Hi,

Can you help please. I have a DRL problem with my Skoda Yeti 2016 L&K 2.0tdi 150hp 4x4.

The lights Mil is illuminated and the BCM is showing faults as in the scan. Sometimes it will show the fault with just the DRLs and sometimes the same fault with rear lights and or brake lights as well.

The rear and brake lights are working as they should. The DRLs work as sidelights and come on with the headlights when switched manually. When switched to AUTO, the Xenons work as they should with daylights sensing on/off, however, no lights are on at the front in good daylight. The DRLs do not come on in the OFF position with the ignition on.

The original problem I had with the car was that in good daylight, both the DRLs and Xenons would be on when switched to AUTO. Everything else, including DRLs were working fine with no DTCs shown. It could well be that that I altered something but I have put all the codes and adaptions back as per the original fault free scans.

If I clear the DTCs, the next scan comes up free of faults until I switch the lights on, in any combination and then the error code returns. If I code the DRLs off, the DTC and Mil disappear but then, I lose the LED sidelights too.

This is driving me bonkers as I have spent days on it. Hope you can help.

A quick look at this, nothing stands out as a single point of failure beyond the J519 itself..... :confused: I'm not saying you have a J519 at this time.

Verify fuses for J519 are to factory design, and that they the sockets for those fuses have a good bite on the legs of said fuses. On the J519, unplug and verify good clean electrical contacts. The bulbs in question are on T52a and T52c of the J519.

@Trilux: Hi. I'm not familiar with MY16 Yeti (I've never really understood PQ35 platform cars) and certainly try @Jef suggestion first. However, in reading your post, I note that the DRLs are operational in some modes and (if I understand your post above correctly) I also note that there has been some coding intervention in the past directly related to the DRLs.

Now, while I acknowledge your belief that the changes have been reverted to their original settings, and without intending any offense in my suggestion - perhaps there may be value in confirming your belief. Again without meaning to be rude, it just may be possible that the cause for the fault could be a missed channel setting, or a wrongly chosen value - I'm just hypothesizing.

You may not be aware that VCDS keeps a record of ALL the changes that you make including the old and new values. So, if @Jef suggested checks proves OK -on the laptop that you use to run VCDS, go to the the directory C:\Ross-Tech\VCDS\Debug and open the files AdpLog.CSV and CodingLog.CSV with a reader like MS Notepad, or MS Excel. Confirm that each of the DRL related changes have indeed been correctly reverted to their original values.

Hi Don, thanks for your message. I‘m always appreciative for any suggestions and would in no way be offended.

I have now done as Jef suggested and sadly that has made no difference. As I mentioned in my post, I did reset all the codes and adaptions to the original but should have mentioned that this was done with reference to the AdpLog and CodingLog files. I should also have mentioned that the car is completely standard and unmodified.

Jim
