Hi if the cam timing was out I would expect the engine to run badly, if your friend has checked everything to do with the belt and chain you can only re check the cam adjuster but a tooth out would be very noticeable thats why I am thinking sensor as if its original they can become blind and submit the wrong data.

Hi if you have done the rest of it I would strongly suspect the cam position sensor is throwing a wobbly

Hi take the rear light units out and check for power to the brake light bulb, with the aid of an assistant to press the pedal, no power will probably mean the switch on the pedal is faulty.

Hi they fail because the water for the washer flows back down the spindle and through the rubber grommet in the window, took me a while to work that out, so when you replace the motor also replace the grommet with a liberal coating of silicone grease, grommet is about £16.00 on Ebay, had three motors on mine but the last one was still good when the car went so the grommets definitely a winner.

PS the only electrical bit on the main pump is the baffle the rest is cam belt driven.

Hi as you look at the engine from the front its under the timing cover on the right hand side, you should see a wire coming out at the top of the r/h side thats the electrical connector for the pump baffle this operates by covering the impeller blades so that the engine warms up quicker, once up to temp the shield moves back and allows full flow via the impeller, the pump on the right of the engine is auxiliary and only comes into play when the engine is stopped in extremely high temps and continues to pump coolant round to stop the cylinder head from cracking.

Hi they are tamper proof screws they are normally drilled out but a word to the wise only touch anything in there while wearing latex gloves as the sweat on your fingers will kill things. Steve.

Hi get a swirl flap delete kit, loads on the internet. Steve.

Hi in three days anything up to 1 volt would be acceptable furthermore I can't find any logic in the statement that changing the timing belt would have any effect on the Adblue system as they couldn't be further away from each other, same as the earth from the moon, all dealers are the same but Audi taught the rest of the trade when it comes to being inventive when getting work in, the only parasitic drain with that lot will be on your wallet, now you have a new battery see how it goes, your mechanic sounds like a good guy. Steve.

Hi did you have this battery coded, if not the BEM will continue to charge at the same rate as the old battery which in record time will cook the new battery and kill it stone dead, seen a few like this in my time and its hard to convince people of the importance of battery coding, half an amp is not an unusual amount and if the battery is in good condition its sustainable, the batteries are massive, damage wise 10-11 volts will kill it. the Adblue control unit is b@ll@cks they either work or they don't as for powering down the whole car never does this as there are alarms, central locking. infotainment all in a low power sleep mode until you hit the unlocking button.

Hi the power spike is always there thats how the car checks its own electrics for things like diodes that have been fitted to airbag connections to shut the airbag light, myself I would be looking at the battery, what brand and has it been coded to the car properly, these vehicles are very twitchy about the kind of battery used and as an example my A6 had a new Yuasa battery just before the lockdown and sat for the first three weeks before I drove it anywhere. Steve.

Hi they are not that difficult if you observe the following you will need a deep socket and a low poundage/NM torque wrench and a can of plus gas, get the engine nice and hot and using the torque wrench set at no more than 30nm undo the plug if it wont move at that setting apply a liberal dose of plus gas and leave to soak for twenty mins, go on to the next plug with luck they will all give a little click and come loose [Do not force the plugs] as if you snap one they have to be removed by a professional removal tool, mucho deniro, when replacing coat the threads in a smear of Aluminium paste making sure not to get any on the heating element, when tightening the new plugs don't go more than 28nm. Steve.

Hi the heater matrix is possibly blocked or the thermostat is faulty [temp sensor] on the thermostat, I would be taking it back, I hope you didn't pay for all the other parts. Steve.

Hi Cliff its not a LI-ION battery LION is the brand and believe me they aint any good. Steve.

Hi what I was trying to point out is your car is petrol and is not fitted with glow plugs, you can't have a valid fault code for that which doesn't exist therefore it suggests its come from a generic scanner which I have often found to be the case, whereas manufacturer specific readers are often far more accurate. Steve.

Hi yes spend your money on an OBD Eleven reader then you can look at what you want whenever you want on your phone and not become a victim of overcharging garages, you will be able to tell them what the problem is. Steve.

Hi not quite getting this, you mention glow plugs and in the next breath its coil packs? if its petrol it wont have glow plugs thats probably a random code thrown up on your diagnostics. Steve.

Right Quit panicking and read through the posters answers, as Rybrook pointed out you need a code reader to put the battery back into sync with the car OBD Eleven is a good choice its reasonable and does the job, you don't need a code as you can use the old one that appears on the scanner just change the last three digits when it accepts it a slide bar comes up that says write slide to the right and it informs the new battery to the ECU, why you bought a Lion battery is beyond me, they are absolute non cheap garbage you can have so much more for a few quid extra, in my lifetime I have had so many problems with this brand I avoid them like covid. Steve.

Hi its either the temperature sensor that controls the fan or most likely the fan control unit mounted on the fan assembly in front of the radiator. Steve.

Hi if as Gareth said you invest in a trim removal kit the job is fairly straight forward start at the top and work your way round down the right side, the cover has a push in locking system at the bottom so once the top and sides are free lift the cover up and out, depending on the model some of the covers are glued to the rear lumbar adjustment this can be removed from the metal plate with a bit of persistence and re attached with velcro, heat the plastic with a heat gun but you have to keep the the heat moving whilst pushing gently from the inside with the plastic handle of a screwdriver or similar, did a lot of this with bumpers during the eighties they took a bit of time as they were a lot thicker but the fact is ABS plastic will always try and go back to its moulded shape. PS any clips you need to replace are on Ebay at a tenth of the price from the dealer. Steve.

Hi its all dependent on the type of engine you have, there is a setting on VCDS but I can't pin it down because I don't have your car to plug in to, therefore can you supply the information to narrow it down, also check the vacuum pipe to the unit as this can be the original problem as any loss in the air circuit will cause problems. Steve.

Hi OBD eleven pro, if you go for the VCDS as I did its expensive and wont read anything past 2019 because of the SFD firewall system on the later cars, therefore I had to buy OBD eleven as I now own a 21 plate passat with the SFD but I tried it out on a few cars including my accountants 2017 Q5 and it read everything, look on their site and choose what suits you. Steve.

Hi to be honest you can't tell what a batteries condition is with a multimeter, best go to Halfords and get it tested under load I.E, everything switched on lights, blower, heated screens, if the battery is remotely the original its knackered, you say the ABS pump was recoded with what?, was it your unit repaired or a new unit. Steve.

Hi should be able to do it in basic settings, but I will look at my VCDS Monday and try and work this out for you but in saying this I have not heard many glowing reports of aftermarket manifolds. Steve.

Hi pretty straight forward if you look at the second picture the tab in front of you has no locking hook, that is the position tab which is lower and wider than the rest so if you find the reciprocal slot on the vent once located it should just push in. Steve.
