Chalky13 Posted March 27, 2023 Share Posted March 27, 2023 Hi all, 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’ve not been able to find the search again since. Further research says tyre pressure and several other things. I’ve had the fault codes read and it’s 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? The car drives fine but seems to have the turbo restricted as the oomph is missing I’m planning on getting the glow plugs done as they’ve 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 March 29, 2023 Author Share Posted March 29, 2023 Not making a great deal of headway in my searches, if anyone has some pointers, it’d be much appreciated . thanks 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’t. With the slightly slower cold start and no stop start working, that makes sense. Could that relate to the headlight and stabilisation lights too? I will get the battery tested ASAP, thank you ever so much for that 👍 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 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 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 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’s fluctuating between 11.98 and 12! Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 13, 2023 Author Share Posted April 13, 2023 I’ve bought a new battery and fitting that today, hopefully that will resolve some of the issues. I suspect the EGR valve also needs replacing as the car is becoming more limp ish 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? With the engine running you should get >14 v. Sounds like you need to investigate alternator issue. Kind regards, Gareth. 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 I’ve fitted the battery this morning, no difference to fault lights on, headlamp distance error, stop/start not working 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’s a huge help.

Would you say the alternator is needed, I’ve managed to track one down for stop start, as they appear rare as rockIng horse !Removed! at the moment!

Hi you need to get the battery recoded to the car, the alternator output at the plug [back probed] should be 14-14.5v. Steve. Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 13, 2023 Author Share Posted April 13, 2023 How do I code the battery? Isn’t it just a plug in and sorted ? Quote Link to comment Share on other sites More sharing options...
Chalky13 Posted April 15, 2023 Author Share Posted April 15, 2023 I’ll be taking the car to a local garage next week, seems that there’s no-one on the site here most days for advice. thanks for the advice though Quote Link to comment Share on other sites More sharing options...
