Whilst they can make more money from motorists who use older the cars the longer it'll be around for.

I think a regular Audi problem is the motor corrodes due to water getting in the motor.

That's interesting does that mean yours is a jap import?

I'm the same, still old school. Would like Bluetooth though.

By the way I think 4B1941531C Is the part number. Yours won't have the light adjustment due to the RS6 having self leveling suspension and xenon headlights. Furthermore the older switch version, are a different finish which generally lasts longer.

Definitely done a good job and it's freshened up the interior 🙂

Think there are additives on the market you can add when filling with E10 but really we shouldn't have to do this. It's the government shafting us again.

I think the ones in the first pic look best in my opinion 🙂 I admit choosing wheels is tough! I quite like the VW take 5 wheels.

You're welcome 🙂 The surround should fit as the hole is the same size. I guess it depends on the amount of pins on the connector. The switch itself can be replaced with ones fitted to other vag cars as the switch diameter is the same even with newer vag cars. I appreciate that doesn't help regarding the surround.

Can't say I've seen that before. I'm wondering is it some wiring for a rear mounted dash cam? Who was the previous owner? Was it a business that required it to have additional lights etc if you see what I mean. Can the dealer not trave the wiring?

The headlight switch is a common item to fail or catch fire on the A6 c5. Here's a guide on how to change it by pelican parts. Part number: 4B1941531C Also certain A6 c5 won't have the light adjustment such as the RS6 due to the RS6 having self leveling suspension and xenon headlights. Furthermore the older (pre facelift version, don't have the soft touch finish which generally lasts longer. The last picture shows the difference. Left facelift with soft touch plastic. Right prefacelift cars without soft touch plastic. in addition the height adjuster can fail often due to the plastic link bar breaking. Think it connects to the ARB. If it's in tact, then it's worth checking the levelling motors. They're about 20 quid new. 1. Turn the headlight switch to the off position and push the knob inward (green arrow). Turn the knob clockwise. As you turn it, the switch housing will eject itself from the dashboard. 2. Pull the switch out of the dashboard as shown here. You need to be able to access the electrical connection on the back side. 3. Press the tabs on the rear of the electrical connector (green arrows) and pull the connector off. The new switch is installed in the reverse order of removal. https://www.pelicanparts.com/techarticles/Audi_A6_C5/16-ELEC-Headlight_Switch_Replacement/16-ELEC-Headlight_Switch_Replacement.htm

Hi Matt, sounds similar to mine! Rhd ones seem rare as hens teeth. There's two different types of switch too. I think the RS6 had the chunkier switch like the facelifts. there's also a headlight switch fitting guide under the A6 c5 section. Please note both types of switches below:

I'd recommend a diagnostic check to see if any fault codes flag up. Or get the car to an auto electrican

Tracking after spacers is recommended. Regarding exhausts my brother and friends have used powerflow exhausts and been happy with the results and quality.

Yea I think they're the same

Keep us posted on how you get on 🙂

No probs at all. Yea you might find it just starts working again as it did for me

If you've got intermittent electrical issues then the water could be affecting your Comfort control module (CCM) located under the front passenger footwell carpet. I too are experiencing electrical issues and have a suspicion that waters getting in mine again. Trim and carpet needs to come up to access it. My plan long term once I replace the CCM is to have it relocated to the glovebox.

Could definitely be a sensor. If it's hit or miss then it definitely could be electrical.

No probs. Most garages do I think because of the Christmas break

Can't say I've heard of similar cases. That's a new one on me, the car learning how you drive.

Could it be the exhaust banging on the underside of the car? Or engine or gearbox mounts

I'd recommend a diagnostic check to see if any fault codes flag up. If you take it to Audi I'd expect to see some form of good will on the repair despite being out of warranty

I'd definitely be looking at failing engine or gearbox mounts in my opinion

Glad you got some sort of resolution. Let's hope it is just a clip.
