W8CMP Posted August 31, 2017 Share Posted August 31, 2017 Just driving home this evening in my June-registered A6 Avant, and the MIL came on. Tried phoning my local dealer to take it in for a scan to be told the earliest they can do is 10th October !!! I just want them to scan it while I wait, but they don't do this ! Now I'm home my VAG-COM scan shows the following: 1 Fault Found: 8806 - Cylinder 3 Internal Pressure Sensor P13D6 00 [172] - Implausible Signal MIL ON - Intermittent - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 1 Mileage: 5190 km Date: 2017.08.31 Time: 07:29:01 Engine speed: 1875.00 /min Normed load value: 73.7 % Vehicle speed: 24 km/h Coolant temperature: 91 °C Intake air temperature: 67 °C Ambient air pressure: 1010 mbar Voltage terminal 30: 12.740 V Unlearning counter according OBD: 40 Cylinder head: pressure sensor 3 bank 1: raw value: 0.211 bar Cyl. head: press. sens. 3 bank 1: max press. in decelerat.mode: 0.68 ° Cylinder_pressure_offset_cylinder_3: -2.813 bar Cyl. head: press. sen 3 bank 1: error stat. combust. rm. press.-Bit 0: 4 Cylinder head: press. sensor 3 bank 1: grp. run time: -2.5 µs Readiness: 1 1 0 0 0 I now have Audi Assist (AA) coming to look at it...we shall see what they can do.

Steve Q Posted August 31, 2017 Share Posted August 31, 2017 Welcome to the forum Chris :) youll find the members on here are a friendly and helpful bunch :) sorry to hear your having issues abd sorry Audi can't fit you in till the 10th of October. However this seems to be a common occurrence with Audi and they are often overbooked! Keep us posted on how you get on with Audi Assist and hopefully the issue is resolved soon abd thankfully it's still in the warranty period. Youve not had the emissions recall carried out by any chance? Cheers steve Quote Link to comment Share on other sites More sharing options...
W8CMP Posted August 31, 2017 Author Share Posted August 31, 2017 Hi Steve, Audi assist is now coming to my work tomorrow to try to solve the problem. Crossing my fingers as I really don't want to lose my car for any length of time. I'm hoping my car won't need an emissions recall as I only bought it brand new in June. I'll keep you posted once Audi have looked at the car. Cheers Chris Quote Link to comment Share on other sites More sharing options...

W8CMP Posted September 1, 2017 Author Share Posted September 1, 2017 The technician visited me today - great guy - very helpful. His diagnosis confirmed mine, and it requires a new glowplug / sensor. Problem is my car is very new, and Audi has upgraded this part recently, so they didn't have one available today. However they've confirmed it will be coming in over the weekend and he will re-visit me to fit it on Monday. In the meantime he has cleared the MIL & confirmed the car is fine to drive as it was only an intermittent problem. Had lots of discussion about the car (and my previous Phaeton & Passat W8) and he advised a couple of things. First was to top up the Adblue every 3,000 miles or so. He said there had been issues when the tank runs low, so best keep it above half if possible. Also said my experience of Audi service dealers being booked up for months ahead is fairly typical now, so book well ahead of time. He's not aware of any particular issues with using cheap supermarket fuel, but a tank of the good stuff every few months can only be good for it. Our octane rating here in the U.K. is the lowest in Europe. German cars are designed for better fuel - equivalent to our 'Premium' in octane. There are lobbies to get the government to legislate a minimum octane rating from suppliers (i.e it has to be at this level or above) to enable engines to run more efficiently and cut down emissions. He told me the battery is under the spare wheel in the boot as I didn't know where it was. Also told me of issues with stones getting between the brake calliper / disc high has required a slight redesign of the components. This is a common problem for him to deal with. Just be careful when driving over gravel or loose surfaces - especially the loose chippings from local authority road resurfacing. I feel much better today about my car, and look forward to the new glow plug being fitted on Monday so I can get back to normal trouble free motoring.
