I had to take off the tailgate trim to do the wiring. Everything looked Ok; there was no staining or indication of water ingress. As I mentioned the spring clip on the corroded bulb holder was missing and the paintwork around the bulb holder also showed corrosion so possibly the water had got in between the bulb holder and the tailgate. The other bulb holder was fine.

Hi, I have now replaced the number plate bulb (Pt.No.K1K9943021D £18.90 inc vat from Skoda) Also needed to replace the connector on the end of the wiring loom. I got a connector from Skoda (Pt.No.K8w0971832 £5.64 inc VAT). Unfortunately this was only the connector casing ie no pins! Pins on wire tails are available from Skoda. But I searched on 8W0972575 (the male connector Pt.No.) and I found that I could get the male connector and mating female connector with wire tails from Total Auto Connectors (PA Products) for £7.98 inc Vat with next day delivery. So I cut off the existing male connector and spliced in the new male connector. Also I bought some Permatex Dielectric Grease which I put on the electric connections. Hopefully this will last for a while.

Hi, This problem happened to me 6 months ago and about 8000 miles ago. Since then I have had no problems at all with the injectors. I checked the resistance of each injector and all were in spec. So I am assuming it was an intermittent electrical fault.

I don't think there is water ingress other than between the bulb holder and car body but I plan to take off the tail gate trim to check. I will try to get some 770 grease or similar.

The photo below shows water damaged bulb holder.

Yes, I am planning to coat the male and female part of the connector with vaseline. Unless there's something better? Also it looked very likely water was leaking in between the bulb holder and the car body possibly caused by the missing spring clip. Considering using sealant between these surfaces to ensure it is water tight?

Hi, many thanks for the reply. I have ordered a new bulb holder and connector from Skoda. Pick them up on Saturday. I am not sure exactly what the connector will consist of but it seems to be a spare that is often supplied with the bulb holder. I will keep you posted.

Hi, On a 2015 Fabia 1.4TDI Hatch one of the number plate bulb holders (RHS) is badly corroded and the body work that the holder fits into is rusting with the paint blistering. The other bulb holder and body work (LHS) are fine. Also the bulb holder was so badly corroded that in removing the electrical connector the metal parts of the holder broke leaving part of the bulb holder contact pins in the connector. See below. Has anyone had a similar problem? The bulb holders is held in by a spring clip which had disappeared on the corroded side so I think the seal between the holder and the body was not very good so letting water in. I now have to remove a contact pin from the connector. I managed to get one broken pin out with a pliers but the other is flush with the surface and I couldn't pull it out with the pliers. So any thoughts on how I might be able to remove it or could I just push it further in? Also are replacement electrical connectors available? I welcome any thoughts or suggestions.

Hi I had a similar problem with my daughters car. I found a good guide to allow me to fix it. Search "Wipers wont turn off" as one of my posts.

The outside temperature gauge has been reading OK.

HI, We had a good look at all of the pins and they did look OK including pin 32.

Hi, I got the cluster out and all the solder joints looked OK. But I got my son to resolder No.15 pin but unfortunately this made no difference. I remember reading that this problem can be caused by a bad earth to the fuel level sensor. And the fix I believe is to link the sensor earth to the earth of the fuel pump. I will investigate this. The image below shows the pins after pin 15 has been re-soldered.

The fuel gauge pin is apparently No. 15 and in this video the guy just lifted/bent the bezel out of the way. Surprisingly getting to the internals of the cluster looks quite easy compared with most dashboard related jobs.

Hi Breezy_Pete, Many thanks for replying. I have done some more searching and your suggestion re dry soldered joints looks very likely. I found the following video which covers cluster removal and repair. My son is a dab hand at soldering so hopefully he can help me out. So again, many thanks.

Hi, Unfortunately it is not fixed. I think there is a wiring issue. When I fitted the new sensor it seemed to work OK for short while and then again was erratic. I fitted a replacement pump and sender unit and have the same problem so thats why I think there is a wiring issue.
