Clutch switch solved my non working cruise control. All good now.

I just had this exact problem, so I’ve had the joy that is reading countless threads on it. My upper clutch switch (black/white casing) failed and I couldn’t get the cruise control to engage. This is the switch that disengages the CC if the clutch pedal is depressed.

The lower switch has a blue casing and allows the car to start without depressing the clutch. Apparently, it’s also the switch that causes the revs problems, when changing gear. (Didn’t have this problem, so I can’t be sure)

Here are the part numbers

Upper Clutch Switch (Black/white casing) 7H0927189
Lower Clutch Switch (Blue casing) 6Q0927189

They’re pretty cheap, so it might be worth changing both and be done with it. The upper one is dead easy to change, although there’s an order to changing the lower one and where the clutch pedal is when you put the new one in. Worth getting a pdf of the Audi manual before hand as it seems plenty of people have broken new switches, when replacing the lower one.

Surely the operation of these switches can be tested with VCDS to confirm they are the problem?

Nope. But the symptoms are always the same, so easy to diagnose.

I think they updated the part a few years ago and the part changed colour.

They are easy to change and about £18 each to buy. I just changed mine as a sensible precautionary measure even though it wan't failing.

Paul,

The part numbers and casing colors I’ve mentioned in my post above are the latest numbers. The original parts were updated with new part numbers in the last couple of years. The same reason you’re getting confused, is why I ended up reading endless threads. So, I can guarantee they are the latest part numbers.

It’s not a UK/EU website but here are links that show the parts and also the previous revisions for each part.

I also changed this upper clutch switch out last year due to no cruise control / holding down of starter button and used part no. 7H00927189. Bought from a local stealer and the casing was black/white £22.

This was the helpful link viewtopic.php?f=35&t=114660#p731104 I used to install as I didn't want to be breaking it after reading the plunger mechanism can be easily damaged if not installed in a certain way.
