common on the 2.0 litre engines, I have come across this before where the garage has cleaned the soot out and re zeroed the loadings with the ash still in there, when I tried a forced regen the DPF after 15 mins was glowing red and I had to abort the process which caused chronic oil dilution so adding more problems, I have trialed all known ash dissolving compounds on the market and if the ash is anything around max, THEY DONT WORK the only way is have the DPF off and have it professionally cleaned, from that you get a flow certificate before and after and you have the certain knowledge its clean, the ash forms large brick particles around the edge of the core inside and the only way to remove these is chemically clean the unit and then bake it to break up the ash the final process is a reverse flush under pressure which removes it because it goes out the way it went in as the channels are much wider. Steve.

Hi I think you will find that there is only one brake wear indicator on the front and the back repair cables are readily available on line, my Alfa Mito has two wear indicators on the front and back but only uses one station on each axle. Please note the loom cables up to the ECU are around £200 each which is what makes the repair plugs such a wonderful proposition at around a tenner. Steve.

Hi a new EGR will not cure the problem, you have to check the ASH levels and soot, but in saying that if the ash levels are high it wont regenerate anyway as ash cannot be burnt off, my guess is your EGT sensors are duff and not supplying the ECU with the correct temperature to initiate a regen therefore the DPF just blocks up, the other thing that causes this effect is the DPF pressure sensor, therefore you are better served replacing EGT and pressure sensors, BUT not before checking the DPF ash levels the ash limit is 60% anywhere near that and it needs taking off and cleaning or replacing [expensive] , in essence no amount of sensor replacement will cure high ash content. Steve.

Hi did you do the last part of the video and run the car checking the gearbox oil temp before doing the final top up I think thats probably a critical part of the service as it allows the mechatronics unit to purge air thus allowing the final top up, and are you sure your model uses 7l of oil a lot of these kits are generic and cover other gearboxes as well. Steve.

Hi sounds like the can gateway has locked everything out, the whole car is programmed to recognise any attempted theft of the vehicle or infotainment system if you fitted anything with the battery connected it probably thinks someone is trying to steal it, can your friend do a factory reset on the system, also as Cliff said the battery coding isa must do. Steve.

Hi the part number will be stamped on the original part at the back then try the breakers [junk yard]. Steve.

Hi just Google in drive shaft repairs in your area should come up with a fair list, ring round for prices. Steve.

Hi cheapest route is probably to get your existing unit rebuilt. Steve.

Hi if you get the car scanned it will probably show the faults as one time faults so get them cleared and see if they come back, the TPMS fault you can try getting all the tyres pumped to pressure then store the new value on the MMI. Steve.

Hi was the new battery coded to the car?. Steve.

Hi they will tell you its normal as I believe its something to do with the emergency brake assist software, I am like you I love that feeling when you press the pedal and its there, my Passat has a similar system but it only starts braking for you when it senses something solid about three feet from either front or rear bumper, other than that it behaves like a normal braking system, the stopping is commensurate with pedal pressure. Steve.

Hi when you put in service mode make sure you release the handbrake on the button first or it wont work. Steve.

Hi have you checked the lift pump in the tank, if you monitor its volume at idle and its around 5-600 the pump may well be on its way out. Steve.

Hi if you read some of the replies to that video you will note its a laser head lamp from a Range Rover circa 2018, this particular design was so successful they stopped making them after two years, because A the failure rate was astounding and B the replacement cost was also astounding, the LED lights on nearly all new Vag vehicles are designed with an alloy body which contains the control board which also stuffed full of silicon, so maybe that acts as a heatsink the same as the paste on chips in an ECU, Definitely no fans as I have had one apart on my Passat to repair a DRL, I was just trying to point out that for the O.Ps point of view any LED retrofit bulb with a fan unit attached was not a good idea. Steve.

Hi I think we are at crossed purpose what I need is the engine designation code, I.E. mine is CNHA that dictates where the sensor is positioned on my parts system either in the block or the thermostat housing depending on the engine type. Steve.

Hi can you tell me the engine code. Steve.

Have a look at the earlier Audis same problem, H7 bulbs give off massive amounts of heat which is why they changed to HID less than a third of the heat and brighter lights on less power, Halogen bulbs are typically used on non projector headlamps as they have a larger area for the heat to dissipate, common misconception is after market LED bulbs give less heat, WRONG! thats why they have cooling fans on the back of them, the original equipment LEDs dont have this. Steve.

Hi monitor the EGT sensors on live data if the readings dont rise quickly when revved the sensor is probably on its way out which would cause it to run lean at certain rpms. Steve.

Hi it more than likely that the glow plugs need changing, classic symptoms are it being easier to start when warm and being difficult when cold, easy test cycle the ignition on until the glow plug light goes out and repeat that at least twice if it improves the start thats your answer, no point in just leaving ignition on as the plug duty cycle expires and they just cool down again. Steve.

Hi the black adjuster moves the left to right adjustment the white adjuster does up and down the silver adjuster does the main beam left to right, leave that one alone, are your dipped beams projector lenses, can't see from the photos, if they are its most probably the reflective chrome in the bowl is burnt off at the top in which case it wont matter what bulbs you put in you wont get any light improvement. Steve.

Hi you could try a diagnostic scan and see what that throws up, if nothing try reading the live data on injectors, EGT sensors, MAF sensor, EGR valve. Steve.

Hi believe me I had this on my Audi, they have been economising on part quality since 2014 and they dont care as it adds work to the dealers. Steve.

Hi if its fitted with the rubber pad under the boot lid its quite possible the switch pads inside are corroded and have failed, you should hear the latch mechanism click when you press it. Steve.

Hi you can probably get a repair connector with wires on line Just German Parts do a fair range on eBay, is all you have to do is marry up the wires and make soldered connections with regard to the second hand ECU just get one of the many repair places to check it out before fitting. Steve.
