Hi have you had the battery checked as some of those codes are low voltage. Steve.

Hi I don't think you have read the first post properly at no point did the author mention 4000 miles, come to that no other person involved in any reply mentioned that figure either, I think the original post mentioned 7-10k which I would personally take in view of the fact same as me does a fair amount of driving over a month, if you only use the vehicle over short distances on mostly good roads you will probably achieve higher milage, driving style will always impact tyre wear but if you read the post he states he is getting 25k out of the tyres on a discovery which would indicate he is not using rubbish rubber or driving like a lunatic, the other fact is Q7s have a well documented reputation for tyre wear, they can't all be lying. Steve.

Hi if the washer got between the belt and the crankshaft gear the washer has probably moved the belt timing only way to check is strip it down and re time it, if it still won't turn [by hand ] then something is bent its no good trying to turn the engine over without it being timed up as there will always be a loss of synchronisation between the two elements camshaft/crankshaft so that means an open valve. Steve.

Hi any garage should be able to check the compression electronically, chains can last anything from 60k to 200k dependent on oil service and oil grade used and they won't rattle on start up way before that you will develop what seems a misfire which is the crank/camshaft synchronisation going to pot, the chain guides are made of nylon and are prone to wear or breaking up, thats why I suggested getting a diagnostic scan as if there are any faults to do with the timing, walk away, there are a few of them on here that have had cam chain problems with much lower milage, at the end of the day the whole car has done in excess of a 100k and everything is tired suspension, engine, gearbox and speaking from experience with my car at 150k I am experiencing suspension bush failure and that is not cheap, given the age of the vehicle and the milage unless you intend to do a lot of the work yourself I would be inclined to get something else with less miles, its cheap for a reason. Steve.

Hi treble smoke is very possibly is either valve stem seals or a sticky compression ring, turbo seals I doubt but an easy check is remove the intake for the turbo and manually pull the vane boss up and down and check back unforward for end float should be about 1mm up and down with no end float from side to side, I would also be checking for scanned faults and any history of cam chain replacement as at that milage all four chains are well on their way, if its dirt cheap buy it and run it until it dies, turbo recon about £600 for the part and a cam chain change anywhere over £3000. Steve.

Hi yes the dash lights will still work the only other thing I can think of would be the pick up on the ignition switch, start from the beginning, did the car crank ok before you changed the battery and who changed it, you stated that you replaced the switch was it new or second hand, the switches should have a transducer ring near the barrel or around it these are very prone to voltage spikes. Steve.

Hi wherever you take it to get the work done will probably remove the filler flap and send it to the paint mixer and they will scan it and mix the paint to that, mine is a grey pearlescent and apparently the guy who did the work said there are about five shades of that paint code so he removed the flap and gave it to the paint supplier and bingo perfect match. Steve.

Hi if you have a wheel specialist in your area they will be able to advise you on the spacers as they will have the information as to what size spacer will bring the offset back to factory on the new wheels. Steve.

Hi no lack of coding will only knacker your new battery in record time but won't prevent the cranking, a lot of the codes are very old according to the dates on the faults I can only suggest that you clear them at some point, the only code of interest is P2015 as if the throttle valve is not reaching its start position that would prevent it starting but not cranking, what diagnostic platform are you using, due to the lack of any relevant codes for cranking failure it could be an immobiliser problem, I think this might be a auto electrician job as they will be able to test continuity of voltage between the key and starter and the immobiliser function. Steve.

Hi just because it has not got stop start it will need to be coded as the stop start has nothing to do with this, but the battery energy monitor does and thats what controls the charging from the alternator, with regard to the clutch position sensor I am not sure what type you have if its on the pedal its clearly visible and will be sitting just above the pedal so when you press the clutch down you will see the little pin in the unit start to drop down, if the sensor is on the clutch master cylinder you have to change the whole unit, easiest thing to do is get the vehicle scanned for faults as I am sure that will tell you straight away as at the moment it could be a starter, crank sensor, clutch switch, sorry I can't be of more help. Steve.

Hi most Ford timing belts are a dream to do, [except for the new Transit] where you have to do the wet belt if you have any sense, the guy I use has the universal cam pin kit for Audi but still had to use drill bits to lock out some of the gears as the kit didn't have the right pin for my engine, I swear they do this on purpose to stop people having a go themselves, the pin and locking kit I bought for my 2.0 MK4 Mondeo worked on the 2.0lt and both my 2.2lt models, I think you have to go for TDC and find bits to fit the holes, most of the engines are the same but are given different designations to confuse everybody, DETA,CNHA, CDUD. Steve.

