Hi the colour will be peculiar to your model and year and some models pre 16. Steve.

Hi if you throw in the milage and any possible previous owners, service history, price?, you could well get some more serious interested parties. Steve.

Hi finally got the Hydro mounts replaced on my car as I knew one of them was out of oil by the way the car was wobbling from side to side in the morning on a cold start and also the problem of selecting first and second gear sometimes, this was because the whole engine and transmission was floating about, anyway for those who have any interest the part numbers for the Febi units I bought are as follows, left mount nearside is Febi part 3917 and the off side right hand is Febi part 43700. My two original mounts were knackered, one with no oil and the other with oil but both were beginning to show signs of splitting. Steve

Hi can you tell me what code reader / diagnostic platform you are using, also look up on google the firing order as I am pretty sure thats not the firing order as you look at the engine the plug line up is correct. Steve.

Hi was it an O.E DPF, genuine Audi, if it was aftermarket they do tend to block up more often as they are a smaller unit and have a Cordierite core instead of a Silicon Carbide core, ask the garage if they have VCDS as that will tell you how many regenerations the DPF has had since fitting, my guess is its not regenerating because the garage has not done the appropriate re adadaption of the new unit or its a wrong un, only other solution is get the DPF mapped out and gutted. Steve.

Hi most likely a corroded connector where the wiring goes on to the fixing on the window the bcm will always turn something off that is raising a current resistance. Steve.

Hi, yes you can activate other features but only if they were fitted as a dormant option when built/specced, you will also need VCDS not the cloned version as this will only let you do certain things, look on youtube as there are plenty of how to activate on most VAG vehicles. Steve.

Hi try inspecting the wiring loom to that injector especially the plug connector to the injector as these are prone to corrosion, please can you quote the DTC number. Steve.

Hi that one, tighten /loosen will be a trial and error job, my guess would be mark the current position on the nut and the body and try a full turn either way, and at least you will have a point of reference if one way will not improve your situation. Steve.

Hi it will normally be in the vent for that foot well which will involve removing the trim on that side and then squinting down the vent hole with a good torch after removing the duct cover, its a twist out unit that looks like a strip of metal with rivets in it and a plastic base with a plug connector which twists out to release it from the side of the vent. Steve.

Hi get it plugged in and diagnosed for faults, could be anything from a dodgy o2 sensor to a blocked fuel filter. Steve.

Hi I think someone is living in a parallel universe, went in to my local garage to book my car in for the engine mounts and ran smack bang into an argument between my mate and a customer who had bought in an Audi Q5 TFSI 2018 for a service at 42k she was told the bill was £350.00 and was acusing them of robbing her as the dealer had quoted £250, my mate rang the dealers who told him that was for the oil service only and a full service with filters was £750, she cleared off and phoned the dealers and then came back full of apologies and a wad of cash, I had a chuckle looking at the old air filter with the date 2018 on it the spark plugs were all burnt up with blow by around the porcelain, moral of the story ask what you actually get for £250.00, do the maths, about £40.00 for the parts and the rest is labour and VAT. Steve.

Hi it is indeed just make sure you follow the instructions on the bottle. Steve.

Hi you had a leak and the only thing you can do is run it as Gareth suggested, this is the only way you will find out which had the trapped air, the car or the mechanic. Steve.

Nope they all need air and the injector cycles are all controlled by that valve, open the butterfly to allow in more air the injector pulse for longer to match the air ratio in coming, shut the valve means less is being injected because of the lower airflow in coming. Steve.

Hi the extra 4-6 mpg is selling point with Hydra and on a run is where it really scores, back in June I did from where I live to St Ives in Cornwall , 750 miles round trip on £72.00 worth of diesel. Steve.

Hi you have just got to love the way the torque comes in, blow the expense. Steve.

Hi Keith is correct, but you can help it all by using a good quality fuel additive take a look on the Hydra fuel additives site, I do a lot of short journeys [Cab] I use the Maximus additive as I find it ups the Cetane rating enough for the car to kick off a regen as soon as I do any run over three miles. Steve.

Hi I believe it should hold pressure, they are not the strongest of set ups and it won't take a hell of a lot to jam the flaps up, I did a manifold on an old Vectra once and GM to their credit had made the flaps and drive assembly from metal but the crud had terminated it, so we cleaned it up and set them to the optimum position with a delete kit fitted, jammed open, it ran like a Swiss Watch, the flaps are only there to make the air intake charge more turbulent as the engine revs increase so when the injection cycle starts the fuel hits the cyclone of air and mixes more efficiently, in saying that some MK4/5 Titanium Sport Mondeos had them and they gave no end of grief, fortunately the one I bought was a later model and was not fitted with them and it still ran like an unmarked missile, those who knew said Ford had got bored with the warranty claims. Steve.

Hi Dale if you follow the pipe for the EGR the throttle body will be just below where the pipe goes into the manifold, the throttle body has a wiring connector on it, just be careful when cleaning as the drive gears are plastic and the teeth are easily damaged they do an upgraded refurb kit for them so it might be worth looking in the control/gearbox to see what yours are like. Steve.

Hi thats why I suggested you get the number off of your old part, the petrol version will have the same plug but the wires may be a different con figuration to the diesel and still use six pins, they should be able to match the part from your registration/VIN but another thought has occurred to me is the throttle body clogged up with carbon as that would cause a code for the TPS my daughters car showed the same code but on closer inspection it turned out to be the throttle body as it was covered inside with carbon and was having trouble moving the butterfly so I changed it did a readapting of the new valve scrubbed the code and its all good. Steve.

Hi sorry it did not work, swirl flaps are as bad as EGR valves for going wrong the actuator is on the inlet manifold and I know because its all plastic they wear or break, I have seen videos about repair/ delete kits, only one other question is did you look at doing an adaptation on the new valve with the vids. Steve.

Hi if you have the same problem a small piece of advice is that if you re time the cams and it works you have probably gotten lucky, what normally happens is when the cam timing moves the valves hit the pistons so something has to give, normally the lobes on the cam spin as they are sweated on to a tube at the factory so worse ways you might be in for a couple of new cams and a belt kit. Steve.

Hi the TPS sensor is attached to the pedal, a bit fiddly to remove but once off go buy another with the same part number as your old unit, diesel TPS are different from petrol as the wiring connector is the same but the wires are pinned in a different sequence. Steve.

Hi buy a plastic trim remover kit for eBay, gently prise the unit out and then change the bulb, I think the bulb is a 501 bayonet type but you can either read the writing on the bulb or visit your local spares shop and let them match it up. Steve.
