Hi try pm to Audia4KEV he may well know of an engine. Steve.

Hi think your aircon needs a degass had the same with mine and it was low refrigerant, its probably got a leak and if you look where the radiator is it might as well have a sign on it, Road Debris hit me. Steve.

Hi maybe it needs adapting again if you have VCDS there are plenty of how to do its on YouTube. Steve.

Pleeeeeeease code the new battery. Steve.

Hi I would from these figures assume the battery is well on its way anything below 85% SOC and with availability of 25AH is definitely wrong, how old is the battery? Steve.

Hi just try a gearbox reset that may well help with this, having the DPF cleaned won't affect the gearbox, normally after a gearbox service they do a reset so all the mechatronics can relearn its values. Steve.

Hi the idea of publishing the codes you have is to narrow down the components that may be causing this, you say that the vehicle was laid up for two years and you have blown two HPFPs therefore I would suggest that the high pressure side is in overrun which is eminently checkable on live data, my guess is that its the fuel pressure regulator playing about, this meters the fuel pressure within the rail and is electro mechanical therefore it can stick slightly and cause insufficient fuel to the rail causing flat spots or stick wide open and the HPFP tries to keep up with what it thinks is demand, the return system just loses what it won't use, using live data check the rail pressure at idle and then through the rev range and see if the figures add up, don't know what the rail pressures should be ideally on the DETA engine you have but I know if the lift pump in the tank is high around 600lpm you have a problem further up. Steve.

Hi the engine could well have been new or classed as such under American consumer law despite being classed as refurbished in the U.K. , the other key bits of information such as milage of the original unit would affect the value of bolting well worn parts on to a new bare unit, my suspicion is someone has used a faulty/old gasket in the system or fitted parts incorrectly, this particular poster seems very reticent to provide answers to simple questions that are simple building blocks towards diagnosis, why these people come to this forum requesting help and then abuse the person trying to help is beyond me, they expect a solution with the minimum of Information and then throw their toys out of the pram when they don't get what they want to hear, he has probably run out of sites to abuse in the states, so now its our turn, lucky us. Steve.

Hi tried to watch the video but it won't play maybe a photo would be better? Steve.

Hi I would get someone else to check if the system has any gas in it, most independent garages have a decent aircon machine and will check it by seeing if it has ay gas and then pressure checking the system for leaks chances are its either run low on gas or has a hole in the radiator either way Cliff was correct when he said they can't block, therefore I would give the ZOONS at Halfords a wide birth. Steve.

Hi the newer Audis are mostly the same, not good except for possibly Q3s that use mostly VW engines and running gear, in saying that most car manufacturers are having the same cost cutting driven problems with the exception of Toyota that consistently produce good reliable vehicles, not as plush as the Audi but why pay that money for the A4/A6 with no inherent reliability. Steve.

Hate to point this out but even if you fit a new steering angle sensor you have to recode it, if it sounds like a lot of work, its not half as much work if you don't get the wiring right as well as the coding, the electronics on these vehicles has always been complex and if you fry a body control module [any one of about five] you then have a serious problem. Steve.

Hi it always says that, thats how they make money, you could try getting your garage to open the bonnet before plugging it in, if that won't work you are going to have to go the VCDS or OBDEleven route as both these have the capability to generate the challenge code to get in, Steve.

The lock is called SFD and any car post 19 that is VAG has it, most garage scanners won't touch it except if they have a newer platform software VCDS or similar OBDEleven pro which is the cheapest option, what are they trying to repair. Steve.

Hi that would do it, the remap has possibly done the damage as the pistons on these EA111 engines have a weak point insomuch as increased boost pressure and fuelling cause the ring grooves to fail and bits fall off of the castings where the rings locate which is probably why you have compression failure, having spoken to my garage they reckon timing chain tensioners can fail anywhere between 40k-60k which probably explains why in a short time they phased this engine out and bought in an upgraded belt driven engine. Steve.