Hi either way you have a timing chain problem and no amount of who said what under debate will actually cure what you have which is a cam timing anomaly which is caused by premature or otherwise chain wear, with regard to your specimen symbiotic case its a moot point as no one knows if the garage who did the chains also made the camshaft finite adjustments to the vernier gears on the camshaft sprockets. Steve.

Hi, it is an engine out job as there are four chains with associated guides the chain system when viewed is like a maze and good long days work, cost wise I would be guessing, so have good shop around. Steve.

P.S the last code you published on the first post is the Pcode for the same thing, cam timing out. Steve.

Hi I quote, that guy had also[ just had the chain and tensioners replaced], anyone reading that statement would assume he had done the same as you have and has the same problem, the devil is is the detail, I would think one or more of the chains is slack which is whats throwing up your code with regard to milage cam chain wear is a law unto itself its very reliant on oil changes/oil quality, ask any mechanic about cam chain life and they will tell you how long is a piece of string, no one knows exactly as there are to many contributing factors. Steve.

Hi which of the four cam chains did you have replaced or all of them as if it was just the main chain only that would throw the camshaft timing out as the other chains are stretched to death as well, if it was all of the chains changed then someone got the timing slightly out. Steve.

Hi ring Audi and give them the VIN on the log book as yours could be either as that was a change over year 2011-2018. Steve.

Hi I don't know what milage your car has on it but if you start fiddling with a car of that age now its like trying to get your granny to run up hill with a sixty kilo ruck sack, to much extra stress, there is no such thing as a cheap power gain and as for the YouTube brigade they just tell you what they think you want to hear, like the guy that did a video on a de coke using water and a spray bottle, yes it probably works but where do all the loose bits of carbon end up?. Steve.

Hi George, there is a new type of VCDS adapter available on the net I am chasing one at the moment, OBD 11 is good but you might need to buy the pro version, another thought occurs to me, you say you cleaned the throttle body, how old is it as I have cleaned oider cars bodies before and had them do the same thing thus necessitating a new body, I understand your problem as my garage did a lot of work on a John Cooper special edition a couple of years ago which is now out in Spain and the steering racks gone so the customer wants to fly a couple of their mechanics out with a new rack and fit it, the guy is at his wits end with the local garages. Steve.

Hi is your VCDS unlimited VIN platform, may well be that you have to get into the ECU to correct this which means dealer only. Steve.

Hi you won't get through as out of hundreds of phone lines only twenty are ever manned, the excuse is the others are all isolating, might be best served advertising it as a barn find and denying any prior knowledge. Steve.

Hi you can go as far as you want but the end result is always the same, DEAD ENGINE, the Bi Turbo system is designed thus, the low pressure turbo increases the velocity of the air going into the high pressure unit which negates what is known as LAG, the crankcase is strengthened when built to take into account the fact it flexes when the main turbine kicks in and the boost bar settings are all calibrated to stop over boost, 600bhp just by changing the turbo and nothing else ? also did anybody mention how long it lasted, back in the early eighties anyone who had a Metro turbo was winding the boost control module up to eight bar instead of four yes it goes like stink, but little while later they were all moaning about the rods being outside the crankcase and not in it. Steve.

Hi if its not SORN they will eventually catch up normally when the new owner taxes it which alerts them to the fact the previous owner had neither SORN or VED and then they come looking, the Bar Stewards have a total non excuse policy and will try to fine you or claim back tax, my neighbour sold his SORNed Focus and got a fine for not informing them despite sending off the logbook, they want you to do all the work instead of them having to do it, I don't know what they do in Swansea but it is not a lot except find ways of bullying people for money. Steve.

Hi you should be fine fitting LEDs as long as the bulb base is the same and they are Canbus error free versions. Steve.

Hi unfortunately there is probably none left originals anyway so you will be better served having a measure up and sourcing that type of seal from a retro or aftermarket seal company, I did it with my daughters Alfa a couple of years ago and what I bought was an aftermarket seal that was a couple of mm bigger on the sealing bubble but at £16.00 for three metres it was a no brainer, if you could post a couple of pics of what you are replacing that might engender more ideas. Steve.
