Chalky13 Posted March 27, 2023 Share Posted March 27, 2023 Hi all,聽 Our A1 threw up some fault lights last week, with the headlight distance adjustment error and stability control lights coming on. Within seconds the glow plug light started flashing and then the EML came on. I did an initial online search and it seemed to be a sensor on the lower arm maybe that caused the lights and stability issue. I鈥檝e not been able to find the search again since. Further research says tyre pressure and several other things. I鈥檝e had the fault codes read and it鈥檚 come up with these P0641 P064100 P15A000 P181C00 U100800 U111100 U111300 Would anyone have a suggestion before I end up throwing money at this I could do with not spending?聽 The car drives fine but seems to have the turbo restricted as the oomph is missing I鈥檓 planning on getting the glow plugs done as they鈥檝e pinged the lights on before anyway potentially, and when starting the car it takes an extra few seconds to start to what it did when we got it a year or so ago Quote Link to comment Share on other sites More sharing options...

Chalky13 Posted April 3, 2023 Author Share Posted April 3, 2023 Hi Steve, I haven鈥檛. With the slightly slower cold start and no stop start working, that makes sense.聽 Could that relate to the headlight and stabilisation lights too? I will get the battery tested ASAP, thank you ever so much for that 馃憤 Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 7, 2023 Author Share Posted April 7, 2023 Hi Steve. Still not got to the garage due to work commitments and closed today. Ive plugged my VD500 in again and this code popped up, P0401 which suggest EGR valve. I presume that would trigger the glow plug light and EML, plus make the car restricted as there is no turbo now. From speaking to other diesel users at work, seems to be the issue of the moment as several have their EGR valves down too. Is there maintenance to do, IE long runs or giving it a blast, or is it just something that needs changing? thanks again, in advance聽 Quote Link to comment Share on other sites More sharing options...
Steve Q Posted April 7, 2023 Share Posted April 7, 2023 Yep egr would throw up a eml light. You can try to get the egr cleaned. However the best option is to replace it with a genuine one. Cheap aftermarket ones can be of questionable quality聽 1 Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 10, 2023 Author Share Posted April 10, 2023 Hi Steve, the reading for the battery is 12.61 volts聽 Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 10, 2023 Author Share Posted April 10, 2023 And checked it when running, it鈥檚 fluctuating between 11.98 and 12!聽 Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 13, 2023 Author Share Posted April 13, 2023 I鈥檝e bought a new battery and fitting that today, hopefully that will resolve some of the issues. 聽 I suspect the EGR valve also needs replacing as the car is becoming more limp ish聽 Quote Link to comment Share on other sites More sharing options...
Magnet Posted April 13, 2023 Share Posted April 13, 2023 What did you check the battery with Dave?聽 With the engine running you should get >14 v. Sounds like you need to investigate alternator issue.聽 Kind regards, Gareth.聽 Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 13, 2023 Author Share Posted April 13, 2023 I checked it with a car battery checker, clipped on both聽 I鈥檝e fitted the battery this morning, no difference to fault lights on, headlamp distance error, stop/start not working聽and stabilisation error, plus flashing glow plus. The tester can check the alternator, just need to find it and how to do that I guess. thanks Gareth, appreciate the pointer, that鈥檚 a huge help.聽 Quote Link to comment Share on other sites More sharing options...

Would you say the alternator is needed, I鈥檝e managed to track one down for stop start, as they appear rare as rockIng horse !Removed! at the moment!聽 Quote Link to comment Share on other sites More sharing options...
