Hi, wonder if anyone can shed some light on this as my local dealer is not sure and doesn't want to start taking apart the dashboard unnecessarily. I've noticed in the winter months on longer journeys when the engine is up at higher temperature the climate controlled heating just gives up blowing and I start to feel a draft, etc.. In the summer months the same applies to cooling and the blower just stops delivering the cold air to keep the cabin at setpoint. When it does this I generally note that cold air is still delivered to the rear passenger vent in the back of the armrest but nothing from the front vents. Putting on AC max results in a lot of noise from inside the dash over to the left around the glove compartment. However, turning off AC immediately starts to release more air through the front vents and then, after a few minutes of restored air, turning the AC back on starts to chill the air again, though not as chilled as when starting the car from fresh. Is this the AC compressor at fault, blower motor, blend valve(s) or perhaps even some sensors somewhere? The only fault code the dealer has managed to extract from the ECU related to icing up on the AC compressor? I have had the refrigerant recharged recently which the AC service agent said wasn't significantly low on gas.

It needs to be done using a decent code reader & diagnostic machine. If you don't have access to one, most garages and battery suppliers will be able to do it for you.

Yeah I will just change everything, from what I can see it look like it might be coming from the plastic flange bit that connects to the egr cooler, I think there is another plastic piece behind that aswell (back towards the inside of the car ) but not sure what that's called

Hi its obviously in its early stages, the reason it is slipping in higher gears is because of the torque load in higher gears, it used to be the old way of testing the clutch, find a nice hill and change up to early floor the throttle and if the clutch was good the engine would labour, if not it revved up, I would get it checked ASAP as when the clutch slips it creates a phenomenal increase in gearbox temps and cooks the rear crank seal which is a whole different story, having had it happen to me I can say its not a good day out. Steve.

Don. If you can smell the coolant it must be escaping somewhere, though at a mere 1500 miles per year the loss may be so small that you don't get a warning before the garage tops it up during annual servicing.

Thanks for the information which suggests that the old caliper was indeed at fault, even if nothing was visibly wrong with it.

That makes sense, and fits Audi's push for subscription services.

Hi yes but the new module would have to be coded to the car, try and find a local car audio specialist who will be able to offer a hybrid solution rather than get in to major removal of the existing unit. Steve.

Hi sounds like the Haldex unit in the rear diff is on its way out this would put the car in to limp as its controlled electronically by a module. Steve.

An impossible question to answer because you have not revealed the brand in question.

Thanks Scott. That's useful information.

Welcome Don, My first port of call would be to return the car to whoever carried out the front end bodywork. If both horns were working prior to this then it’s reasonable for you to expect them both to work now - unless one was damaged - at which point it should have been renewed. Believed each to be behind the spotlights (if fitted) or the plastic grilles if not. Regards, Gareth.

Happy to share further photos if required.

The vendor has not returned to the forum for three years so it may pay you to direct message him.

Thanks. Mine has heated seats but not the wheel.

If it’s an S7 TDI it will be an 8 speed Tiptronic box. These can easily handle the torque. I check it’s in dynamic mode, etc. ZF-8 boxes have a service kit, so I’d be inclined to do that first before you go anywhere near a remap. Audi will tell you it’s sealed for life, but do it 60-80k miles. I follow a few companies, so Decimal Tenths are Newcastle based, or Darkside Developments in Barnsley. Probably the only companies I’d entrust the work too. They are both VAG specialists. For the Tiptronic service, then Mackie Transmissions, Glasgow.

Hi no you have to change the whole unit.

In general, hybrids will try to maintain a high state of charge so that electric reserve power is always available, however many other factors can influence when or if the electric motor will run. Perhaps yours is behaving normally, and you had not previously met the conditions for petrol to override electric.

Welcome Nick, If we can help we will. Regards, Gareth.

Clifford Thanks yeah this the problem I am having I have had a look and I have to say unless it's a quattro they don't seem to be worth a lot not that I am sure I would be selling it but also getting body parts is proving really difficult but it seems a shame to break it for parts.thanks for your feedback.

Hi just thought i would let everyone know and stop all the confusion on the virtual cockpit with headlights in Europe. just been to 9 countries on a road trip and never got flashed for my headlights. left them on auto and turned off high beam assist . started the car in France and the headlights automatically adjusted themselves gong by the gps. switched over from mph to kmh in mmi. enjoyed our first long journey in the A4 of approx. 1900kmh. it took me ages to get response from Audi about headlights and found out from my neighbour who works for VW. happy travels.

Hi Dan, thinking off the top of my head, could there be a leak perhaps, but assume that would have been checked when you went for a re-gas? Another option potentially is the a/c condenser if it's not blowing cold. I'm sure other members will chip in with thoughts/comments but good luck and hope you get it fixed, especially for driving about in the current heatwave! Nick.

Yeah see when I brought it the guy was giving it beans and nothing was untoward so that’s why it’s very puzzling, thanks for replying am due to get car scanned in the next couple of days so will give an update then

The trim pieces have been kept in case anyone needs the set, I have the 4 door pieces too and apart from a few clips they are in good condition. Once its running again, it will be off to get a roll cage made, as there's nothing available to buy.

It was the internal filter not supplied, got one on Amazon for a fiver. Even came in an Audi package as OEM part.
