E63 M6 PLCD / Clutch Postion Sensor

[Nat_H]

Looks like my PLCD / Clutch postion sensor is on its way out.

Anyone had this replaced recently, and is it a simple part swap, or does the clutch need to have an adaption cycle run ?

Also, any idea on price ?

Thanks
Nat

I'd need to check with my indie who got the fault codes, but I recall them saying there were 3, all relating the clutch position sensor.

I get the yellow cog after 30 miles of driving or so, but not on every trip. No slip on the clutch, and good changes irregardless of the revs, with a slight "clunk" present on 1st - 2nd, but again, not on each change.

My local indie does not have the software to do adaptation, but I have found another one who can.

The part is £318 + fitting.

Edit to add - Thanks for the reply, reading you other posts regarding the gearbox, you certainly know your stuff.

I've bought 230 178 374 28, which was around £318.

It fits to the top of the gearbox, and i believe it can fitted without opening the gearbox.

Just a quick update to say that I had the PLCD replaced, and its corrected all my errors (red and yellow cogs), jerky gear changes, and clunk from 1st to 2nd.

The sensor was £315, fitting and clutch adaption was around £200.

Nat, which errors were you getting re the clutch problems?

Was it like this?



How was it diagnosed? What were the other symptoms?

I've been quoted £286 for the sensor from BMW

I may just get it changed along with the clutch and flywheel at some point. The warranty thing really is 50:50 and I don't want to pay nearly £3000 with parts and labour from BMW when it can be done for around £1500.00.

First time it happened, I was around 30 miles from home, 40 mph in 4th, on flat ground, and the red cog popped up. I did not try to change gear at the time, or when the red cog was up.

It lasted for 4 - 5 mins, randomly flicking between red and yellow cogs.

Then is cleared itself, and car drove as good as normal on the rest of the trip and on the way home.

It happened again about 2 days later, again when the car/gearbox was warm. This time I had no choice but to change gear as I was in traffic. Gear change was slow, with no clutch finesse, and trying to pull away smoothly was near impossible, very jerky, and really scary as I thought I was about to kill my car. Again after 5 mins or so, and the random flicking between red and yellow cogs, it cleared.

From all this I assumed that it was not mechanical, having had a TVR, you get a feel for sensor vs mechanical issues.

I called a local Indie to me, MVT near Wareham, who agreed with my theory. Ordered the sensor from BMW, I paid £316, and then a couple hours of labour to lower the gearbox to replace the sensor.

It drives great now, and no signs of red/yellow cogs. (touch wood)

It went to MVT in Poole - mvtpoole.co.uk

Hope this helps.
